===Creating an image resource===
 +
Images can be used standalone, or in a sequence as an animation, or in combination with text to create picture stories for communication and teaching. A picture can speak as much as a thousand words! With increasing use of ICT, creating  and editing image resources is becoming more common.  You should be familiar with the free and open source tools available for creation and editing of image resources.
 +
 +
A simple and easy way to create an image OER is to take a photo of the object you want an image of, using your camera or a mobile phone. Of course this will apply only where the topic is such that you have objects you can take a photo of. Sometimes an image can also be a digitization of hand-drawn images or paintings. Digitized representations of student drawings or paintings can be a useful collection of image resource.
 +
 +
==== Digital drawing ====
 +
You can also use a drawing software application such as Tux Paint to draw an image. 
 +
 +
Open Tux Paint on your computer, through Applications → Education → Tux Paint
 +
 +
The screen contains two tool bars on either side of the drawing canvas. The left side tool bar contains drawing and editing controls. The right side tool bar provides the various options for the specific tool that you select on the left side tool bar (image 4). For e.g., when the "Paint brush" tool is selected on the left tool bar, it shows the various brushes available on the right tool bar. When the "Rubber Stamp" tool is selected on the left tool bar, it shows the different stamps you can use, on the right tool bar. At the bottom, you can see a palette of colours. Below this, at the bottom of the screen, Tux, the Linux Penguin, provides tips and other information while you draw.
 +
 +
You can use the ‘brush’ tool, select the brush and the colour you want and paint on the drawing canvas. You can use the stamps for drawing / inserting predefined shapes into the canvas.  The left tool bar also has an eraser in case you want to erase any part of your drawing. You should familiarize yourself with the tool options by simply using them, in your drawing work.
 +
 +
The files created by you, are stored in the home/.tuxpaint/saved folder, in the 'png' format. To open the .tuxpaint folder, you may need to select the 'view hidden' files in the /home folder on Ubuntu. The file name will begin with 'year+month+date' in YYYYDDMM format, followed by a serial number.
 +
 +
==== Creating image resources using a screen capture tool  [https://help.ubuntu.com/stable/ubuntu-help/screen-shot-record.html Screenshot] ====
 +
One of the simplest and yet very powerful ways of creating an image is to simply take a picture of your computer screen. You may have opened a web page on which there is an image or some text you want to store as an image, or it may be from a file on your computer, or it may be a snapshot of a video you are playing.
 +
 +
You can use the tool Screenshot for this. Open Screenshot on your computer, through Applications → Accessories →  [https://help.ubuntu.com/stable/ubuntu-help/screen-shot-record.html Screenshot]
 +
 +
You have an option of capturing the entire display on your screen or selecting a smaller area. For the latter option, chose ‘select area to grab’ (image 5). Then use your mouse to drag drop the (rectangular) area you want to capture. (Move your cursor to the left top of the area, keep your left mouse click pressed, move the cursor to the right bottom point and release it).
 +
 +
==== Creating and editing image resources using an image editor  [https://www.gimp.org/ GIMP] ====
 +
GNU Image Manipulation Program (GIMP) is an image editing software. GIMP can be opened from Applications--->Graphics---> [https://www.gimp.org/ GIMP Image Editor] (image 7). GIMP is very powerful with many sophisticated features. We will learn a few commonly used functions in image editing:
 +
# Cropping an image
 +
# Adding text to an image
 +
# Reducing the size of an image
 +
Once you have opened the GIMP application, open the image you would like to edit (image 8). You can see the menu bar providing different options for editing the image.
 +
 +
===== Cropping an image =====
 +
Often, you want some part of a larger image to re-use in a different resource.  GIMP allows you to select parts of an image - in different shapes or even using a freehand selection to select parts of an image.
 +
 +
This is different from a screen shot where you can only grab an area that is in the shape of a rectangle. You can select parts of an image from Select Tools → Selection Tools → Free Select You can move your cursor on the image to outline the area you want to crop, this is free hand, not necessarily in the form of a rectangle. Then crop the image to your selection through Image → Crop to Selection (image 9). We have cropped the image to free select only the teacher and the student (see the dotted line in image 9).
 +
 +
You can export this cropped image using File → Export as and export to an image format like .png or .jpeg.
 +
 +
==== Adding text to an image ====
 +
You may want to add a caption to an image and make that caption a part of the image itself.
 +
Select Tools → Text.  A text tool box appears.
