How Does A Camera Shutter Work

The shutter is a gateway that lets the light go into the sensor to take a photo; after that, it closes very sharply to stop the exposure. Different cameras have different types of shutters designed according to their function. A shutter is a complex combination of simple machines that work together differently; it depends on either a DSLR, mirrorless, video, or motion picture camera. First of all, have a look at the DSLR’s shutter, how that works. Before all, you should understand shutter speed, and it would give you deep insights into how a camera shutter works and its mechanism.

Shutter Speeds

Shutter speed is one of the most basic and crucial settings in photography. The measurement of time in which the shutter stays open is called the shutter’s speed.

In the above picture, you can imagine how does shutter speed affects the image quality. If you use a high shutter speed, such as 1/500th of a second, the image quality will be fine. In contrast, the low shutter speed produces motion blur, like 1/4th of a second.

The long shutter speed is used in moving objects like bikes, cars, and flying birds to create a blurry effect in the direction of motion.

On the other hand, low shutter speeds are effective in shooting the milky way.

To measure the shutter speed, we use small units of time like mili; for instance, 1/5oo means five-Hundredth of a second or 500 milliseconds.

Now, we see how a shutter works in both the DSLR and mirrorless cameras.

How Does DSLR Camera Shutter Work

A DSLR is a device composed of a mirror and a prism. This composition helps you to see the subject entered through the lens. A camera mirror is placed after the lens directly; therefore, light can not strike the shutter. A DSLR camera mirror goes up when you press the shutter button to open it and make an exposure.

After pressing the shutter button, you can hear the hitting sound of a mirror going up. A mirror does not reflect light behind the lens, reflecting the viewfinder to produce a black screen.

During this, the shutter’s curtain down to expose the sensor, and when exposure completes, the second curtain covers the sensor. The duration between both the curtains when they go down depends on the shutter speed. If we adjust the shutter’s speed to high, they will remain open for a longer time and vice versa.

How Does A Mirrorless Camera Shutter

These cameras have no mirror inside them as DSLR do; therefore, these are called mirrorless. An image data is transmitted through the sensor to an electronic screen in the viewfinder that helps you see your subject. The shutter in the mirrorless cameras has screens, but it proceeds differently.

The sensor is not covered behind the lens in the mirrorless cameras because the mirror is absent. But, a shutter’s door goes up and covers the detector at once. Afterward, it goes down to make an exposure, and the other door goes down from the frame.

After understanding the working of a shutter in two different types of cameras, we concluded that the working principle of a shutter is almost the same. Now we see the working of different shutters and their mechanism.

There are two types of camera shutters, an electronic shutter, and a mechanical shutter.

How Does An Electronic Camera Shutter Work

The electronic camera shutters have no physical moving parts; they just on/off the sensor to allow the light into the sensor. Therefore, these shutters are cheap.

How Does A Mechanical Shutter Works

The mechanical shutter has two curtains, the front and rear curtain. The mechanical shutter is located in front of the sensor. These curtains are open and close to produce exposure.

How Does A Leaf Shutter Works

The leaf shutter is usually present in the lens’s body, and it consists of identical blades or leaves open and closes outwards and inwards, respectively. A photographer can adjust the period between the opening and closing of the shutter.

Leaf shutters are faster than the other shutter’s mechanism. Therefore, you can use them to produce high sync flash having 1/1000th of a second.

How Does A Focal Plane Shutter Works

The Focal Plane Shutter is situated in front of the image plane. This shutter is made of two blinds overlapping to form a window. A focal-plane shutter can operate mechanically by spring or electronically. A photographer presses the shutter button as one of the two curtains moves horizontally in either right or left direction to expose the film. The second curtain takes the first to cover the movie; this time depends upon shutter speed. If shutter speed will high, the period will be low and vice versa. The exposure time can be as shorter as 1/12000th of a second.

A focal-plane shutter can be operated in two ways, mechanically and electronically. The mechanical shutter is used in most digital cameras, but the electronic shutter is used in small and cell phone cameras. Some digital cameras have both mechanical and electronic shutters. However, cameras having a mechanical shutter give better image results than electronic shutters because the mechanical shutter optimizes the sensor’s capacity to collect and gather the image.

