Moments in Time Photography
A reader has an interesting question regarding the Canon G9 and Konica-Minolta A2 comparison:
If you were to switch G9 to a next-down image size (8MP, no?) would it improve a quality of an image?
(…)
Would this work in the same camera (the G9) if you merely changed the settings? Would ISO400 look more like ISO 200? Could ISO 800 be used at all? How does it all compare to A2?
Interesting question! Read the rest of this entry »
Conrad Electronic sell the Voltcraft K204 datalogger, which is a 4 channel temperature logger. [Note that the above link is to the German Conrad website. The links to other sites are, unfortunately, not the same, so you will have to perform a search on each national site.]
The logger allows you to capture up to 16,000 samples from up to four different K-Type temperature probes. Depending on the probes, a temperature range of -200°C (-328°F) to 1370°C (2498°F) may be covered with a 0.1°C resolution.
The K204 sports a serial port and comes with a RS232 cable. No Macintosh computer has come with a RS232 port for the last … what … decade or so?
I have used a Konica-Minolta DiMAGE A2, which was a fairly high-end super-zoom camera in 2004, for about 4 years. In the fall of 2007, I purchased a Canon G9. So how much progress has there been in the last 3+ years?
Recently I went to India for the first time. What a wonderful place!
I was (and still am) fascinated by the colors, the smells, the bustling business everywhere. The general feel was of vibrant aliveness.
Because my primary objective was not photography, I decided to carry only a Canon G9, not a DSLR. I figured that because of the generally intense sunlight, I would not have to do much high-ISO shooting, so image quality would be acceptable. I also figured that I would deeply regret the shots that I would loose because of this decision.
Well, I was right on both counts. Most pictures were taken in sunlight so bright that sensor density (i.e. the number of f-stops between the highest and lowest levels of light that can be discerned) was the limiting factor, not sensor sensitivity.
And I lost a number of shots because the G9 is so much slower than a DSLR. Try riding in a 3-wheeler cab through dense urban traffic with the driver going like the devil is breathing down his back and then you see an elephant in the fray … by the time the autofocus had gained focus, we were well and truly on a different street.
I am still rather pleased with the results and in all honesty, since the G9 was just small enough for me to have it with me literally all the time, I probably got some shots that I would not have gotten with a DSLR because the bigger camera would have been in the hotel room or in a bag.
Decide for yourself what you think, there are more images in this gallery!

The wild geese took off into the red, pink, and purple sunrise sky. I had a few seconds to capture them, then they were gone.
