"Annika1980" wrote in message ... Here's a test shot I took of The Mighty Jewel tonight using only available light (from a ceiling fan). This is an actual-sized crop, but it's still a big file. http://www.pbase.com/bret/image/34174309/original 1/25 @ f/11, 1600 ISO What's the point of ISO 1600, if ambient light is enough for F/11?. Find some ambient light that requires 1/25 sec, at F/2 or f/2.8, and ISO 1600 or ISO 3200. Then let's see the results. In my view, there is only one reason to use ISO 1600 or ISO 3200; when light is so low you have to. Therefore, only such light is relevant testing. as far as I'm concerned. Patrick |

20D @ 1600 ISO !!!

I guess you haven't thought much about retaining sufficient depth of field in close shots like this?? At 2.8 or even smaller (like 5.6 or even 8), this doggy's eye's might have been in focus, but little else would have been. This quality at 1600 allows for flexibility to use ambient light AND allows for substantial DOF using small apertures. This is a HUGE benefit, and is a perfectly legitimate demonstration of a useful aspect of any camera's ability to avoid noise. |

Very decent, this 20D has a damn good sensor. Thomas |

Very decent, this 20D has a damn good sensor. It is especially impressive given the fact that it's packing another 2 million pixels into the same size as the 10D. This usually leads to more noise, but Canon seems to have manage LESS noise, or at worst...the same amount. It looks like less to me. |

It is quite impressive, but the nature of the fur, which makes up 90% of this shot, masks a lot of the noise. I'd like to see a shot of some smooth coloured glass or plastic under similar circumstances. -- HooDooWitch (NaCl - Gratis) http://www.usefilm.com/photographer/51251.html |
