Running Multi-Camera from other programs

Top  Previous  Next


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.


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 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):
