Adobe After Effects 7.0

...has been announced.

Ten great things you can do with After Effects 7.0:

1. Dump eLin and work in linear 32-bit floating point
2. See an accurate preview of how your film work will look when projected
3. “Make Your Video Look Like Film”
4. Take advantage of linear-light layer blending, even in 8-bit
5. Color Manage your workflow
6. Apply 8- and 16-bit effects to 32-bit images

sRGB

The sRGB luminance curve is designed to be an approximation of a gamma 2.2 curve, but with a straightline portion near zero to avoid rounding errors in conversions.

Duh.

It's hard to find good online resources with the to- and from-sRGB conversions expressed in language compatible with nerdy compositing applications, so I thought I’d consolidate some findings here.

Spitzak has the sRGB to linear conversion right:

x < .04045 ? x/12.92 : pow((x+.055)/1.055, 2.4)

And here’s its inverse:

x < .0031308 ? x*12.92 : (1.055*pow(x,1/2.4)) -0.055

The question mark is an if/then. If the conditional before it is true, do what’s before the colon. If false, do what’s after.

Boom.
