EXPOSURE SLIDING SCALES

Don't be afraid of the dark. Behold the Black Cat, which goes where regular light meters fear to tread.
No power is required for one of the most advanced handheld exposure calculators available. Merely swing the dial to the appropriate ratio and you will immediately have a wide variety of exposure combinations at your fingertips. While low-light exposures will always fool a traditional light meter, the Black Cat has excellent night time vision. Get yours for only $19.99.

This is one Black Cat that isn't bad luck.
