Below is a picture I took of students measuring weight during a Math/Science activity.
I uploaded it to Picasa and used the editing tools there to enhance the picture. I wanted to target the students at this table, but there was a lot of clutter behind them. I cropped out the background students and added some text to explain what they were doing. After adding the text, I changed the color of the text to blue and italicized it. I also used the auto color feature to allow Picasa to give it the right amount of light/darkness contrast.
I will use the edited picture below, as well as many more I will be editing, in my class newsletter.
