Over the last two years many people wrote to me asking more or less: so which one will work for me? Unfortunately, nobody can tell you that. You have to try and see what works for you.To help find the answer that question more quickly and inexpensively, I recently made available GLARminŸ Tester, a blue light filter test kit, to help you find the optimal blue light filter for your eyes. It has:– 8 blue light filters with different spectral transmission characteristics– a comprehensive table of all marketed blue light filters (with available spectrograms). They are ordered from blocking more blue light to less and grouped based on spectral transmission similarity to the 8 Tester FiltersThe Tester can be worn over prescriptions.Blue light filter Tester S" data-image-caption="" data-medium-file=" data-large-file=" title="Blue light filter Tester S" src=" alt="Blue light filter Tester S" width="300" height="225" srcset=" 300w, 600w, 150w" sizes="(max-width: 300px) 100vw, 300px">Ps: If you found this post 10 blue light filters to relieve computer eye strain, help sleep better, etc. useful, please consider LIKING, REBLOGGING, and/or SHARING it below.↑ Contents ↑

Filters – How to Choose and UsePart 1I think the thing I like most about working in black-and-white is the fact that it’s much more an expression of how I feel about a subject than a representation of “reality.” The world doesn’t exist in Black-and-White (my mother told me that…) so a b/w image is by its very nature an abstraction of the things we see.The judicial use of filters can greatly enhance the impact of how a subject appears, and in black-and-white we can even skew the way colored subjects relate to each other.I normally like to be fairly subtle about my use of filters; a photograph shouldn’t look like a filter was used, just as a print shouldn’t look like it was dodged and burned! One of the most generally popular choices, a #8 Yellow, is usually so subtle that I don’t see much point in using it. Another popular choice, the #25 Red, is often too strong, rendering skies and day-lit shadows illogically dark.My two favorite filters, a #12 Yellow (“minus blue”), and a #23 Red, respectively, have both more strength and finesse than the ones found in most camera bags. The #12 yields an effect almost as strong as a #15 orange, but with only a 1 stop filter factor, only slightly greater than the #8. The #23 tends not to make skies quite so artificially dark as the #25.Understanding the relationships of different colors of light to each other is key to choosing a filter. A standard color-wheel is shown below. The numbers in various color areas are Wratten filter-number designations, an industry standard utilized by many filter manufacturers. A #12 filter, for example is pure yellow, a #8 is a light yellow. The capital letters in bold are called Additive Primary colors, and the lower-case letters are Subtractive Primaries.Red is opposite CyanGreen is opposite MagentaBlue is opposite YellowIn Black-and-White photography the practical effect of a filter is to lighten its own color and darken its opposite color.In purely scientific terms, a filter has no effect on its own color and darkens everything else, including “neutral” colors. When we apply a “filter factor” to the exposure, neutral colors remain unchanged and then the filter’s own color becomes lighter and its opposite becomes darker.What we commonly call a “blue” sky is technically a bit more cyan, which is why a red filter will darken the sky more than a yellow filter. Orange is in between. Keep in mind that outdoor shadows are illuminated by the sky, not the white light of the sun. Any filter that darkens the sky will also darken the shadows!Green or red filters can be quite useful in the Southwest, for example,
