Photographing at Twilight
This is the most beautiful time of day to photograph cities and architecture. I distinguish between night photography, which is characterized by a black sky, and twilight, where the deep cobalt blue sky is a beautiful backdrop to the illuminated buildings.
Obviously, the light level is very low at twilight, and many students increase their ISO to 1600 or so and hand-hold their shots. This is not the right approach. With the higher ISO rating the quality of the image suffers. The additional noise that accompanies the ISO increase is unattractive, and the reduction in resolution in never desirable. The color and contrast are also affected, and the result is just not very pleasing.
If you are going to shoot at twilight, do it right. Use a tripod. It seems to me that there ‘s no sense in spending a lot of money on good camera equipment, expensive computer hardware and software, and photo instruction if you’re not going to take the time to get high quality, sharp pictures. Everyone agrees that tripods are a burden to carry and they slow you down when shooting. But in some situations they are essential, and twilight is one of those times when they will make or break the picture.
The photos accompanying this area were taken at twilight: in Kuala Lumpur, Malaysia. I used 100 ISO for both because of the superior quality, and a tripod gave me the luxury of using long exposure times due to the low light. If I find myself in a situation where I don’t have a tripod at twilight, I’ll rest my camera on my photo backpack or some other support that acts as a tripod, and I will still use the low ISO rating for maximum resolution.
In a way, zoo photography is more challenging than photographing in the wild because the environment is usually unnatural and/or distracting. Chain link fences, artificial rocks, and too much dirt on the ground seriously detract from the subjects. In addition, animals are rarely animated. Indeed, they look bored.
Besides an improperly exposed photo, the other most common mistake beginning photographers (and sometimes the pros) make is not getting a photo that is in sharp focus. There are times when you may want to have an intentional blur in your photo – perhaps to show motion. But most of the time, the sharper your photo the better. The automatic exposure feature of your digital camera is often good enough to for a sharp photo. There are times, however, when you will want to take control of your camera’s settings to get an even better picture. Here are some tips to help you consistently take sharper photos.
Shutter speed is one of the most interesting adjustment to many photographers. A digital camera’s shutter speed allows you to freeze action or use motion blur to create many interesting and stunning visual effects. Shutter speed is dependent on the length of exposure and is expressed in fractions of seconds.
