User guide (subversion)

This documentation try to follow the developement version of Papywizard. It may or may not be up-to-date.

For installation instructions, see here.

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 with the GUI arrows, and set the corners position.

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

Advanced usage

Papywizard has 2 shooting 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.

This mode also needs to know two opposite corners of the pano you want to shoot. There are 3 ways to proceed:

• set the corners coordinates from the current position
• give the total field of view for both directions; corners coordinates will be automatically computed arround the Home position (yaw=0, pitch=0)
• give the number of pictures to take for both directions; corners coordinates will also be automatically computed arround the Home position (yaw=0, pitch=0)

Whatever corners you choose to define the pano, you will be able to choose from which corner the head will start shooting.

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).

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 define the home position of the head (origin), 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 (limits are not saved in the current release, so they must be set each time the head is turned on).

Custom presets

Some default presets are provided with the software, but it is possible to add your own. For that, you need to create a xml file which describes them. The file must be named presets.xml and must be in the config directory: ~/.config/papywizard2/ on linux, /home/user/.config/papywizard2/ on maemo, and C:\Documents and settings\<user>\Application Data\papywizard2\¹ on Windows.

¹: you have to configure the Windows Explorater so it shows you system files and directories.

Here is the file structure:

<?xml version="1.0" encoding="utf-8" ?>
<papywizard>
    <preset name="My custom preset">
        <tooltip>
            20D + 50mm
            12 picts @ +55°
            20 picts @ +40°
            50 picts @  10°/-10°
            20 picts @ -40°
            55 picts @ -70°
        </tooltip>
        <shoot>
            <pict yaw="0." pitch="55." />
            <pict yaw="30." pitch="55." />
            <pict yaw="60." pitch="55." />
            <pict yaw="90." pitch="55." />
            ...
        </shoot>
    </preset>
    <preset name="Another custom preset">
    ....
     </preset>
</papywizard>

Where:

• <preset> name attribute: name used to present the preset in the GUI
• <tooltip>: information for that preset (shown in the information presets template window)
• <shoot>: list of all positions to shoot, described in yaw/pitch attributes of the <pict> tag (one tag per position)

Note: it is possible to define several presets in the same file.

To save time during shoot, take care of the order of positions. For example, don't ask the head to go back to the begining of the new row, it will take too long; instead, reverse the direction and go back for the next row.

You can also import a custom preset file from the File menu. Note that this file won't be automatically loaded at next startup; this is mainly to test your presets before putting them in your user config. dir.

If you add usefull templates, feel free to send them so they could be added as default ones.

Shooting sequence

It is possible to suspend/resume the shooting sequence using the Suspend/Resume button. Once suspended, the shooting sequence can be modified; clicking on any position on the GUI will set the next position to shoot to that new position.

Note: if you are shooting a high-resolution pano, there may be too much preview positions on the GUI to easily select one. In this case, just use the 2 button on both sides of the shooting area to rewind/forward the next shooting position. Arrow keys are also binded to these buttons.

If the Step-by-step box is checked, the shooting sequence will automatically go to suspend mode after each move (before running the camera shutter sequence), and after each camera shutter sequence (before moving to the next position). During the camera shutter sequence, the shutter will be triggered one or more times, depending of the bracketing parameter in the config; no pause will be done inside this sequence.

Cutomization

Style sheet

Since release 1.9.1, Papywizard can load a user style sheet. This file must be name papywizard.css, and must be located in the config directory.

Here is a sample file:

QPushButton {
    color: red;
}

Note: a dedicated page for nice style sheets will soon be created. Feel free to send yours.

Tethered shooting

Tethered shooting is now done through plugins.
