HD profile Slide or Negative contrast
on Jun 17, 2005 at 2:39:11 am

Did some recent tests with a Panavision HD CAM in daylight, noon, no fill. Kept the highlights down, but image had mondo contrast through the viewfinder.
Lots of blacks, few highlights, and not a lot of grey. I did not see dailies on a CRT monitor, but on set the color LCD mini monitor still looked
very contrasty.
Protected the highlights and figured the black lattitude would eat into all that black.
Thinking if this goes to video, it's going to look bad.
If to film will the greys come back?
Seems like this is a pretty difficult dilemma -- if you do not know final output, film or video.

Here are the menu settings:

Hi James,
was DCC on?
Looks like you shot with shutt off, so movement will be blurred.
Gamma number 6 would have been better.
Don't use LCDs for contrast evaluation and black detail evaluation.

I don't follow your comment about not knowing what to do if you don't know what the final release is going to be.
This is what grading is for!

Tell me, if you shoot film in broad daylight would you use fill?

Michael:

This was a totally run and gun situation, no I would not have had the opportunity to use fill in this situation.
My question was really about grading, I do not know if this is going to a film festival--to film, or to broadcast.
If it is going to broadcast, can you explain how grading would overcome this level of contrast, my main source of evaluation was
with the viewfinder, a grey scale source, and zebras, a combo that I always found very accurate in broadcast situation. I don't think
you can go both ways with this. Please enlighten.

Try and get a grade for film out as well as a TV version.

If not go for a film grade. Retweaking a film grade for TV is a better approach than the other way around. (it would only take resetting some gammas and shaodow levels to get the film grade "close" to TV.

Keep a copy of non graded master.

Hard to comment beyond my general observations on the original camera setup lighting ect.
Someone who regularly shoots HD f900 may be able to let you know if what you did was in the zone or over-protective of highlights at the expense of shadow detail.
I've seen rushes from movies where there was no significant highlight detail above 80 ire. Not saying this was the case with your material.

Thanks for the comments, it is easy to get a few good frame grabs if you are shooting 25 of 'em a second for 50 minutes:)
Let me know how the grade pans out.
