Image+Editing+Lesson

=__Image Editing Lesson__= There are many different image editing programs on the market and most of them will work for the first step in preparing an image for use on the OmniGlobe. One of the best programs would be any of the Adobe Photoshop products. These programs run between $69 and $199. There I several program that may already be on your computer or available as a free download that will also serve the purpose. A few programs that do not work for various reasons are: iPhoto, Versions of Apple Preview older than Snow Leopard operating system, Picasa, Versions of Microsoft Paint older than system 7, this includes Windows XP. When you are trying to change the scale of an image be sure the program is not just cropping the image, you will loose part of the image this way instead a resizing it.

__Size Requirements:__
Always use pixels when adjusting the size of an image. A pixel is an individual dot that together with other pixels make up every image. An image with more pixels will typically display better on the OmniGlobe. If you do not have enough pixels, you image will become unclear and also have black "finger print" spots when displayed on the OmniGlobe.

A**RC recommended number of pixels:** 2400 x 1200 pixels **!**
The end goal for any image that you convert is to get it to have a 2:1 aspect ratio. What that means is that the image is twice as long as it is high. This ratio must be exact! If you are off even by 1 pixel you will not be able to convert the image in Geometer. It is recommended that you round to the highest whole number for ease. For example: if you find an image that is 2140 pixels by 976 pixels, you should convert it to 2200 x 1100 pixels. This will still be big enough. It is not recommended that you try to take a small image such as 600 x 300 pixels and stretch it to be a larger size such as 2400 x 1200 pixels. This will only result in a poor quality image, you might be able to make the image 1000 x 500 pixels but it will be image dependent.


 * Minimum number of pixels: 1000 x 500 (Warning this still may result in "fingerprinting")**
 * Maximun number of pixels: 4000 x 2000 (If the image is larger than this it takes too much time to load)**

When you are saving your images be sure to save them as either: ".jpg, .jpeg, or .png".

=__ Image Conversion Assessment: __=
 * 1) Practice converting the image below using any available software of your choice. Convert the image below so that it the aspect ratio is 2400 pixels x 1200 pixels and saved as .jpeg or .jpg. Post the converted image to the Omniglobe wiki page that has been created for you when you are done. [[image:IMG_0267.JPG width="217" height="164" caption="Right click to save image"]]
 * 2) Through the remainder of the course, you are expected to find, convert and post to your OmniGlobe wiki page, at least 15 more images for the OmniGlobe. The images can be for use with your lesson plan or stand alone images. Please be conscious of copyright. **It is very important that you post the original image and your converted images!** All images should be converted to a logical and appropriate pixel ratio and saved as a .jpg, .jpeg, or .png.
