''The Cheese application allows you to capture pictures of videos from a webcam...''

== Using Cheese WebCam Application ==
[[Image:cheeseButtons.png|thumb|200px|The three modes of Cheese (left-to-right): '''Single Photo''', '''Video''', and '''Multiple Photos''' ]]

==== How to Launch Cheese WebCam Application / Modes of Operation ====

'''To launch the Cheese application: Select the Menu in the Panel''' Click '''APPLICATIONS''' -> '''SOUND & VIDEO''' -> '''Cheese'''. If you are using the Docking station (Westminster Computer Lab), in the docking station panel, click the menu icon, then select the menu item called '''SOUND & VIDEO''' -> '''Cheese'''


On the left-hand-side of the Cheese application window, there are three separate modes:

:*'''Single Photo'''
:*'''Video'''
:*'''Multiple Photos'''


==== Taking a Simple Photograph ====


<table>
<tr>
<td>
By default, the mode in Cheese is set to "Single Photo.


To take a picture, click the '''"Take a Photo"'''. The camera will countdown (3-2-1), then a simulated flash will quickly display to indicate that a photo was taken. The picture should appear in the bottom window. You can double-click this photo to view it in an image viewer application, or the user can drag this picture to a directory for further processing.


==== Using Special Effects ====

The user can select special optical effects prior to taking a photo.

In order to select an effect, click on the "effects" button. Then select the special effect, then click on the "effects" button to return to camera mode. The user should see the type of effect displayed, and can now take the photo. If the user wants to turn off special effects, then click on the "effects" button, click on "no effects", and finally click on the "effects" button again to return to camera mode...

</table>

==== Using Cheese to Create a Stop Motion Video ====

This application correctly numbers each picture for loading all pictures in correct sequence into a non-linear video editor, and no uploading is required. Unfortunately, there is no macro capability with this webcam, so you will notice a blurred vision in some of the frames... Recent versions of Ubuntu are better at detected various manufacturers of webcams.

Make certain your webcam is connected to your Ubuntu system, and '''make certain that you have the cheese application installed on your system (is does NOT install by default)'''. To learn how to use the Synaptic Package manager to install applications, click on the following link:<br />[  [[Install Applications in Ubuntu]]  ]. Note: For Westminster United church users, the Cheese application has already been installed...


The Cheese application is designed to capture pictures, video and audio. There are buttons on the application to allow you to select the type of capture you would like to do. The default setting is to capture pictures from the webcam. '''It is recommended to turn-off the "countdown" and "flash" effects for each picture taken before proceeding with your session''' (can be annoying if you are capturing a long series of photos for stop-motion photography) by selecting the '''Cheese''' menu, and '''de-select the "countdown" and "flash" checkbox option'''...


To create a stop-motion picture capture session, '''move the Lego piece by very small amounts for each sequence''', then '''click on the "Take a Photo" button'''.
You should see the picture appear in the viewing area below. If you are not happy with the picture you can '''remove it by right-clicking on the picture and selecting Move to Trash...'''


All pictures taken in the current Cheese session are stored in the '''Pictures/Webcam''' subdirectory of your home directory.


'''It is recommended to move those pictures to another storage directory from your Video Editing project'''. For example, create a folder by project name, and then create a subdirectory called pics, and move those pictures to that location. '''Note that when you move those pictures, then the Cheese application no longer stores those pictures, and will be ready for the next picture capture session'''...
