When you're new to photography, one of the first things you'll probably want to do with your fancy, new camera is take one of those shallow depth of field portraits. This helpful video will show you three things that affect the depth of field in your photos.
Coming to you from Mark Wallace of Adorama TV, this great video will show you various ways to change your depth of field. Most people are aware that using a wide aperture can give you a shallow depth of field and that sought-after subject isolation for things like portraits, but using different focal lengths and your distance to the subject can also affect it, and these are things you'll want to take into account when shooting. For example, you'll have more difficulty getting your subject truly isolated when using wider lenses, and if you have the room for the increased working distance, you might want to switch to a more telephoto focal length if that's the look you're going for. Check out the video above for the full rundown.
