All about Aperture the ‘f’ No in your DSLR

Posted on

Aperture is one of the three pillars of photography, the other two being ISO and Shutter Speed. Without a doubt, it is the most talked about subject, because aperture either adds a dimension to a photograph by blurring the background, or magically brings everything in focus. In this article, We will try to explain everything known about aperture in very simple language.

Digital Camera Modes-Explained for You

Posted on

let us understand the digital camera modes is essential to control the exposure in photography. As a good Photographer, you should know what each camera mode does and when it should be used, under what circumstances.


1) What are Digital Camera Modes?

Digital Camera Modes allow photographers to control the parameters of an exposure, specifically, Shutter Speed, Aperture and ISO. While certain modes can fully automate the camera exposure, there are other modes that let the photographer manually control some or all parameters of the exposure.

Today, most digital cameras have various types of camera modes that can be used in different situations. While most point and shoot cameras concentrate on automatic modes for simplicity’s sake, more advanced cameras feature modes that allow both automatic and manual exposure control.

2) Types of Camera Modes

Here are the four main types of camera modes that can be found in most digital cameras today:

  1. Program (P)
  2. Shutter Priority (Tv) or (S)
  3. Aperture Priority (Av) or (A)
  4. Manual (M)

3) Program Mode

In “Program” mode, the camera automatically chooses the Aperture and the Shutter Speed for you, based on the amount of light that passes through the lens. This is the mode you want to use for “point and shoot” moments, when you just need to quickly snap a picture. The camera will try to balance between aperture and shutter speed, increasing and decreasing the two based on the intensity of light. If you point the camera to a bright area, the aperture will automatically increase to a bigger number, while keeping the shutter speed reasonably fast. Pointing the camera to a darker area will decrease the aperture to a lower number, in order to maintain a reasonably fast shutter speed. If there is not enough light, the lens aperture will stay at the lowest number (maximum aperture), while the shutter speed will keep on decreasing until it reaches proper exposure.

I personally never use this mode, since it does not give me much control over the exposure. There is a way to override the camera-guessed shutter speed and aperture by moving the control dial (on Nikon cameras it is the dial on the back of the camera). If you rotate the control dial towards the left, the camera will decrease the shutter speed and increase the aperture. If you rotate the dial towards the right, the camera will increase the shutter speed and decrease the aperture. Basically, if you needed to get a faster shutter speed for freezing action, you would rotate the dial to the right, and if you needed to get a large depth of field, you would rotate the dial to the left.

4)Shutter-Priority Mode

In “Shutter Priority” mode, you manually set the camera’s shutter speed and the camera automatically picks the right aperture for you, based on the amount of light that passes through the lens. This mode is intended to be used when motion needs to be frozen or intentionally blurred. If there is too much light, the camera will increase the lens aperture to a higher number, which decreases the amount of light that passes through the lens. If there is not enough light, the camera will decrease the aperture to the lowest number, so that more light passes through the lens. So in Shutter Priority mode, the shutter speed stays the same (what you set it to), while aperture automatically increases and decreases, based on the amount of light. In addition, there is no control over subject isolation, because you are letting the camera control the depth of field.

I try not to use this mode either, because there is a risk of getting an overexposed or underexposed image. Why? Because if the amount of ambient light is not sufficient and I set the shutter speed to a really high number, my exposure will be limited to the aperture/speed of my lens. For example, if the maximum aperture of my lens is f/4.0, the camera will not be able to use a lower aperture than f/4.0 and will still shoot at the fast shutter speed that I manually set. The result will be an underexposed image. At the same time, if I use a very slow shutter speed when there is plenty of light, the image will be overexposed and blown out.

5) Aperture-Priority Mode

In “Aperture Priority” mode, you manually set the lens aperture, while the camera automatically picks the right shutter speed to properly expose the image. You have full control over subject isolation and you can play with the depth of field, because you can increase or decrease the lens aperture and let the camera do the math on measuring the right shutter speed. If there is too much light, the camera will automatically increase the shutter speed, while if you are in a low-light environment, the camera will decrease the shutter speed. There is almost no risk of having an overexposed or an underexposed image, because the shutter speed can go as low as 30 seconds and as fast as 1/4000-1/8000th of a second (depending on the camera), which is more than sufficient for most lighting situations.

