I have returned from my month-long honeymoon a few months ago, with thousands of photos to share with family and friends.
My camera is far from perfect so I tweak the photos I email to friends by adding brightness and contrast, and adding a bit of saturation out of hue, lightness and saturation.
I read the LXF135 Sept10 ImageMagick tutorial and it seemed like the answer to my prayers, since with mogrify, I could edit thousands of photos from my trip simply by using command line functionality.
The problem is that I just want to add 6 units (i don't know whether is percentage or anything else) of contrast to each photo (In Gimp, that would be Colours => Brightness-Contrast Option) and 6 units (i don't know whether is percentage or anything else) of Saturation out of Hue-Lightness-Saturation (In Gimp, that would be Colours => Hue-Saturation... Option).
The issue is that when looking at ImageMagick, I could not find an option to add contrast by the units I desired, and the option to add saturation is compared to the GIMP option of Colours => Colourise which yields a totally unintended result.
Would any kind soul out there know how to batch edit photos in the areas I have mentioned only?
Any google search points me back to ImageMagick and initial predicament.
Image editing is certainly not my area of expertise and solving this problem would save me hours of work.
Thanks in advance,
