iso speed

what sucks is when your iso is for somereason set on 1600, and you go to a photoshoot the next day and ALL of your photos are taken at 1600

im usually at 100

Usually, I'm at 1600. Occasionally ISO 3200. I shoot a lot of concerts . When in the studio, ISO 100 or 200, when outside: Varies.

I leave my cameras (5D & 10D) set to ISO 100 by default, and adjust upwards acording to situation and requirements. The other night, I was shooting 1600 & 3200 on the 5D in a dimly lit club. Earlier that day, I was doing landscape shots with a Grad ND filter, and had to go to 200 to keep the shutter speed high enough with f8-f11 for good DOF.

So, it depends . . .

This is a pretty open ended question and one that will recieve alot of different answers. For your specific question of ISO for landscapes I will normally start at 200 and move upwards from there depending on the available light. Also depends upon whether I am working off of a tripod or not.

Most of my landscapes are shot handheld. I would guess that at least 90% of my landscape shots are done at ISO 200. The visible noise difference between 100 and 200 is a non issue so I almost always start at 200. I've done enlargements up to 30X40 from ISO 200 images and there is no noticeable noise.

One has to be comfortable with themselves as to what shutter speed they can handhold and still have an expectation of a sharp image. Couple this with what f-stop you want to have to attain the kind of DOF that you want and is your lens IS equipped or not and you come up with an equation that is difficult to answer in a simple response. I very rarely ever go above f/11.

My advice is that one should not be afraid to move up the ISO scale in order to get a camera shake free image. The more recent Canon bodies handle noise very well and add in the noise management utilities such as Neat Image and Noise Ninja you can shoot at relatively higher ISO and still have very good images.

Use the lowest ISO you can get away with. Depends on the situation. I keep my camera preset to 200 because that handles most situations well.

Here's some proof:

So I think it's "faked", so to speak. Since I shoot RAW, I tend to prefer underexposing at ISO1600 and then push it in RAW converter (I need this since I shoot concerts in very low light situations). This way, I get three choices of faked ISOs and there's less chance for overexposure (see: http://www.cs.duke.edu …raphy/faq.html#​isovsboost)

I think that this "faking" is why Canon calls it the "H" mode rather than ISO3200

Oh man I've done this a few times, and sensor dust man got to check these things before I go shooting everytime, had this big feather like thing in my sensor appeared in all my pix, one blow it was gone =( poop!

with a tripod, i even shoot nightscapes at ISO100. In general, i leave it as ISO100. bump it up only when I need to on a case by case basis.

It would be nice if when powering on the camera, the display shows you the current ISO large and beeps, cuz i've done that also before.

I'm mainly a motorsports shooter. I usually shoot in manual, select the shutter speed I want, and then adjust my ISO setting until I've got enough DoF to get my subject sharp front to back. Usually means I use a range of ISO settings across the day depending on light levels etc.

I use the smallest ISO (usually 100) that I can get away with and still get what I'm looking for.

I have found myself lately shotting at extremes. One evening I'll be at 3200, the next 100. I've gotten in the habit of shooting a junk shot of something like a trash can or a pole, anything for a dummy shot immediately when I turn on the camera, then viewing it along with the info on that shot, just to make sure my settings are where I want them. Otherwise, I forget about AWB, ISO, and also if I'm in RAW or Jpeg.

3200 on a 300D? How do you do that?

damn, im under 400 ISO at a show, unlesss im shooting black and white, thats theonly time in life i put the ISO above 400.

I have hacked firmware! It allows 3200. Here's a shot I took on Sunday. I do have to do some serious PP to get rid of the noise
