Hello! I am an artist trying to create a certain effect that I can't seem to figure out on my own:
In a picture, I have areas in shadow and areas in light. I want the light parts to be the "real colors" (brown barrels, red apples, etc.), but in the shaded areas, I want it to be purple--perhaps a purple version of the "real" colors. Any thoughts? (Especially ones that aren't too technical?)

Hi Madeline!

There is a more or less "standard" way to do this. Sometimes it works "the easy way, first try", other times it takes some tweaking, but it's a good starting point.

Open your original image and duplicate of the base layer twice. (The "two rectangles" button in your layers dock.) You should end up with three layers, all alike.

Select the top layer, and apply the Threshold tool (Colors > Threshold), tweaking it as necessary to produce a black and white layer where your "shadow" is black and the rest is white (or as close as you can come).

Select the second layer, right click, and "Add Layer Mask." Accept the default properties for this.

Select the top layer (the one you reduced to black and white above), and do Control-C to copy it.

Select the mask on the second layer (just click on it), and do Control-V to paste the copied layer. Anchor the pasted layer (anchor icon at the bottom of your layers dock), and the pasted layer will replace the all white mask.

Delete the top layer, that you reduced to black and white above. It is no longer needed.

The layer mask is, in effect, a stencil. Where the mask is white, its parent layer is visible and its contents will replace the first layer in the finished image. Where the mask is black, the parent layer is transparent and its contents will not be present in the finished image. Remember to select the "image" part of the masked layer before applying filters, color adjustments, etc.; otherwise they will be applied to the mask itself.

Do whatever you want to the base layer, to change the appearance of the image where it is in shadow. Do likewise to the layer copy, to change the appearance of the image where it is more brightly lit.

Note that you can paint on the layer with black or white to subtract or add visibility; you can also fill selections with black or white to make parts of the 2nd layer vanish or reappear. You can apply a blur filter to soften the edges of the transition, or etc. - any effect you can apply to a black and white layer can be applied to a mask, to alter its effect on the parent layer's visibility.

There are a couple of "before and after" examples where I used this method, on this page, it is most visible in the "Real Estate Photos" one:

Hello,

I know, it's an ufraw-problem, but maybe anyone despite that can help:

since I installed gimp 2.7.x I can't open raw-files anymore. windows 7

Error message:
The program can't start because libgdk-win32-2.0-0.dell is missing. Reinstall ufraw to solve the problem

I reinstalled without success.

Any help is very appreciated.

Thank you! bettina

I have seen several posts related to your condition recently. A search of the recent archives will provide you a solution.

of course I was searching. but I couldn't find any entry with that problem.
but anyway, thank you for your hint.

The "jist" of the posts was that a *.dll file, probably the one you cited existed in two places and the wrong one was being found first. You might try (and I am relying on memory, old memory) searching for "ligqdk-win32*.dll" and renaming *one* and trying ufraw. If that does not work, change the name back to the original name and rename the other.

gud luk,

Thank you very much!

Just for those who might have similar problems:

I followed this advice:

http://registry.gimp.org/node/31

All the missing dll's were already present in the Gimp directories I had previously installed. I had to copy them from program files\gimp2\bin\xx.dll to program files\ufraw\bin\xx.dll

(from Pastingal)

and then reinstalled ufraw. now it works!

oh yeah!
