Applying same filter to multiple layers is possible in Photoshop but for us non-Photoshop users, is there any other option available ? Gimp has a GAP plugin, but Gimp doesn't work on my Windows10-64bit machine.
If there are any other alternatives to achieve this operation?
There is a way to do it in GIMP without any scripts, or GAP. It's a little more manual but only requires two keyboard shortcuts, so it's pretty fast. A script could even probably be written to automate it, but I have no idea how to do that. Anyway, here's the keyboard shortuct method:
Choose the top layer, and apply any filter
Press ↓ (the down arrow key) to select the next layer down
CTRL+F applies the last filter used
Repeat steps 2 and 3 until finished.
Obviously, this may be a little tedious if you have hundreds of layers.
Affinity Photo allows you to select several layers at the same time and apply the same filtering to all selected layers
In Krita you can define filtering with Krita's own filters to happen as "filtering mask" which is effectively like Photoshop's layer style except it works with different set of filterings. To apply the same filtering to another layer you must Ctrl+Drag the filtering mask on the wanted layer in layers panel.
Add-on filters, I mean G'MIC collection, do not know filtering masks, but you can apply last G'MIC filter to another layer simply changing the active layer and clicking Filter > Re-Apply last G'MIC Filter.
Finally there's some on-line image editors. At least Photopea allows one to select several raster layers and filter them all with one command.
