Christmas Day, 2006

Merry Christmas, everyone!

I have a couple of Christmas pictures after all.

They were an experiment with my Nikon D70s. I've always shot with it at the lowest ISO setting of 200, for best quality, but the thing goes up to 1600 for low light situations. Although at 1600, the picture isn't as clear. There's digital noise analogous to the grain one sees in higher speed 35mm films

The faster the film, the more prominent the grain. Likewise, turning the digital camera up to 1600 ISO (equivalent) cranks up the gain in the light sensitive photo receptors in the camera, but the cost of doing this is the generation of digital noise.

The digital noise looks similar to the graininess in fast film.

Anyhoo, I had never used my camera with the ISO maxed out like that, so when we were out at WalMart, I had my camera with me (doesn't everyone?) and turned the ISO to 1600 and took a couple of photos in available light, no flash, so that I could see how it does.

The photos are nothing to write home about, but I'm pretty impressed with how good the photos look, despite how the noise is noticeable in them. Plus, I could set the camera at 1600 ISO and -2 stops of compensation, and effectively have ISO 6400. I could open the RAW files and adjust them +2 stops. It's nice to know that I could have such a low light usable camera. The only cost would be some noise, but I'm excited, and wanting to try some serious available light photography.

I know this must be the most boring post in the history of blogdom, but I wanted to put a last little bit of Christmas on here.

Lovely Wife and I are planning to start toward Louisiana in the morning. It's a sixteen hour drive, but we hope to be able to drive straight through, spelling each other in driving.

I have no idea if I will be able to update the blog until we get back on January 1st. So, if you see something new, you'll know I was able to find time to write and/or post some photos.

Merry Christmas. God bless all y'all!
