I needed to convert the color profile of my image from ProPhoto RGG to Adobe RGB. However doing so flattened my image - or appeared to. Why is this?

Thanks.

When you convert the profile of a multilayered document you are normally given the option to flatten it, as not doing so can change the appearance of some layers and the way blend modes work together. If you did not get that warning dialogue then try resetting the dialogues using Edit > Preferences > General > Reset All Warning Dialogues.

And not just blend modes, adjustment layers too. They would change meaning in the new color space.

If you want to preserve the current appearance of the image, you have to flatten. If you don't, you'll need to redo your adjustment layers and set new values.

Here's a crop from an Adobe RGB file with two simple adjustment layers (curves and color balance) - converted to ProPhoto without flattening:

@Barton5C39 as @D Fosse wrote " If you want to preserve the current appearance of the image, you have to flatten. If you don't, you'll need to redo your adjustment layers and set new values."

That’s absolutely right, it's bad practice to convert between colour spaces or colour models (e.g. RGB>CMYK) without flattening . I'd recommend leaving the change until later so you can archive the Prophoto latered file and convert to Adobe RGB for whatever reason.

Why are you doing that, by the way? It might help us guide you in workflow to know what you're making that conversion.

I hope this helps

Thank you - I had made a copy of the image before doing the conversion so as to preserve the ProPhoto RGB file. The reason I am converting is because I am in a group exhibit later this summer, and the gallery wants the images in Adobe RGB color space.
