Author: Topic: Changing pixel colours

Hi all,

apologies for this question as i am sure it is simple, but, well, i don't know the answer...

How can i change the colour of certain pixels within a shot to make them darker/richer? Or is this at all possible?

I filmed a short piece with some young people (kids if you don't work with them) and managed to chroma key off a grey background i created by using the solarize filter (i can also sense jaws dropping at the stupidity of this, but i had no intention of trying chroma keying until this morning). Anyway, i have two clips side by side cropped down the middle, and on one clip this worked a treat, but on the other, a small area of the young persons face is the same shade as the now grey background, and so vanishes with the background. What i hope to be able to do, is to colour those pixels to change them away from the background colour.

Is this possible?

Many thanks in advance.
