You can depend on your Canon Rebel T3i for great low light photography.
Twilight (and dawn) have different light qualities than any other time of day. The conditions only last a few minutes, but it is well worth the effort to take some low light photography images during this time.
One of the biggest concerns about the previous camera models is their image quality when the lighting is not the best. Camera technology has improved by leaps and bounds, and now, you can take better pictures than ever before. This is true of many newer models, and, the Canon Rebel T3i is no slouch when it comes to image quality.
The nemesis of photographers has always been camera noise, and it is especially true of digital cameras compared to film cameras. Noise is the visual grainy effect you see in some photos. For instance, newspaper photos have always been subject to high amounts of noise simply because of the way the pictures are processed and printed using poor quality paper. As a photographer, you do not want your pictures looking like newspaper quality unless that is your goal.
Current models, including the T3i have improved this issue tremendously.
So, get out and shoot even when the sun goes down. Incidentally, you can get some great creative shots in the twilight hours.
As you prepare to get out with your Rebel T3i, consider the following guidelines and recommendations.
1. Try to use the lowest ISO setting possible. Even though the noise levels are greatly improved, you will still get the best results at the lowest settings. Not only will your noise level improve at low ISO settings, but the color saturation will also be much better because of the longer shutter speeds.
What is a low ISO? Generally, you will want to stay at ISO 1600 or less, and if you have a way to stabilize your camera, keep it at less than ISO 400.
2. Bring a tripod. It’s almost a must. Even the steadiest of hands cannot hold the camera still enough when the light is very low. A tripod is the best possible way to keep the camera from moving and shaking.
3. Take your pictures “hands-free.” If you have a cable release, use it. If not, using the timer with a 2-second delay on your T3i is an excellent way to get a good image. The less your hands have to do with taking the picture, the less camera shake there will be.
4. Focus manually instead of using the Auto-focus. Manual focus may be your only option anyway, depending on how much light is available. The camera may not have enough light to pick up contrasts in order to focus. This might be just the time to use Live View with its 5-10x zoom (for focus).
5. Check the histogram after each shot. You can turn on the histogram by pressing the Info button above the LCD screen (next to the Menu button). The histogram shows whether you are getting balanced light throughout your image. If your histogram is too far left or right, just adjust your exposure to correct it.
Using a digital SLR like the Canon Rebel T3i certainly can make photography (even low light photography) lots of fun!
