Control your DOF

how to control you DOF ?

Before you know how to pick an aperture and control your DOF, it’s useful to know what aperture is and how it functions.

control your DOF

This is an illustration of your camera lens in various f-stops, or, more specifically, of this “diaphragm,” which is the mechanism which controls how much light reaches your camera’s detector. Think of this like your camera pupil.Think of this like your camera’s pupil. When you’re outside in bright sunshine, the pupil in your eye shrinks to a mere pinpoint, which keeps too much light from reaching your retina This is the reason why you are not blinded in bright sunshine, and it’s also the main reason why it hurts when you transition quickly from a darkened space to the bright outdoors – your attention requires some time to adapt to the shift in light. Likewise, once you’re in a darkened space your pupil gets bigger, allowing more light to attain your retina.

Your camera diaphragm functions in precisely the exact same manner: a wider aperture allows more light to reach the camera detector, just as a wider pupil allows more light to attain your retina. A smaller aperture lets less light to get to the camera sensor, just as a smaller pupil allows less light to attain your retina.

Now, photographer becomes confused with the whole number thing, and it’s easy to see why. F numbers appear at first to be backwards. F/22, by way of instance, is not a huge aperture, since the number might imply, however, a tiny one. Likewise, f/4 is not a little aperture, since the number might imply, however, a bigger one. One way to keep in mind this is to think as the denominators of fractions, which is that the way in which they’re written. 1/22, by way of instance, is a smaller amount than 1/4; therefore f/22 is smaller than f/4.

death of field DOF is control by selecting the right aperture only.
