1. Re: Where is Histogram in Three-way Color Corrector
Bill Hunt Jan 2, 2011 11:42 AM (in response to Sengstack)Are you on a PC, or the Mac?
I seem to recall that with certain Effects on the Mac, Histograms were not available, but do not recall exactly which Effects.
Good luck,
Hunt

The only effect that has a histogram is Levels.
Must be a typo in the Help.

Todd_Kopriva Jan 2, 2011 1:56 PM (in response to Ann Bens)Jeff, that appears to be an error in the document. Would you mind leaving a comment on the page to tell the folks working on the document that they need to fix that?

6. Re: Where is Histogram in Three-way Color Corrector
Sengstack Jan 2, 2011 2:44 PM (in response to Todd_Kopriva)I'm aware of only one histogram in P Pro, the one in the Levels effect dialog box. But it's miniscule and changes don't show up in the Program monitor until you've closed the Levels dialog box. Which is not a good thing.
So...does anyone know if there is a P Pro histogram plug-in or something along those lines?
Thanks,
Jeff

Does the waveform monitor help you?

Sengstack Jan 2, 2011 5:45 PM (in response to shooternz)The Waveform definitely helps. It's great for seeing contrast ratio and luminance, left to right across the clip frame. But the histogram is a worthwhile tool to see overall luminance values and get a sense of tonal density for the entire visible area of the clip.

Sengstack Jan 2, 2011 5:46 PM (in response to Ann Bens)I did and nothing showed up. That's why I made the forum posting. Otherwise I would have left a comment with the Help file.

shooternz Jan 2, 2011 7:00 PM (in response to Sengstack)I am guessing you may come from a stills (photoshop) background?
Histograms dont play so much of a part in digital / film as waveform monitors do.
An advantage of the waveform monitor is it will update dynamically as you apply the effect and it is also showing you the "limits" of the display medium.
eg. Black and White.
It also shows where mid tones sit and can easily reference to a greyscale chart.

Sengstack Jan 2, 2011 8:38 PM (in response to able123)Good tips from Robodog2 and Shooternz.
A histogram can be dynamic just like the waveform monitor. But the Levels histogram (the only histogram I can find in P Pro) does not work that way. It displays a shapshot of the currently visible frame. You have to close that dialog box, move the CTI, and reopen the Levels dialog box to see the updated histogram.
Comparing histograms in P Pro with PS shows you how that the two programs view images differently. Why that's so, I don't know. But here are two screenshots showing histograms from both products of the same video frame:
This is the P Pro Levels effect histogram for a frame in a clip.
And this is the PS histogram for that same frame.
The Three-Way Color Corrector, Tonal Range Output display shows you what P Pro sees as Shadows, Midtones and Highlights. You can alter the default settings for what P Pro considers Shadows, Midtones and Highlights by changing the settings in the Tonal Range Definition control.
In any event, this thread started with a query based on what we now know was a mistake in the P Pro CS5 Help file. I have posted a correction to that Help file page.
Bottom line for me...other NLEs and color correction tools have histograms. P Pro, for all practical purposes, does not have one. Perhaps an Adobe engineer might weigh-in on why that is so.
Best regards,
Jeff
