I also received the promo code.
My question is, is Lightroom 6 coming out soon?
BTW, I never used Lightroom previously. I use Canon DPP to do some minor processing.
Never used DPP, but Lightroom is great. So easy to edit pics. Upload 1000 pics at once or more if you want.
If you make a change in one pic and all pics need the same adjustment you can sinc it into everyone in seconds.
There are 100's of youtube videos to assist with it's use.
