Introduction
Camera FV-5 is an advanced camera application for Android devices. Currently it runs on mobile phones, tablet computers and Android-powered cameras. It brings the camera control typical from advanced point&shoot and DSLR cameras, control that is missing from stock firmware and OEM camera applications. It squeezes every ounce of your camera by providing a unique hardware abstraction layer that it is able to control camera modules of more than 2000 phones, tablets and standalone cameras. All devices are supported by the same application. Given the big differences among all the devices Camera FV-5 is able to run on, the controllability of those devices also varies significantly. This is discussed through this manual.
Tailored to enthusiast and professional photographers, with this camera application you can capture the best unprocessed photographs so that you can post-process them later with as much quality as possible and get stunning results. The only limit is your imagination and creativity!

Getting Camera FV-5
Camera FV-5 is available through Google Play, the marketplace for Android applications. Google Play is preinstalled on all Android devices. You can find Camera FV-5 on the top positions of the “Photography” section, as well as searching for “Camera FV-5”.
There are two versions of Camera FV-5: Camera FV-5 Lite and Camera FV-5 (paid version). Both versions are essentially the same, with the only difference being the resolution limitation on the free Lite version. Therefore you can try the application without any time limitations and see if the application works properly and fits your demands before buying the full paid application.

Regardless of the version of the application you download, you have access to frequent downloads. You get those updates by either manual download (you get notifications on the Android notification drawer when updates become available) or automatically if you decided to do so. It is recommended that you select automatic application updates. You always get the most stable version and newer features without having to care to download updates manually. After each update, a dialog will
tell you what’s new on the updated version (new features, bug fixes and
improvements). Application updates are also free once bought the paid version as well. Therefore, buying the application is a one-time payment, granting you access to all future updates at no extra cost.
Furthermore, when you buy the application, you can install Camera FV-5 on all your Android-powered devices at no extra cost. To do that, be sure to always download the application using the same account you used for buying it on the first place. On that
case, you won’t be prompted to pay again each time you install the application on the
same or other devices you might own.

Obtaining support
For any problem related to Camera FV-5, you can contact to the support team via e-mail: support@camerafv5.com.
If you require help with photographic-related concepts, there are many resources online for general photographic concepts as well as tips, suggestions and techniques. One of my favorites is
Cambridge In Colour
(http://www.cambridgeincolour.com/). It contains multiple tutorials in many categories that go from basic photographic concepts to advanced techniques, and from the camera to the computer techniques to edit the photographs. It is a very worth read!

Basic commands
Camera FV-5 puts all the controls and options —that you would typically find on dedicated physical buttons on a high-end DSLR camera— directly on the screen. Adjusting the ISO, the metering mode or the white balance is just a tap away. All the controls are located around the viewfinder.

Shutter button
Located on the right of the viewfinder, is the virtual counterpart of the shutter button on traditional cameras. It can replicate all the functionality of a physical shutter button. However, if your device has a physical shutter button, you can also use it to take photos.
Virtual shutter button
The virtual shutter button emulates a physical shutter button. Since the virtual shutter button cannot react to half-presses like physical two-stepped buttons, the normal operation —tapping on the virtual button— always takes a picture. However, the default behavior is to trigger autofocus, and then take the picture (that is, the picture is not taken immediately but only after the focus has been acquired).
There are two settings to override this behavior:

Exposure
time
ISO

The normal behavior is to cancel the action of taking a picture if the
autofocus result was unsuccessful (that is, the autofocus routine
didn’t achieve a sharp subject or couldn’t locate the focus position,
both situations lead to a red focus rectangle). If you want Camera FV-5 to take a picture in any case (whether the focus succeeded or not), activate the option
Settings > General camera settings > Allow
taking a photo without focus
.
If you simply don’t want to trigger autofocus before taking a picture
(that is, you want to take a picture without changing the focus position), activate the option
Settings > General camera settings >
Focus before capturing
.
Note If the focusing routine fails, the default behavior is not to take the photo. The focus rectangle turns into red in this case. You can change this behavior in
Settings > General camera settings > Allow taking a photo without focus
although it is discouraged, as the resulting photo could be incorrectly focused.
Physical shutter button
If your phone has a physical shutter key, you can use it to take photos with Camera FV-5. Save for the zoom (when not assigned to volume keys) and any other manual controls, you can take photos without having to ever use the touch screen.
There are two types of shutter keys:
With two steps. Those shutter keys have two depths: you can press
it slightly until the middle (half-press) and then continue until the end (full-press). When you half-press the shutter key, Camera FV-5 focuses the picture and then locks the focus, meaning that you can reframe your shot and the focus distance will remain. When you finally fully-press the shutter key, the picture is taken.
With one step. On that case, the physical shutter key will behave
the same way as the virtual shutter button.
Main photographic controls
The main photographic controls —exposure compensation (EV), ISO, light metering mode, focus mode and white balance (WB)— are always available at the bottom of the screen. Changing those parameters is a breeze: they are

just two taps away, and you always get a preview of the effects reflected on the viewfinder.

