Tired of your digital photos coming out in all the wrong colors? The baLens lens cap's translucent plastic dome lets light through, allowing you to perfectly set the camera's white balance while the cap is still on. Other than that handy feature, it works just like any other lens cap. Available in a variety of sizes, each $54.95 cap includes easily interchangeable domes for both neutral and warm colors.

Judging from the green, yellow or red-tinged look of some of my recent photography using my camera's automatic white balance, I could use one of these. And, there's no need to carry around yet another camera accessory, because this baby is always sitting right there on the end of the lens. Plus, it looks kinda cool, too. Excellent idea!
