ISO - The Next Step
The first thing I played around with in the creative modes on the Canon was the Manual Exposure Mode. This leaves the shutter speed, f stop and ISO in the photographer's hands. I wanted to get a good handle on one thing at a time, so I started with ISO. Still housebound due to extreme temperatures, the next obvious subject was the dog. Not a toughie, because she isn't too excitable and will lay reasonably still for minutes at a time.
The room she was lying in has a large window and lights up well even under grey skies.I set the white balance to auto and adjusted the ISO to 1600. The f stop default in the mode was 5.6 and the shutter speed at 1/60. I also set the Picture Style to Monochrome for black & white and manually adjusted the focal length to 43mm. This was the first non flash picture taken.
Not bad. A little heavy on the highlights on her belly. I took a look at the White Balance settings and saw there was one for overcast conditions. I set it, then snapped another one at 55mm.
This turned out pretty good too. I was pretty exited about getting images this clear and not being dependent on the flash like the Kodak. The next project would be waiting for a slightly warmer day and trying the ISO experiments outside. I had to wait six days for the first opportunity. We finally got a blustery day with a high of -8C. Time to rock 'n'roll. The day was overcast again, but I was thankful for that to avoid a lot of glare off of the snow. Went for a walk down by the river and practiced doing shots of bare trees and shrubs.
I reset the White balance for sunny conditions, since it was still pretty bright out there. Again set it to Manual mode and Monochrome. Lastly I set the ISO to 400. Completely blown out white shot, so I dialed it down to 100, the lowest setting.
Not that great. Still quite whited out. I thought that it might be worsen by the sky which looked a lot darker, but was still the sky and emitting light. Reset the white balance to overcast and tried one more shot with the river and Nuns Island as a backdrop.
Nope. It was clear that the wind coming up didn't help the photo at all. But there was still the light haze to everything. Back to the drawing board. Tomorrow I'll show you what happened when I started playing with the shutter speed.
