---++ Basics

1. Setup the cameras. For best results, adjust each camera and/or the beamsplitter so that the image seen in the camera viewfinders are as lined up as possible. This is simplest if the white guide lines are turned on. Note that one of the images will be reflected. 

2. Adjust the exposures. There is a small knob near the front of the camera. Press and hold this knob to bring up the controls. Twist the knob to highlight "Exposure" and press the knob again to select it. Twisting the knob will now change the exposure level.

3. Set the zoom. Given that we currently have no means of ensuring that the amount of zoom on both cameras will always be identical, zooming all the way in or all the way out is the most accurate zoom setting at present. 

4. Attach the Arduino control to the cameras and place the box over the setup. In the event that the box is unavailable, place some black material directly to the left of the setup. If there is anything between the beamsplitter and the black material, it will show up on the cameras.



---++ Homographic Calibration




---++ !MDA HDR

1. Download the files to your computer and convert them from .MTS files to MDA files.

2. Perform a homographic calibration on the files and stack the MDA files from each camera for easier processing.

3. Run mda-hdr on the stacked files. Command: _mda-hdr brighter.mda darker.mda_ (_mda-hdr-single_ combines individual frames)
