I have two images of a watch, with the watch placed in the same position, but the second-hand in two different positions. And I want to show up the same second-hand in two different positions in the final image. I mean can I do it without playing with the opacity sliders? Because I want to show up the second-hands very strongly in the final image.
File→Scripts→Load Files into Stack... or File→Scripts→Statistics... with auto-align, doesn't work in this case since Photoshop can't automatically align the the images as they are heavily paralleled.
