ASA rating and quality
I am begining to look at a digital SLR and have noticed a difference in ASA
rating capability. My question for low light photos is the effect of A qutieSA similar between digital and film. As film photos granular the higher value ASA film used. Since the media does not change as in film does the quality suffer equally in digital. Chuck |

Chuck If I understand your question correctly, yes it does degrade the higher ASA (ISO) you use. It adds "noise" which appears in the image as a grainy look. However, some cameras are more prone to noise than others at the same ISO, and others are better. Just like some films had better grain than others at the same ISO. -- Skip Middleton http://www.shadowcatcherimagery.com |

There is increased noise at high ISO settings in digital cameras. However, the rate of decay is not nearly as bad as the problems with high-speed film, so I wouldn't say it suffers "equally". -- David Dyer-Bennet, , http://www.dd-b.net/dd-b/ RKBA: http://noguns-nomoney.com/ http://www.dd-b.net/carry/ Pics: http://dd-b.lighthunters.net/ http://www.dd-b.net/dd-b/SnapshotAlbum/ Dragaera/Steven Brust: http://dragaera.info/ |
