Shane,

I consider the brent’s point very important. Shall not be forgotten. Native ISOs, loss of DR …

Thanks for sharing knowledge.

David, yea I think it is

Eric, yes it does, much cleaner, but yes, less latitude

Hi Shane,

thank you for your articles.

I didn’t understood your reply tho Josh’s article, in wich he states that ISOs 160x looses about 3/10 stops of Dynamic Range.

However in my reply to his article, I told that I can’t perform a latitude-emulsion test my T3i, because I don’t have a color chart neither a Zone Scale.
I could only test emulsion on my T3i (Magic Lantern allows me to dial ISOs 160x).

So I suggest you to perform some test on Canon DSLRs to check if those 160x ISOs looses 3/10 stops of d.r.

Hi Shane,

Thanks for this great information about tests.
Does this test tell us that the Neutral Picture Style is actually cleaner than the Canon Log? Of course the Log will have more latitude.
Thank you very much!

If I did this right my canon7d also is best at 160,320,640,1250. Testing at. 1080/30. 1/50 @ 5.6
Neutral I tested all ISO at +7.0 exposure in AE Could it be inherent to canon sensors?

Derek, which iso did you use for the benchmark and applied to all others? Thanks

Lawrence Rose. All of the tests we’re shot at a 1/50th shutter. With the exception of the high speed tests that will be shown in part 4. At 24fps a 1/50th shutter is the equivalent of a 180 degree shutter on a film camera.

I didn’t see anywhere where you discuss shutter speed during this test or if it matters…..??

I’m waiting impatiently for it to arrive; I have some projects lined up in which I want to use the camera, but I will shot some tests before production as you wrote here.

I will buy the Canon 1DC for sure! Thank you Shane for all the info.

brentwgraham, I checked out the website and write up which was very through and well written. The push and pull is all right on. I also love the fact that you get a little more dynamic range. I think the biggest take out of all this is that Canon has cracked the fix pattern noise issue on the 1DC and delivery noise patterns that look and feel like film grain and that there is incredible low noise.

Bill Hamell, you are very welcome. No, the lens has nothing to do with the noise level. That is all sensor.

Hi Derek, so that’s how you did it. I’ll go try it out with AE then. Thanks!

Thanks Shane, I know you’re in my country Malaysia right about now. Regret I can’t attend but I’ve seen your presentation at NAB. On behalf of us Malaysians, thanks for making the 19 hour flight round the world and still have time to answer blog comments :)

Robert Shaver. Thanks so much for the kind words and support. Great meeting you as well Masters in Motion. It was a great event with so many passionate filmmakers.

1. The white balance doesn’t matter in noise tests.
2. We did noise tests for Canon Log, and the Neutral picture style because both settings have different sensitivities and noise.
3. The skin tone test was white balanced by eye to what looked the best.
4. I used a light meter to keep the exposure consistent through every Iso. Keeping the shutter angle the same, but dialing down the lighting, and T-stop on the lens to compensate for the increased sensitivity in the higher Iso’s.
