Let’s say I have 100 photos in a folder. On the first one, I would like to change the
-180, and save it. On the second one, I would like to change the
-170. On the third one, I would like to change the
-160, and so on.
Is there a way to batch process with a different value each time?
I’d probably use ImageMagick.
There is a feature available to modify the hue, but it’s percentage based instead of degrees.
Rotates the colors of the image, in a cyclic manner. To achieve this the Hue value given produces a ‘modulus addition’, rather than a multiplication.
However be warned that the hue is rotated using a percentage, and not by an angle.
convert rose: -modulate 100,100,0 mod_hue_0.gif convert rose: -modulate 100,100,33.3 mod_hue_33.gif convert rose: -modulate 100,100,66.6 mod_hue_66.gif convert rose: -modulate 100,100,100 mod_hue_100.gif convert rose: -modulate 100,100,133.3 mod_hue_133.gif convert rose: -modulate 100,100,166.6 mod_hue_166.gif convert rose: -modulate 100,100,200 mod_hue_200.gif
Most of the heavy lifting is done for you in that example, you would just need to create a script that indexes all the files in a directory and applies a sequential value given to the modulate argument.
