Photoshop - How do i use the history brush?

January 18th, 2010
Hi i've just got photoshop on my pc as this seems to be the best programme for a lot of things

One of the things i really want to do with it is have a black and white background with certain objects in colour i have been told this can be done by changing the photo to black and white and then painting the colour back in with the history brush but i can't work out how to do it

Can anyone explain how to do this please?

Thanks :o)

Unfortunatly i have no idea what so ever how to use photoshop so i can't get it to work if i have two layers and change one to b&w it also changes the other layer to b&w.... i don't know how to use masks....... and the hsitroy brush just keeps telling me i can't do what i want to!

I'm afraid i'm totally new to this so need it in very simple terms lol

to make one layer black and white, go to Image>Adjustmenst>Desaturate. After that it will look a little flat and dull so go to Image>Adjustments>Levels (not auto levels) then slide the 3 little triangles around to make it have more contrast, this is subjective do what looks right to you.

To make a mask is a bit hard to explain here, so try this video.... http://www.metacafe.com/watch/1358284/photoshop_cs3_tutorial_masking/

For the history brush you need to convert your image to black and white, open up your History Pallet (Window>History) then on the left side you see boxes, you will see something like "Open" then "Desaturate" click the box on the left side of open. What this is doing is, your telling your history brush to bring back what the picture looked like at this point in editing process. This is not the right way to do this cause if you mess up its harder to fix. What this is really used for is, if you made 30 different adjustments to your picture but didn't realize something in the back ground got messed up back at step 10 and you don't want to have to redo the other 20 adjustments, you would select step 10 to be your history brush, use your history brush to clean up that select area and the rest of your photo remains edited to your liking and you don't have to redo all 20 steps again, sorry this is long winded, again this is kinda hard to explain online.

The proper way to do just about any editing is with layers and masks, once you get the hang of them, there isn't anything you can't do in photoshop. Hope this helps.

better yet, this will explain it better then I can and why you shouldn't use it to make big changes in your document but rather as little fixes. It also includes pictures to help.
