Carnival of Digital Cameras and Photography is a weekly round-up of all the latest news, trends, digital camera reviews, top blogs, photography tips and professional advice.

Memory Card Backup on the Cheap – DSLRblog has a great post about a way to get a memory card backup/storage device for about $20 (provided you have spare hard disk around).

Failing Hard Drives – Alan Hess has a nice article about failing hard drives and loss of data, as well as a potential solution to avoiding it (the data loss, not the hard drive failure).

Three Point Lighting – Interested in doing portrait work? Stephanie at “i speak film” has a nice post about how to set up three point lighting.

Free Coroplast Grids – Strobist has another great tip for working with light on the cheap. Check out how to turn election signs into a coroplast grid. I think I’m going to do this one.

Nikon’s new D40 – Lots of news of the D40 leak. I’m sure Nikon will sell droves of the thing, but it does nothing to get my heard pumping. Although, I do like news of camera prices dropping.

Microstock Photo – A comparison of Microstock photo agencies was posted at Some Useless Info. If you’re looking to delve into the world of stock photography, a microstock agency might be the way to get your foot in the door.Digital Camera Reviews
