The iPad's journey to becoming more of a content-producing and creative tool took another step forward recently with the release of a new app called Pholium (US$9.99). The app is centered around the creation, viewing, and sharing of iPad photo ebooks.
All of the creation of the photo ebooks is done on the iPad. Whether you're taking images from a camera through the Apple Camera Connection Kit or using photos you took with the iPad's camera, all of your camera roll images are available in the Pholium Gallery. The Gallery lets you bring in Photo Stream images as well, and you can store the pictures that you want to use in your ebook.
Once you have a collection of photos to place in your ebook, you move to the Studio -- a place in the app where images are placed into the book for viewing, arranged or rotated, and text is added. One issue I had with the app is that text can only be added to certain special pages -- when producing photo books with iPhoto, I like to put some captions on images and occasionally write a paragraph or two describing a place shown in the pictures. At least with the 1.0 version of Pholium, you can't do that.
