LR4 DNG Lossy Compression

Anyone give this a try?
I was messing around with it and it is extremely impressive. 50-70% reduction in file size yet I can't even see a difference, even at 1:1. I don't think I will use it across the board, but for 3 star and fewer images, I am considering rolling it out on all of them.

These used Lossy compression before exporting 100% JPG. I can't even tell the difference.

Even quickly flipping back and forth in LR with the DNG at 1:1, there is absolutely no difference.

Definitely worth a look, especially for people who keep everything. You can also reduce the number of pixels, which I guess makes it less than full raw but still keep many of the raw properties.

My plan was to use it for 3 star images and lower, but I'm considering just doing it across the board. I honestly can't even see a difference. Since I use LR, it only converts it once so you don't have to worry about repeating JPG compression issues.

Came across this comparison on twitter & I guessed wrong

Whahahaha. Didn't know that

Since I tend to keep too much I decided to use it. So far no problems or discernible difference.
