This is very clever.

I've used exported curves from photoshop to generate color correction LUTs, but actually just displaying the LUT in the screenshot, and then using the manipulated result to generate back a new LUT is much more flexible and pretty smart!

It’s a pretty common trick.

See e.g. section 24.2.3 here: http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter24...

From a glance the game looks remarkably like a Myst sequel (not that it's a bad thing by any measure).

Basically, yes.

>Blow said that he was inspired by Myst, but also by the non-existent games that could have been inspired by Myst but weren't...

>"It's like there's some really fucking awesome game like Myst that nobody ever made because it was filled with all of these illogical puzzles and stuff, right?"

>I didn't follow. He was inspired by an imaginary game?

By the way, I've been following The Witness blog for a while and they have some really amazing and surprisingly technical content.

Reminds me, in a way, of Super GameBoy palette-shifting--playing with the color-space of whole scenes, rather than individual objects, to achieve a certain area-theme.

I love color palette tricks like this. Reminds me a lot of the old color cycling tricks in 8-bit color games (http://www.effectgames.com/effect/article-Old_School_Color_C...).

Never thought of using this to redesign the color scheme of an in-game area without changing the original textures though - that's really clever.

This is a great idea. I always though that games underused 2d image processing techniques in their quest for visual beauty.

While a great feature, as Jon does mention, it's not novel invention. He cites NaughtyDog, but it has been use in many major games for quite a few years.

The nice part is that since it uses a 3D lookup table, it can do most LDR color correction that can be done in Photoshop.

This is so much cool.

I thought I'd just leave this here

Why not post on the original article? - he seems to be collecting links to other people who've done it before.

because I think it's silly to require email addresses to leave comments.
