The Apple iPad camera connection kit is an invaluable accessory to anyone owning a camera and an iPad.
It is actually 2 adapters, one for your SD card and one for your camera’s USB cable so you can choose which method to use. When you connect via either method, all the photos on your camera or SD card show as thumbnails on your iPad and you choose which ones to import.
I download the photos from my digital camera onto my iPad and then use iPhoto to tweak them if needed – it’s a winning combination. The kit costs £25 from Apple. iPhoto is available on the App Store for £2.99 for the iPad2 and new iPad.
