Find by Query: Black and White/Grayscale only

[JohnInCC]

Is it possible using the "Find by Query" tool to locate only images that are black and white or grayscale?  TIA.

Yes, try: tn.[colortype] = 1

This is not official (nor necessarily correct or complete), but colortypes seem to be:

1: Grayscale (either 8-bit or 16-bit) or B/W (1 bit)
2: 8-bit color
3: 24-bit color
4: 32-bit color
255: unknown color type

Your solution works.  Thank you very much,
John

Daan,

Thank you for this!  I used the '255' and found a few bad image files I was unaware of.  You are the smartest boy in class!

Cheers,
