Custom Cam

Custom Cam allows you to fully control your iPhone’s camera.
You can switch between full manual mode, automatic shutter speed or ISO mode and full auto mode.
Custom Cam has a 3D Touch shutter button that emulates the half-press of traditional cameras.

Custom cam now supports the iPhone 7+’s second lens!
You can now customise the function buttons by long pressing on them like you would with the icons on your homescreen.

The app also features:

Manual, auto and face detect focus
A very intuitive swipe based system for changing the shutter speed, ISO, focus and exposure compensation.
A light-meter, that anybody who has ever used a camera in manual mode will be familiar with.
Two assignable buttons on screen.
The option to capture as RAW DNG files (on the iPhone 6S, 6S plus, SE, 7 and 7 plus)
The 3D Touch shutter button allows you to lock focus and/or exposure with a half-press.
The half-press is achieved by touching the button, to take a picture simply press deeper.

You can set either of the on-screen buttons to be the 3D Touch shutter button, a focus lock button, a exposure lock button or a traditional shutter button.
Or just turn the second button off for a cleaner ui.

Changing the camera’s settings is done via a set of intuitive swipe gestures, which are very easy to learn.
For example: if your phone is in the landscape orientation, just swipe left or right across the screen on the half which contains the iso label to change the iso value.
A full explanation of all available gestures is found by pressing the in app help button.
