As with most sophisticated apps, there are several ways to see and do the same thing in iPhoto. Because of that, iPhoto for iOS avoids the pitfalls of some apps that are easy to use but limited in scope and function.

For example, if you have never used a histogram and you do not want to know what that is, you can still achieve the same edit of your image as you would if you were aware that the Exposure slider effectively acts as a histogram. But if you do know that, you will be able to intuit the edit you want more quickly by using the slider to adjust levels the same way you can in iPhoto's Adjust panel.

Tapping directly on the image sometimes brings up on-screen touch controls that correspond to the slider in the menu. For example, the Color control features a menu consisting of Saturation, Blue Skies, Greenery, Skin Tones, and White Balance. You can slide the controls with your fingers to apply changes to a specific part of the image, or you can use the menu controls to adjust the entire image.

iPhoto for iOS has multiple options for sharing photos and albums, and all of them are available via the Share button. The button opens into a pane containing the ten choices you have to show your images or albums to others, including the major social networking tools like Flickr, Twitter, and Facebook. You can also email and print your images, create a slideshow with music that's built into the app, or send photos directly to iTunes on your computer wirelessly or through a wired connection. You can also wirelessly beam your images from one iOS device to another on a shared Wi-Fi connection (or via Bluetooth), and they'll show up in the other device's camera roll. All these functions worked well in my testing. Be sure that both devices have both Wireless Beaming and Include Photo Location on, and are running iPhoto for iOS in the foreground.
