Title: Native ISO or hightone priority?
Post by: Mikkel on January 20, 2013, 05:50:33 AM
Hi! All you out there.
I'm brand new to ML, have just install it on my 600D (Cool stuff!!!!!)
Normal i try to let the ISO be on 200, with Hightone priority on (think it works nice in the highs)
I read that the 600 have an native ISO of 160 (anybody know if its true?). So now i have to deside if i shall use 160 or do as before.
Have anybody expirience on that? (shure i have to make my own, i know) I try to get as much dynamic (details) and as little noise as possibly (Yes i know that the foremost important, is right exp.) I would use Cinestyle as pict.style (for stuf that should be graded).
English is not my native lang€%& Sorry!

Native ISOs are multiples of 160 (160, 320, 640, 1250, etc.). These usually give you less noise than the other values.

With regards to HTP, I suggest turning it off as it increases noise.

Thanks Malcolm, it's really cool with all this knowledge here
I think i better stick to them (the broken ISO) and disable HTP, as you (and Jorgen Escher) say

Welcome! Other cinematographers like Vincent Laforet and Philip Bloom also suggest these settings. Best thing to do would be to take your own samples and decide whichever you like best though, although not everyone has time for that  ;)

No, and if it's not a problem all the time, as you and other says, it's much more difficult to recognize, perhaps first in post!! Its not necessary to learn the hard way every time
