I have just finished my forrest gum project, it doesn’t look the best but I tried.
First step I found a picture of a JFK speech, second I threw it into gimp by hitting file on the top of the screen and then hitting new making a horizon style white layer then adding a new layer to the white layer making it transparent then pasting the meeting on that layer using select on the hot bar. Secondly I duplicated my first picture by pressing right click on the layer and took a picture of myself and threw it into the picture of JFK’s meeting.
I then duplicated that picture into another layer and started on removing the background. to do this I went and hit colours and then hit deserter then turn to gray.
I then hit colours and hit invert to make things easier on me. After that I Outlined myself in black using the brush tool and then hi-lighted myself white.
