I will be the first to admit that I used to hate using flash, I would avoid it as much as possible by boosting the ISO or using faster lenses. At least until I learned how to use the flash properly.
The problem with flash is that if used wrong it looks ugly, features are washed out, white balance is off, and of course the big ugly shadow behind the subject, or a shadow created by your lens hood (in the case of some dSLR cameras and prosumer cameras). The inherent problem with any type of flash is that you have a large amount of light and power coming from a small area.
But lets step back here for a moment and go over the four types of flashes available to most photographers. The first type of flash is the built in flash, this can be found in all point and shoot, prosumer, and almost all SLR types of cameras, they’re often small, and offer limited control. The second type of flash is a speedlight, this is a camera flash that sits on the camera’s hot shoe, often larger and powered by their own supply, gives the photographer the ability to control the amount of power it puts off, or allow the camera to control the power settings based on it’s meter. You can also in many cases move the flash head around to bounce the light (which I will discuss later). The third type of flash is a Studio Strobe, these are often big, bulky, and expensive, and not very portable. The final type is not really a flash in the traditional sense, so I will not be going into more detail later on in the post. This fourth type is a “hot light” which is basically lights that are on constantly, just like a traditional light bulb or tube style lights.
But we’re working with strobes, flashes, so I will be focusing only on the first three, built in, speedlight, and studio.

So lets start shooting here, first off using a built in flash. Below is a photo of the built in flash on the Nikon D300, it doesn’t stand out from the body, so if I’m using a longer lens on the camera, there will be a semi-circular shadow. Some SLR’s have a taller arm on their flash to help with this problem, but it still doesn’t help with the fact that it’s such a small surface area.

Below is an example of a photo taken using the built in flash of the D300, as you can see, there’s a dark shadow behind Claudius (the bear), and a semi-circular shadow below as a result of using the built in flash, and at the distance, there’s no real definition to our subject.

So what you need to do is to diffuse the light, by putting something with a larger surface area in front of your built in flash, there are several options available. However it is better to get something with a little more power and control, a speed light. All SLR type cameras have what’s called a Hotshoe, also several high end P&S cameras and Prosumer cameras are equiped with Hot Shoes. The Term Hot Shoe means that the accessory shoe provides a link between the camera and the flash for firing it. Some older cameras have what’s called a Cold Shoe, it is just a place to slide on the flash unit, then you need to connect the flash to the camera using a sync cord. Below is a photo again with a speedlight with the flash head pointed right at the subject. As you can see, the results are slightly better than the built in flash, no more shadow (because the head is far above the camera body) below the subject, but there still is a harsh shadow behind them, because you’re pointing all the light directly at them again. The Built in diffuser on the flash does a little bit to help but still not enough.

So to help out with this problem, since you can rotate the flash head, you can bounce the flash off the ceiling or walls, if they’re white, the light will remain clean, But you might catch some colour if you bounce it off a coloured surface. So lets try bouncing the flash.

Bounced off the ceiling.

Bounced off a Coloured Surface
As you can see by bouncing the flash off of a surface you cut out a lot of the back shadow, or at least soften it or change the direction it is cast. Bouncing is always a cheap option and in a pinch can work really well, I use bounce a lot when working in casual environments, it avoids blasting the person in the face with all the light energy, which also would cause them to blink, and of course the deadly red eye (yes, red-eye reduction mode, but I never use that). The problem with bouncing the flash is that it will prevent light from striking certain parts of the subject, loosing those parts in the shadow. As you can see with the shot where the light was bounced off the ceiling the lower parts of the subject are dark and in shadow. With the two bounced off the walls, the side that the light wasn’t coming from was dark, and in the shot where I bounced the light off a blue surface, there is a colour cast to the light. Of course all of these can be defeated by using a device called a reflector, but not everyone has this in their inventory, plus that’s getting into a little more advanced things.
So the next step is to combine diffusing and bouncing, Gary Fong released a cool device called a lightsphere, but you can do the same thing with a frosted plastic beer cup, or there are other options out there. I use the lightsphere simply because it was given to me and I like the way it works. How these devices work is that they first diffuse the light using a huge surface area, then blast the light all around the room bouncing it off every surface, and because the device are symmetrical, no matter how you align it, the bounce will be the same.

So as you can see with the lightsphere type device, you get a very even light and very little, if not any shadow at all. For the most part when I don’t have the space to use off camera flash, I’ll use a lightsphere because it gives you the same type of light that you’d get from a studio setup, without having an entire studio with you.
You would use a flash when the area is too better light up your shot, but if you’re outside, would you still use a flash? Well the answer is yes, as you can see with some of the shots you have fairly directional light which does cast shadows, when you’re outside your directional light is the sun, and especially on sunny days you can get a lot of shadow cast on your subject, so a flash mounted on your camera can help as “Fill Flash” filling in light where it’s needed. Most modern units are intelligent enough to use the camera meter to put out enough light energy on the subject as to not wash out their features, but to just nicely light up the darker areas.

For example in this shot, I was able to use the flash to overcome the strong backlighting, so that the girl wouldn’t just be a silhouette.
I know, I did not touch on using studio lights and other special modifiers, as that is a more advanced subject than the basics, and that will come in a later post. Keep shooting!
