I would like to create an android app that would combine two photographs together to create something similar to what you would see in a double exposure photograph. Can you give me any ideas on how to do this?

推荐答案

要获得真正的双重曝光，您需要做的就是将R / G / B值相加每个像素都加上直线，每个分量的上限为255（至少为24bpp）。如果太亮，可以随时减少一些。

To get a true double-exposure, all you should need to do is add together the R/G/B values for each pixel with straight addition, with an upper limit of 255 for each component(for 24bpp at least). If it's too bright, you can always reduce it down some afterward.
