Important: Keep the camera as still as possible while shooting all the frames or use a tripod to hold it.

Camera modes

HDR mode

In HDR mode the camera captures three successive frames at different exposure levels and fuse them together in order to produce a high dynamic range image.

Bracketing mode

In this mode the frames at different exposure levels are captured but not processed. This is useful when you plan to fuse them later using for example the application provided by us for desktop computers.

Single shot mode

This mode is similar to the classic camera application and it includes advanced features such as pinch to zoom exposure point and locked focus.

Keep the camera as still as possible while shooting all the frames or use a tripod to hold it. Before processing images at high resolution it is recommended to close all other background applications.

Top buttons

Enable the camera flash when there is not enough ambient light. The flash is triggered on the last frame.

The images fuse process can be skipped. In this case only the bracketed frames will be captured and saved. An HDR image can be produced at a later time using Fuse Images menu option or an external (desktop) application. Such an application is available at no additional cost at: www.hdrphotocamera.com.

Tip: When noticing large or intense grey areas in the fused HDR image, reducing the exposure difference between the over exposed frame and the under exposed one will usually help obtaining better results.

Focus

When pressing the on-screen camera button or after a full press on the hardware button the camera will automatically focus before taking the pictures.
In order to manually focus you must press the hardware camera button half way down and hold it until the green rectangle is displayed in the middle of the view finder, then continue to press the button to take the pictures.

Exposure levels

You can adjust exposure levels for each frame before taking the pictures. When doing this an on-screen preview will help choosing the best value. By default the first frame is over exposed (+2.5), the second one is normally exposed (+0) and the last one is under exposed (-2.5). In general you need to over expose the first frame until dark areas in the scene are visible and under expose the last frame until there is no glow on the bright areas. Too much over exposed or too much under exposed frames may result in poor image alignment or artifacts (dark-bright gradients) in the fused HDR image, in such special cases using a tripod and adapting fuse parameters might be necessary.

Fuse settings

There are three fuse parameters Contrast, Saturation and Exposedness (well-exposedness), with default values of 1, 1 and 5 respectively. When setting any of the parameters on 0 the corresponding characteristic will not be taken into consideration in the fuse process.

Advanced settings

Although not recommended the bracketing speed can be customized. The default value, Medium, is adequate for almost all situations. Quick option can be selected for very bright scenes with slow moving objects (e.g.: clouds). This will reduce ghost effects. Slow option can be useful in very dark scenes. Still, you should note that fully dark scenes can not be over exposed and using the flash is sometimes the only available solution.

Fuse Images

Images can be fused with different parameters. Pressing fuse button multiple times, for already fused frames, will result in multiple versions for the same HDR file (e.g.: Img251HDR.jpg, Img251HDR(1).jpg, Img251HDR(2).jpg ...).
