Dynamic 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 set the depth of field exactly for each situation? V 3.0: Lens flares & dirt, visor reflections / water droplets, god rays, depth of field, night & thermal vision scopes, dynamic wet surfaces with reflections, rainbows, volumetric light & fog, colored speculars and many other effects. Depth of field also appears shallower for SLR cameras than for compact digital cameras, because SLR cameras require a longer focal length to achieve the same field of view (see the tutorial on digital camera sensor sizes for more on this topic).
What is Depth of FieldBelieve me, understanding what depth of field actually is is a whole lot easier than explaining what it is. I'll take a stab at it without relying on Wikipedia or some official definition. Here we go:Depth of field is essentially the distance between the nearest in-focus area and the furthest in-focus area in your shot. When that distance is short/narrow/small, it is known as 'shallow depth of field' and your foreground (everything in front of your main subject) and background (everything behind your main subject) appears out of focus, while your main subject appears in focus. When that distance is long/wide/large, it is known as 'deep depth of field' and your foreground, mid, and background appear in focus.Credit:Factors that Affect Depth of FieldOnce you decide on what kind of depth of field you want to achieve, you'll need to know how to achieve it. Don't worry, newbies, it's really not very complicated.
But before we dig into the three main factors at play, understand that each of these factors have affects beyond depth of field, and adjusting them might result in changes to your exposure, angle of view, and other things.ApertureFirst of all, what the hell is aperture? Well, it's the opening of your lens' diaphragm and it's where light passes through into your camera body until it eventually reaches the camera's sensor.

(Then magic happens and stuff and an image appears.)Now, make sure to absorb this little piece of information into your brain because it's weird: the size of the opening is represented in a value called an 'f-stop'; the smaller the opening, the larger the f-stop, the larger the opening, the smaller the f-stop.The larger the f-stop, the deeper your depth of field is going to be.
