Usage overview

Papywizard is very easy to use, and I hope the GUI is intuitive enough.

The first thing to do is to edit the configuration, to reflect you camera/lens/head/hardware config. Basic settings are the delay to wait after moving (to let the head stop shaking), the delay to wait while shooting (camera Tv value), and the number of pictures to take at each position (bracketing). See below for specific mode settings.

Second, you need to connect to the hardware (Menu Hardware > Connect). If you use the bluetooth driver (default config), you need to enter the correct address of your adapter. Alternatively, you can get a list of all available bluetooth devices arround, and select the correct one.

Then, just move the head either using the big GUI arrows, or using the shortcuts (see below), and set the start/end positions.

Once it is done, just open the shooting dialog and launch the entire process. That's it!

Advanced usage

Papywizard has now 2 modes: Mosaic mode, and Preset mode. The first one is mainly used for partial panos, and is especially designed for hi-res panos, using a large tele-lens. The second one is designed for full-spherical panos, using a wide-lens or a fisheye.

Mosaic mode

The mosaic mode computations are based on the following parameters:

• minimum overlap
• camera orientation
• sensor coef. and ratio
• focal lens

So, these settings must exactly reflect your configuration.

It also needs the start/end positions, which are two opposite corners of the pano you want to shoot. It does not matter which corner you use for start or end, but it will influence the direction the pano will be shot. Note that, depending of the settings, Papywizard can start shooting from the start position, or from the end position. This is usefull to avoid the head to go back to the opposite corner before shooting (which takes time and uses batteries).

It is also possible to choose the initial shooting direction. Using yaw will shoot row by row; using pitch will shoot column by column. Same, the head can go back to the begining of the row (column) before shooting the next one. See Tips and tricks for advices.

Preset mode

This mode is very simple, and does not use any particular settings; it just shoots at all positions defined in the selected template. The only thing to do is to set the home position of the head (zero), which will be the reference for the template positions. In case the camera/lens can't be moved in all positions, it is possible to set some limits, to avoid potential colisions.

Keyboard shortcuts

Papywizard main target is Nokia Internet Tablets, so keyboard shortcuts are dedicated for that plateform (but works fine with normal PC). Here are defined shortcuts:

• In main window:

Nokia	PC	Function
	Right	Turn the head right (Yaw +)
	Left	Turn the head left (Yaw -)
	Up	Move the head up (Pitch +)
	Down	Move the head down (Pitch -)
	Home	Set current position as start position
	End	Set current position as end position
	Return	Open shooting dialog

• In shooting dialog:

Nokia	PC	Function
	Return	Start/pause shooting
	Escape	Stop shooting - Return to main window

• In all dialogs:

Nokia	PC	Function
	F10	Show menu
	-	Standard maemo behaviour
	F6	Toggle fullscreen mode (no more activated)
