fill or opacity with Color Lookup?

[anderson234]

Hi,
In some tutorials, after adding Color Lookup layer, they lowered "fill" instead of "opacity". Why? there're no such thing like text in this layer.

Thanks.

And this is why I tell it like it is...

Fill affects numbers before they are calculated (I'm talking color values).

Opacity affects numbers after they are calculated.

In most cases it makes no difference, but obviously it does to them.

Thanks for fast response. A little confused here: so which is better, before or after calculation ?

There is no better, it does different things, and the difference based on the blending mode rather than the layer.

I still haven't got into the whole "3D LUT" thing, as I am yet to see it replace particular layers affecting particular things, but once it's properly integrated into PS, I might give it a whirl.
