Polarized Sunglasses – Who Invented Them?

Polarized sunglasses, like many great inventions, are used by many of us without a second thought. But did you ever stop to think about where polarized sunglasses come from? Somebody had to come up with them.

Actually, we owe the creation of polarized sunglasses to four men. In the 1750s, James Ayscough experimented with using tinted glass to correct vision problems.

Many scientists of the time were studying the properties of light and color. In 1808, Etienne-Louis Malus, a French physicist and mathematician, he discovered that light waves from the sun, which usually vibrate in all directions, can be aligned into one direction when it is reflected off something, like water. According to Malus’ law, the intensity of light transmitted through a polarizing filter depends on the angle of the filter in relation to the light.

While Malus’ law is important in the study of optics, it remained for Scottish … Read More

The Immature Photographer

I like to think that I am a bit more mature now. Don’t we all? I’m not sure it is really true, perhaps it’s just a change of perception.

Thinking back, I was very naive and, yes, immature in the past. My first camera was a Zenit E. It weighed a ton but it took photographs. After I had bought it and loaded the film, I set about taking photographs.

I didn’t stray far. No further than my house really. The result was a hundred or so pictures of my cat, the garden vegetation and any human that dared to come near me.

I felt on top of the world. I had made it at last. When, a few months later, I set up a darkroom in my bedroom, I felt that my talents were complete.

Only ther weren’t. because my pictures lacked sparkle and charm. They suffered from overexposure, … Read More

Panasonic Lumix DMC FX40 Review

The Panasonic Lumix DMC FX40 is up against some pretty stiff competition when it comes to pocket sized digital cameras. To try and make the Lumix DMC FX40 stand out from the crowd Panasonic has included an ultra wide angle lens. A wide angle lens helps you squeeze more of a wide scene into a photo. So this could be a big attraction to you if you like to take a lot of sweeping landscape shots or groups of people.

As with other cameras in this series you can increase the amount of zoom available if you are prepared to shoot at lower resolutions. Doing this will save space on the memory card and can also increase the quality of the pictures you take.

Another big attraction aside from the ultra wide zoom lens could be the High Definition movie mode. Although I would not claim that this can fully … Read More
