Filters Glass filters
are made from optical glass, like lenses, and can be multicoated to reduce flare and improve light transmission (to nearly 100% in some cases). They are your first choice for a colourless UV or Protector filter to keep on each lens at all times – it’s a lot cheaper to replace a filter than the front element of a lens!
The popular second choice filter is a polariser. The ‘circular’ polariser refers not to its shape but to the pattern of the light rays after passing through the filter. The technical reason why is unimportant, but the filter is, as it darkens blue skies, reduces reflections off water, and intensifies colours in a way which Photoshop can’t replicate. It’s also good as an emergency neutral density filter.
When do I need a slimline filter?
In general, if you have a lens with a viewing angle wider than 74º (24mm focal length on full frame format) it’s a good idea to go for one. Both the Hoya HD and B+W XS-Pro series have a front thread to take a lens hood.
Resin and graduated filters
Cokin and Lee systems use CR39 optical resin instead of glass (although certain filters in the systems are glass). This material can be dyed to create graduated filters (‘grads’) which are extremely useful in balancing the exposure, for example, of an over-bright sky against a darker foreground. You can achieve a similar result in Photoshop, but it’s way quicker to use a filter at the point of taking the picture.
P System filters are
84mm wide, and Z-Pro System 100mm wide, so they are compatible with Lee and Hitech holders.
