I had once promised that I would write more about photography and now finally the time has come! I would like to share my learning with my Canon 550D. In this post I will just talk about my shots from the Oktoberfest, where I tried to shoot different rides in the evening, when the rides were brightly lit.
The picture I want to talk about is the shot of a ride called ‘Frisbee’, one of the most popular rides at the fest. It has a big circular disc which can rotate on its axis and also swings like a pendulum. Since I wanted to capture the colorful light, I had to reduce my shutter speed to 4 secs. Shutter speed basically tells me how much light goes into my camera. Longer the time, more light goes into my camera and for so long my lens will be open to capture all the information. I could have captured the same at may be 2 secs shutter speed but then I could not have captured the rotation motion of the disc. At this point i also took care that my shutter speed is not too long, which would distort the whole picture by letting in more light and also because of the fast movement of the disc. So, I chose the shutter speed which was good enough just to capture the movement and also its the approximate time that the disc stays at its topmost position before changing its direction. Now that we have set our shutter speed, it is also important to adjust our focal stop. In technical terms, the focal stop or f-stop is the ratio of focal length of the lens to the aperture size. In other words it affects the light gathering area and helps to make our subject distinct from the background. Since I did not require any distinction between my subject and the background and I also wanted to reduce the amount of light going into my camera without changing my shutter speed, I had to increase the f-stop to f/22. As I could capture the image I wanted with these settings, I kept my ISO at 100. These three main settings play major role in photography, shutter speed, focal stop and the ISO.
Last but not least, I want to quickly talk about the lens I used to take the shots. Since it was very crowded and I did not have the kind of place I needed to capture the entire ride in my frame, I used my wide angle lens. All the pictures here are taken from my Sigma 10-20mm F4-5.6 EX DC lens and according to me it does a pretty good job.
Few more basic but important suggestions:
1. Most of the night photos might require post processing and hence I would suggest taking the shots in RAW format.
2. Always use tripod for night photography.
3. Try experimenting with different settings. The photos which might look good on the camera LCD screen might always not look good on the computer screen.
Enjoy the rest of the pictures and let me know what you think about them. Pour in your comments or suggestions down below.
