grade node?

[Anonymous]

there are many parameters in the grade. that is, lift, gain, multiply. what is the difference between them?

[christopher Fuston]

OK,

blackpoint – remaps whatever value you select to 0
whitepoint – remaps whatever value you select to 1

lift – remaps your new blackpoint to a new chosen value
gain – remaps your new whitepoint to a new chosen value

multiply, offset and gamma – are then used to apply color correction.

equivalent in shake would be

blackpoint/whitepoint = expand
lift/gain = compress
multiply/offset/gamma = multiply/add/gamma

but all in one node. so pretty sweet.

hope it helps
