I've tried it now, and I was right that those selection functions don't work on Image layers, either. So, as I suspect, you would need to Rasterize the layer (whether RAW or Image) before making the selection.
I'm not sure that's required, as I think there are other pixel selection functions that work on Image layers.
But even then, you cannot use the selections to do anything to the pixels unless you have a Pixel layer. So Rasterization would be needed as the next step even if you could make the selection.
Yes, that means that some functions require destructive operations. In the case of a RAW layer, you could duplicate the layer, and Rasterize the duplicate. Then make your selection and work with it using the duplicated (now Pixel) layer. If you need to go back into Develop, you can use the original RAW layer, and simply re-do the steps you took on the Rasterized layer.
Hi Dan C
Thank you very much for your rapid replay! It helps!
(1) so I hope for the next Update
(2) Yes, my fault!
I didnt know that presets are linked to the category and has to defined and used separatly for each category. Now it works!
In my opinion ist will be a good thing for future releases to have the possibility to combine the the presets and use it by one click
Suggestion: Even a new Preset "Last settings" (addition/option to "Standard") to use all the Presets of the last edit picture will be an helpfull progress.
Advantages: simple to use, no name to define, always available
Many Thanks
