Episode 1385

Chris says that the last Sunday in April is World Pinhole Day, which is the simplest way to take a picture. You just need a light tight box with a pinhole in it. Something light sensitive. No Lens. It's called Camera Obscura and today is the day we celebrate it. People make pinhole cameras from anything, including beer cans. The hole gives you a special property ... everything is equally sharp and unsharp at the same time. That gives it a bit of a dreamy look. Everything is also in focus. Solography is photography that uses a pinhole camera to take a picture of the sun.

What camera should I buy?

Sony a7s

Episode 1381

Ronette from Norco, CA

Ronette would like to upgrade her Nikon D3300 and Panasonic Lumix G3 digital cameras. What would be the next level? Leo says that the next step would be to go with a bigger sensor, like full frame. That will give her more dynamic range and the ability to take in more light. Leo says that mirrorless cameras like the Sony A7 could work. They are remarkable, but many photographers prefer the 'through the lens' mirror design. The quality of the images would be the same, so it really comes down to preference.

Are internet enabled security cameras secure?

Episode 1380

Tom from Madison, WI

Tom wants to add a security camera to his home. He wants to know which one to get and how secure they are. Can they be hacked? Leo says that there's a lot of concern over the "internet of things," which includes cameras. They don't get updated very often. Foscam made cameras that were easily hackable, so Leo suggests not getting them. He won't want to get the low end, off brand stuff either. It won't be secure.

Why can't my camera read my SD cards?

Episode 1367

Evelyn from Kenai Peninsula, AL

Evelyn fears she's broken her camera because her SD cards can't be read. Leo suspects that she pulled out the card while it was writing and it damaged the reader in the camera. She may be able to reset the camera, which she can find information for in the manual. That could bring it back to default settings, which could solve the problem. She could also download the firmware for the camera and reflash it.

How can I record my daughter's games on the cheap?

Canon PowerShot ELPH 520

Episode 1357

Ed from Pennsylvania

Ed has a Hi8mm camera with Firewire and he wants to record directly to the computer. Leo says he probably could, but it won't be in hi def. Even his smartphone would be better in quality than that old Hi8 camera. He'd also need a Firewire drive and Firewire is a dead technology. He'd be a lot better off with a point and shoot, and it would give him 12x optical zoom. A Canon ELPH will cost under $120.

Episode 1337

This week's gadget from Dickie D is the Panono Camera. It's a ball with 36 3MP cameras embedded in it and you toss it up in the air and it takes a picture when it reaches the apogee of the arc. It costs $1999.00. It turns out that the units are very difficult to produce and it sounded like they were almost hand making them. When you throw it in the air, be sure you catch it, because they break if they hit the ground hard! That could be why they now sell a special selfie stick, so you can just hold it over your head. That adds another $50 the cost.
