What ISO do you use for general shooting with a 20D

[shortie]

Hi All

Just wondering what ISO value you Guys and Gals use the most

I know different shots required different ISO settings but where do you set it before you start to adjust it

It is just I seem to always revert to 100

Hope this makes sense

Sounds like a flawed poll. Most people will likely say they use the lowest ISO that will get them their desired appeture and manageable shutter speed. I tend to leave my Drebel in iso200 when I'm done with it so it's at a decent setting the next time I use it.

I prefer as low as possible when lighting and lack of motion permits, I get a lot more out of post processing that way. I would've voted in this but it appears that my 350D doesn't count. :p

Hi Hellashoot

Your last sentance is probably what I am aming at e.g. what setting do you leave your camera on so that if you need to take a quick shot it is ready to go, I have a bloke here at work who leaves his 10D on 400 all the time this seems a bit high to me

Thanks for the comment

Sorry ericgtr

I just thought that the different noise profiles would make it a little confusing

Thanks for your coment point taken about as low as possible as long as you get the shot

Normally, I am going out after long range wildlife shots, so I need to keep my shutter speed fairly quick to avoid obvious problems of subject motion or camera shake. As a result, in normal daylight, I keep my 20D set to ISO 400. If the light is dimmer, then it goes to ISO 800. In extreme conditions, possibly ISO 1600, although that is rare. Last weekend, I even let it go to (H) 3200 as an experiment. Going the other way, I will crank it down to 100 or 200 only if I need to go that way for depth of field control. Sure, ISO 100 or 200 might be slightly better in terms of color noise, but it isn't that much better. ISO 400 seems pretty good, and it is only the higher ISO numbers where the color noise gets in there more.

So, normally ISO 400 on P mode.

Start out at 200

For wildlife I start at 400 (since I'm usually up early) and soon go to 200 once the sun's completely over the horizon. I hate noise, but hate missing a shot even more. For landscapes it's 100, 100, almost always 100.

Thanks for the input guys

I have standard settings that I reset my camera to every time before I turn it off. Av, ISO 400, F4, no EC or FEC, no strange CFs. I happily shoot anything at ISO 400 and don't bother with noise reduction. I shoot ISO 100 when I use studio flashes, 400-3200 when using speedlites, and generally as low as I can that gets me the shutter speed I want.

As far as I'm concerned, as we're talking digital here, definitely a flawed pole. The idea is to use the lowest ISO setting which will allow for usable aperture and shutter settings.

Be as prepared to change ISO as you are other settings - There is no standard setting :)

Nice to see someone of your caliber using P mode, I don't feel so inferior using it now :) I am learning and working with manual but often find myself jumping back.

I change my ISO for almost every session. I do spin it back down to 100 before I turn it off. For the most part it's just so I have to think about it when I turn it back on again.

I'd say ISO 100 outdoors and ISO 200 indoors - that's my general settings. I shot an indoor convention this past weekend, and ISO 320 worked out best for me (is nice having the intermediate ISO setting on the 1D Mark II N). But as many have pointed out, I generally select the lower ISO that will meet my requirements for shutter speed and aperture settings.
