With this post we start a series of short tutorials covering all aspects of using CameraPixels app. CameraPixels is the most advanced and adjustable photography app available on iOS and with that flexibility and power comes initial certain complexity in using the app efficiently. We hope that these tutorials will help you utilize the full photographic power of CameraPixels and your iOS devices.

After the installation of CameraPixels, during the first launch you will be asked to grant permissions to the app for it to function properly. Not all permissions are required, but disabling them will limit the functionality of the app. The following permissions are requested during the first launch of CameraPixels:

• Camera – required permission. Disabling this permission will make CameraPixels unusable. The good indication of Camera permission turned off is a black screen of the viewfinder.
• Photos – required permission. Disabling this permission will make it impossible for CameraPixels to store captured photos and videos. The good indication that Photos permission is turned off is the absence of captured media in the camera roll.
• Microphone – semi-required permission. Turning this permission off will make it impossible for CameraPixels to record audio during video capture.

The last permission Location is requested when you activate the Location option in CameraPixels settings. Turning this permission off will prevent CameraPixels from embedding location information into the captured media.

In case you disabled one of the required permissions or simply want to review the state of each permission granted to CameraPixels use the Settings app on your iOS device. In the Settings app scroll down until you see CameraPixels.

Basic elements of the User Interface

CameraPixels has User Interface (UI) with a rather classical layout and should be familiar for most users of other photography apps.

The whole screen can be divided into four distinct areas:

• Top toolbar
• Viewfinder
• Manual settings toolbar
• Capture controls toolbar

Top toolbar

The top toolbar contains controls that are required often enough to be present on screen. For example, you always want to make sure the status of the device flash and output media format to avoid unpleasant surprises. From the top toolbar you can also access the CameraPixels global settings and a grid type.

Pressing a button on the top toolbar will open the corresponding dialog with additional settings, e.g. Flash/ Torch dialog will show available flash and torch modes and when torch is available and active – brightness of the torch light.

Viewfinder

The viewfinder is where live preview of the capturing scene is shown. The viewfinder in CameraPixels is touch sensitive and tapping on it will change focus and exposure points if those are accessible at a given time. The viewfinder supports multiple gestures:

• Single-tap with one finger – change the focus and exposure points
• Single-tap with two fingers – split focus and exposure points
• Press and drag – when the focus and exposure points are split and press performed on top of the corresponding reticle, it can be repositioned independently from the other reticle (you can independently adjust focus and exposure points)
• Double-tap – reset focus and exposure points and set their modes in auto mode

Manual settings toolbar

Manual settings toolbar as its name suggests allows changing manual settings of the camera, e.g. white balance, ISO, or shutter speed.

By default, all settings are in auto-mode and changed by the camera automatically based on the lighting conditions and distance to the subject. If a setting is in manual mode, its value can be changed using a value selector dial.

Capture controls toolbar

To capture a picture or start/stop recording a video, change a capture mode, and adjust its settings, switch between front and back cameras can be done using a capture controls toolbar.

Additional elements of the User Interface

Depending on the CameraPixels settings and device capabilities, there could be additional UI elements present on the screen.

Both histogram and zoom slider are enabled by default and should be visible on the screen unless the feature is not supported by the underlying hardware. The camera selector is available only on dual and triple-camera devices (e.g. iPhone 7 Plus, X, 11 Pro).

Conclusion

In this tutorial we learned what permissions are required for CameraPixels and what limitations will appear in case some of the permissions are turned off. We also had a first look at the user interface of CameraPixels and described the main and some additional elements visible on the screen. In the next tutorial we’ll learn how to setup CameraPixels, choose the language, get access to the Quick User Guide and contact out support.
