Focus Stacking ~ T+MGP 07
Depth of field is one of those fundamental skills that photographers learn. If you’re new to photography then the principle behind depth of field can be simplified to a choice of aperture. A small f number gives a smaller depth of field and a bigger f number gives a bigger depth of field.
But no matter what combination of focal length, aperture and sensor size used there will always be a limit to the depth of field that’s achievable. So if you want a truly massive depth of field then a single photo isn’t going to cut it. No, what you need is a series of photos of the same scene, all taken at different focal points. These can then be joined together using a technique known as focus stacking.
Focus stacking is a clever Photoshop trick which combines together the sharpest parts of a number of photos to create one image that has amazing depth of field. It’s quick, simple and if you have Photoshop CS4, CS5 or CS6 you can do it right now.
