+== Tethered shooting ==
+
+It is possible to use an external program to make tethered shooting. The program needs to be run through a shell, where all parameters are given in command-line. If a '''{{{shoot.py}}}''' python script is found in the user config. dir, the 2 functions '''{{{mirrorLockup(stabilizationDelay))}}}''' and '''{{{shoot(bracketNumber)}}}''' will be called instead of internal ones.
+
+Here is an example script which can be used:
+
+{{{
+#!python
+import subprocess
+
+def mirrorLockup(delay):
+    print "Mirror lockup (delay=%.1f)" % delay
+    # See shoot() function
+
+
+def shoot(bracket):
+    print "Shoot (bracket=%d)" % bracket
+
+    # Launch external command
+    #p = subprocess.Popen(["myTetheredShootingProgram", "-capture", "%d" % bracket], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
+    p = subprocess.Popen(["gphoto2", "--help"], stdin=subprocess.PIPE, stdout=subprocess.PIPE)
+
+    # Send data to external command input
+    #p.stdin.write("bla")
+
+    # Wait end of external command execution
+    p.wait()
+
+    # Print external command return code
+    print "returncode=%d" % p.returncode
+
+    # Print external command output
+    print p.stdout.read()
+    #print p.stdout.readlines()
+    #for line in p.stdout:
+        #print line,
+}}}
