you can just do "invert" from the image menu in Photoshop if that's what you use.

also, if you duplicate the layer, invert the duplicate and then set the blending mode to colour it doesn't look as poo.

'cept that wouldn't be legal in basic editing. all blending modes have to be "normal."

In CS3 you can use the curves feature which will let you adjust the picture to liking as well.

Image > Adjustments > Curves
Under presets go down to negitive
Now use the "input/output" graph box to adjust to liking.

... and any layers must be adjustment layers. No layers with pixels.

2 strikes, anything else you're do'in that's illegal in basic? ;o)

In Basic, you can't duplicate the Background layer, and you can't use blending modes other than "Normal."

Well I missed this some where. (The part about duplicating) This is what I have done in the past. I will duplicate the background layer so i can do the sharpening. The only reason why I do this is so I can click that layer on and off quickly to see the difference. Then I would flatten and save as a jpg. So this is illegal?

Edit: went to read. Because this is not an adjustment layer then, right?

Seriously, I had no clue. I'm someone who has learned photoshop as she goes. And I've learned it all here. So to think of something like this (where a duplicate layer IS NOT an adjustment layer) - I would never have caught it until I saw this thread.

If you have Photoshop Elements, open the "artwork and effects" toolbar, select "layer styles", select "photographic effects" and click on "negative." I have no idea how to do it in full version PS or CS3.

This is technically illegal (but generally overlooked) because the top (duplicated) layer is at 100% opacity, and therefore completely replaces the background layer.

Where the process becomes completely illegal is when you blend the two pixel-containing layers, either by reducing the opacity to less than 100%, or by setting the Blending Mode to other than "Normal" -- it was in "Color" mode in the example cited earlier.
