Processing Techniques: Stacking

This sub-series explores how various processing techniques can be used to enhance images in different ways; this week's technique is stacking. There are 2 types of stacking. The first is focus stacking, where multiple images of a scene, set at different focus points, are stacked to produce an image with greater depth of field (ideal for macro photography). The second type is averaging stacking, where many shots of the same scene are stacked to average out image noise, effectively allowing photography at a higher ISO, with the cleanliness and detail of a lower ISO (ideal for astrophotography). Submit, in a single image, one of the frames used in the stack, and the final stacked image. Be creative and have fun.
