Any one know any free photo editing software.

I want to take picture of car dash board, and change colours on screen before i commit to what colour i want.

I tried downloading trial version of photoshop, but it gave me about 4 different things to download, so thought sod that.

I want to be able to edit this photo

Plenty of free photo editing programs HERE

Have a look for a program called GIMP, I've got photoshop my self and I'm pretty handy with it, what colours are you wanting??

I think there is just a bit to much red in pic, i just wanted to try different colours, to see which works best, or just to tone down the red as i think there is too much.

GIMP should be able to do that with ease,

It doesn't need editing, just deleting.

Why would that be then.
