My understanding of the ISO setting on digital cameras is that, unlike film-cameras, changing the ISO does not evoke any physical change in the camera. Rather, it simply tells the camera to multiply ...
I understand that as I increase ISO, I'll increase the amount of noise in the resulting image. With a constant aperture I can decrease ISO and slow the shutter speed (assume a non-moving subject, ...
Just curious if anyone can help with this? I am using a Canon 5D Mark II and it seams to be having noise issues at ISO 250 and up and especially at ISO 400? What is going on? In low light when my ...
If I understood correctly, base ISO is in full stop steps from the lowest possible ISO setting on my camera. For example if the lowest setting on my camera is ISO 100, than the following table would ...
I'm taking photos at night with a GH1 at ISO 640 and getting a ton of noise in the dark areas. I've seen a bunch of other peoples night time photos and they never have this much noise. I tried using ...
It's obvious that higher ISO affects the photograph by adding noise or grains. But will that grain or noise be distributed equally over all parts of the photograph, or will it specifically affect ...
To be more specific this image is always used by Digital Photography School for ISO comparison. What are those features that make this image suitable for ISO comparison.
I have a question about image quality. Does noise in an image is depends upon "Megapixels" or on "ISO"?
What is "ISO" in general, and how is the scale defined? How does the ISO scale for film speed differ from ISO sensitivity as used in digital cameras? Is lower ISO always better?
So my D90 offers "High-ISO Noise Reduction". Sounds like a good thing, but obviously there must be a cost of some kind. The settings are "Off", "Low", "Normal", and "High", and the default is ...
