I would like to make this image to have 4:3 ratio, so it then later can be scaled up so it completely fits a 400mm x 300mm paper when printed.
It can not be cropped any more, so the size is 780x500, which is not 4:3.
As it needs to be scaled up when printed
- should I scale it down horizontally so I get 667*500 (remove pixels)
- should I scale it up vertically so I get 585*500 (add pixels)
