Past days update progression in work development

Today I did some research on how to do photoshop to crop a picture fast and clean way.

I learned this in order to cut out the hair of our character from greenscreen. 

Some of my research done here are based on how to do cut out hair and the character from green screen fast and easy. I did some try outs on these and it did not turn out well as they not not suite what we needed.
