Noise at low ISOs

[Jordan Scott Price]

I use the Marvel Cine profile, and feel it is the best one out there for people who are doing post.

I use this too for all of my narrative work.

They all had noise in that specific blurred/dark corner though, even beyond dark areas, the 'blurred' areas have been giving me the most trouble since day one...even if the color of the blur is not that dark!

Yup, that's just the look these DSLRs have. Anyone else telling you otherwise is blind or happy about it.

Even in the best DSLR shot videos, in the best music videos by Joseph Kahn, In Philip Bloom's videos, in Shane Hurlburt's videos, in TV shows like House or True Blood or Numb3rs... it's there.

That swimmy, processed, blotchy dancing noise. It's very different to film or a professional camcorder grain. It just wont stay still, and using a picture profile like neutral and a program like Neatvideo wont eliminate it.

I don't know if it's the compression (although Nikon's video doesn't exhibit it as bad), or if its the debayer or processing algorithms.

We'll just have to live with it as the flaw of this kind of system :violin:

Bump!

I have been reading about this a little lately. Something I have been wondering, now that I am literally inches from purchasing either the 7D or 5dMKII, is whether the sensor size matters as much as the exposure. In some noise comparisons between the two it is obvious that noise is present in both. My question is, is it really that noticable? I mean, to the untrained eye? Would I be better spending a little extra to get the larger sensor? Or is it as I suspect, and really I just need to plan around my lighting situations when shooting?

I would really be happy with either one, but they both cost a dime or too and I would feel silly for selling my self short due to my own ignorance of the technical aspects.

Thanks!

In a controlled scenario, it would take a LOT of effort, even by someone trained, to tell the difference. But as conditions move away from the ideal, the larger sensor will have more of an advantage in noise simply because it can gather in more light.

If you are controlling the lighting when you shoot, the 7D (and T2i) offer some significant advantages, not the least of which is 720/60p which allows you to shoot overcranked for certain things. The improved screen on the T2i is also a very welcome addition.
