Lightroom 4 post as I've recently purchased it.
As there are a couple of requests for both the shooting and post processing techniques, that's what I will start with, shooting techniques, then post processing. However, it will take me some time to prepare these two posts, especially the second one, so you might see some intermediate posts, but don't worry.
For some reason, Blogger is screwing up the images in old posts, I am still looking into it and will fix them ASAP.
I got a 5D Mark III, initial impressions will be up soon, then a full comprehensive comparison with the 5D Mark II will be done, a la 60D vs 550D post.
I will review the 650D since I got one for one of my friends and have used it a little, nothing new or radical apart from the focusing system and the touch screen.