How Does A Shutter Work While shooting Videos

If you are using a mirrorless camera or DSLR while shooting a video, your camera’s shutter goes up until you finish it. A camera can shoot limited frames per second, which is not viable while shooting a video. The camera sensor employs a shutter when you are shooting video and scanning the light electronically.

FAQs

Q: At What shutter speed can I get sharp images?

According to the thumb rule, your shutter speed should 1/Focal Length; in other words, if you use a lens of 500mm focal length, you should set the shutter speed to 1/500th of a second or faster.

Q: What happens when the camera's shutter opens?

When you hit the shutter button, it opens and exposes the sensor to admit light reached into the sensor. The shutter closes immediately after open; the length of time depends on the shutter speed.

Q: Which shutter gives us a sharp image?

A focal-plane shutter would be merely better because it is faster than others. Additionally, mechanical control makes it better to control light.

Q: In how many directions do the focal plane shutter can move?

New cameras with focal-plane shutters can move left to right or right to left.

March 29, 2021 By Muhammad Ahmad Leave a Comment

How To Fix Scratched Camera Lens

The lens is the main component in the camera because the image’s quality depends on it. Sometimes the camera’s lens gets scratched during cleaning or changing. It will be hard to remove deep scratches, but if scratches are not deep, you should remove them using ordinary methods at home. Otherwise, you should contact the manufacturer to fix this problem. After all, if scratches do not repair, you will have to change the lens to get better photography results.

Here, I would like to discuss some ordinary home-based tips to remove the scratches. These methods may remove the scratches totally or partially.

1) Rub With Alcoholic Solution

First of all, you should clean your lens before rubbing to remove the scratches because dust can cause more marks on the lens. It would help if you used a fine microfiber cloth and lens cleaning solution for cleaning purposes. Please do not try to apply the cleaning solution directly to the lens because it can damage it; dip the microfabric in the solution, then apply to the lens gently. Now, wait till it dries out. Take rubbing alcohol and make a diluted solution of 3.5% concentration by taking one part of rubbing alcohol; mix it in twenty amounts of water.

Method To Make A Solution

For example, you have rubbing alcohol of 70% concentration, take 5ml from this, and mix it into 100ml water. You will get a solution of 3.5% concentration.

How To Apply

Now, take a microfibre cloth piece, dip it into a rubbing solution and start massaging gently on the lens. Repeat it and check out the scratches; they will begin to disappear. After this, leave your lens to dry out.

2) Use Petroleum-Based Vaseline

It is available everywhere easily at a low price. Before starting, you should clean your camera lens with a microfibre cloth and a cleaning solution. Then, take an adequate amount of vaseline using a microfiber cloth, start rubbing gently, and repeat this three to four times. Stop, and check whether scratches disappear or not; if you feel some scratches are left, you can repeat the process.

After the procedure, you should clean your lens again using a microfiber cloth and a cleaning solution because Vaseline catches dust particles rapidly.

3) Eraser Method

In this method, you need a fresh soft white eraser to eliminate the scratches. Before proceeding, you need to clean the lens. For this purpose, you can use LensePen for better cleaning. Now, take a rubber, hold it firmly, and start erasing in the direction of scratches. You need to rub slowly and proceed with it until you feel scratches disappear.

4) Windscreen Polish Method

Commonly, the car’s windscreen scratched during travelling. We can use windscreen polish to diminish the scratches because both are glass-based. It is necessary to clean the lens before the scratch removing process. You can use either technique, LensPen, or a clean lens solution.

Moreover, windscreen polish may remove scratches altogether and refresh the coating of the lens.

It would help if you used a microfiber cloth to apply the windscreen polish because it works gently on the lens. After dipping it into the polish, rub it on the lens and repeat if need.

5) Toothpaste Method

Clean your lens before removing the scratches to get excellent results is mandatory. You can use ordinary white toothpaste to remove scratches because it has slightly rubbing properties. You can use a delicate cotton bud for scratching or a microfiber cloth. Take a bit of toothpaste with the help of cotton bud or microfiber cloth and apply it longitudinally softly until scratches on your lens are removed. You can use more buds if needed.

After removing scratches, you should clean your lens again with a lens cleaning solution.

