I try to get “Lab values” from Image.
I think there is two way to get “Lab values”
The first one does Image > Type > Lab Stack, the second one does Color > RGB to CIELAB
What is the difference between the two?
The images and measurement results for each channel (Lab) are different.
Sample image and/or code
I downlode this picture from here
RGB to CIE LAB ver
Lab Stack ver
Each picture in each channel is not the same, Why is this so?
