The software isn’t just blown up to the iPad’s 9.7-inch canvas, it also comes with new features specific to the iPad version only. Combined with freshly updated Camera+ for iPhone, you can now seamlessly sync your Lightbox between your iPhones and iPads via iCloud. iPad-specific features include new advanced filters, the straightening feature (finally!), brush on effects, layered effects (mix “So Emo” with “Tailfins”) and the ability to import your images from Flickr and Facebook…

The team wrote in a blog post:

We’ve taken parts of Camera+ for iPhone, and completely reimagined, redesigned, and rebuilt others. We’ve created what we believe is the most intuitive, powerful, and beautiful editing experience on the iPad. We thought about everything that makes Camera+ great, and what we would change to have it shine on the iPad.

An optional new feature is iCoud sync as it automatically keeps my Lightbox photos in perfect sync across all of my devices.

Shoot all day on your iPhone, and then edit all night on your iPad. As you take your photos, they will automatically pop-up on your iPad, so you can easily take advantage of the larger screen and advanced editing features of Camera+ for iPad.

Advanced image adjustments include white balance, exposure, brightness, contrast, saturation, sharpness and red eye removal.

Here’s a nice screenshot.

Brush effects can be applied anywhere you want and the app allows for custom brush size, softness and intensity.

Another hugely useful nice-to-have: Camera+ for iPad allows you to layer two or more effects, with each layer having its own intensity.

On the iPad you can brush on (or off) each effect with your finger so you apply it only where you want. You can set the brush size, softness and intensity for ultimate control. So don’t apply your effects to the whole image like an amateur, show some restraint and let your fingers do the talking!
