C100 Samples with various gammas, and WD DR

It looks like WD DR might actually be a useful setting to get closer to C Log DR, although at least a stop less DR it is still much closer than I would have guessed. Looks like Wide DR is set up to bring up blacks, and secondarily to prevent highlight blowout. Not Alexa ProRes but better than similarly priced cameras. On my iPad it appear that Wide DR does funny things with leaf highlights.

I want to see this on a download and/or higher res images, but the first look on YouTube,as viewed on my iPad is very favorable. Wide DR and C Log can both bring up shadow detail in the tree without blowing out the sky, well wide DR half blows out the sky, lighter blue than with C Log.

The video ends by comparing C100 EOS setting to a 7d. It is better even though C100 EOS setting is clearly inferior DR compared to other C100 gammas.

1080p samples now up. C Log, Cinema still best. Hmm. Wide DR works some times, but not always. I need to see these samples on a decent monitor, not an iPad. Looks like wide Dr may reduce highlight contrast too much for some situations, recoverable contrast loss but if you are going to do post go with C Log. YouTube URL for the gamma comparisons is http://www.youtube.com/watch?v=L7pYQuVQrso

Here is C100 samples with a 35mm F1.4. As I post this the video has not finished converting so I cannot see it. http://www.youtube.com/watch?v=uE71YB24kYk

These are nice, but I still need to see a raw file with someone trying to make things pretty. Thanks for posting these, though, every bit counts. It is still more informative than the initial canon video.
 
I'm not seeing a lot of difference between the 7D footage and the much more expensive C100 footage. While somewhat different, it is hard to imagine justifying 5K or more to get a small amount of latitude. Look, I own a bunch of Canon glass and bodies. I'd like to believe that this is better but I'm just not yet seeing the difference. 4:2:0 is not 4:2.2. It's not likely to be much better than a 7D, if I had to guess at a multiple choice test about the theory. But I do like that some of the profiles do save the normally blown out highlights of AVCHD footage. Good to see. I might buy the camera off that alone.

Really? There is nothing out there to shoot? At least shoot a cat or something.

A bush an a sky with wires is a great test!

As for comparing the profiles I guess its a lot more complex as the may have different effective ISO values and may fall apart differently under the stress of post..

I think once you play it on something bigger like a tv, the difference will become more and more noticeable.

Because, (correct me if I'm wrong), the 7D is up-sampling to 1080p from a lower resolution (can't recall the exact numbers off the top of my head) where as the C100 is down-sampling to 1080p from 4k.

After eight months with the C300, the difference between it and the 7D is stark. Everything I disliked about the 7D instantly disappeared. Completely different ballgame - this camera is freakish good, and I would think that the same will be true with the C100 - just less features. Don't get too hung up on the 4:2:0.
 
The post editing house our team is using for our next film told me that among all the cameras out there, shipping or not, the most inexpensive solution delivering footage suitable for professional color grading is C100 C Log delivered through an external recorder. It is actually cheaper to grade than the other alternatives due to the color within the footage. They showed me clips from all the alternatives, shipping or not, and explained in detail why the C100 external is easier for them to work with.

Thanks Tim. You might be right. But the comparisons, seen on Youtube at full frame HD (on a MB Pro screen) don't seem to show a great deal greater latitude between the 7D and the C100. Seeing this, as someone who primarily works for web distribution, and some showings on large projectors (but not theatrical), the two don't seem to be that different for an enormously different price.

Well, I shoot with 7D's and 5D's pretty regular in addition to my C300 - and trust me, the difference is stark. It's readily obvious that the C300 has loads more latitude & resolution, not to mention low-light performance, where it really blows the DSLR's out of the water. The difference in the footage is more stark than night and day. Color grading process is so much better with C300 that there really isn't a place to even bring the two into comparison.

I fully expect the C100 to perform in a similar fashion, especially when paired with an external recorder.
