I would like to use GIMP 2.10 to compare to the results I got with ImageJ 2.0. The LAB given by GIMP 2.10 is supposed to be Hunter Lab color space or CIE L ab* (1979) color space ? ImageJ 2.0 uses 16-bits and 32-bits, so no problem of posterization if I understand well. I am using ImageJ 2.0, do you know if in this version of ImageJ the gamma correction is applied ? I read on the website that many softwares (including ImageJ 1.40) produce gamma error in picture scaling. Then, I use the plugin of ImageJ 2.0 “Conversions between RGB color space and Lab color space” (Plugins / Image / Color / Convert RGB image to Lab Stack v1.00)įinally, Analyze / Histogram / Copy and then I paste the values in a spreadsheet which allows me to compute the mean, the standard deviation, etc…

Could you please advise me another free software that does well the conversion ? I am not sure that the ICC profile given to the photo by XnConvert is sRGB and that the gamma correction is applied.

Then, I upload the photos of my computer, and convert them from CR2 (RAW format of Canon) to Tiff with the software XnConvert. I take photos in sRGB color space, but could you please tell me if you think I should use Adobe RGB instead ? A SLR Canon camera is placed on top of the box and takes a photograph through a hole. My lab owns a box with constant lighting in which I can put at once my product.

With this values, I will then be able to make a statistical study of the distribution of the colors. I am a French PhD student currently struggling with colorimetry, and especially converting from RGB to Lab.ġ°) to take a sRGB photo as close as possible to the real colorsĢ°) to decompose my sRGB photo in mathematically right values of L*, a* and b*ģ°) to get the values of L*, a* and b* for every pixel (2 columns of data: the value of L* and the number of pixel corresponding to this value - the same for a* and b*)
