Ten Essential... iPad Apps
Have tablet, will download
Filterstorm is a must-download app if you use your iPad for viewing photos. The app includes a number of basic photo-editing tools, such as the ability to scale, crop or rotate photos, along with more advanced controls for improving image quality. There are hue and saturation controls for adjusting colour balance, sharpening filters, and even luminance curves for people that understand that sort of thing. Adjustments can be made globally, or just applied to specific areas of a photo by using the brush tool. Firestorm is free at the moment, although developer Tai Shimizu plans to charge for it in the future.
There are plenty of PDF readers for the iPhone and iPad, but GoodReader is one of the most popular. The iPad version makes good use of the extra screen size by providing a preview panel so that you can quickly check a file before opening it, along with options for downloading files from the internet or FTP servers. The app can read other types of files too, including MS Office files, photos and videos, and can link in with other apps and services, such as Dropbox or Google Docs, so that you can quickly download and view all your important files.
