Aperture Priority and Depth of Field in Digital Photography

stop depth of field relationship quiz

Learn about how aperture and depth of field are used in photography and it is very handy to remember the general relationship between f-stop and shutter speed. tutorial, get out of your chair, grab your camera and take some photos! Quiz. Photography deals with capturing light in a way that appeals to your artistic sensibilities, whether you prefer perfectly-lit, tack-sharp portraits worthy of. Calculates camera depth of field and background blur and simulates it on a photo If the processing takes too long you can disable the Auto feature and run the.

The larger the F-stop — the slower the shutter speed will need to be. What you set your F-stop to can be limited by the amount of light that you are dealing with and the settings allowed by your lens.

In a low-light situation, you may have no choice but to open to the widest setting lowest F-stop. This will limit your creative options.

Which one do you like more, and why? The example above showed what your depth of field looks like on a close subject. How about when you are outside? In a landscape photo, your subjects are further away and so your depth of field will increase.

Landscape shot at f4 In the above image, I had to use a low f-stop as the light was so low. Still, with a setting of f4, most of the grain elevators are in focus, while the corn in the foreground is not. The smaller grain bins on the right are a little out of focus. The only thing that changed from the toy dinosaur was the distance from the camera to the subject. This is where you start flexing your creative muscles.

This is where you start making the choices that change your image from a snapshot to a photograph. This is where it starts to get fun. A few things about Aperture: Depth of field is defined as the area in front of and behind your subject that is in acceptable focus.

This is a consideration when you require sharpness above all else. In most lenses, this is in the mid-range. You will have to read reviews of your specific lens to find out what this is. For example, I use a Rokinon 14mm lens a lot. After reading reviews I found that f8 provided the sharpest images as well as giving almost limitless depth of field.

I use this setting on almost every photo I take with this lens. Depth of field is determined by the focal length of your lens.

This button will set the camera to the aperture you will be shooting at instead of at its widest aperture that is used for regular viewing. This allows to see exactly which objects will be in focus and which will not be.

The most commonly available values for each of the three settings are listed in the table below the list is not exhaustive, of course. Typical settings for aperture, shutter speed and ISO Stops: For instance, if you start with a single bulb and add another bulb, the light intensity will have increased by one stop. One stop represents the doubling or halving of light.

The Rule of Equivalent Exposure (With Quick Quiz)

Taking the example further, if you added two more bulbs i. But it has changed by two stops in total. I think you get it now. Likewise, light intensity can be changed when an exposure is made inside the camera. It can be accomplished by changing the aperture, shutter speed or the ISO.

Either of them increases the light recorded by the sensor by a stop thereby making the same exposure again. Adjacent values in each of the three tables are separated by a stop of light As you move up in each of the rows, you are increasing the exposure by one stop each time.

Similarly, by moving down, you are reducing the exposure by one stop each time. Take a look at how each setting is affected as you move up or down. Shutter Speed — As you move up the row by one step, you keep the sensor exposed to light for double the duration, effectively increasing the exposure by a stop. Likewise, by using the next faster shutter speed, the sensor remains exposed for half the amount of time thereby reducing the exposure by a stop.

ISO — As you move up the row by one step, you are making the sensor doubly sensitive towards light. That is to say, you are increasing the exposure by one stop. In the same way, by using the next lower ISO value, the sensor becomes half as sensitive to light as before, which means you have reduced the exposure by a stop. The Rule of Equivalent Exposure To be honest, now you can almost guess what this rule is. It tells you that you can obtain the same exposure at various different settings for aperture, shutter speed and ISO.

It is best explained with an example.
