I hope I'm on the correct StackExchange forum.
I have several equal images (17 at the moment). I want to blend/overlap all the images. So I can see a combination of all the air bubbles in total.
I've tried to place the images on top of each other while lowering the opacity in Photoshop. But this didn't work very well. Is there any tool, method or software which would allow me to achieve this?