This is the mode that I use 95% of the time, because I have full control over the depth of field and I know that the image will be properly exposed under normal circumstances. The metering systems in most modern cameras work very well and I let the camera calculate and control the shutter speed for me.

6) Manual Mode

As the name suggests, “Manual” mode stands for a full manual control of Aperture and Shutter Speed. In this mode, you can manually set both the aperture and the shutter speed to any value you want – the camera lets you fully take over the exposure controls. This mode is generally used in situations, where the camera has a hard time figuring out the correct exposure in extreme lighting situations. For example, if you are photographing a scene with a very bright area, the camera might incorrectly guess the exposure and either overexpose or underexpose the rest of the image. In those cases, you can set your camera to manual mode, then evaluate the amount of light in darker and brighter areas and override the exposure with your own settings. Manual mode is also useful for consistency, if you need to make sure that both shutter speed and aperture stay the same across multiple exposures. For example, to properly stitch a panorama, all shots that you are trying to put together need to have the same shutter speed and aperture. Otherwise, some images will be darker, while others are lighter. Once you set the shutter speed and aperture to the values of your choice in manual mode, your images will all have consistent exposures.

Shutter Speed the important Element in Photographing Good Pictures

Posted on

Shutter Speed is one of the three pillars of photography, the other two being ISO and Aperture. Shutter speed is where the other side of the magic happens – it is responsible for creating dramatic effects by either freezing action or blurring motion. In this article, I will try to explain everything I know about shutter speed in very simple language.


1) Understanding The Camera Shutter?

It is highly recommend reading about what a DSLR is and what it consists of. Simply put, a camera shutter is a curtain in front of the camera sensor that stays closed until the camera fires. When the camera fires, the shutter opens and fully exposes the camera sensor to the light that passes through the lens aperture. After the sensor is done collecting the light, the shutter closes immediately, stopping the light from hitting the sensor. The button that fires the camera is also called “shutter” or “shutter button”, because it triggers the shutter to open and close.

2) What is Shutter Speed?

Shutter speed, also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor. If the shutter speed is fast, it can help to freeze action completely, as seen in the above photo of the dolphin. If the shutter speed is slow, it can create an effect called “motion blur”, where moving objects appear blurred along the direction of the motion. This effect is used quite a bit in advertisements of cars and motorbikes, where a sense of speed and motion is communicated to the viewer by intentionally blurring the moving wheels.


Slow shutter speeds are also used to photograph lightning’s or other objects at night or in dim environments with a tripod. Landscape photographers intentionally use slow shutter speeds to create a sense of motion on rivers and waterfalls, while keeping everything else in focus.

Motion can also be frozen to an extent with a camera flash, even at low shutter speeds.


It was getting dark and even after increasing the sensor sensitivity to ISO 800, the camera still needed at least 1/250th of a second to properly expose this bird. If I had shot the bird at that speed, the bird would have turned out to be blurry, since it moved faster than 1/250th of a second. I used an external flash and fired the camera at 1/250th of a second and as you can see, it helped me freeze motion, despite having a low shutter speed for a bird in flight.

All of the above is achieved by simply controlling the shutter speed. In summary, high shutter speeds freeze action, while low shutter speeds create an effect of motion.

3) How Shutter Speed is Measured

Shutter speeds are typically measured in fractions of a second, when they are under a second. For example 1/4 means a quarter of a second, while 1/250 means one two-hundred-and-fiftieth of a second or four milliseconds. Most modern DSLRs can handle shutter speeds of up to 1/4000th of a second, while some can handle much higher speeds of 1/8000th of a second and faster. The longest shutter speed on most DSLRs is typically 30 seconds (without using external remote triggers).


4) Fast, Slow and Long Shutter Speeds

Fast shutter speed is typically whatever it takes to freeze action. For me, it is typically above 1/500th of a second for general photography and above 1/1000th of a second for bird photography.

Slow shutter speed is considered to be the slowest shutter speed that you can handle without introducing camera shake. Some of Nikon’s lenses such as the Nikon 70-200mm VR II have special image stabilization (also known as “vibration reduction”) technologies within the lens that can help photographers take pictures at very slow shutter speeds when hand-holding cameras, without introducing camera shake. Although it is important to know how to hold a camera, image stabilization can significantly help in reducing blur from shaky hands, thus allowing one to shoot at shutter speeds that normally would not be considered to be “safe” under the reciprocal rule.

