Getting Started

Sturdy Tripod – All Long Exposure Photography needs to be shot on a Sturdy Tripod using a Smartphone Clamp. You cannot shoot Long Exposure Photography Hand Held.

Manual Mode – Press on any of the Bottom Labels (ISO, SS, MF, WB). Use the scroller indicator for selecting the right value.

Auto Mode – Double Tap on the screen to reset your settings to Automatic Mode. There are no Focus or Exposure Reticles.

Capture Duration – Use the Capture Duration Slider (Right / Left) to set the desired Capture Time for your shot – From seconds, to minutes and hours, up to Bulb (Unlimited). If using Bulb, remember you need to Press the Shutter Button to Close your Capture and Obtain the photo.

Live Histogram

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

Focus Peaking is used for Manual Focus, by detecting edges of highest contrast in your scene and highlighting them in a Green Color.

Zebra Stripes

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 with Shutter Speed and ISO to obtain the desired level of details.

Manual Controls

ISO – Use a Low ISO value for daylight shooting. Ramp up your ISO values in low light conditions. Higher ISO values will lead to additional noise in the image.

SS – Go to Slower Shutter Speeds for Low Light Scenes. Use a Sturdy Tripod to avoid motion blur in your pictures for low shutter speeds.

MF – Use the Manual Focus 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 to get the colors as close as possible.
