Camera+ for both iPhone and iPad have been updated, adding new, Hollywood-themed effects pack, as well as adding effects layering to the iPhone app. Effects layering lets you combine any of the effects of Camera+ to create something new. The Hollywood effects pack includes several new effects and borders. You can try the pack for free, and buy it for $0.99 if you like it.
Additionally, Camera+ has added a couple of widescreen crops, 1.85:1 and 2.39:1. The apps now connect to your Facebook account through iOS native Facebook support as well. Also, if you've purchased an effects pack and have multiple devices that sync Camera+ with iCloud, your in-app purchases will now be synced. The iPhone app update also fixes a bug that caused problems on the new iPod touch that lacks a rear-facing camera. Both updates are currently live in the App Store, so go grab them.
