So recently I tried comparing both the night and normal photo modes. if you check the above images you will be able to find the difference between the two. Please dont mind the photography as I shot them just to compare. personally I liked the night mode a lot and it can create really good images with nice details and less noise. This were the pros and only con is it can be improved. I am sure Samsung is working on it.
Let me know your reviews of the same and make some good discussions regarding the same.
