I lurk this forum a bit as well as Dyxum usually to see if there are any new announcements and sometimes to check out what Sony users are thinking.
One overwhelming thing I notice is what can only be referred to IMO as a "fear" of noise grain.
I'm kinda wondering what causes this. Noise grain seems pretty normal, and for the last few decades has been considered normal in low light photos. So what I'm wondering, is if people have a serious problem with noise grain, maybe they should invest in faster lenses as well as better lighting gear in low light environments.
Just a note however, I am a little biased as I am in fact a fan of noise grain in general, I feel it can add a very filmlike element to digital photography, and I welcome a bit of noise, particularly in elements in photos which are not very important. Sometimes I even add noise into photos in post.
Now, onto something I think is important. I think one problem might be a lack of understanding of actual noise control, the number one cause of "Bad" noise in my experience has NEVER been high ISO, but rather poor exposure, sometimes due to a "fear of high ISO" which ironically causes worse noise grain.
So a little test for those who are interested, next time you're shooting in a poorly light environment, go to your normal ISO setting, and then, without thinking, up the ISO an entire step, and maybe throw an exposure bias of +.3 or +.5., set to spot metering, compose and frame where there is light to begin with, Shoot raw, and check out the results.
I have never had a problem taking my gear up to ISO6400. Maybe some of that info can help you guys not have a problem with it either.
