ISO

Hi,

I am new to all of this...I just bought my first Pentax KS2 and I am shooting a fashion show tonight and I am wondering if anyone knew how high my ISO go before the photo starts looking bad? Any help would be appreciated! Thanks!

That will vary person to person. The answer is, whatever you think looks bad.

What lens or lenses are you using? And how close will you be? Is the venue well lit?

Shoot in RAW, apply noise reduction in post*, and you can clean up quite a bit. It depends, too, on who the audience will be, and how they will be viewing the pics - much can be forgiven if the images are only going to Facebook, somewhat less for Flickr, less still if they will be finishing up as large (e.g. 8x10") glossies directly in the hands of the people you are taking pics of.


* If you don't have Lightroom/Photoshop, Raw Therapee does a fairly nice job of this and is a free download.

A lot of people say 1600 or 3200 as a upper bound, but it really is a subjective issue which also depends on the final image size (web/magazine/large). Furthermore, careful/clever post processing can suppress some of the noise at the expense of some loss of detail.

The bigger issue is the lighting conditions which may force you to use higher ISO. The ISO issue also depends on your willingness to use slower shutter speeds or wide-open apertures which might also make the photos look bad under some circumstances or great if you develop a style that uses motion blur or out-of-focus regions to accentuate the subject matter.

Good luck & have fun!

There is a camera review of the KS-2 that provides comparison shots at various ISO values here on the forum. The review page with the photo's at various ISO settings is here Pentax K-S2 Review - Sharpness and Noise | PentaxForums.com Reviews

That review will also refer you back to the KS-1 review for a more detailed look at noise levels.

You should be able to look at those and see what ISO level will work best for you.

Good luck.

Stay below 800 if you can, but below 1600 is usually not that bad if you plan on doing any cropping. If you have a flash, it may come in handy, otherwise try to use the available light as best as you can. You might want to to shoot JPEG + RAW, that is a setting in your camera which saves your shots. That way you will have both type files to work with.

If you have the camera in hand, you might just want to do some practice shots before you take it out on that first shoot. That should give you some indication.

That would be my advice as well. On my K-3 640 is the highest I like to go. It should be a nice safe number if you just want a mindless set it and forget kind of number.

Thank you everyone! I managed to keep my ISO at 800 and I was using my 50mm!
