TAKE A TEST SHOT
Use the self-timer or a remote shutter
release to make an exposure that is free
of vibration. If you are unhappy with the
composition, reset the filter position for a clearer
view, and reframe.

06

ADJUST FOCAL LENGTH

Another strategy for reducing the

aforementioned cross effect is to zoom in

by a few millimetres. Set a 10mm optic to around

14mm for example and reshoot. This helps to reduce

strong vignetting.

05

CHECK FOR UNEVEN DARKENING

At wider focal lengths, a dark cross shape

can appear in the frame centre. Be sure to

review the images and if present, slightly reduce the

filter density from maximum until the darkening

disappears.

SLOW AND EVEN

By predicting uneven brightness effects, it is possible to

adjust the filter to provide dynamic exposures without

unsightly aberrations, characteristic of the filter type.
