I've been shooting with a digital SLR a little over a year now. So far the fundamentals of shooting film have applied to digital except there's one thing I don't understand.
With film, shutter speed and choice of film ASA affects image "saturation" and grain. More of a concern with monochrome film, low light / low contrast images or fast shutter speeds.
Does this apply to digital photography? Does a digital image get "grainier" as the ASA setting goes up? Does changing ASA effect the photocell's sensitivity or only boost the amplification?(gain) How does ASA affect contrast? Does choosing a higher ASA setting to achieve the fastest possible shutter speed degrade the image? Is there such a thing as Image Saturation with digital?
I've been a member of A.net over a year and this is my first post in this forum. I've shot motion, stills, film, video, belonged to IATSE for over 25 years and I consider this forum intimidating. Members who post here and members whose photos have been accepted by A.net make me feel like a beginner again. Very impressive work.
Thanks in advance for your help!