6) Camera Lens Repairing Kit

Another option to remove lens scratches is a repairing kit. It contains several hand-held tools and solvents, which can help you repair your camera lens.

You can use this kit to repair your lens.

FAQs

Can the lens scratch remove?

It depends on scratches; if they are deep, then they may hardly remove. If scratches are shallow, you can remove them using various methods, like the Vaseline method, toothpaste method etc.

Do scratches low the image quality?

Yes, scratches may decrease the image quality, but it depends on the scratches size. If your camera has minor scratches, it may have a negligible effect on image quality and vice versa.

Secondly, focus and contrast may increase or decrease the effect of scratches.

🥇 How To Shoot Time Lapse Video?

March 22, 2021 By Muhammad Ahmad Leave a Comment

How To Shoot Time Lapse Videos

Shooting time-lapse videos began in 1872 by a photographer named Eadweard Muybridge. He shot off a running horse. Afterwards, a new horizon of time-lapse videos started. Nowadays, making time-lapse videos has become a complete profession, and photographers make videos for various purposes like an advertisement, research work, and cast lengthy events in a short time, such as to show a construction work off to a customer in a short time.

Making time-lapse videos is an excellent experience because you can see them in a few seconds or minutes after shooting a very long video. You can take an overview of how a flower is blooming, a breathtaking view of the sunrise and set, and people’s activities at the busiest place in a short time.

There are two methods to make a time-lapse video, the first one using videos, and the second using various photos.

How Can You Make A Time-Lapse Video by Using Videos

In this method, you can use your android phone or iPhone to switch on the camera and press the “Time-Lapse” button to start shooting a video. It would be best to place your phone safely while shooting because a movement or shake can spoil your video. Some phones do not have a Time-Lapse button by default, don’t worry, you can easily download it from the play store.

How Can You Make A Time-Lapse Video By Using Photos:

You can shoot a time-lapse video by stitching multiple still images, and events may have the length of minutes, hours, days, weeks, or months. After capturing the video, you can play it with great speed to compose a time-lapse video. The time interval between the two photos depends upon the event’s duration.

To capture the time-lapse video, you have to arrange some hardware to capture the video successfully. The required hardware will include in the following articles described below:

1. A Camera

2. An ND Filter

3. A Tripod

4. An Intervalometer(In case of your Camera has not.)

5. A Memory Card

6. Sight Where To Shoot

1) A Camera:

A camera is a practical component used in time-lapse photography. You can use multiple ranges of cameras for this purpose; for instance, Canon EOS R6 released on 9th July 2020 with an RF lens and 20Mp sensor is a good camera. Another example, Canon EOS Rebel SL3 with a 24.1Mp sensor and EF-S lens you would use.

2) An ND Filter:

A Neutral Density Filter(ND Filter) plays a vital role on sunny days to get clear images for time-lapse videos. An ND filter helps to drop ten stops exposure, 1000X darker to make a time-lapse video ideal.

3) A Tripod:

A tripod helps you to hold a camera for a long time when you shoot a time-lapse video. A tripod also prevents your camera from moving. The slightest movement in camera position, focus, or exposure can spoil the result of the movie. So you should lock your camera on a tripod before the shoot the video.

4) An Intervalometer:

An intervalometer helps you to take several pictures in a specific time interval. It frees you from touching a shutter while taking pictures. You can take numerous images with the help of an intervalometer.

5) A Memory Card:

Suppose you have a memory issue with your camera. In that case, you can use an external memory device to cope with this issue because when you shoot a very lengthy video, it may include in weeks or months, you may face a memory issue. I recommend you a 32GB or above-capacity memory card.

6) Sight Where to Shoot:

There are various sights to shoot time videos around you. You can shoot a video as you need. For example, you can shoot in the city center to overview the activities of the people.

Procedure

1) Shooting Mode:

After choosing the right place to shoot, lock your camera on a tripod and place it in the best place. Now, switch your camera on manual mode for better control over the shot. Manual mode will prevent you from a sudden change in exposure due to clouds because you require constant exposure to get better results.

2) Focus:

It is an essential thing in time-lapse photography to focus your camera. It would be best if you did this in manual mode. Before shooting, you should concentrate your view carefully.