How about long shutter speed? Long shutter speeds are typically above 1 second, when you have to use a tripod to get acceptably sharp images (for low-light/night photography or to capture movement).

5) How to Set Shutter Speed

Most cameras handle shutter speeds automatically through in-camera metering. When the camera is set to “Auto” mode, both shutter speed and aperture are automatically selected by the camera. When you shoot in “Aperture Priority” mode, you set the lens aperture, while the camera automatically sets the shutter speed.

There are two ways to manually set the shutter speed:
a) By setting the camera to “Shutter Priority” mode, where you set the shutter speed and the camera automatically selects the aperture.
b) By setting the camera to “Manual” mode, where you set both shutter speed and aperture manually.

I recommend letting the camera select the correct shutter speed for you. I personally shoot in “Aperture Priority” mode 99% of the time and I let my camera calculate the shutter speed for me.

6) How to Find Shutter Speed

Do you know how to find out what your camera shutter speed is set to? It is typically very easy to find the shutter speed. On Nikon DSLRs that have a top panel, the shutter speed is typically located on the top left corner:

If you look through the viewfinder, it should also be the number on the bottom left side of the screen. On most DSLRs, you will not see the shutter speed as a fraction of a second – it will typically be a regular number. When the shutter speed is slower than or equals to one second, you will see something like 1″ or 5″ (the ” sign indicates a full second).


If you still cannot find the shutter speed, set your camera to “Aperture Priority” mode, then look into the viewfinder and point at a really dark area. Remember the numbers in the display, then switch to a very bright area and see what number changes. The number that changes is your shutter speed.

Depth of Field the most important factor in photography.

Posted on


This images when you see you wonder why is it looking so good and attractive without any good face or scenery, yes you are right it is the way it is taken is why it looks so attractive.

You may have heard the term depth of field (DoF), but if you are new to photography you may not yet be taking advantage of how DoF can enhance your photos. A basic definition of depth of field is: the zone of acceptable sharpness within a photo that will appear in focus. In every picture there is a certain area of your image in front of, and behind the subject that will appear in focus.

This zone will vary from photo to photo. Some images may have very small zones of focus which is called shallow depth of field. Others may have a very large zone of focus which is called deepdepth of field. Three main factors that will affect how you control thedepth of field of your images are: aperture (f-stop), distance from the subject to the camera, and focal length of the lens on your camera. Let’s explain you in little more detail.

How does aperture control depth of field?

Aperture refers to the access given to light from the lens to the camera sensors. The size of your aperture (the diameter of the hole through which light enters the camera) controls the amount of light entering your lens. Using the aperture (f-stop) of your lens is the simplest way to control your depth of field as you set up your shot.

Large aperture = Small f-number = Shallow (small) depth of field
Small aperture = Larger f-number = Deeper (larger) depth of field

It may be easier to remember this simple concept: The lower your f-number, the smaller your depth of field. Likewise, the higher your f-number, the larger your depth of field. For example, using a setting of f/2.8 will produce a very shallow depth of field while f/11 will produce a deeper DoF.


How does distance control depth of field?

The closer your subject is to the camera, the shallower your depth of field becomes. Therefore, moving further away from your subject will deepen your depth of field.

How does the focal length of a lens control depth of field?

Focal Length refers to the capability of a lens to magnify the image of a distant subject. This can get complicated, but the simple answer is that the longer you set your focal length the shallower the depth of field. Example: Your subject is 10 meters (33 feet) away, using a focal length of 50mm at f/4; your depth of field range would be from 7.5 -14.7 meters (24.6-48 feet) for a total DOF of 7.2 meters (23.6 feet). If you zoom into 100mm from the same spot, the depth of field changes to 9.2-10.9m (30.1-35.8′) for a total of 1.7m (5.7′) of depth of field. But if you move to 20m (66′) away from your subject using the 100mm lens, your depth of field is almost the same as it would be at 10 meters using a 50mm lens.

Can I just have a point and shoot camera, or don’t know how to change those settings?

Even with a point and shoot camera, there are ways to control your depth of field. In the Scene Modes menu, look for a symbol of a human head, which is the setting for portraits. This will give you a narrow depth of field. In the same menu there is also a mountain symbol, which is a setting for landscapes, which will give you a deeper depth of field.

