Joining the “Enhanced for iPhone 5″ and optimized for iOS 6 app groups, ProCamera now takes full advantage of the upgraded image capabilities included in Apple’s latest iDevice and mobile OS.

The iSight camera in the iPhone 5 may not have a higher capture resolution, but it does offer other improvements for photographers and videographers. Along with overall, albeit minor, quality upgrades, the new sensor, lens, and iOS developer tools allow for better low-light performance, face detection for video recording, and video stabilization.

In ProCamera v3.8, video stabilization is enabled by default, toggled within the Settings area, whereas Night Capture is easily and quickly enabled or disabled through the live histogram feature. This low-light mode boosts the ISO level to as high as 3,200, which is an increase of four times the previous maximum. In addition to these, those iPhone owners running iOS 6 also have 50 percent faster photo processing and the ability to adjust the JPEG compression percentage.

Unfortunately, the final change is the removal of Volume Trigger, “as requested by Apple.” While the use of the volume buttons for the shutter has been long fought by Tap Tap Tap, Apple’s implementation of the function in iOS 5 seemingly killed the argument, or so one would have thought. In fact, several other third-party apps now contain the feature, including the latest update to Tap Tap Tap’s Camera+. It’s an odd situation that has been the only significant negative response to ProCamera v3.8.

ProCamera is designed for iPhone, fourth and fifth generation iPod touch running iOS 5.0 or later, and available in the App Store for $2.99. Night Capture is an iPhone 5-only feature.
