Flash Photography and Canon Digital Cameras: Part One by Tim Harris

Using a flash to take pictures make seem like just a point and shoot thing for most people. However, to master the technique of good photo taking with a flash require mastering some skills. This is due to the fact that flash photography works in micro seconds and our eyes cannot distinguish the differences within that short period of time. In addition, we are also not able to see the flash working as we are looking through the viewfinder of the camera. Here in this guide, we will show you how with 5 simple tips you can achieve better flash photographic techniques.
External Flash versus the Canon Internal Flash unit.
Generally when we take pictures in settings like a restaurant or party situation, the use of an internal flash is more than adequate because the subjects to be photograph is usually at a close distance. The power of the internal flash unit will be powerful enough to illuminate the scene. Although the light from an internal flash is harsh, the conveniences of not lugging around an external far outweigh its drawback. Nevertheless, if the situation calls for a more professional photographic quality, you will need to use an external flash to do the job. By using an external flash, you will be able to soften the light of the flash unit by reflecting the light off the wall.
Compatibility of Old flash Units with the New Canon EOS digital camera.
Depending on the type of flash that you have, Canon Digital Camera only uses the Canon Speed-lite Flash with those models ending with "EX". Other models like the "E" or "EZ" models will not be able to work with the Canon EOS Digital camera. Those from other manufacturer require that they support E-TTL flash metering in order for the flash to be compatible with the Canon EOS digital camera.
Why internal flash produces lower quality photographs.
Natural looking soft light comes from a large area. As such an internal flash unit cannot replicate soft light as in the real world. This is because the flash unit is located near the lens of the camera and only illuminates a small area. To get around this problem, what you can do is to bounce light off the wall onto the subject in order to soften the light. This way you can get a more natural looking picture when you illuminate it with soft light. On the other hand, you can also use a diffuser to diffuse the light so that you also achieve the same result.
Overcoming Red Eye effect while using flash light.
The most common problem when using internal flash to take a picture is the problem of "Red Eyes". This happens because the red blood vessels lining the retina of the eyes reflect back the flash light back into the camera resulting in the subject eyes glowing red in the photos. Taking pictures of animal also produces a related problem but this call the "Green eye" effect because of the color pigment of the animal's eyes. When you use an external flash, you will be able to avoid all these problems.
How to take photos in rapid succession using the flash.
After a flash unit has fire off its light, it will require some time to charge up. Therefore if you keep taking pictures is rapid succession you have to make sure that the flash unit is the "Rapid Fire" type. This just means that the flash will work even though it has not reach it full charge. Don't forget also that the batteries play a part in the ability of the flash unit to charge quickly too.
