I've took a look and photoshop has 2 blend modes, "linear burn" and "color burn", and I'm guessing if any of these blend modes are equivalent to the "burn" blend mode that there is in Gimp.

According to the GIMP Documentation about the burn mode ( http://docs.gimp.org/en/gimp-concepts-layer-modes.html )

"Burn mode inverts the pixel value of the lower layer, multiplies it by 256, divides that by one plus the pixel value of the upper layer, then inverts the result. It tends to make the image darker, somewhat similar to “Multiply” mode."

An according to the Adobe Photoshop help ( http://help.adobe.com/en_US/photoshop/cs/using/WSfd1234e1c4b69f30ea53e41001031ab64-77eba.html#WSfd1234e1c4b69f30ea53e41001031ab64-77e9a )

"Color Burn Looks at the color information in each channel and darkens the base color to reflect the blend color by increasing the contrast between the two. Blending with white produces no change."

"Linear Burn Looks at the color information in each channel and darkens the base color to reflect the blend color by decreasing the brightness. Blending with white produces no change."

I've done a little testing and it seems to me that "burn" gimp mode corresponds with the "color burn" in photoshop, but I'm not completely sure.

Hmm I took a look at the current git code and I discovered that the Gimp burn blend mode is already exported as "colour burn" photoshop blend mode, so this is not a problem anymore. I'm sorry maybe I precipitated myself a little bit answering this question.

Another question I have is if there are going to be more Gimp 2.8.X releases before , and if it will be, how often do they happen. I couldn't find any roadmap or similar in the wiki. I'm sorry I'm new and I'm don't know much about the gimp release process.

Thanks Guiu Rocafort
