The Tiffen 95mm Coarse Thread 82C Light Balancing Filter helps to increase the color temperature by 400K in order to cool the image slightly in order to match the color quality of illumination. When using an 82C filter, you will be able to attain 3200K balance when the prevailing light source is 2800K. The cooling effect of this filter requires a 0.6-stop increase in exposure for normal results.

This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and then mounting to precision metal rings.

A: The Sekonic L-308X-U Flashmate Light Meter is only capable of measuring within shutter speeds of 60 seconds to 1/8000.

Q: 8. What is the highest ISO?

A: The highest ISO reading is 8000.

Q: 9. This meter is used for both incident and reflected light metering purposes. I know that all handheld light meters measure incident light, but I don't understand why this meter is needed for reflected light measurements. The camera's built-in light meter is much quicker and easier to use for a reflected reading. What is the purpose of taking a reflected reading from a handheld light meter?

A: Light meters were designed long before there were meters in any cameras; since some people still like to use a hand-held meter, there was no reason to remove a capability that was already built in.

Q: 10. What size are the background for the studio? One is included a white one right?
