Eye-Fi is a wireless memory card for digital cameras. Once you get it set up, you take a photo with your camera and it's automatically uploaded to your computer and to Flickr (or another photo sharing site of your choosing). The first thing you notice about the Eye-Fi is that it looks just like an ordinary 2-gig SD card...so tiny that when you use it for the first time, you almost can't help but examine your camera from all angles to make certain that there are no wires involved. It's magic.
But can an enchanted memory card make you a better photographer? That is, does it make you want to use your camera more and take better pictures? I've been testing an Eye-Fi for the past week, courtesy of my friends at Photojojo (where every order comes with a Blow Pop!). The setup and usage were pretty easy. Not having to fuss with an uploading cord was nice. I didn't like the requirement of setting up each wireless connection you want the card to use; it should find open wireless access points when it can. But after a week of using the card, I finally figured out the optimal way to use the Eye-Fi:
1. Get a Flickr account.
2. Set the Eye-Fi to upload automatically to your Flickr account with the privacy set so that only you can see it.
3. Use Flickr's online organization tools to publish, group, tag, or order prints of the keepers and discard/ignore the rest.
Instant online-only workflow...no intermediate "download then find the best ones then upload" steps required, everything happens right in Flickr. The lack of editing tools (brightness, levels, etc.) on Flickr might be a deal breaker for some, but for the rest, it certainly makes it easier to take a lot of photographs and get them up where family and friends can see them.