Tip You can reset altered photographic parameters to their defaults by long­pressing on their corresponding buttons. The device will produce a short vibration to confirm that the setting was reset to its default and the icons will also reflect the change. White balance is reset to AWB, focus mode to AF, metering mode to matrix, ISO to Auto and exposure compensation to +/- 0.
Exposure compensation (EV)
Adjust the compensation of the exposure time. A value of +1 effectively doubles the exposure time, whereas a value -1 halves the exposure time. The EV range and step vary across devices. A range of [-2, 2] and a step of ½ stop is typical. If exposure bracketing (BRK) is enabled, the exposure compensation will compensate the bracketing exposures, and the bracketing number of pictures and step will limit the EV range. Read more on this on chapter
Automatic exposure bracketing
(p. 34).
Sensor sensibility (ISO)
Select the ISO value: automatic (AUTO) or in the range from ISO 50 to ISO 3200, depending on the device (some sensitivities may not be available, or may take no effect if Camera FV-5 is unable to detect the available ISO range of your device).
Light metering modes
Select which zones to use from the picture to meter light. The available options are:
Matrix. Use all zones to meter light.
Center. Use the central part of the picture to meter light.
Point. Use the focus area to meter light.

Touch metering. Allows you to select the metering point from any point on the picture. This option is only available on devices whose camera hardware supports this feature. The metering point is chosen by long-pressing on the viewfinder. Then, a metering rectangle will appear. This rectangle can be dragged around the viewfinder with the finger once is placed on a specific position. You can reset the metering mode by selecting any of the other metering modes (matrix, center or point).
Auto-exposure lock. Stops the automatic exposure algorithm, keeping the last automatic exposure time calculated while the lock is active. Tap the toggle again to unlock. Supported only on Android 4+ devices with the appropriate support from the camera hardware.
Focus mode
You can choose from one of the following focus modes, plus a focus lock switch.
Autofocus. Focus anywhere on the picture. Focus priority depends on camera maker. Tap anywhere on the viewfinder to trigger AF.
Macro. Gives AF system a hint to prioritize closer objects. On some devices, effectively lowers the allowed minimum focusing distance.
Touch focus. Gives AF system a hint to focus on the selected object. Tap anywhere on the viewfinder to select the focus point and trigger AF. Touch focus, under Android 2.x, is only available on some Motorola, HTC and Nvidia camera drivers, plus some Samsung drivers. Android 4.0+ it is always supported.
Infinity. Set the focus to infinity. Tapping on the screen always result in focus confirmation and AF is not triggered.
Autofocus lock. Locks the focus at the current position. Tap the toggle again to unlock.
White balance (WB)
You can compensate white biasing because of different illuminant temperatures. As of now, you can choose from different presets (ordered from warmer to colder temperatures):
Automatic. The camera calculates the temperature of the light source present on the scene and automatically compensates it.
Cloudy.

Note that preset white balance settings depend on device manufacturer support.
On Android 4+ devices you can lock the automatic white balance algorithm.
Auto white balance lock. If the white balance is set to auto, when the toggle is active, the automatic white balance algorithm will stop running, keeping the last calculated scene temperature. Tap again the toggle to unlock it and recalculate the scene color temperature.
Program modes, shooting utilities and flash settings
At the left side of the viewfinder, from top to bottom, the following settings are located:
Program mode. Here you can see the current selected exposure program mode and change it by tapping on it and selecting a new one from the popup menu. Read more on chapter

(p. 31).
Self-timer. Takes pictures after a predefined time
interval. You can tap on this mode to select 2, 5 or 10 seconds delay, as well as to deactivate the self-timer. When the self-timer is active, tapping on either the virtual or physical shutter button takes the picture after the predefined interval. This mode can be useful (but not only) for:
o Taking self-portraits. o Taking photos on a tripod in low light conditions