3) Interval Setting:

If you take a considerable interval between two events, it will hard to see the relationship between the two events. Here are some gaps to guide you.

a) In a cityscape, you can take one photo per second.

b) For a landscape where clouds are moving fastly, it is one shot per three seconds.

c) In the landscape without clouds or slow-moving clouds, it would be one photo per five to ten seconds.

d) If you are shooting in a day-night transition, it would be one photo per thirty seconds.

e) If the night is with a full moon, it would be one photo per eight to twelve seconds, and with stars, it would be one photo per twenty to thirty seconds.

3) Shutter Speed and Motion Blur:

For time-lapse photography, the shutter speed should be double your frame rate. For instance, if you are shooting at 30fps, then you can set your shutter speed at 1/60 of a second.

After combining the captured photos, you will make a video and play it at the precise speed at which you can see, recognize, and distinguish between moving objects. It is only possible if you reproduce at 30fps.

4) ISO Settings:

ISO is the camera’s ability to gather light. Higher ISO ratings enhance the film’s ability to take photos in low light. You need to set it at the lowest rate if it is sunny.

5) An ND Filter:

To control an excess amount of light for better results in a time-lapse video, you should use ND filters. An ND filter does not disturb your shutter speed.

6) Use Intervalometer For Automatic Shuttering:

It prevents you from pressing the shutter manually for each photo.

Note: Before start making takes some test shots to make sure that your focus and exposure are good.

You should take a photo in 4-by-3 size, not in 16-by-9 because it will help you crop it later. You can zoom in without losing quality. You also can create an MP4 video.

FAQs

Can I make a time-lapse video on my iPhone, and how?

Yes, of course, you can make a time-lapse video on your iPhone because iPhone has this feature. Switch the camera on and go into settings and select the time-lapse video option.

My camera has not intervalometer; can I make a time-lapse video without it?

It is tough to make a time-lapse video without an intervalometer. You can buy this device separately from a market and attach it to your camera.

I want to make a time-lapse video in the middle of the day in summer; which filter should I use to overcome light?

ND filter is the best option to cope with this problem.

HOW TO CLEAN YOUR CAMERA LENS

The lens of a camera is an essential and sensitive part of a camera, and it needs very special and great care to give magnificent results in photography. A photographer should need great care of his camera and lens to become an excellent and successful photographer, and he should do this. In photography, we need clear images with no extra spots or marks on them; if so rating of images will fall rapidly.

Here I am going to tell you better but simple ways to keep your camera’s lens clean. These methods are improved, practical and convenient to use. You should apply these methods after using the camera if needed, and after that, you should pack the camera in a polythene bag properly; it will provide extra care to your camera. Cleaning the lens of a camera regularly after use can increase the life of the camera.

Use a Blower

Firstly, you can use a blower to remove dust particles and residues safely. You should not blow during cleaning because your saliva and breath moisture could increase condensation, which results in stubborn spots on the lens; for this purpose, you should use a blower of good quality. It would help if you used blowers only for cleaning lens to get better results.

how to clean your camera lens by thevloggingtech.com

Cleaning Air Blower Duster for lens without physical contact is the best cleaner with air inlet valve design prevents air backflow from nozzle priced only $8.99.This blower removes dust and erases smudges gently from the soft lens. You can buy this blower online on Amazon.

Use a Brush

Secondly, if you feel some residues and specs on the lens after using a blower, you can use a lens brush for cleaning. We suggest a lens brush with camel hair due to its softness and good cleaning properties. Camel’s hair is thin and less harmful to the lens. Some companies make goat’s hair brushes instead of camels. Keep in mind brushes can pick a lot of needless.

Please Do not feel the brush with your hands. It may seem unimportant, but if the oils on your hand get to the lens, it could damage. Use a brush for cleaning gently to get rid of dust particles. Lenses’ brushes are of low price and available easily everywhere.

Use a LensPen

For cleaning the camera’s lens, you can use LensPen instead of a lens brush for better results. LensPen is twice likely to clean the lens as a brush in an easy way. The LensPen tip has made of the softest suitable materials, assembled in a “clean room,” free of unwanted substances. LensPen can remove oily fingerprints and dust better than a brush. The cleaning tip of the LensPen has infused with a unique carbon compound.

