My point and shoot camera can't do long exposures (at least not during daylight, there is a fireworks setting for nighttime). I wanted to try to create smooth flowing water using a technique I had read about where many single photos were blended. I realize it won't be as good as a long exposure but it'll do for now.
However, I'm unclear on the blending settings of multiple layers. I seem to recall having read that the settings are based on #layers/100% so, for a simple example, if there are 3 layers, then 3/100% = 33% so the top layer is 33%, the second layer is 66% and the bottom layer is 100%.
No, the rule is that layer opacity is 100%/n, where "n" is its order in the stack (starting with 1 for the bottom layer). So that's 100, 50, 33, 25, 17, 13, 11, 10.
If you have many layers, make sure you have only that image opened in Gimp, open the Python console (Filters>Python-fu>Console) and enter these two lines exactly:
- - - - - - - -
image=gimp.image_list()[0]
for i,l in enumerate(reversed(image.layers),1): l.opacity=100./i;
- - - - - - - -
(strike enter twice after the second one)
