iPhoto, which Apple released along with the new iPad earlier this month, is an instant hit. The newly launched app has got one million users a little over a week after being available on the App Store, reports The Loop. And the number represents only the unique users, not just downloads, the blog adds.

Apple has already made an announcement that the Cupertino giant has sold its one-millionth copy March 21 and with the sale of the $4.99 iPhoto in under 10 days, the company had made almost $5M.

While talking about the app, Apple's senior vice president of Industrial Design Jony Ive in a latest interview mentioned that the iPhoto app we created for the new iPad completely consumes you and you forget you are using an iPad.

iPhoto Features

According to PCMag's lead software and Web applications analyst Michael Muchmore the app is a stunner.

iPhoto, which is already there in the Mac, is the very first version of the photo cataloging and editing and sharing software that has been designed to work on both the iPhone and iPad. The app works exclusively on the iPhone 4 and 4S, the iPad 2 and the latest iPad that run on the iOS 5.1 or later software update.

Apart from the photos taken using the iPad or iPhone camera, the iPhoto app also works with photos that are synced from iTunes, through iCloud, or through the camera connection kit. However, reviews say that syncing through iTunes or iCloud will compress your image size and will also alter the colors.

1. Photo Management and Browsing with iPhoto

iPhoto, the iOS version which includes variety of photo management and editing features, will win hearts of millions of avid photo hobbyists, believes Apple.

Though the iOS version does not sport the Smart Albums feature that is available in the desktop version, yet the app connects to all the photos present at the Photo library of your mobile device. And, the app also sync with Camera Roll and images and videos copied to Photo Stream.

Now with the app all you have to do is some simple touches and there you go - quickly sort through dozens or even hundreds of photos and identify similar photos to compare and select the best. Moreover, the app lets you check out multiple photos side-by-side again to select the best images. You can also resize and reposition scrollable thumbnail grid for optimal browsing in any orientation.

Additionally, the app comes with its own album where you can save all your edited images without overwriting the original in your Photo Library. Choose your favorite photos with a simple tap and save those images in a separate Favorites Album in the app.

2. Editing with iPhoto

Apple's iPhoto app is a great tool for editing your images. Though the app doesn't work like any other third-party photo apps like Instagram and Best Camera, the app rather lets you take the full control in editing an image for correcting or adjusting blue skies, greenery, and skin tones, white balance loupe, color temperature, or lighten, darken, and change saturation, remove red-eye, spot and blemish and much more.

Editing tools include crop, straighten, color adjust, brightness adjust, and saturation controls. What make the editing special for the app are the multi-touch facility along with brushes, auto-enhancing features, Revert button and a Before and After icon to quickly compare the original and edited images.

With the Editor, you have to simply touch and drag on the parts of the image you want to change. For small corrections, you can use the white balance loupe or you can also use Brushes using your fingertip to paint photos. For removing spots and blemishes, use a more powerful Repair brush.

You can even give more professional touches to your images with dozens of beautiful, Apple-designed effects and you just need to pinch and zoom a vignette or tilt-shift filter to focus on a key part of the photo and apply artistic effects to transform your photos into brilliant watercolors. And all this you can do without destructing the original ones and even the edited images and can be modified at any time.

iPhoto saves edits in JPEG format even if the original was a PNG file or some other format.

3. Sharing Images with iPhoto

A new and exciting feature of iPhoto is that now you can share your stories in a whole new way as beautiful photo journals with stunning web pages to share. Journals can be exported to iCloud and iTunes and shared as a slide show on Apple TV.

You can also sort your collection by Album, Photos, or Events.

Moreover, post photos in your iPhoto library to your Facebook, Flickr, and Twitter account and can also stream photos and slideshows to your HDTV over Wi-Fi with Apple TV directly with AirPlay. Also, play slideshows directly from the app or print your photos wirelessly on an AirPrint-enabled printer.
