How to export a 4-band TIFF from Photoshop for ArcMap?”

Hello Adobe Team,

I work with satellite images in RGB format, where each channel represents a different spectral band (e.g., Band 3, 2, 1). I use Photoshop's Generative Fill to fix visual distortions in the image.

After editing, I need to export the result in a way that ArcMap can read it as a 4-band TIFF file — not just RGB, but with an actual 4th band added (e.g., a cleaned version of Band 4).

Is there a way to do this inside Photoshop? Or export a TIFF from Photoshop that supports more than 3 bands?

If not, are there recommended workflows that combine Photoshop and GIS software to achieve this?

Thank you!
