I have a photo collection with 2000 photos (from phone). This is one collection, and I know that I can use "White-balance" (I don't know how to say in english, I used hungarian gimp... It is in layer/color/automatic menu: ) function on it. But very problematic to open every photo, and do it one-by-one.

Can I make a macro for this function?

Or can I use the plug-ins/*.exe for do this? How to I do it?

White-balance is the second submenu in the menu. First is "Balancing", and sixth is "Normalize".

If you install Dave Hodson's Batch Processor (http://members.ozemail.com.au/~hodsond/dbp.html), the AUTO LEVELS under the "Colours" tab will effectively perform an auto white balance.

Actually, it calls "gimp_levels_stretch", which I think is the function under the menu item "Stretch Contrast" (but I'm not sure).

Quoting David Hodson :

Looking at the source, it appears that "Auto->White Balance" calls "gimp_levels_stretch" while "Auto->Stretch Contrast" calls a plug-in called "c_astretch".

anyone will complie this plugin for win? already there is 1.1.3 version, if someone compile 1.1.7, I'll really appreciate 'cause I tried, but failed.
