Whitening Teeth

I wrote down a way to whiten teeth (after selecting them) a while back and now can't find the paper I wrote it on.

Anyone wish to re-explain how this is done to me - again. In photoshop.

While I'm sure there are better methods, you might try desaturating the yellow channel a bit and then slightly lightening the composite RGB via Hue/Sat (Cmd-U).

on your selected teeth
go to
selective color
white and reduce the colors as needed

After selecting the teeth...(crawling ants all around the teeth)
Press Command J (Control J on PC)
this creates a new layer of just the teeth,
now press Command U (Control U on PC)
the Hue/Saturation box appears...

Set:
Saturation (minus) 10
Lightness (plus) 4 to 10

Now you have the whitened teeth on its own layer !
As it should be.

This is more in line with what I recall - thanks....

I use this method for all kinds of changes because it is quick, simple and very precise.

1. Click on the ajustment layer icon on the bottom of the layers pallet.
2. Select levels or curves
3. This creates an ajustment layer.
4. Make your adjustment to this layer paying attention only to the teeth.
5. Click ok then hit control I to inverse the image.

6. Now simply paint the teeth with white and adjust opacity to taste. If you mess up just paint back with black. You can also smudge, clone or do anything else you want to the image.

7. This method works equally well for other ajustment layers such as color balance, Hue/Saturation, etc.

i just use the dodge tool and set the brush to midtones to the desired size and the exposure low and carefully whiten the teeth till they look clean but natural. i do the same for the whites of eyes. very easy and quick

I assume you mean to invert the mask on this new layer and then paint with a white brush with the mask active.

The beauty of this method is that you can also use it to dodge (dodge effect, not actual dodging) other areas, like the whites of the eyes or highlights in the hair, wherever you need special brightening. I think there may be a bit more noise introduced with the actual dodge and burn tools, as I recollect from experience. This method also can preserve dark areas if the new layer is contrasty as well as brighter. Works for everything, as was mentioned (color, saturation, etc.), a layer for each if you want to get specific on your touch-up. The layer can also be reduced in opacity, obviously.
