can someone explain this to me?
 

I found this on a beta sp camera's filter wheel:

3200k
5600k + 1/8 ND
5600k
5600k + 1/64 ND

what exactly does this mean?

The 3200 and 5600 are color temperatures measured in degrees Kelvin. Daylight (depending on clouds etc.) is 5600K and tungsten light (Quartz halogen hotlights) is 3200K. If your shooting indoors set the filter wheel to 3200K and then manual white balance. The 5600K has Neutral Density combined in two of the settings. ND reduces the light in bright scenes.

thanks,

ok so shooting outside use 5600k

and then 1/8 ND reduces some light and 1/64ND reduces evem more light? or is it the other way around?

1/8 reduces light on CCD's 8 times, means 3 f-number steps (2^3=8). 1/64 reduces 64 times,means 6 f-number steps (2^6=64)

Never knew those were powers of 2... We learn everyday, thanks!