Carbon molecules have a unique ability to absorb vast amounts of oils and contaminants. LensPen is pocket-size and easy to use and carry everywhere. It is unaffected by temperature, even in the desert heat and arctic cold. LensPens have no expiration date and will provide up to 500 cleanings. LensPens cannot dry out even in complex weather conditions. LensPen original has designed for all-optical devices and 11 cm long with a safety cap having a round concave tip for better cleaning.

Use a Lens Cleaner Solution

Thirdly, we can use a camera lens cleaner for this purpose. Most solutions are alcohol-based and evaporate quickly. Only two to three drops probably would not leave any spots or streaks. Do not spray the cleaner directly on the lens; it may damage the lens. To clean up the lens, use lens cleaning microfiber cloth or soft white Tissue because other stiff fabric will cause scratches on the lens. Vius lens cleaner spray gently cleans fingerprints, dust, and oil.

Use Special Microfibre fabric or Tissue

When you use camera lens cleaner, make sure you clean it with either a microfiber lens cloth or specific lens cleaning tissues. Don’t use regular tissues as they could scratch your lens. In the market, more recent and cheap tissues are available for this purpose that works. These are safe but for only single use. You can purchase tissues and clothes online.

Disadvantages of Much Cleaning the Lens if Not Need

Lastly, clean your lens as little as possible because sometimes your lens will get a bit dirty, but if you are frequently keeping up with every single spec of dust, you can end up doing more harm than what was there to begin with. Your camera lens is very fragile, so only clean it, if it is of top priority.

FAQ:

Q: How do I perform a dirt test on a DSLR lens?

Ans: 1) Adjust the focus, set your camera to manual mode. Then turn the focus ring to infinity. Doing so will allow you to see specs of dust in the viewfinder.

2)Look for a smooth surface and take an image of it. For more precise results, make a two-shot approach. Take a photo of both light-coloured and dark-coloured surfaces, so you can easily spot dust particles on the images.

3) Put your camera in playback mode and zoom on each photo, carefully check the pictures for any misty spots or dust particles if you dust, and clean your lens.

Q: What tools do I need for cleaning my DSLR camera lens?

Ans:1 ) Air Blower: Using an air blower and a soft-bristled brush can remove as much dust as you can.

2)Add one or two drops of lens cleaning fluid to a microfibre cloth or a cleaning wipe.

3)Starting from the outer part, the lens in a circular motion going to the centre and gently remove fingerprints, oil, dirt and dust.

Q: How can I keep my camera lens clean?

Ans:

Do not forget to contact the lens cap before putting your camera in a bag.
Avoid placing the camera in dusty areas.
Always contact the lens cap when you are not using your camera.

Q: How can I avoid my camera lens getting dusty?

Ans: Canned or compressed air can blast and destroy the camera lens. If you feel the need to remove the dust from your lens, use a manual blower because a blower is not as pressurized as canned air.

🥇 How To Clean Your Camera Sensor

HOW TO CLEAN YOUR CAMERA SENSOR

The camera has become an essential part of our lives, especially for professional photographers who shoot many different photos and videos in their daily professional lives. For this purpose, they have to use other cameras like DSLR cameras, adventure cameras, compact cameras and film cameras, etc.

The camera sensor is an essential part and is responsible for the image quality, which converts light signals into digital signals. Sometimes photographers have to change lenses for various purposes; during this period sensor of a camera exposes to open-air, which causes dust on the surface of a sensor. Dust causes a low-quality image, which is not acceptable by professionals. To cope with this awful problem, I am going to give you some caring and comfortable tips.

How Can You Detect Dust On The Sensor?

Firstly, you have to detect the dust on the sensor by following a few steps.

Set your camera aperture to the small gap and also to the lowest ISO.

Take a picture of a maximum white and shiny surface and then move the camera slightly, which helps you faint the image and dust more visible.

You can load the image on your PC to see the dust easily.

After detecting the dust particles, you will have to clean them to enhance your photographs’ quality; therefore, you should follow the practically proven instructions by world-class professional experts. Consequently, you will save your camera sensor from damage and scratches on it.

