Dumb question: Which ISO do you normally shoot at?

If I graphed ISO vs shutter activations I would have huge spikes at 100 and 3200.

I keep it as slow an ISO as I can. When using film I used ISO 50 and 64 film mostly.

Yeah - remember good old Kodachrome 25? That was a sweet film.

When I shot film I almost always used ASA 100 (ISO). Today with digital I shoot a lot at 100 but I'll change in a New York minute if the situation looks like I should be using something higher.

Out here in the Pacific Northwest the weather sometimes changes so quickly that a New York minute is just too long!

I do mostly outdoor photography, concentrate on wildlife, and have gotten into the habit of just keeping my ISO at 400 throughout a shoot. I just have to remember that when I set up to do a landscape shot, ISO 100 is the way to go!

I do want to experiment more, though, with higher ISO's in low light...I don't like the noise that you get, but with a minimum of cropping/enlarging/amp​ing up the exposure and such, I think I'd have a lot of fun in the right setting!

I heard that Tony.

Here the sun is almost my enemy. I keep a polarizer on just to blunt the sun. I've visited your area and of course adjust the ISO to suit.

My choice of ISO, F Stop, and shutter speed are all-variable depending on what I try to accomplish when taking a particular image. I think it is a bit narrow minded to always shoot at the same fixed ISO for all outdoor shots or all indoor shots.

As low as the situation will allow me to.

bbbig,
I always have my cameras set at ISO 100 (yes sometimes I forget) and only bump it up as I need it. I don't set a standard except to always strive for ISO 100 even when using flash. Obviously this isn't always possible and then I bump it up as needed.

Oh and its not a dumb question

exactly.

Start at 200 and go from there. I'll adjust up or down to get the shutter speed or aperture that I want.

I shot some Kodachrome-25 but mostly all Kodachrome-64. I guess I'm a bit older than you, I remember Kodachrome-10. I keep some Kodachrome-64 in the freezer for whenever and have never even tried Kodachrome-200. I'm glad there is still one lab in the U.S. that does K-14 processing. Kodachrome-25 was a very, very smooth film.

Have you ever been to New York?

I also only go for major backgroud blur about 40 percent of the time, so I commonly shoot at apertures between 5.6 and 11, even though I am mainly a portrait photographer.

This makes no sense ... you say you go for major background blur but you stop your lens down as far as you can go on a 1.6 crop sensor?

If you want to eliminate/blur the background, you need to open your lens up. f/1.2 - f/2.8 would be more like it.
