I recently went to the local zoo to photograph the animals there for the colour part of the course. The criteria said to avoid taking photos of manmade colors like painted doors as all the student would be doing was photographing a ‘paint catalogue’ We were told to search for the pure natural unadulterated colours in nature, the vibrant green of foliage, the intenseness of flowers and I decided to start at the zoo. After all with creatures from all around the world there is an entire kaleidoscopic ecosystem of life to photograph.
I captured quite a few photos ranging from the habitat to the actual animals themselves, the results looked good on the lcd screen but when I opened them on the computer I was gutted. So many of the shots I was pleased with in camera were blurred due to camera shake or slow shutter speeds. Instead of hurriedly deleting this images I decided to post them up here to show my mistakes, to work out what I had done wrong and find how to correct this in the future. Especially as the student log is to show the photography evolving.
This photo of a Philippine sail lizard was taken with a wide aperture, and a ISO of 400. I used centre weighed average metering. The image background is nicely out of focus, unfortunately so is most of the lizard, not as badly as it could have been but still the eye slides because there is no focus to lock on to. The essential part of the image, the eye, is blurred so the image is ruined.
The next images of the lizard were more in focus so there are several reasons why the rest of them are blurred.
1. The shutter speed may have been too slow.
2. ISO too small.
3. Camera shake.
4. Even if the camera is on tripod (which is wasn’t)on remote release, the mirror flipping up can still cause a vibration which affects the image. This cam be altered by using mirror lock up so the mirror flips up before the image is taken so the vibrations aren’t noticed.
5. Focal point may be off.
So there are a lot of factors that can ruin a good image. I researched through several books and websites but this was the best one to ensure sharp images.
