Cambox – camera to Dropbox ($0.99) by fichek is a camera app that allows you to link your iPhone’s camera with Dropbox, automatically uploading your snapshots so that you can access them on all of your devices and computers.
Opening the app takes you directly into a camera that you can use to take photographs. Once you’ve taken a photograph, it prompts you to connect the app to your Dropbox account, adding a new Cambox folder.
When the app is connected to Dropbox (you only need to do it once) each photograph that you take will be automatically uploaded to your account over 3G or Wi-Fi, which takes just a few seconds.
You can wait for a photo to upload, but if you exit the app it will still upload, which is quite handy.
Unfortunately, while the Dropbox connectivity is great, the camera itself is disappointing. You can tap to focus, switch between the back camera and the front facing camera, and turn the flash on and off, but that’s it.
There’s no zooming, no photo filters, no cropping, and no red eye reduction. There’s no functionality that would allow this to replace your main camera app, unless you need a simple photo with no retouching.
You can, however, set it to upload only while connected to Wi-Fi, and you can choose the photo quality. You can also prevent the app from saving photos to the camera roll on your phone.
When I first saw this app I was hoping that I might also be able to upload or sync photos from my camera roll automatically to Dropbox, but that is not possible. It is only able to upload photos taken directly with the app, which means your Instagram, Hipstamatic, Camera+ and Snapseed photos cannot be used in conjunction with Cambox.
As someone who regularly uses those apps to take photos, I found that Cambox was not practical for me, but if you like photos straight from the camera with no retouching, this is a viable choice to get your photos to Dropbox quickly.
