Chris wants to talk about the technology of a digital camera. Every DSLR camera has a bump on it and that houses the penta-prism or penta-mirror. The electronic viewfinder is also in there. Why does an electronic camera still have a mirror? Well, mirrorless cameras don't have the mirror array, but they do have a viewfinder. A DSLR needs one to bounce the image in order for you to see the image, and the prism makes sure it shows up right side up. When it's mirrorless, then the camera doesn't need to reflect any image, it just broadcasts it to an electronic viewfinder.

Chris Marquardt: Through the Round Lens

The topic for today's Photo segment is why lenses are round and not rectangular like the images. Chris says that a lens is essentially a projector, and all projectors cast a circular image. What makes the image square is the sensor, though the original Kodak actually printed round images. It's also better to have round lenses because round motion can convert to linear motion more easily.

Chris is just finishing up a book on Wide Angle Photography. The human eye is roughly 180 degrees from one edge of the human eye to another. A shorter focal length than 50mm is considered wide angle. The larger the number in mm, the narrower the angle. The thing about wide angle is that you have the advantage of being able to include more information in the image. They're great for portraits and landscapes. But the downside is, the wider the angle, the more distorted the image will look. Suddenly your subject's head will look larger, or features on their face will become exaggerated.

Gear acquisition syndrome (GAS) is a common malady with photographers who think that upgrading their gear or getting more gear will make them better photographers. It's not really the case, usually. But Chris says that getting better gear can help by expanding the toolset you can use to take pictures. As long as you actually use them. But often, a trip will trigger GAS in them.

Today's topic is shooting a solar eclipse. There's an eclipse coming in a few weeks (Aug. 21) and Chris has a few tips on how to shoot them:

Chris joins us this week to talk about street photography. Chris says that using a long lens is a great way to shoot street photography because it gives a buffer to be able to take pictures without violating anyone's privacy. Chris also says if you're not afraid to ask them, a 50mm is better. 25mm for micro four thirds. That's because you're not too far away and it makes the whole scene look natural and feels like you're there. Zoomed shots look like a spy photo. They're flat and compressed. By contrast, wide angle lenses look distorted and strange.

Chris is here to talk about wide angle photography. Using a wide angle lens is challenging because it can often disappoint the photographer. A wide angle lens is below 50mm. The smaller the MM, the wider the angle. The wider it is, the more stuff you have in the picture and that means more things that compete with each other. The reason why is that wide angle isn't how we as people see the world, so it's hard to compose. But that's a good thing because it forces you to work on your composition, rather than take it for granted.