If you are a beginner with a DSLR there are some simple ways you can control depth of field and still use and automatic shooting mode. By choosing Aperture Priority mode you can set your aperture to get the depth of field that you want, and the camera will automatically set the shutter speed.

Can I vary the depth of field exactly for each situation?

Yes, but because changing your aperture affects your shutter speed, the result may not meet the needs of your image. For instance, if you are trying to increase your depth of field by reducing aperture size you will also need to increase (slow down) your shutter speed which could make your image blurry. Understanding how all these settings work together can increase your control over depth of field.

Is depth of field equally distributed in front and back of my focus point?

No, it’s usually about one third in front and two thirds behind your focal point, but as your focal length increases it becomes more equal.

How Does the depth of field improve my images?

Managing depth of field is one of the most important tools at your disposal, because having tack sharp images is one of the most important factors to getting that great shot. Knowing how to make the parts of your image you want sharp and the parts you want to be out of focus, is a great artistic tool to create great images.

What and How to use shallow depth of field?

Using a shallow depth of field is a good way to make your subject stand out from its background and is great for portrait photography. Shallow DoF can also be useful in wildlife photography, where you want the subject to stand out from its surroundings. This is also useful because many wildlife photo opportunities are low light situations, and increasing your aperture size will give you more light. Shallow depth of field is also effective for sports photography where many times you want to separate the athlete from the background to bring attention to them. The result of this should also help give you a fast enough shutter speed to freeze the action.

Shallow Depth of Field

When is deeper depth of field useful.

In landscape photography it is important to get as much of your scene in focus as possible. By using a wide angle lens and a small aperture you will be able maximize your depth of field to get your scene in focus.

See the difference in variance of depth of field settings

How to determine depth of field?

There are several on-line sites that will provide depth of field charts for your camera and lenses. Also, there are a number of apps available for smart phone users that can calculate it for you while you’re in the field. Most cameras have a DoF preview button which will give you a preview as you look through the eye piece. (This is probably the easiest and most under-utilized method.) Using this button may cause your image to appear darker as you view it through the eye piece, but not to worry. Your image will be properly exposed as long as you have the correct exposure settings.

Can we get entire Image in Focus and have a good Depth of Field ?

Yes, using what is called the hyperfocal distance. When you are focused at the hyperfocal distance, your depth of field will extend from half the distance to your focal point to infinity. Use a DOF calculator to find your hyperfocal distance. If you don’t have a DoF calculator, a good rule of thumb is to focus a third of the way into the scene. Using an aperture of about f/11 or higher with a wide angle lens will maximize your depth of field.

How to use Depth of Field in Macro Photography.

Because most macro images are produced in low light and with a longer focal length, the depth of field is often very shallow. Adjust your lens to the smallest aperture that the light will allow. It may also be necessary to increase your ISO to allow you to properly expose the image and to maximize your depth of field. Still, in many macro images your DoF may be very minute. With this very narrow focus it becomes necessary to use a tripod, because even the slightest movement of the camera will move your macro subject outside your depth of field.

Bokeh, the most admired feature

Bokeh (boh-ke) comes from the Japanese word meaning blur. This effect is produced by the out-of-focus areas in your image that are beyond the depth of field. Bokeh commonly refers to the pleasing circle shapes caused by the shape of the lens aperture. Usually created when shooting with your aperture wide open, such as f/2.8, bokeh can also be created with smaller apertures if the background is distant enough.

Bokeh using F1.2


summarize controlling depth of field:

Increase depth of field

  • Narrow your aperture (larger f-number)
  • Move farther from the subject
  • Shorten focal length

Decrease depth of field

  • Widen your aperture (smaller f-number)
  • Move closer to the subject
  • Lengthen your focal length

Take control of your depth of field. Understanding how these adjustments control your it will greatly improve your photography.

Happy Photography


Lets Explore the ISO in Photography.

Posted on Updated on

The Right ISO The ISO setting determines how sensitive your camera is to light and also how fine the grain of your image. The ISO we choose depends on the situation – when it’s dark we need to push the ISO up to a higher number, say anything from 400 – 3200 as this will make the camera more sensitive to light and then we can avoid blurring. On sunny days we can choose ISO 100 or the Auto setting as we have more light to work with.

It is challenging to take good pictures without a good understanding of how ISO works and what it does. Camera ISO is one of the three pillars of photography (the other two being Aperture and Shutter Speed) and every photographer should thoroughly understand it, to get the most out of their equipment. We will try to explain ISO as simple as I can.

