These all looked terrible for me until I downloaded the jpg and viewed it in gimp or photoshop. Does screenshot comparison do some funky stuff when viewing it through the browser? I mean if you look at that snap of luke sitting in the cantina and then download the picture and view it does it look different to anybody else? Perhaps chrome is the culprit, I’m not sure. I just thought I’d throw it out there that downloading the jpg seems to produce better results for me.
BTW, glad to see people tinkering with the laserdisc releases!
