We have two photoshop jobs to do.
One is putting a different head on a person in a picture. Must be done so size is exactly right and small details are corrected in background.Tones should be slightly adjusted too so it looks natural.
The second job is more tricky. We have a photograph of houses taken from above. The outline has been traced. So now we have a mono "line drawing".
We want to simplify that line drawing so this is sharp clear detail, but less detail.
We have a rough guide to follow.
We then want to have 3 versions of that treatment. A rough guide is provided to show what is wanted in the 3 versions.
