Digital BW, The Print

Hi!

Are there any ways to edit 16-bit grayscale or RGB-Pictures in 
Photoshop with 8-bit tools (burning/dodging, sharpening, but also the 
NIK color effects)? If not, are there any alternatives or plugins 
(especially for dodging and burning) that support 16-bit images?

Regards,

Peter

Personally I don't get on with the dodging and burning tools. Far too crude!
Instead I make feathered selections and then dodge and burn that area using the
curves tool. It gives me far more control, especially when there is need to
manipulate contrast locally. All this can be done in 16-bit.

Unsharp mask is available in 16-bit which is the best and only worthwhile
sharpening tool if you know how to use it properly - I personally think each
image is best served with individually tailored sharpening so I don't go in
for sharpening plugins etc.

Any intricate selections that need to be created using 8-bit tools or
filters (say a find edges with a gaussian blur for a selective sharpening of
an image) can then be applied to a 16-bit image by saving the selection to a
channel in the 8-bit image and then loading that selection from the 16-bit
image (after initially making a duplicate image of course).

If you are manipulating RGB images it is arguable whether 16-bit
manipulation is even needed so you might just want to stay in 8-bit after
any major tonal corrections. Certainly I find greyscale manipulations suffer
greatly in 8-bit but not colour.

The neatest tool for burning and dodging is the History Brush.
This works in both 8 and 16 bit.

Select  the History Brush
Select  the current state in the History Palette
Set the Blending Mode to Multiple for burning (i.e darkening)
Set the Blending Mode to Screen for dodging (i.e. lightening)
Use a large brush and a low opacity.

Hi Peter,

There is...or was...an excellent tutorial on editing 16-bit images on
www.computer-darkroom.com (Ian Lyon's site) called Editing 16-bit Images
in PS 6. I don't have or remember the exact link, but if you surf on over
you can probably find it. FWIW.

Best regards,
Alan Huntley

Tony,

I agree.  I do this the same way.

Disgraceful! I thought you were an image purist Austin - how dare you
manipulate nature's tones in defiance of the original scene <g>!

I am an image purist!  Just because someone else got them wrong along the
way, and I have to fix them, I find modifying curves (in only selective
areas as need be) to be a far more "pure" approach.

Roy,

the history brush doesn't work in 16-bit mode. When I apply your 
workflow a window pops up that says that the tool doesn't work in 16-
bit mode. Any other ideas?

Peter

Ok, forget it...I had the wrong brush. It works perfectly! Thanks a 
lot!

A shot rings out, as unable to bear the contorted rationalisations any

Did you forget to read the ";-)" after my post, Keith?

One way is to select an area with the lasso then run either levels or
curves on it. You can't use an adjustment layer
though.
