I took my old Canon Powershot G3 out with the infrared filter on it (cuts all but infrared light from entering the lens) and went to a couple city parks in my home town. When I got back home and started editing my files, I could see that I’ve been spoiled by my DSLRs. I’ve gotten used to seeing a certain level of image quality. My new EOS 7D blows my old EOS 10D away, and this little point & shoot with a tiny CCD sensor can’t match either of them.
Back in 2002, before mirrorless ILC cameras started coming out, the G3 was top of it’s “prosumer” class. After more than ten years, it’s showing its age and has developed some “hot pixels”. As I understand it, a “hot pixel” is one which is always on 100% and doesn’t show medium or dark tones. A “dead pixel”, on the other hand, simply doesn’t pick up any information. The hot pixels are easy to see and fix using a clone tool in the image editor software. Also, the images are extremely noisy sometimes, even at ISO 50. That’s right, the G3’s lowest ISO setting is 50. Even cameras with smaller sensors like this have come a long way with in-camera noise reduction. These pictures are are RAW files from the G3 and I have not done any noise reduction in software, only contrast and sharpening.