 +
 +
Place your cursor where you want to type your text. You can format the text (change font size, colour) through the Text tool box.
 +
 +
In our image, we have added the text ‘Digital Storytelling, Health centre’ and selected the yellow colour for the text, since it will display better against a dark background (image 10). (Tip - the text should be in a colour contrasting with the background, for easier visibility).
 +
 +
==== Reducing the size of an image ====
 +
Sometimes image files can be heavy (compared to text only files). You can reduce the size of an image using GIMP.  Select Image → Scale image (image 11). You can reduce the resolution in the form that opens. The more you reduce the resolution, the greater the reduction of file size. You should then over write the file, File → Overwrite <your file name>. GIMP will open a form asking for reduction in quality. You can reduce quality up to 30% without visible degradation in quality.

|'''Student activity time''' - 
 +
You should use GIMP to work on your image OER that you have created. You should use the text input option to enter captions on your image OER. You can crop a part of an image which contains the message you want to convey. You should also try and reduce the size of your images

=== Creating an audio-visual resource ===
 +
 +
==== Creating audio resources using your audio recorder on your mobile phone ====
 +
You can record an audio clip using your mobile phone itself, using any audio recording app, such as ‘[https://play.google.com/store/apps/details?id=com.sonymobile.androidapp.audiorecorder Audio Recorder]’. You can copy the audio file from your phone to your computer for editing to create a resource. While recording, make sure that no copyright music or sound is playing in the background.
 +
 +
==== Creating video resources using your video recorder ====
 +
You can record a video clip using your mobile phone itself, using the camera on the phone. While recording the video, take care to ensure that you are not shooting copyright materials or private spaces. You can copy the video file from your phone to your computer for editing and re-mixing to create OER.
 +
 +
==== 5.2 Creating a video resource using a screen-casting tool - [http://recordmydesktop.sourceforge.net/about.php RecordMyDesktop] ====
 +
Screen casting is also a simple yet powerful way of creating a video resource. The [http://recordmydesktop.sourceforge.net/about.php RecordMyDesktop] software records the computer output display as the video and audio (image 18). This can be used to record the functioning of a software or any educational application. In addition to the audio played on the computer as part of the running of the application, additional audio spoken and provided as an input to the computer can also be recorded as a part of the video.
 +
 +
You can set your computer audio output to mute, and provide the audio entirely from an external source (which can be your own voice, or an audio recorded earlier on your mobile phone or computer). In this way you can combine the video from the computer with your own narrative to make a lesson plan on a topic.
 +
 +
There are some powerful ways of using this tool for creating video OER:
 +
# You could "slide show" your presentations or play your images and add a narration to it to explain further.  This can be shared as supplementary materials for your class and can be used by students who need reinforcement, additional reviews of your lessons.
 +
# You may have used a particular software or educational application to demonstrate a concept in class. You could use the screen cast application to re-create the lesson by recording your description of the activity and sharing with students.
 +
# Dubbing a video can create a resource in another language.  In a teaching setting, you may want to use an existing video, and voice over it to add explanations to reflect the language and learning context of your class; this can be done quite effectively using this  application. To dub a video using [http://recordmydesktop.sourceforge.net/about.php record my desktop] , you need to set the sound settings on your computer to ‘mute’ (no output). Then start [http://recordmydesktop.sourceforge.net/about.php record my desktop] application and play the video. As the video plays, read out your script. The audio read out by you will be combined with the video being shown on the screen to create the video in your language.
 +
Make sure you are not displaying copyright material on the screen when recording the video. If you record any copyright material in the video, it will be a copyright violation.  Select Applications →  Sound & Video →  RecordMyDesktop (image 17) to open Record My Desktop.
 +
 +
'''Configuring record my desktop application'''
 +
 +
There are different settings that you can choose for recording on screen cast software based on the kind of content you are capturing on the content as well as method of sharing and publishing.  Here are some pointers for changing the settings.
 +
 +
Take any OER video you like, which is in accented English spoken in the USA or UK and dub it with your own voice, in English or your native language. Save the video files in your personal digital library, you could save in a sub folder called 'Video documents'. The effectiveness of this editing will depend on how well you have prepared the script to match the original video. Also to make the recording more effective, you should use a microphone connected to the computer. You should record a couple of times and listen to it, to get feedback on what to do to improve, such as raising the audio volume, providing gaps and voice modulations etc. After you practice a few times, you are bound to get a good video!
