We then shoot two photos, one with each lens but both using an f/8 aperture. When you examine the photos, the one shot with the 200mm lens would appear to have less depth of field than the one shot using the 20mm lens. If you want to produce a shallow depth of field effect, use a longer focal length. Aperture. As I said earlier, the most common way to change your depth of field is to change your aperture. When you lower the f-stop (f1.4 f2 f3,5) you widen the aperture or iris of the lens. This allows more light into the camera and reduces the depth of field making less of the image, around the focus point, in sharp focus. A way of creating this feeling is by faking depth of field. Now, this is not a hard process; it is actually fairly simple. The easiest way to create depth is by blurring the background and the Note the F-Stop field: I’m not sure what it’s used for, but it doesn’t set the actual F-Stop of the depth of field effect. It doesn’t matter what you add here for the effect to render. Speaking of rendering: if you press F12 now to do a quick render, you’ll be disappointed to see that no depth of field effect is being produced. There's a range of ways to control the depth of field - the choice of aperture, focus distance and the type of camera. In a nutshell, wider apertures and closer focusing distances lead to a There are four main factors that control depth of field: lens aperture, lens focal length, subject distance, and sensor size. Your sensor is pretty well set, so you won’t have much luck changing that. Your focal length and distance to the subject are usually determined by your choice of composition. So the lens aperture is your primary .
