As you may know, Delaboratory is a “color correction utility”, inspired by Gimp and RawTherapee.
The latest version available is Delaboratory 0.8, which brings the following:
- floating point precision (not 8-bit like Gimp, not 16-bit like most raw processors)
- native support for multiple colorspaces (sRGB, ProPhoto RGB, LAB, CMYK, LCH, HSL, HSV, BW)
- non destructive editing (adjustment layers)
- KISS design
- realtime preview
- basic operations: CMYK curves, CMYK levels, RGB curves, RGB levels, white balance in LAB, saturation in LAB, LAB curves, BW curve, HSV equalizer, LCH equalizer, recover
- shadows/highlights, vignette, local contrast, LAB/BW/RGB/CMYK gradients
- expert operations: levels, curves, equalizer, exposure, saturation, white balance, fill, tone, local contrast, auto_dodge/auto_burn, sharpen, vignette, gradient, gaussian blur, recover
- highlights, recover shadows, channel mixer, high pass, c2g, copy
- RAW support via dcraw
- up to 5 color samplers
- histograms and color matrices
- many blend modes (multiply, screen, overlay, inverted overlay, dodge, burn, add, grain
- extract, grain merge, sub, difference, darken, lighten), color/luminocity blending for RGB and CMYK
