I have a series of pictures they have the same unicolor background. My goal is that on all pictures the background has almost the same color and brightness.
For that purpose I used color calibration module and created a preset after calibration with a color checker. I took a picture of Datacolor Spyder Checkr in the beginning and at the end of the shooting period.
I matched first the brightness of the background via color picker (L channel of Lab) and then I used the preset I stored from the picture of Datacolor Spyder Checkr. The white balance of the camera was not “auto”. I set “daylight” as WB in the camera for all pictures.
This procedure did not work well. There are still some color deviations of the background among pictures. The brightness plays also an important role.
Another possibility would be to copy and paste certain settings via history stack from one image to another. Actually, I need to transfer the RGB values and the brightness of the background picking them from one picture with well adapted background color to all other pictures.
I appreciate any suggestions to succeed this.
