<\/a>Benchmark image, without filter.<\/p>\nNext are cropped sections of the respective images, viewed at 100% in Photoshop the difference between the filters is a little more apparent.<\/p>\n To test the true ability of the filters to block UV light, each filter was placed on a special card with a UV sensitive coating and left in direct sunlight for 5 minutes. The results are below and again some surprises.<\/p>\n As a rough guide, price wise STC and B+W are at the more expensive end, Hoya just below and bargain basement JYC. Conclusions<\/strong><\/p>\n Using the without filter image as the benchmark and in the sequence the images were taken, the results are as follows:<\/p>\n The JYC filter gave a marginal increase in sharpness, there was a slight magenta cast but a loss of contrast. B+W showed a very slight loss of sharpness and a little less contrast. Hoya gave a fractionally sharper image, whilst displaying a slight yellow cast and a small increase in contrast. The STC filter however showed an increase in sharpness across the whole frame giving a very even image, with neutral colour and an increase in contrast.<\/p>\n Since all the filters are described as UV filters, one would expect a fairly even set of results, not so!<\/p>\n The JYC filter blocked hardly any UV light (that filter is heading for the bin) B+W was certainly a surprise, it allowed a noticable amount of UV through, considering the price point of this filter, more was expected of it, both the Hoya and STC blocked all UV light.<\/p>\n Which filters would we purchase? <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n","protected":false},"excerpt":{"rendered":" I know it sound like a strange title for a review of UV (Ultra Violet) filters and since this is generally the first filter most people purchase, it is very valid, as the review will show.
