Running Multi-Camera from other programs

Overview

Multi-Camera includes an interface library called DSLRRemoteLib.dll which can be used by other applications to control Multi-Camera. Also included is a simple command line application called DSLRRemoteTest.exe which can be used to control Multi-Camera from a command prompt or a batch file. For example a batch file could be written to take a series of photos using different apertures and shutter speeds to bracket the exposure.

Important: Please select "Use legacy app name" in Preferences before using DSLRRemoteLib.dll or DSLRRemoteTest.exe. The libraries will only work if this option is selected so that the program name is displayed as "DSLR Remote Pro Multi-Camera".

DSLRRemoteLib.dll

DSLRRemoteLib.dll is a library that can be used by other programs to control Multi-Camera. It can be found in the main folder where Multi-Camera is installed (usually C:\Program Files\Breezesys\Multi-Camera). Please see the DSLRRemoteTest\ReadMe.txt and DSLRRemoteLib.h files for details.

Files included:

DSLRRemoteTest.exe - compiled console application

DSLRRemoteLib.dll - DLL used by DSLRRemoteTest.exe to interface with Multi-Camera

DSLRRemoteLib.lib - lib for C++ apps to link to the DLL

DSLRRemoteLib.h - header file for C++ applications using the DLL

DSLRRemoteTest - directory containing a VC++ project and source code for DSLRRemoteTest.exe

DSLRRemoteTest.exe

DSLRRemoteTest.exe is a simple command line application that communicates with Multi-Camera and allows the shutter to be released and some of the camera settings to be changed. DSLRRemoteTest.exe and complete source code to build it using Visual C++ .Net can be found in the DSLRRemoteTest folder where Multi-Camera is installed (usually C:\Program Files\Breezesys\Multi-Camera).

To run DSLRRemoteTest.exe first run DSLR Remote Pro and then open a command prompt window and change directory to the Multi-Camera installation folder. The run DSLRRemoteTest.exe -h to get a list of the available commands.

Here is the output from a simple session where the output directory is set and the shutter is released (commands typed in by the user are shown in bold):
