Flash and Glass
If you find yourself in a situation where you want to use your flash to shoot through a window or display case, try placing your lens right against the glass so that the reflection of the flash won’t be visible in your image. This is extremely useful in museums and aquariums.
A Few Words About External Flash
We have discussed several ways to get control over the built-in pop-up flash on the D7000. The reality is that, as flashes go, it will only render average results. For people photography, it is probably one of the most unflattering light sources that you could ever use. This isn’t because the flash isn’t good—it’s actually very sophisticated for its size. The problem is that light should come from any direction besides the camera to best flatter a human subject. When the light emanates from directly above the lens, it gives the effect of becoming a photocopier. Imagine putting your face down on a scanner: The result would be a flatly lit, featureless photo.
To really make your flash photography come alive with possibilities, you should consider buying an external flash such as the Nikon SB700 AF Speedlight. The SB700 has a swiveling flash head, more power, and communicates with the camera and the TTL system to deliver balanced flash exposures.
