exposure-blend : A GIMP plug-in for contrast blending 3 bracketed images. Download: The Problem Many typical photographic scenes contain far more dynamic range than modern digital cameras can record in a single exposure. Digital cameras are actually slightly worse in this respect than film cameras, since they are very unforgiving to the slightest over-exposure.
Beginning GIMP: From Novice to Professional ... by Akkana Peck A number of people have written to ask me for the images used in the book ... here they are, in the order in which they appear. The second edition images are here (please let me know if there's anything you want to see that I haven't put on the page).

:: Latest News Use G'MIC instead of GREYCstoration! GREYCstoration is not maintained anymore : We have developed a new plug-in for GIMP, called G'MIC (GREYC's Magic for Image Computing) .

The wavelet denoise plugin is a tool to reduce noise in each channel of an image separately. The default colour space to do denoising is YCbCr which has the advantage that chroma noise can be reduced without affecting image details. Denoising in CIELAB (L*a*b*) or RGB is available as an option. The user interface allows colour mode and preview channel selection. The denoising threshold can be set for each colour channel independently.
