ProCamera is an incredibly important and great camera replacement app for the iPhone. There is also a new iPad version and we have published several tutorials demonstrating the usefulness of this, read those here.
ProCamera for iPhone has just had an important upgrade, it now features a live histogram guide which helps you take better photographs by showing the exposure within the histogram and offering warnings when it senses that the image will be underexposed. There’s also additional fine tuning and bug fixing, separate lock and unlock exposure and focus in Expert Mode, it also runs a lot faster too.
This is a free update, if you have previously downloaded this app, if not you can download it here. It retails for £2.99/£1.99/download.
