I want to find a TIF image inside a directory with a specific color depth (8 Bit) with 10'000 images. It does not need a GUI, a basic log file would be sufficient. It should run on Windows and available for free. I can think of some batch or powershell related solutions.
This does not need powershell or anything. Goto folder and select Detail view on the column heading right click and select more.
Select Bit Depth and click OK. The bit-depth field will now appear. Click on the column heading bit-depth and you can sort it ascending or descending there by grouping the same ones together.
Goto windows search on the folder in question and type: bitdepth:8 and hit Enter
