Sometimes no matter how far you stop the lens down it just isn't optically possible to get sharp images throughout in a single shot. Sometimes you might be able to pull it off by stopping the lens down far enough but the resulting long exposure times could lead to blurred images from subject movement. But it can also be used for landscape work where you need just a bit more depth of field than seems doable in a single shot. The technique is often associated with macro photography where the magnification employed brings with it very shallow depth of field. Focus stacking is a technique that uses software to combine multiple shots taken at different focus distances to form a composite result with greater depth of field. Whatever depth of field you capture is all there is in that photograph. Your eyes automatically adjust focus when you look at a scene but not when you look at a photograph of that scene. ![]() Here are two good solutions to make your shooting easier. ![]() The higher the magnification, the shallower the depth of field and the more shots you need to get the results you really hope for.
