I also went ahead and purchased the ACR video.
I do not have Photoshop (only Elements), so I do not have camera raw.
I'm hoping to learn more from this tutorial than from the Lightroom tutorial on the correct use of curves, historgrams, etc.
I've only looked at the first two videos and believe this was a good purchase.
I too like to support LL as well, but think this will increase my overall knowledge about RAW processing.
I'll second that!
