PrimeCircle filters are diamond cut from German Ultra-White optical glass, the best quality solution for modern high resolution lenses! The parallel relationship between front and rear surfaces (important for the best optical performance) is verified with a laser interferometer and a densitometer is used for testing consistent density. To check proper light transmission is also used a spectrophotometer!
PrimeCircle Neutral Density (ND) Grads can be used
to balance exposure in uneven lighting situations
or to increase color saturation in sky scenes, by lowering
sky exposure. PrimeCircle makes both soft-edge and
hard-edge Graduated filters.
Typically soft-edge filters are used with wide to medium-angle
lenses because these lenses have greater depth of field.
Hard-edge filters are preferred for use with telephoto lenses
or for bold transitions. Generally used also to compensate
extreme contrast in several shooting situations.
