Pixelsync is an iPad application that allows you to import images from Aperture and iPhoto to your iPad over your wireless local network using Wi-Fi. All you need to do is turn on your Mac, install a small application, appropriately named Pixelsync Helper, and connect your iPad and your Mac using Pixelsync.
That's not all, though. Once you import your images to your iPad, you can start rating and color labeling your images. When finished, you simply sync this info back to Aperture or iPhoto. This means that you don't have to spend hours and hours in front of your Mac after a day of shooting images. Just get your images in Aperture or iPhoto and import one or more albums or projects to your iPad using Pixelsync and start sorting through your images. We all love our Macs, but sometimes it's more enjoyable to browse your images in your comfy couch. Isn't it?
