    • The area within the depth of field appears sharp, while the areas in front of and beyond the depth of field appear blurry., can also render 3D models with shallow depth of field for the same effect., depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. Although a can precisely focus at only one distance at a time, the decrease in sharpness is gradual on each side of the focused distance, so that within the DOF, the unsharpness is imperceptible under normal viewing conditions.In some cases, it may be desirable to have the entire image sharp, and a large DOF is appropriate. In other cases, a small DOF may be more effective, emphasizing the subject while de-emphasizing the foreground and background.

    • Notes on DoF and FoV - www.similaar.com, I've come to realize that what depth of field really depends on is field of view, sensor size and lens aperture: lens lenght and distance to subject don't matter, as long as the field of view, defined as "height and width of image at focus distance", remains constant. Let's see an example. Suppose I want to take a head-and-shoulders shot of some friend. He's going to be in focus, and picture height at that distance has to be around 64cm (2 feet). Besides that, I want my friend to be in focus, over a very-out-of-focus background. I want my depth of field to be around 22cm (9 inches). My camera is a 1.6x-crop canon, my target aspect ratio is 1.77:1 (16:9), and I have access to any lens I want to use (lucky hypothetical-me). What I've found is this: no matter which lens I use, in this example I want to set aperture to f/2.8.


    • In this section we’re going to discuss several crucial elements for exercising greater creative control over your final photographic image. Other than lighting, composition and focus (which includes depth of field) are the main elements that you can exercise complete command over. Focus enables you to isolate a subject and specifically draw the viewer’s eye to exactly where you want it. The first thing to understand about focus is depth of field.Depth of Field (DOF) is the front-to-back zone of a photograph in which the image is razor sharp. As soon as an object (person, thing) falls out of this range, it begins to lose focus at an accelerating degree the farther out of the zone it falls; e.g.
