Truth is there’s absolutely no effect except for smart sharpen and psd.
Here are my smart sharpen settings:
The action on the right is for smart sharpening all gif layers in one go as seen in this tutorial.
You can download my settings script here :) and follow the tutorial above with my smart sharpen settings (not the sharpen ones present in the tutorial)
This is how it should look after restarting photoshop.
I always apply action after loading files into stack but before making frames because it tends to mess up the order of layers.
The psd I used is actually a mix of PSD nr. 20 from here and this one with 2 curves layers before.
Curves layer is the same with Output 142 and Input 114.
The first one opacity and fill is 100% but the second one’s fill is only 50% with 100% opacity.
Sorry for late reply, hopefully it makes sense if not don’t be afraid to ask.
