Nikon makes external flash units that fit into the accessory shoe (“hot shoe”) on top of the D60. The Speedlight SB-400 is a compact flash unit. It fits nicely with the size of the D60. The head of the SB-400 can be rotated upward 90 degrees to point toward the ceiling. This enables the use of bounce-flash. If you're looking for a more powerful flash than the D60's built-in flash the SB-400 is a good option. Nikon also makes larger flash units, the SB-800 and SB-600. These units are larger and are about the same size as the D60 itself. They offer a more powerful flash, custom settings, and the ability to use multiple flash units wirelessly.
