i’ve been spending way too much time on a recent project. i’m stuck at the point where i play floating point imagery back to the screen and the chroma is eating my nice clipped luminance values. most likely this is clear as mud to you. me too. i need to read this thing. maybe it’ll help me finger it out.

[edit 2007.12.19] Turns out that it is helpful to think of HSB colorspace as a sphere instead of a cylinder. As B approaches white or black, S should approach 0. Works like a charm.

[edit 2008.03.24] Here is the Wikipedia entry for HSL/HSV colorspace. Includes some useful math for RGB to HSL and back.

[edit 2008.03.26] Scroll down on this page to get to their description of HSV2. This thinking may apply to my float lightness gain problem.

And then there’s Charles Poynton, who has done a lot of thinking about color.

We also have couleur.org, by Philippe COLANTONI, with short explanations and 3D graphs of several color spaces.

Dinner: take-away Chinese on the back veranda in shirtsleeves. Darkening sky. Conversation. Orion’s headstand above. Nice.

Every now and again I read a spam. Very rarely are they as poetic as this one. I suppose it’s an electronic version of the classic 1000 monkeys + 1000 typewriters situation. I wonder how many truly brilliant poems my spam filter has destroyed?

f#@*ing off at work
the afternoon ticks away
in office murmurs

I tell you, this pneumonia stuff is serious. Instantly I’m an old man — walking slow, using the escalator instead of the stairs and no riding the bike.

Stuff happens slowly. I’m finiding myself actually enjoying the new pace. Leaves more time for looking and thinking.
