Focus-stacked images are great but can take up to several minutes to shoot all the images. This doesn’t work well if flowers or animals are part of the scene, since they move. One way that does get all the images in one or two seconds is to shoot a brief video while pulling the focus, convert the video file into all the individual images needed, and stack those. It works well for small images.
Andy Fraser has written up a test with more details and posted it to the “Techniques and Tools” folder in the Documents part of the RAPC website. You must be logged in to access the file. The file is named “Quick Focus-Stacked Images from Video File.pdf”.
