I am inquiring about an advanced technique using GIMP I am an old fashioned "silver" photographer who has made highlight masks when the highlights were blown out for Dye Transfer. I can't figure out how to do it with GIMP although there is evidence that it can be done. This URL below is an example of a photograph I made that shows a ceramic cat in the foreground whose highlights are still there if the image is printed too dark. The photograph was shot in raw mode and Adobe colorspace. http://home.roadrunner.com/~cashmere/_MG_0667a.JPEG Here is an example I found to correct such a problem. The information is so dated that these example menus are extinct and I can not find any such menus. http://www.gimp.org/tutorials/Blown_Out_Highlights/ I can duplicate the image with a ctrl-D and using the duplicated image. I did- color->threshold and enter 240 so that the range is 240-255. Now I have the highlights I wish to darken as a negative image. My problem is how to combine the images in such a way as to "burn in" the highlights and recover the lost detail. This image could also use a shadow mask to improve shadow detail, but that's another problem - one problem at a time. How do I combine the images in the manner I have described above. Any help would be greatly appreciated. I am using GIMP 2.8.10 - OpenSuSE 12.3 Jack _______________________________________________ gimp-docs-list mailing list gimp-docs-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gimp-docs-list
