Camera app alternatives, like ProCamera, offer experienced photographers more control when shooting with an iPhone.
iOS's built-in Camera app is a useful piece of software, enabling the most rank amateur to take a well-exposed photo under a variety of less-than-ideal situations. At the same time, we have lamented on several occasions that Apple's built-in Camera app leaves a lot of room for improvement when it comes to advanced controls. While Apple's approach favors "tap and snap" simplicity, experienced photographers often want more control.
That added control is exactly what some third-party iOS photo apps aim to offer. We decided to take a quick look at six such apps for those looking for a Camera app alternative for your iPhone photography: 645 Pro ($2.99), Camera Awesome (free), Camera+ ($1.99), Camera Plus Pro ($1.99), Pocket Camera Pro ($0.99), and ProCamera ($2.99). Each app has a unique take on the interface, and most tend to offer similar features, as it appears that full manual control over the iPhone camera hardware isn't exposed to developers via official APIs. That said, you might find one of these apps suits your shooting style better than the Camera app.
645 Pro is definitely trying to woo photographers more accustomed to finely crafted mechanical cameras such as the Hasselblad 500c, Pentax 67, or Mamiya 645. Its name comes from the 6×4.5cm medium format size, which has the same proportions (4:3) as the iPhone's camera sensor. A dial allows the user to choose from common medium format sizes, including 6×6 (1:1), 6×7+ (4:5), 6×9 (3:2, same as 35mm), and 6×12 as well as 6×17 panorama formats.
