    98== Global usage ==
     
    1110''TODO''
    1211
    13 == Delays ==
     12== Geometric head setup ==
    1413
    15 There are two delays to set in the configuration dialog: ''Stabilization delay'' and ''Time value''.
     14When the Merlin/Orion head is turned on, its internal electronic sets the position of both axis to zero. Be aware that in preset mode, the pitch axis positions assume that the zero is the position where the camera is horizontal; if it is not the case, zenith/nadir won't be real zenith/nadir.
    1615
    17 The first one is the delay between the end of the move end the effective shooting. Depending of the tripod used, the head can start shaking while moving. So, it maye need a long delay before it stabilizes again. This is especially true if the head is on a long pole.
     16In order to set a correct zero, you should first put the yaw axis so the camera is horizontal, using a bubble level in the flash connector, and then press the ''Home'' button, to tell Papywizard to use that position as origin.
    1817
    19 The second delay mainly depends of the exposure time of the camera; it should be longer that this time. Take into account the total time of the shooting cycle, which is longer that the exposure time alone. Note that the shutter trigger remains on during all the ''Time value''; if the camera AF mode is on, use a much longer delay to let it complete its AF cycle.

    21 == Bracketing and mirror lock-up ==
     20In the shooting sequence, Papywizard will do the following steps:
    2221
    23 Panoramic shooting often needs to use bracketing, especially for full-spherical panos. Papywizard supports this feature: just enter how many pictures your want to take at each position with the ''Number of pictures'' config. parameter.
     22 * move to the requested position
     23 * wait '''stabilizationDelay''' sec.
     24 * if '''mirror lockup''' flag is set, trigger the camera shutter for '''stabilizationDelay''' sec.
     25 * trigger the camera shutter for '''timeValue''' sec.
     26 * move to the next position
    2427
    25 If you want to lock-up the mirror before shooting, you can also use this parameter. Set it to 2 if you want only 1 shot, or 6 if you want to braket on 3 exposures with mirror lock-up at each shot.
     28The '''stabilizationDelay''' value mainly depends of the camera/lens weight, and the size of the tripod. Using heavy camera and small tripod will take longer to stabilize than light camera and strong tripod. In practice, 0.1 to 0.5 sec. should be enough.
     29
     30The '''timeValue''' param should be computed so that the entire shooting sequence can complete. This includes:
     31
     32 * AF cycle
     33 * if '''mirror lockup''' flag is not set, time for mirror to lockup
     34 * exposure time
     35 * time for mirror to go back to initial position
     36 * time for writing buffer image to card
     37
     38The last 2 sequences can be included in the next move, but be sure that the camera is ready when the next shoot sequence begins!
    2639
    2740== Shooting direction ==
     
    3043
    3144The best configuration mainly depends of the subject you are shooting. For example, if you have fast moving clouds, it is best to let the default configuration, to shoot the entire sky as fast as possible. But it also depends of the orientation of the head; if it is mounted on an horizontal pole, then choose column as first shooting direction.
    32 
    33 == Home position ==
    34 
    35 When the Merlin/Orion head is turned on, its internal electronic sets the position of both axis to zero. Be aware that in preset mode, the pitch axis positions assume that the zero is the position where the camera is horizontal; if it is not the case, zenith/nadir won't be real zenith/nadir.
    36 
    37 In order to set a correct zero, you should first put the yaw axis so the camera is horizontal, using a bubble level in the flash connector, and then press the ''Home'' button, to tell Papywizard to use that position as origin.