Before we go any further, you should first understand how DSLR cameras work.

1) What is ISO?

In very basic terms, ISO is the level of sensitivity of your camera to available light. The lower the ISO number, the less sensitive it is to the light, while a higher ISO number increases the sensitivity of your camera. The component within your camera that can change sensitivity is called “image sensor” or simply “sensor”. It is the most important (and most expensive) part of a camera and it is responsible for gathering light and transforming it into an image. With increased sensitivity, your camera sensor can capture images in low-light environments without having to use a flash. But higher sensitivity comes at an expense – it adds grain or “noise” to the pictures.


The difference is clear – the image on the right hand side at ISO 3200 has a lot more noise in it, than the one on the left at ISO 200.

Every camera has something called “Base ISO”, which is typically the lowest ISO number of the sensor that can produce the highest image quality, without adding noise to the picture. Some older Nikon DSLRs and a number of other modern cameras such as the Fuji X-T2 have a base ISO of 200, whereas most modern Nikon and Canon digital cameras have a base ISO of 100. So, optimally, you should always try to stick to the base ISO to get the highest image quality. However, it is not always possible to do so, especially when working in low-light conditions.

Typically, ISO numbers start from 100-200 (Base ISO) and increment in value in geometric progression (power of two). So, the ISO sequence is: 100, 200, 400, 800, 1600, 3200, 6400 and etc. The important thing to understand, is that each step between the numbers effectively doubles the sensitivity of the sensor. So, ISO 200 is twice more sensitive than ISO 100, while ISO 400 is twice more sensitive than ISO 200. This makes ISO 400 four times more sensitive to light than ISO 100, and ISO 1600 sixteen times more sensitive to light than ISO 100, so on and so forth. What does it mean when a sensor is sixteen times more sensitive to light? It means that it needs sixteen times less time to capture an image!

ISO Speed Example:
ISO 100 – 1 second
ISO 200 – 1/2 of a second
ISO 400 – 1/4 of a second
ISO 800 – 1/8 of a second
ISO 1600 – 1/15 of a second
ISO 3200 – 1/30 of a second

In the above ISO Speed Example, if your camera sensor needed exactly 1 second to capture a scene at ISO 100, simply by switching to ISO 3200, you can capture the same scene at 1/30th of a second! That can mean a world of difference in photography, since it can help to avoid camera shake or motion blur.

Take a look at this picture:


       NIKON D700 @ 420mm, ISO 800, 1/2000, f/5.6

These Black Skimmers at 1/2000th of a second at ISO 800. So my camera sensor needed 1/2000th of a second to fully freeze the birds while they were in flight. Now what would have happened if I had ISO 100 on my camera instead? My sensor would have needed 8 times more time to capture the same scene, which is 1/250th of a second. At that speed, I would have introduced motion blur into my picture, because the birds were moving faster than that. In short, I would have ruined the picture.

2) When to Use Low ISO

As I have said above, you should always try to stick to the lowest ISO (base ISO) of your camera, which is typically ISO 100 or 200, whenever possible. When there is plenty of light, you should use the lowest ISO to retain the most amount of detail and to have the highest image quality. There are some cases where you might want to use low ISO in dim or dark environments – for example, if you have your camera mounted on a tripod or sitting on a flat, non-moving surface. In that case, bear in mind that your camera will most likely need more time to capture the scene and anything that is moving is probably going to look like a ghost:

3) When to Increase ISO

You should increase the ISO when there is not enough light for the camera to be able to quickly capture an image. Anytime I shoot indoors without a flash, I set my ISO to a higher number to be able to capture the moment without introducing blur to the image. Another case where you might want to increase ISO is when you need to get ultra-fast shots, like the bird picture I posted above. Before increasing the ISO though, you should first decide if it is OK for you to introduce some noise to the image. Remember, the bigger the ISO number, the more noise you will see in your images.

On many of the newer cameras, there is a setting for “Auto ISO“, which works great in low-light environments. The beauty of this setting, is that you can set maximum ISO to a certain limit, so when ISO is automatically increased based on the amount of ambient light, it does not cross the set limit. So, if I want to limit the amount of grain in my pictures, I typically set maximum ISO to something like 800 or 1600 on most entry-level cameras and I can push that number even higher on higher-end full-frame cameras.
