Generative Fill and Grayscale

[JR Boulay]

Hello,

Rather than receiving a message asking me to convert the Grayscale image to RGB, Lab or CMYK before using Generative Fill, I would prefer the mode change to be automatic and for the message to tell me that my image has just been converted to RGB and that I am free to convert it to another colour mode.

Thank you.

To the Photoshop Team,

For the record, I vote against this idea. Please don't ever let Photoshop convert my images to another color mode for me.

If you implement this, let it be a choice that we can disable.

Thank you,

Jane

"Please don't ever let Photoshop convert my images to another color mode for me."

If you want to use Generative fill you must convert to another color mode, so it should be automatic.

In any case you can Undo/Revert/Save As.

I'm with Jane. I vote nay.

Not that I ever use generative ai toys...eh, tools, so it doesn't affect me 😉

Playing devil's advocate... It should be easy enough for the devs to add a confirm prompt to OK before the mode conversion for safety. They could also add a "don't ask again" checkbox so that this becomes seamless.

There's probably a good reason that this "obvious feature" doesn't exist.

For what it's worth, the following script will conditionally convert a grayscale document to RGB and then bring up the generative fill command (again, a confirm dialog could be added, which would be counter intuitive, as this is the feature request so why put in a road block):
