I was just thinking the other day how cool it would be to have some photo editing software that would change the season, or time of day a photograph was taken.
So you would for example load in a photograph taken in the summer and then you could change the season to winter. It would adjust the lighting, put snow on flat surfaces, even change the cloths people where wearing in the photograph to make it look like winter.
Also if you took a photo and didn't like the time of day it was taken, it would figure out where the sun is and then change all the lighting and shadows to make it look like a different time of day.
I don't have the time or money to make this software, but if I patent it then maybe my grandkids can sue whoever makes it after I am dead.
