7D contrast question

I notice that when i open the mov files in quicktime, they have a much flatter/lower contrast look then when i import them into PP cs3. If i play the video back at half size, its less contrasty, and when i go to full screen it gets much heavier. In CS3, its got a heavy contrast look and i even dialed down the contrast in camera to. Anyone know whats going on here? I prefer the flatter look.
 
Yes. The different applications are using different gamma profiles to render the colors on the video. Very frustrating, I know.
 
I guess i should just trust the gamma in premier pro. But now the question is, i love the loewr contrast look, lol, how am i going to achieve this in camera..... hmm
 
What picture profile are you using to start with?

Neutral? Faithful?

I just played around with the 7d with sharpness and contrast dialed all the way down in both profiles and I noticed a slight, but distinct different between the two. The neutral setting had a wee bit less contrast and noticeably less saturation

He's talking about something different here. This one's an application-specific issue, not a camera issue.
 
actually both might be helpful.

Another question:

if i chose neutral, and bring the contrast, sharpness and saturation all the way down, should it not be IDENTICAL to if i went to custom setting, brought contrast, sharpness, and saturation all the way down????

He also asked about obtaining the look in camera, hence why I mentioned picture settings.

What about taking a still and bringing it into picture style editor to achieve the look you want and making it as flat as possible? Maybe that would give you the look you're trying to get.

Have you tried it? When I was fiddling with the pre-sets I just toggle back and forth between the two to see the differences.

I was looking at a box with blue trim, a piece of paper with sharpie writing and some metallic board. Going back and forth on the camera you should be able to see whether or not they look exactly the same or not.

Maybe a custom function doesn't start off as "neutral" as the neutral setting or vice versa.

Also there's an option to change the colour space from sRGB to Adobe. I don't know if that would help you out.
 
definitely worth looking into. because the images looked AMAZINg when flatter.
 
Also depends on what sort of monitor you're using on top of the gamma profile of the particular program. I would assume you're working on something that is pretty well calibrated though.
 
The two images had different looks on the same monitor. And yes, mine is cailbrated. :)

Just gotta figure out which CD gives me the ability to do the picture style editor.
 
Haha I think it's the EOS utility one. I think it has all the programs on it. I am at work, otherwise I'd be able to do more than simply turn on the 7d and play with settings to suggest more helpful answers.
 
I had this problem a lot with my D90 in PPRO, would capture a nice low con image, and then Premiere would just crush the blacks again. The worst part is that there isn't an option in Premiere to adjust the working color space, like you can in After Effects.
 
i'll figure it out, if anything i'll have to do it with color grading, but i liked how it looked amazing raw!!
 
I've been wondering about this as well, the links that el presidente posted are interesting. I did a test, but I'm not sure about the results. I exported an uncompressed still frame from the raw h264 footage using quicktime. I also ran the raw h264 footage through compressor and made a pro-res HQ movie and exported the same frame with quicktime. In the comparison shot below, the left image is the raw h264 and the right image is pro-res. I notice that the orange in the palm tree leaves look a little more vibrant in the h264. Looking at rgb histograms, the pro-res seems a little more stretched out and slightly lower at the peaks. Is this the effect that the articles are describing?

so i found by lowering contrast by 15 units on the editor, it matches the quicktime player footage. Dang, wish that extra step wasn't necessary. Will try to picture profile editor and see if that works.
