[Gimp-user] Hue GUI
lo I've just seen this screenshot of a forthcoming new node in blender and i find this rainbow UI really nice because it lets you quite easily (gimp curve-like) modify any hue of the document. I let you check this : http://mke3.net/blender/devel/2.5/hue_correct_node.jpg or http://mke3.net/blender/devel/2.5/hue_correct_hue_val.jpg pygmee ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] changing colour
I have a test image which is monochromatic (black/white), is a grid pattern and shades from black on the left to white on the right which I have been using for some Unsharp Mask experiments. In order to extend these experiments I would like to change the test image to a coloured monochromatic image (red/white, green/white and blue/white). Is it possible to change this test image to a coloured image or will I have to hunt around to either find or make new images? Thank you for any useful advice.

In the Colors menu there are some useful tools to globally change the color, you should be able to do something with them. What immediately comes to my mind is gradient map, which maps the current gradient to the intensity levels in the image.

[Gimp-user] Sampling Toned Images
I was following a tutorial on Gimp Guru's I think it was, on copying tones from a sample image to your own. However, when I went to (Colors?/Map/Sample Colorize) and looked for the sample image in the drop down box, it wasn't there. I don't know how to get it into the drop down box for selection. Can anyone provide some help with this? Or maybe you might be able to instruct me in this whole procedure or direct me to another tutorial that can.

Hi Bryan, you have opened the sample image? If so, which GIMP version are you using? Works fine for me with GIMP 2.6.7 regards, peter Peter, thanks for reponding. I have the same version as you do. What I did was save a sample file from the site I was on to use in my learning. All I did was save it in the same directory as my own image but maybe I need to store that sample image in a specific location in order to access it for this purpose? -Bryan -- Bryan (via www.gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

You need to open both images in GIMP, both the sample image as well as the the image you want to colorize. The drop down boxes in question show a list of all opened images and the layers contained therein. regards, peter ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

I opened my image, then I opened the sample tone image. They are now in 2 separate image panes, so to speak. I positioned them side by side. Then in my own image I go to Colors/Map/Sample Colorize and a Sample Colorize view opens up. In that view I see on the left side is my original image described as the Destination Image. On the right side is what is described as the Sample Image but it shows my image in that one too. If I open up the drop down selector above the sample image, the only choices I have are My own image file name, or From Gradient, or From Reverse Gradient. How would I select the Sample Image which I opened as step two and is actually in a different window next to my original image? Sorry, I probably made this very confusing and I truly appreciate your patience for a rookie like me. -Bryan - - - - - - - - -- Bryan (via www.gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Please check the Image-Mode menu and make shure it is set to RGB. That's an ugly pitfall, because many operations only work on RGB images and GIF images are loaded as indexed color images (=256 color only). Same goes for grayscale images. regards, peter ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

The guy that made the tutorial offered these images with different tones that anyone could use. But they are png's and that isn't working. I tried just another raw file and when I did the Sample Colorize routine, in the sample section, my other raw file showed up like it should. So now I need to hunt down some sample files I can use. I wonder why he would have offered png files if they don't even work for the routine for which he was trying to teach. Maybe there is something I missed in there. -Bryan -- Bryan (via www.gimpusers.com) ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
[Gimp-user] Can I Subtract a color overall?
All - I don't know if this makes conceptual sense, but ... I am printing a scanned image onto a slightly toned surface (heavy watercolor paper), and I would like to precompensate somewhat for the effect of printing onto this warm toned medium. How can I correct the image before printing to approach the same colors as a print on white paper, at least in the darker areas? Thanks for any comments. - John Mills ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

How can I correct the image before printing to approach the same colors as a print on white paper, at least in the darker areas? I suggest trying this: 1. Create an image full of the color of the paper. 2. Look at the RGB values of the color you chose (my test color was 244, 242, 219) 3. Open up the 'Levels' tool. select Red channel, type the appropriate value (eg 244) in the rightmost field under the 'input levels' histogram+gradient. select green, type appropriate value (eg 242), select blue, type appropriate value (219), OK. 4. The canvas should now be completely white #FF / 255, 255, 255, and you should have an appropriate Levels preset stored to apply to your pictures; you may want to save the preset permanently with the '+' button next to the preset selector (after first selecting it) Note: This method will clip out detail of colors that are as bright or brighter than the real paper color. This is basically unavoidable according to your description of the problem.

But if you open the sample image you want to use, but which is not showing up properly, and from the main menu, select images and from the choices of the image menu select mode, in what mode--indexed, RGB, or grayscale--is the ~.png sample file? If it is NOT RGB, change the type so that it is RGB, and see what happens. ns ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user
