Here are some shots I took of my block with the Christmas lights on my house. I wanted to show the diffence in the photos @ each ISO settings.I shot the same spot/frame 35mm focal length in program mode @ 80, 100, 200, 400, 800, 1600 ISO @ 6mm focal length. Acceptable shots were at 80, 100 & 200. Unacceptable shots, (too grainy/noisy) were 400, 800, 1600.

ISO-80, f/2.7, max aperture 2.875, exposer time 1 sec.

Great comparison. I've been wanting to do this myself.

Hey! That looks pretty good! Tell me more about that FDR tool?

Does PhotoShot have something like that too? I have PhotoShop.

Thanks again!

Ihave heard thatphotoshop has that feature and so does Paintshop pro that I use. FDR Tools 2 (beta7) is a dedicated program that I prefer to Paintshop pro for this task and is free for personal use

By the way, the combined picture looked a lot nicerbefore I uploadd it. It somehow looks washed out on Steve's site !!
