This workshop introduces students to Pixlr, a free online editing tool similar to Adobe Photoshop. The class teach students how to do basic editing of their photographs and familiarize them with this useful software.


Class Outline:

This class is meant to introduce basic photo editing using the free online Pixlr Editor ( I have found the best way to teach this subject is to start with 4 or 5 pictures that need editing. You can either find them online (already in need of work) or find good pictures and mess with them until they are in need of editing. The latter works well because when it comes to class time you know exactly what you need to work on and how much to do to get your back into good form.

The handout provided goes over a lot of tools in pixlr which we do not go over in the class but for which it is useful for your students to know about.


  • Open Pixl

    • Explain how to open fileà from file on computer, web url, ect. (also that you can create blank documents although we will not be doing that)


  • Open an image you are going to use to practice changing image size and cropping

    • Before beginning the activity, go over the basic layout

      • Toolbar on the left (which the handout goes over

      • Navigator, layers, and history boxes

      • Navigation bar at the top: File, Edit, Image, Layers, ect.

        • Next show how to change image size

        • Explain the difference between changing image size and cropping. Demonstrate and have them practice. This is a good opportunity to show them how to use the history box to go back after they make changes.

        • At this time you can also explain how to save the file and if they would like to know explain about different formats that you can save in, i.e. the difference between JPEG, PNG, and TIFF (also what RAW photos are although Pixlr does not save in RAW)


  • Open second image and work on adjusting Brightness and contrast and also vibrance and saturation

    • Be sure to ask if they would like you to explain concepts and what all of these things do and why you would do them


  • Open third image and work on adjusting levels using the Histogram

    • This is a bit redundant. A different way of achieving some of the affects you did in the previous picture but it is helpful to show the histogram and explain about tones. You can also talk about saturation and hue at this time.


  • Open forth image and practice using the Lasso to copy an object and then duplicate it. I used a picture of a dog with a ball and duplicated the ball so the dog had 4 instead of the 1 he started with.


  • Open fifth image and use the tool to correct red eye

  • Ask for questions and advice about available resources

    • There are many online guides for pixlr that students can look at if they wish to learn more—both written and video recorded. There is one particularly good video on youtube (Pixlr Tutorial & Training - 1 Hour 21 Minutes - 32 Chapters) that is very comprehensive.
