Hi guys, I wasn't sure where to put this picture, It was taken in Hannover Germany during my visit, it was sun set and the it was getting a bit darker. The RAW image came out pretty dark at iso100 75mm f/5.0 and 1/160 sec. The raw file contains no grain, after editing the picture it contains ALOT of grain. I fallow Serge Ramelli on youtube and tried of his post processing he did, however it doesn't look like his pictures are coming out grainy at all. Any help and critique would be very much appreciated.
Video I fallowed somewhat:
