When I find stuff like this I remember why I'm still with Nikon ^_^
Noise Test
It seems like that using multiple of 160 ISO is better to avoid noise during video. It doesn't make sense to me... but this is the truth :)
I hope it can help you guys with Canon gear. |

My (older) Canon has a minimum ISO setting of 80 ... it may be that their "base" setting is 160, and that the best effect will be obtain with even multiples (or factors) of that, i.e. 80, 320, 640, etc..
I'm guessing that any calculation will be less prone to error if fractional values can be avoided. for example, my native image size is 2816 pixels -- for DPC I usually resize to 704 pixels (exactly 25%) rather than 800 because I think (but can't prove) that the resized image will be more accurate if the calculation can avoid using "parts" of a pixel. |
