Low light noise reduction
« on: February 09, 2009, 02:29:37 AM »
Thanks to Stef., and others, I tried something different last night. I was asked to take pictures at a concert (primarily of the volunteers who organized the event), but was allowed to take shots of the performers. 

The lighting was painfully low. This was in a large church and so it was regular lighting with no spotlighting. Knowing the performance pictures would be used for nothing more than web pages, I decided to downsize the image sizes.

Stef, has always said to reduce the image size to keep the noise levels down. This was shot at a mere 3 MP (small) on the A700. ISO 2000, f2.8 at 1/30 second. Monopod.

Hardly poster stuff, but acceptable record shots for their web pages.

(BTW...this was a fundraiser to help African grandmothers raising their grandchildren orphaned by AIDS. The group my wife belongs to raised $8,000 at this concert.)

I have had really good luck in low light by simply overexposing.  I have shot in terrible light at f/2, ISO 1600 and even 3200 and 1/30 to 1/8 second.  I generally overexpose by 2/3 stop.  In fact, I almost always overexpose by 2/3 stop, even in good light!

This seems like it would blur the action, but the tradeoff is a much improved noise reduction.
