Eye-Fi memory cards are amazing. Tools like Dropbox make them even better!
There is an amazing memory card for cameras called Eye-Fi. It has built-in wireless transfer, so after you take a photo and you enter range of a wireless zone, it just sends your pictures to the storage location of your choice. One clever way to really take advantage is to make that storage destination a folder inside a Dropbox account, or any similar synchronised storage service.
Once the file has been transferred, Dropbox will then sync those files to everywhere else you have Dropbox set up. Even your phone! Suddenly, you can be taking gorgeous pictures with your serious camera, and can have those photos available for sharing on your smartphone just a few moments later.