Should I attempt auto cleaning?

Yes, of course, you should apply first auto cleaning before manual cleaning because it may save the sensor. You would have to full the camera’s battery because the low battery could harm your camera if it has turned off during cleaning.

Precautions Before Cleaning the Sensor

Fully charged your camera’s battery because if the battery becomes low while cleaning, as a consequence, the mirror will damage.

It is necessary to clean the camera’s outside surface because dust particles stuck to the outer body could enter the camera and reach the sensor.

Clean the operational area where you will perform the cleaning because it is twice likely to enter dust particles in the camera to the sensor if the working space will not clean.

After all, make sure that you have collected all the necessary tools like air blower, sensor cleaning fluid, delicate tissues, microfilament cloth, etc.

If you want to have complete cleaning kit, click here.

Dry Cleaning Method

We need some tools for this purpose, like a manual air blower to remove the dust particles and a sensor scope to check the remaining residues quickly.

Lay the camera on a dry and soft rig and do not touch internal parts while cleaning. Start blowing the sensor off with great care. The position of the camera should upside down during cleaning.

Warning: Never use compressed air because it may cause damage to the sensor.

Use sensor scope during cleaning to find dust particles easily and then remove them using a blower. However, you can repeat the process if you feel that some particles are still not released.

I suggest Delkin Sensor Scope, 5x digital DLR Sensor with the cover case, priced about $50. Sensor Scope will help you to find tiny and microscopic dust particles. It has a flashlight that will help you to find tiny threads even in daylight. Sensor Scope can easily cope with four types of contaminants, like metallic, fibre, organic, and quartz particles. Sensor Scope is only a device that can detect and remove dust particles easily.

The Sensor Scope device is easy to use. It has a 5x magnification lens and four ultra-bright LED lights, which gives extra insight into the camera to judge the microscopic particles.

Zoom the Sensor Scope about 50% to 70% to check out the smallest dust particles, and clean them carefully. On a technical basis, tiny particles don’t disrupt the image’s quality; you need not inconvenience about that much.

Wet Cleaning Method:

For wet cleaning, you can use special brushes working based on electrostatic principle; these brushes can clean the sensor by slight touch to the sensor, which doesn’t harm or damage the sensor. The tools required for wet cleaning are Arctic Butterfly Brush, Green swabs, Sensor Clean Solution, and Smear Away Solvents.

Before starting wet cleaning following steps are to be needed.

After removing the lens and lying down the camera on a floor while keeping the LCD face towards the floor.

Switched on the manual cleaning button to lock up the mirror because it can disrupt the cleaning process.

After removing the sensor swab, use a manual air blower to remove odd particles.

Wet the swab with two to three drops of solution only, avoid over wetting the swab, drag the swab from one edge to the other of the sensor.

Do not try to squeeze the liquid out; let it dry for just a minute.

It has often observed that brushes do not clean the sensor optimally; therefore, we have to use smear away solutions to clean maximum. These solutions will help to clean your sensor. In this regard, I would like to use an EZ sensor cleaning kit.

It is crucial to clean the sensor’s surroundings because they can cause dirty the sensor again.

It would help if you keep cleaning your camera sensor as long as possible by following the simple tips given below:

At the time of changing the lens, keep your camera in a clean, dust-free area.

Before recapping your lens optics, clean it and avoid the unwanted change of the lens.

The bag or drawer where you place your camera should clean.

It is predicted that people will follow the instructions to keep their cameras with great care.

FAQ:

Q: How can I clean my first DSLR camera sensor for the first time?

You can follow the step by step instructions given in the article above confidently. These instructions are technically approved. However, when you use new ultra swabs, you should use them with a bit more pressure and double the solution(6-8 drops) to make them thicker and more absorbent.

Q: What are the differences between sensor swab and sensor swab ultra?

In the newly designed ultra swab honeycomb pattern, it improved the efficiency of cleaning by covering more surface area and more absorbent and softer. The design of the new ultra brush is designed in a manner to protect the corners of the sensor.

Q: Which solution should I use to clean the Sony Camera sensor?

I recommend the Eclipse solution for all Sony cameras because this is safe and do not damage the sensor surface. Furthermore, you can also use Aeroclipse safely.
