"Acceptable noise at ISO 200 ?"


San Antonio, US
          

The sample is a screenshot of a picture opened in Adobe Camera Raw and zoom 100%.
Is this acceptable noise at ISO 200?

This picture is taken in a room, lit by the ceiling fan/light. On a tripod with cable release.

The final picture, after processing, looks great. But I'm a little worried about the quality at 100% ... or shouldn't I be?

The image is underexposed so you will get more noise even at a low ISO.

As noted before, it appears underexposed. It should be nearly noiseless at iso 200

There's your problem.

>The final picture, after processing, looks great.

There's your answer.

My smarta** response aside, the underexposure other responders have pointed out makes this a pretty poor image to use to evaluate noise performance.

Not to pile on, but I'd say that this is not just underexposed, it's underexposed by quite a bit. Assuming that your electrical plate is similar color to the ones I'm used to seeing, you're at least a stop underexposed even here - and the display shows that you've already boosted exposure by two thirds of a stop. If you're boosting exposure by what appears to be two stops, you're going to get some noise.

Where are you going to display the image at 100%? Answer: nowhere. IMO, peering at an image at 100% on your computer is equivalent to holding a 3ft wide print 17 inches from your face. You'll see a lot of flaws but won't be able to appreciate the art.

Could it be better with better exposure (and white balance)? Yes. Would you notice it at reasonable viewing size? Probably not. Blow any digital image up far enough and you will find some noise. You can minimize it by not underexposing and you can clean it up with noise reduction software - so it looks good at reasonable viewing size. I rarely view images at 100% because I'm not a masochist. There may be a reason to do it, but for me it is usually some level of academic inquiry/comparison, not to see if I have a keeper.

Don't worry. Enjoy your art.

Based on the positioning of the sliders I would say yes. When you jack up the exposure, and shadow recovery and drop the highlights by the maximum amount I would be surprised NOT to see this kind of noise at ISO whatever.

Thanks for the advice everyone.

This corner section of the room is away from the window. It's a small portion of the picture. The overall picture is correctly exposed, but this is a 'dark' corner in the room, so to make it more light, I opened up the shadows here but wasn't expecting this level of noise.

This picture is of the house's 3rd bedroom (this is actually our house that we just listed for sale).
The 'full' picture is here: http://bit.ly/ZjsFhy

Thanks again!
