Optical Fundamentals

Testing the limits of any lens we get our hands on is both fun and instructive. Sometimes you can stumble upon unexpectedly delightful discoveries. In the previous review, we tried …

We’re after some experimental fun today 🙂 As they say, the best way to learn something is to try it yourself. Back in high school physics we had a unit …

I remember the very first post I published on this site—I’d written about how I missed the shots I used to take in macro mode with my old compact camera. …

Long ago I read an article by master John Hallmen whose original Swedish title was “Att tämja blixten.” It meant “taming the light” and contained many tips on using flash. …
