Highest ISO for 8X10's?

[dennykyser]

I am hoping your expereience can help me here. What is the largest ISO you would use to get good quality 8X10's. I will be taking some outside shots with the 70-200 f/4 and probably even with the 1.4 extender. So will be at 5.6 or 8.0 f stop. I will be shooting deer in the evenings and know I will have to step up the ISO but dont want to over do it.

I will be using a 20D or a 10D, and a good tripod.

With the 20d I have seen great 11x14's printed that was shot at iso 1600 and above. If you expose correctly you can eaisly print 8x10 at iso 3200 with the 20d. Now with the 10d I would not go above iso 800 without running noise reduction before printing.

Which Camera?

Really, this is too subjective to both personal opinion and subject matter for us to be much more help than just a gut reaction.

I have printed 8X10 from 10D photos taken at ISO 3200 (noise reduction was used in processing) But ony because I had to shoot at 3200.

The rule of thumb is to shoot the lowest ISO possible for the job while maintaining shutter speed.

But in the end IMHO if it gets the shot.. even a grainy 1600-3200 pic is better than none. ;)

Thanks guys, I have always been a 100 iso guy from the film days, I never wanted to get that perfect shot and not be able to blow it up. I dont believe I would ever have to go over 800 iso maybe 1200 max but to be honest I thought that would really show. I have not played with the iso much, as you can guess its always set at 100. I have to get it out of my head to lean against a tree, hold rock steady and shoot a slower shutter speed. :)

I may check back later and talk to you about the noise reduction if I run into a problem.

Thanks again for the help,

I shoot both but I see it would definatly be to my advantage to use the 20D whenever possible in these conditions.

I do a lot of 13x19 and 400 looks great, sure 100 is better

The 20D has made me less concerned with pushing my ISO when needed. My wife and I spent the weekend in the Everglades and we were shooting long lenses most of the time. I kept telling her not to be afraid to shoot at 800 or even 1600 in order to get fast shutter speeds. She was very pleased last night when she saw the results. If you want cleaner images you can always run them thru NeatImage or similar.

You could always Neat Image it.

Couldn't agree more.

I just had a calendar made which had images that were larger than 8x10 on each page.
I had many ISO1600 images in there, and you could not tell by looking which were ISO100 and which were ISO1600.
Seeing an ISO1600 image at 100% in photoshop is one thing, but then viewing the actual printed image is quite another. Even at large sizes, noise/grain from the 20D is not very visible. And it's definately not enough to ruin any print.

Well as it is pretty subjective why not take advantage of the immediacy of digital.

Assuming you have a PC and a decent printer, just take a few shots of anything in your house at 200, 400, 800, 1600 ISO etc.

Look at them on the PC and if that is still not enough to decide print a couple of 10 * 8 s and have a look. It will take about a half hour and cost you for the ink an paper but you can always keep them for later reference and you will be able to decide which ISO setting is OK for you.

Thanks, good idea
