Is there a way to query a TIFF document and gather the names of the channels that are in an RGB document, that contains multiple additional channels. I have, for example, a document that has RGB, and 3-5 additional channels, and I want to query it with exiftools and poll the names of those other channels. I may have set them up with other names, over the course of time.
I'm not exactly sure what you are talking about. The TIFF ComponentsConfiguration specifies the Y, Cb, Cr, R, G and B channels. ExifTool extracts this, and any other standard information that exists (and converts them to more readable strings).

thank you for replying so quickly.
In looking up the values, with -list on a file I put together, it showed up under "Alpha Channels Names". Is that an event that can be queried separately to get the filename and these results?
And just so I actually know, are these known as "TIFF Tag ExtraSamples", or is that incorrect?
IFD Image
Code 338 (hex 0x0152)
Name ExtraSamples
LibTiff name TIFFTAG_EXTRASAMPLES
Type SHORT
Count N
Default None
AlphaChannelsNames is is a Photoshop tag (https://exiftool.org/TagNames/Photoshop.html), not a TIFF tag. I don't know if this is related to the TIFF ExtraSamples tags.

Thank you so much. I have learned more in the past few months working with exiftool, than I have in a cumulative few years in working with photoshop. The tool has also boosted me into the unix arena.
I am going to come back for more help soon. This is simply amazing that you have put this together.
