screen or midtones?

I have some footage which is very very dark. I duplicated V1 to V2 and set it to SCREEN
Last footage I had also dark, I just increased the midtones....

before continuing this procedure, is there a reason not to duplicate V1 and set its mode to screen???

THanks

Don't know what you are talking about...I would try adding "Levels" to the layer and boost the gamma.

When life gives you dilemmas...make dilemmanade.

ankawa, I've mentioned this before and I'll need to again: You have got to take a lot more time writing up your posts. They're almost impossible to understand because of mangled syntax and missing words all over the place.

i'll read it, thanks

The "screen" compositing operation inverts the pixel values of the images, divides the lower layer pixel values by those in the upper layer, then inverts the values again. It's ? um ? kind of crap, really. It's a poor man's substitute for the traditional linear-light add operation.

Duplicating a shot and using a compositing operation is a very roundabout way of doing color correction. I would definitely not recommend it under any circumstances. And definitely not when using a hacky compositing mode intended for 8-bit image processing like "screen."

actually, using composite modes can really help footage that is too dark.

there was a long thread recently about underexposed footage,
composite modes came up there (i talked about them)
<[www.lafcpug.org];

screen and add mode can both boost levels WITHOUT introducing noise.
certainly they can do this better than simply lifting levels.

rather than deal with clips stacked up in layers,
i use the Too Much Too Soon diffusion filter.

like some other diffusion filters, this uses composite modes to get different looks.
i turn the AMOUNT (of Blur) down to ZERO, so there is no Blur effect at all,
and the Opacity up to 100%.

with these settings, the filter is effectively a "Composite Mode" selector filter,
with the added advantage that it has controls for targeting shadows or highlights, or everything.

very useful for underexposed footage.

it's not the end of the story, of course.
but it can get dark clips to a level where you can start using the 3-way Color Corrector.

I'm not sure about the not adding noise bit. Every time I try using the screen or add functions in FCP to brighten up badly lit shot, it always looks quite comparable to using the 3-way CC, with the same level of noise.

Thank You Nick, you saved my footage
