Focus stacking for extended depth of field

Have you ever tried taking a close up photo of a beautiful flower using a telephoto lens and realized after focusing that most of the flower is still blurry due to depth of field?

It’s a challenge because you often need a wide open aperture in order to let enough light in to get the shot without too much noise but doing so also means a very shallow depth of field when what you really want is a large depth of field.

This doesn’t only apply to close up photos of flowers and such either. This technique can also be used in landscape…
