Re: Keeping color, removing gradient :)

OK, I think I understand.

First save another version so you don't lose the original.

Here is what I would do, select blood layer #1 by, ctrl click on PC, or opt click on a mac...I think) first. Then shift, ctrl or opt click the blood layer #2. You now should have both layers as a selection. Next shift click each layer in the layer palette so they are all selected and go to the drop down menu at the top right of the layer palette and > merge layers. Now you have 1 layer with the blood as a selection while maintaining it's multiply overlay. Inverse your selection under select and delete and you should be left with one layer of the just he blood with no background and the look that you had with all of the previous layers. You may already know some of the above, but I wanted to make sure my response makes complete sense. Let me know if it doesn't. Also, I'm sure this isn't the ONLY way to do this, but it is how I would do it.
Hope it helps,
Tom
