Light rays which are reflected by any surface become polarised and Polarising filters are used to select which light rays enter your camera lens. PL (Linear Polarising) and PL-CIR (Circular Polarising) filters have the same effect, but it is important you choose the correct version for your camera?. They allow you to remove unwanted reflections from non-metallic surfaces such as water, glass etc. They also eneable colours to become more saturated
These popular filters are renowned for their ability to minimise reflection at the filter surfaces which reduces glare and ghosting. The result is an average light transmission of over 97% giving sharp contrast and well balanced colour. Hoya HMC filters are recommended for enhancing the performance of today’s multicoated lenses.This 80B filter increases the colour temperature from 3400?K to 5500?K for the use of photoflood lamps.
Increases contrast between reds and yellows. Particularly useful for distant outdoor shots taken with a telephoto lens. Also useful in colour photography for spectacular sunsets, seascapes, etc.
Acrylic filters similar to half-colour, except that colour density gradually decreases near the centre of the filter allowing emphasis of foregrounds or backgrounds.
Especially useful for clear contrast between blue sky and foreground. Provides natural tonal rendition. Often used for subjects at intermediate distances.
Especially effective for increasing contrast. Ideal for dramatic cloud effects in landscapes. Can also be applied creatively in colour and infrared photography.
Used primarily for black and white photography, the Yellow/Green filter is highly effective for outdoor portraits because red is rendered dark green while gren appears lighter.Great for correcting skintones, bringing out facial expressions in close-ups and emphasising the feeling of liveliness.
Especially useful for clear contrast between blue sky and foreground. Provides natural tonal rendition. Often used for subjects at intermediate distances.
Neutral Density filters (ND) filters are often ignored by photographers, but they have several uses and offer the the possibility to achieve otherwise unacheivable results. ND filters appear grey and reduce the amount of light reaching the film, they have no affect on colour balance. They have 4 main uses:i) To eneable low shutter speeds to be used, especially with fast films, to record movement in subjects such as waterfalls, clouds, car
