Want to view your raw photos in your Dropbox account from your iPhone or iPad? Now you can with Cloud Preview! This app works seamlessly with your Dropbox account and enables you to view all of your images (raw format, jpeg, tiff, png).
Cloud Preview also shows your image exif information and a histogram with intensity, red, green, and blue channels. You can also save your images to your photo library and share them on Facebook and Twitter.
Note: Currently, the maximum image preview size is 6MP. An update enabling full resolution viewing for high memory devices (iPhone5S, iPad 3, iPad 4, and iPad Air) will be released shortly.
