Another neat preview of the Hoth Generator there! This thing's really coming together nicely now. Hopefully you're managing to cover all this 'behind-the-scenes' work for your 'extras' disc. Maybe some very rough 'time-lapse'-style shots-in-a-row of this stuff would look quite effective, to show how certain things progressed from start to finish?

And those screen comparisons are pretty interesting. On the blu-ray shot, it seems that the details on the rebels have been lost in a 'blur' compared to the original shot. When you look at the explosion on the bottom right of the frame, it's very apparent how 'blurry' some elements look in the blu-ray shot now.

Also, it's strange how the blu-ray shot seems to have the dead rebels lying in the foreground more 'in-focus' than the running rebels close to them, which are 'blurred'...yet in the original, both the dead and running rebels have the same amount of 'focus' to them!

I'm disappointed that the overdone 'digital scrubbing' of grain seems to be losing details in too many HD releases these days, and may have to change my title. The 'Blu, not Blur!' campaign starts here!
