Can Epson V550/V600 software auto-detect half-frame 35mm negatives?

Question

I’m scanning 35mm negative strips shot on an Olympus PenD, so each roll has twice as many half-frame images. Manually selecting all 72 frames is very slow. Can the Epson V550/V600 software automatically detect half-frame frames, or is there a better workflow for scanning them efficiently?

It's probably not possible with the native scanner software, since it seems you didn't find an appropriate setting that does what you want. Some third-party scanner software, such as SilverFast or VueScan, might be able to do it. I haven't used either, so you will have to research them or try demo versions to see if they fit your needs.

If your scanner software is able to automatically detect full frames, you could write a script that uses ImageMagick to cut the results in half after capture. It wouldn't be fancy – no auto detection of image boundaries – but it would make further work with the images somewhat easier by splitting them into separate files. On Mac or Linux, it would look something like this:

for i in *.tif ; do
   convert "$i" -gravity left -crop 55%x100% "${i%.tif}-left.tif"
   convert "$i" -gravity right -crop 55%x100% "${i%.tif}-right.tif"
done
