The iPhone's built-in Camera app is made to be simple to use but the main problem is that if you’re a more advanced photographer, this simplicity can sometimes drive you up the wall.
It won't let you easily adjust white balance, for example, nor will it allow you to choose slower shutter speeds or adjust the ISO manually.
Thankfully, a lot of third party providers have long stepped up to the plate and offered apps that do let you control these parameters in the iPhone.
One of these apps is ProCam 4, a US$4.99 (about RM22) app that does allow you to take control of many of the settings in the iPhone's camera such as white balance, ISO and shutter speed.
In fact, since iOS 10 was introduced, ProCam 4 now can capture images in RAW format for iPhones that have the newer 12-megapixel image sensors (that currently means the iPhone 6s and up).
RAW files are the so-called “digital negative” – it captures much more data than a compressed JPEG image and thus allows you greater control of the final photo by allowing you to regain detail lost in bright or dark areas when using RAW editing software like Adobe Photoshop or Lightroom.
We’ve been testing ProCam 4 for awhile now and we must say the app has an extensive feature list and it’s all quite straightforward to understand and use.
Apart from saving files in Adobe’s DNG RAW format and allowing you to control white balance, shutter speeds and ISO, ProCam 4 allows you to manually focus the iPhone’s camera and even has focus peaking which highlights in-focus areas in red.
On the iPhone 7 Plus, ProCam 4 even allows you to switch between the wide-angle lens and the short telephoto lens.
The app also has some extensive editing options including a range of photo filters and special effects overlays (such as a tilt shift effect) and you can even extract 6-megapixel still images from 4K video that you’ve shot, or 8-megapixel stills if you use the Advanced Upscaling option.
