Okay so this pack, contains 500s of Lightroom presets and they are from various creators so i cant really put much info here but they are useful, obviously and probably will light up your lightroom as well :p
if theres no file extension like .zip or .rar then dont worry just right click on it and click decompress it will work. 7-zip is recommended. it always works fine. above links dead? use these mirrors below! also includes zippyshare + openload links!
