So basically, ISO is the same thing as the Gain function on a typical video camera. Boost the Gain, you'll get a brighter image at the expense of visual noise. Boost the ISO, you'll get a brighter image at the expense of visual noise.

thats the basic idea...however not all ISOs are equal and they vary on each camera. For example this past weekend shooting with a 2 7Ds 500 on one camera was visibly nosier then 500 on the other camera.

With that said I'm pretty amazed but the noise floor in these cameras even at pretty high ISOs and its getting better, I would expect that the next generation of cameras in the next year or two will have amazing ISO performance

Indeed Robbie;

How things should work vs how they actually do (i.e. variation in factory specs). Always best to test the equipment you own/use for these surprises, before you shoot. Here's a simple test for any camera http://vimeo.com/19579012 showing the "magic" ISO's in the multiples-of-16 that DSLR's favor. Of course: test it yourself...ML

that's so weird how you can watch the noise increase, then it suddenly drops when you hit those particular ISOs that were listed at the end. Defies logic, I must say. Great vid.
