ZeroImage Exposure Scale

The aperture (f/stop) of pinhole camera is always larger than f/90, even if you have an expensive professional light meter, it can't show you the exposure time. ZeroImage designed this special exposure scale for you, it is easy to get the exposure time. (It is still necessary to use a light meter to get the reading of the scene firstly.) The scale is made of 0.5 mm brass. The numbers on the larger dial are the exposure time range from 1/8000 of a second to 15 hours. The numbers on the smaller dial indicate f/stop number setting range from f1.4 to f/500. This special designed exposure scale comes with a lanyard to allow you to wear it around the neck, keeping it both handy and secure. It also comes with a key ring (not shown in the picture) for you to carry the scale as key holder. Or you can install the scale to your pinhole camera. Installation of the scale is easy, what you need is only a 2.5 drill bit and some glue. Locate the scale and fix it with the provided screws. All ZeroImage cameras come with the exposure scale pre-installed (without lanyard and key ring) except the Zero 4x5 system which comes with a larger paper version exposure scale. You don't need to buy this accessories if you purchase the ZeroImage Zero 2000, Zero 135, Zero 6x9 or the Zero 612F. Instruction guide for installation will be provided if you purchase the scale alone.
