Default iso 800

I was just browsing some of my shots and was wondering how high you will raise your iso to get a shot? During the day I know I can push iso 1000 I get good results if I need too. I haven't done it besides for testing my camera's limits. At night with proper exposure and a some what well lit area I can get away with iso 800. If the subject is stationary I won't shoot that high but sometimes you need too. What abaout you 5d owners. You should really be able to get good shots at high iso.

Both shot at iso 800.

I have seen noise/grain in photos that I shot at ISO 200 during dark conditions (storm clouds) and I have a shot in the database accidentally shot at ISO 1600 in bright sunlight, with very little noise.

I'm shooting with an XT Rebel, so I don't think I really have the range that others have.

Nothing at 800 ISO, but a handful at 400. I DO have some at 800 ISO, but nothing I'd submit to RP.

Oh, gee...why wasn't that rejected for cloudy/common? Mine was....



I guess the locomotive in my shot was more "common" than yours.

I really like both shots. Maybe a bit more color in the sky Jim, to make it pop? What iso? That would be a slight adjustment resubmit if you ask me.

ISO 640...almost there! haha

And despite some of the other juiced photos from this moment in time, there was no more color in the sky. I really don't want to create a "fake" scene, if you know what I mean.

640 is high also. We are always preached about keeping the iso below 200 unless you really have to push it to 400. So it is neat to see what some of these cameras are capable of. I know my XTi is a 400 or less shooter unless it is daylight.

With your rejected shot, what was the shutter speed? You know slower shutter speed with saturate the sky in camera in a low light condition. Then you wouldn't be juicing it, it would be in camera like motion blur. I agree with streching reality a little to get some pop. I know not everyone agrees. Look at portriat photography and all the face touch ups that are done. But I like it as is and think it would look good in the database.

Shutter speed was 1/100th.

Here are a few high ISO images not in the database:

From those examples Jim it doesn't appear noise is much of a problem at all at those ISO settings.

I have a Nikon D90. ISO 400 is excellent, compared to earlier generation cameras. Above that is hit and miss. Here's one at ISO 800 that looks fine:

On the other hand, I have shots like this one at ISO 640 that look noisy to me.

I have discovered that above ISO 400, I need to frame the subject more tightly because a heavy crop will show the degradation in quality.

I have a Nikon D70, and I always keep my ISO on 200. That is the lowest ISO on it. Even on sunny days, I have submitted some shots at that ISO, and have gotten noise rejects.

ISO 1000 on the 40D. I'm pretty happy with the results - looked a lot worse before a round of noise reduction.

If it's sunny I keep the ISO as low as possible without going slower than 1/500 or F5.6 - usually that means 100.

I've always had a problem shooting night shots. Is it better to shoot at a high ISO at F2.8 or lets say around ISO 200 at F8 or 10? I've been practicing a little, but am having trouble figuring out how moving objects turn out before I take the shot. I guess I don't enough experience there yet.

Here's a couple of test shots before I start incorporating the CTA into this. I guess I can freeze the train in a high ISO, but get pretty light streaks with a low ISO. But seems to me that the quality is better with a low ISO.

Some very cool ones, too. Nick, I missed that shot of yours on July 2. Excellent work, man!

I've never feared high ISOs, I just do noise reduction and it's always good to go, I've never had a shot rejected for noise that I wasn't able to subsequently reprocess successfully.

But this one is a special favorite, ISO1600, original dRebel, I just like it. Obviously a ton of noise reduction but it ended up with a nice texture, sort of. I wonder if it would be accepted today. But then, I've never had much of an eye for noise; for that reason alone I can never be a screener.

That's a nice shot. It did a pretty good job of freezing the action but the noise is also pretty obvious. Did you also do a time exposure with a lower ISO, Janusz? Or, was this a shot that you didn't have time to set up for with tripod?

I feel your pain Janusz, I suck at the noise seeing too!

Alot of my night shots have some noise in them, because I can't see it.

I was traveling on business, no tripod, so handheld. Got lucky, actually; I certainly wasn't a night shooter back then and am not one now.

The dRebel is pretty noisy compared to more modern bodies, even my 20D is much better.

Wow, just went back and checked, 1/20, 85mm, no IS. Lucky. Maybe I made my own luck. Always try a shot, you never know how it might turn out.

Not train related but attached is a 100% crop of the lead singer of a band I was shooting with a buddy's 5D MKII @ iso 2000. No processing done, just cropped from the 5,062 pixel original and saved at 94%.
Phenomenal camera.
