Thanks Fstoppers.. this post really helps me a lot
Great little video. The thing that interested me the most was the ISO speeds. Why is it that ISO125 and multiples of it give grainier shots than 160ISO ect? Something I've never heard of!
@Sam, its because the sensor isn't actually going up in ISO to 125, it is simply "brightening" ISO 100.
Sam, I was wondering the same thing. I'm not sure how universal it is but I think there are a few 'real' ISO stops and the others are more or less created with software. Unfortunately these real stops don't coincide with our typical 100, 200, 400, 800 models we are used to. Anyone know for certain and do they coincide across all canon models?
Sam/Patrick,
Canon 7D and 5DII have both been tested as intervals of 160 (so 320, 640, 1250, 2500 etc)
From what I've read, ISO100, 200, 400 etc are the native ISO speeds. ISO125 is ISO 100 +1/3EV thus grainier, ISO 160 is ISO 200 -1/3EV thus, less grainy but you sacrifice dynamic range.
This article explains more about the topic of true or not so true ISO speeds.

Great post Robert. So here is my question then, is there any reason to not just shoot at the native ISO so you get the most Dynamic Range while having more noise than the pulled ISOs? Can't you just clip your blacks a little in post to get rid of the noise and still have highlights that aren't pulled? It's crazy having to think of this stuff since with Nikon we have no control over ISO or SS at all. I only own a Canon T2i and have no option but to use the native 100,200,400 ISOs anyways.
Thanks for sharing. The ISO stuff was interesting. :)
Patrick, clipping the blacks will first affect the contrast of the shoot and then only will the noise disappear. If the noise level is high, clipping will tremendously affect the shoot before all noise is removed. Compressing the blacks is a better solution as it will preserve the overall contrast. The result will be flatter blacks with less noise and also less details.
Jerome, I was asking about clipping the blacks in response to the link posted in the comments saying that the cleanest ISOs are those that are pulled back digitally (160 instead of 200). My thought process was that this could be done in post instead of in the camera and maybe we could do it better than what the camera is doing. Obviously clipping the blacks is going to increase contrast but I'd assume most of the noise would be in the blacks. I just don't want my highlights going gray if that's what the in camera 'pulling' is doing.
is it just me , or there's only 7 videos in this post?
the title says 8.
ooooooooooooooooooooo.....i didn't know that rule about 125ths
not trying to sound assy but "there are some ISOs you really need to try and avoid and they are 125 and all the multiplications of that" but then he suggests to use 1250... can anyone do 125x10? I ALWAYS get 1250...
Wouldn't it be 125, 250, 500, 1000, 2000? 2000 x 2/3 stop pull is close to 1250
ahhhh... so are the ISO stops true for nikon as well? guessing slightly different as base is 200?
Awesome vids! btw, there are only 7 videos but you said 8 in your post. Just a heads up
Hello!
Great vids! Big thank u
I got a question about tip, that we must downgrade contrast and saturation. I know, that its need to got details in darkness, yep?
But! I wanna hear advices how to upgade contrast and saturation in Adobe Premiere CS4 in the best way, after downgrading this parameters on camera
p.s. sorry for crap grammatic. i dont study english Well. I from Russia. I just try to survive
Here is the link of the missing video:

Patrick, about pulling the blacks (160 vs 200), if you shoot video or jpeg stills, the camera would do a better job than you can do in post. That's because the camera can do the 1/3 stop pull down -before- compression happens. The only way to compete with that in post is to shoot uncompressed.
As for the highlights becoming gray, I'd be very very surprised this happens. I can't believe everybody would have missed such a thing, everybody meaning Nikon, Canon, photographers, DPs, Zacuto Shootout,... If we talk about video, the Zacuto Shootout clearly shows whites remain white.
I googled this question of native ISO. Most publications states the only Nikon "base ISO" is 200 and Canon is 100. All other ISO values would be obtained by applying gain to the signal (btw, that's how pro video cameras work).
However this whole concept of native ISO doesn't make much sense as explained here:

btw, great blog! Thanks!
It's good to go back through this and see some basics that you overlook after awhile.
Great vids Philip....albeit, Andrea seriously reminds me of an old girlfriend.. I'll be nice from this point forward....
let me say this... she was allot of fun...
Love Philip Bloom...he is just so fun to listen to!
How was the audio recorded for the indoor tutorials? Great stereo separation.
