Ever wonder just how much light a polarizer filter cuts out from your photos? You can easily see the effect in the viewfinder as your turn the filter and see the reflections disappear, but what if you could take a photo of the light it cuts out?
Sounds impossible? Not if you use math… and Photoshop.
Question: What’s the only (non-gimmicky) photographic filter that can’t be duplicated in software? That’s right, you smart genius you! It’s the polarizer. A polarizer will do two things for your photography: it’ll increase the saturation of the colors in your pictures, and it’ll cut out unwanted reflections from glass and water. And Photojojo will now sell you one that’ll clip right onto your iPhone.
Got a set of those annoying lenses for your iPhone that attach via magnets? Me too. The results are great, but getting the magnets lined up to the metal donut surrounding the lens is a real pain.
And so the following news is mixed. It's bad news because it uses the same dumb attachment system, and it's good news because it's a polarizer for the iPhone. And not just any polarizer, either. This one is made by legendary filter-monger B+W.
