Adjusting exposure in Low / Mids / Highs only at DVinfo.net

Keith Malone · January 10th, 2009, 11:18 AM

In Vegas 8.0c and 8.1 does anybody know of a way to adjust exposure / gamma / brightness in the shadows, midtones and highlights SEPARATELY?

I've gone through all of the standard FX effects and can't seem to find a way.

Maybe there is a suitable plugin available?

Hope somebody can answer!

thanks
Keith

Edit the combined RGB channels in color curves - you'd add points to the graph.

Not the most straightforward method, maybe there's a better way.

Yep, had already tried messing around with the RGB channels. I was thinking that there has to be a proper and more accurate way?

Tried using Colour Correction?

Not being a smartalec, but that works well.
On opening there are three colour wheels. The left is for low tones, centre for midtones and right for high tones.

Use the eyedropper to the bottom left of each wheel to sample the colour you want to fix. Touch this on the affected vision, and it will come up with a suggested correction.

I'm still figuring my way around this, so be patient, but I have had some bloody tremendous results, matching skin tones from various clips and fixing unbalanced whites.. oh and gamma as well.

Cheers,
Ben

Keith, there is NOT much I can't correct with the SONY colour Corrector and the Colour Curves. They may not be the leading edge on colour work, but I find I can do most things? There's also levels too.

DO you have a BEFORE STILL sample to hand over to me? I'll do what I do and then send you back a veg?

Grazie

Thanks all for replying.

It's exposure that I'm actually trying to adjust in the highlights only as opposed to adjusting colour and hue. There is a gamma control in the Colour Corrector tool palette, but this seems to affect all lows / mids / highs as opposed to just say the highs. Any more ideas?

Exposure in the highlights, maybe use the levels and waveform then.
Have a look at this link.

For correcting exposures in shadows or highlights, I find the color curves the easiest way to do it. There are even some sample curves doing these things, that can be a good starting point, then you can create your own presets.

As long as you are using your scopes with it, this can be a very accurate correction method.

The YaVb blog has just published an article comparing various approaches to fix exposure problems:

1) use 3 instances of Secondary Color Corrector (shadow / mids / highlights)
2) turn off Hue/Saturation
3) adjust Luma high/low for each (add smoothing)
4) use Mask to set desired range

you could start with 0-63, 64-191, 192-255, add smoothing, then adjust
but using the mask would be an easier way for decide how the filter should be applied.

Newblue Color fixer (part of their essentials V package) has some wonderful controls, it's really simplified things for me. I still use Vegas CC on occasion, but not nearly as much.

Using Colour Corrector is a help although often you are, in effect, using it only to to re-establish White Balance. Levels and Colour Curves are also useful and I have also used NewBlue with good results but the best all round and easiest solution comes from Frederic Baumann's White Balance Correction and his Exposure Correction Plug Ins. Both of them are very easy to apply and respond quickly and also give the opportunity to do some fine tuning without difficulty. Really highly recommended - - you can download a trial for seven days to test them for yourself on your own problem material.
