I’ve got a video and a photo shot in the same day and same place. But my camera (GoPro Hero 3, 720p) doesn’t allow to customise settings and video is very poor quality. I tried to fix this using curves but couldn’t achieve a good result. What approach should I use to make snow in the first picture to look like a snow in second one? I think if I will understand how to do this with one frame then I will be able to do it with a whole video. But take into account that it is considerably harder to make changes to a part of the video so it must be done with filters applied to a whole picture.
