I am trying to find a more automated method of selection from 1000s of files. The camera takes (and saves) 8 focused stacked photographs then constructs a composite image which is named next in the sequence. I am taking a time lapse sequence of ca 200 images. I want to choose only those 200 composites, i.e. every 9th file.
This can be achieved by renaming every 9th file by, say, adding a C as the first character. I could then sort on C*, then copying and manipulating them further.
Is there a method of doing this? I am a novice in BNU, but a scan of the options does not look likely.
