Reeflex Pro Camera is the perfect photography app designed for enthusiasts, creatives, and professional photographers. The app provides pro-level DSLR features directly on your iPhone, allowing maximum control over your photo capture.

In this tutorial you’ll learn how to best use each feature which Reeflex Pro Camera has to offer, so that you can propel your iPhone photography to the next level.



Go MANUAL Press on any of the labels (ISO, SS, EV, MF, WB). Use the scroller indicator for selecting the right value.

Go back to AUTO - Double tap on the screen (viewfinder) to reset your settings to automatic mode.

FOCUS and EXPOSURE RETICLES - tap one time on the viewfinder and tap a second time but now using two fingers. The two reticles will be now displayed on your viewfinder. Move the reticles around the screen to select which area of the scene to have in focus and which to have exposed. To lock the selected AF and EF, use one finger to press and hold on the needed reticle. The reticle will turn blue signalling that the camera will now keep the scene in the selected focus or exposure even while pointing the camera in different directions.

LIVE HISTOGRAMS - Available in both luma and RGB, the live histogram allows you to check the overall exposure of your image to obtain the most optimal level of brightness in your scene. The histograms will appear in the top part of the viewfinder, allowing you to monitor "Shadows", "Midtones” and "Highlights". Click on the histogram to switch in between luminosity and RGB modes.

FOCUS PEAKING - Take advantage of the focus peaking feature for nailing manual focus settings over your subject. Focus peaking works by detecting edges of highest contrast in your scene (and therefore most in focus) and highlighting them in a green color. Never miss a sharp shot anymore.

ZEBRA STRIPES - Use the zebra stripes for identifying over or under-exposed regions of your scene. Red and blue striped patterns will appear in your scene, identifying respectively over and underexposed regions. Adjusting the Exposure Value (EV) you will be able to see how those regions change in surface, allowing you to obtain the desired level of details.



ISO - Use a low ISO value for daylight shooting. Ramp up your ISO values in low light conditions. Be careful, high ISO values will lead to additional noise in the image.

SS - Go to slower shutter speeds for low light scenes. Use a tripod to avoid motion blur in your pictures for low shutter speeds.

MF - Use the manual focus option when you want to highlight close subjects or focus on further away objects.

WB - Sometimes the automatic algorithm fails in choosing the correct white balance, resulting in pictures which appear too "blue" or too "yellow". Use the manual white balance correction to get colours as close as possible to what your naked eyes see.




Switching on gridlines in the Reeflex Camera viewfinder will help you when composing your photos. The grid helps you line up elements in your photo to ensure horizons are level and architectural lines are straight. It’s also great for helping you compose a photo according to the Rule of Thirds or Golden Ratio. Another useful composition can be achieved with the squared grid.

To switch on the gridlines, tap the top header Crossed Squared Box icon, next to the Tiltmeter icon then select the needed grid.


The extended timer allows you to set a 3-, 10-, and 20-seconds delay between pressing the shutter button and the photo being taken. This can be useful in a variety of shooting situations.

For example, if you’re using an iPhone tripod and iPhone tripod mount, you can use the timer delay so that you can appear in the photo yourself.

It’s also very helpful when shooting in dark environments with a tripod. Leaving a 10 second delay ensures that the camera will be perfectly still by the time the photo is taken.

To activate the timer, tap the Timer  icon, on the top headbar, right next to the Flash icon.


Sometimes you might want to use the camera’s flash to illuminate a dark subject or brighten up the shadows in a scene. The flash is set as default on automatic. To fully turn on the flash, simply tap the Flash icon (lighting bolt) on the top headbar, left hand-side.

Now select the needed flash function you wish to activate and tap back on the screen (viewfinder). Tap the shutter button to take your photo with the flash.

To turn the flash off, tap the Flash icon on the top headbar and select the crossed out lighting bolt.


The Tiltmeter is a simple graph-like method of showing how straight or level your iPhone is when taking a photo. The Tiltmeter is a fantastic tool for ensuring horizons or other lines in your photo are straight.

Tap the icon, representing an empty square, in the center of the top header, to select the Tiltmeter. You’ll now see a large cross (grey-color) appear in the middle of the screen with two overlapping horizontal lines (white-color), indicating the orientation of the iPhone. Tap again on the top-header icon to disable the Tiltmeter. As you tilt your iPhone, you’ll see the two horizontal lines (white color) move according to your iPhone movement.  

When the horizontal lines align exactly with the Tiltmeter grid (grey cross), the Tiltmeter will turn green and you know that your iPhone is perfectly at level (with some minor tolerance) – so, in line with the horizon. 

To turn off the Tiltmeter, tap again on the Tiltmeter icon – now representing a square with a cross in it, so that the icon shows once again the empty square.


If you want to take a self-portrait photo you’ll need to select the front-facing camera. To switch to the front camera, simply tap the Circular Arrows icon at the top right of the top headbar.

After taking your photo, you can return to the rear-facing camera by tapping the Circular Arrows icon again.




In digital photography, ISO refers to the sensitivity (signal gain) of the camera’s sensor. The lower is the ISO number, the less sensitive the sensor is to the light available in the scene. The correct level of ISO can vary greatly depending on when and where you are shooting.     

For example, if you are shooting in day light, you should use a low ISO value. Contrarily, for shooting indoors or in darker conditions, you should increase your ISO. Even when the overall scene allows the use of a low ISO, you might want to increase you ISO level to be able to increase your shutter speed, capturing a sharp image of a fast-moving subject.

However, in any case, keep in mind that increasing the ISO value also means increasing the noise in your image.


The “shutter speed” refers to the amount of time that the image sensor keeps capturing light from the scene. In the Reeflex camera app, the shutter speed is indicated as a fraction. The lower the denominator, the longer the sensor allows light in. A slower shutter speed is indicated to capture images in low light conditions. However, if the phone is not perfectly still, a slow shutter speed will result in a blurred image. Therefore, we recommend using a tripod for slow shutter speed.

You can use slow shutter speeds to intentionally achieve blur in your image. Increase your shutter speed when you want to freeze a fast-moving subject in your scene.


Attaining a relatively sharp image first comes with proper focal range. Most DSLR shooters capture with autofocus because it’s simple, effective, and reliable. However, having the option to manually focus on a particular subject, or part of a subject, is crucial to finalizing the perfect picture. Manual focus especially comes in handy when the camera can’t quite fix on what part of the frame you need.

The focus slider allows you to manually focus by sliding focal point from near to far. This comes particularly useful when shooting portraits or other subjects in the foreground.


The main goal of white balance is to include the same colors and tones seen by the naked eyes into your digital photos. Most current devices have automatic white balance settings. However, in tricky light conditions, the algorithm gets tricked and your pictures result too “bluish” or “yellowish”. Reeflex camera app allows you to accurately change the temperature of the colors present in your image, to take your pictures to the next level.
