Teal and Orange - Hollywood, Please Stop the Madness

March 14, 2010

Zack Snyder boldly went in a new far more horrible dimension. Apparently the entire movie makes it seem that the characters are in a fish bowl lit by purple and green lights. I only watched ~5m so far. I muted it and fast-forwarded to see how much more of this shit I'd have to watch before the palette changed to something sane. I figured I'd have to watch 5 more minutes tops. I figured wrongly. The whole thing? That's crazy.

I hoped this movie would be mindless fun. If I was lucky - it would be so bad it's good. I expect I'll watch ~10m and give up on it.

Color grading

Color grading is a post-production process common to filmmaking and video editing of altering the appearance of an image for presentation in different environments on different devices. Various attributes of an image such as contrast, color, saturation, detail, black level, and white balance may be enhanced whether for motion pictures, videos, or still images.

Color grading and color correction are often used synonymously as terms for this process and can include the generation of artistic color effects through creative blending and compositing of different layer masks of the source image. Color grading is generally now performed in a digital process either in a controlled environment such as a color suite, and is usually done in a dim or dark environment.

In Hollywood, O Brother, Where Art Thou? was the first film to be wholly digitally graded.

Edit 1

I started watching it again and I had to pause it after just a minute and take a screengrab. It's a far better example of the problem. I changed the image to that.

I grabbed this rip.
