Use image editing tools to modify your image.



  1. Open a picture that you have taken.
  2. View the Levels (histogram) of your picture under the Color menu item
  3. Move the mid-tone level to the left. What happens to your picture?
  4. Use the Lasso tool and select an area of your picture

  7. Use the Rectangle select tool and draw a box around your image.
  8. Choose Crop to Selection under the Image menu item.

  10. Use the Oilify filter located under the Filter menu item in the Artistic group. Experiment with other filters too.
  11. Add any cool effects to your picture and post it to our class social site with the tag “sp14dm3a”.

  1. I have trouble hearing the weekly lesson videos, even with the volume turned up completely on the computer and the video. Is there any way to increase the volume via blackboard so the playback is louder?

    • Some of the videos do not have audio. Look at the title and see if this is the case. They were meant to be a quick video to highlight something from the assignment instructions.

  2. We’re supposed to put some of these assignment items under assignments, but I am unable to open anywhere to post there. i’ve done everything for the assignment, but don’t know where to post it.

  3. Mr. Jarrell,
    Can you tell me how to submit another attahcment for the assignment please? I attached one document and not the other because I thought I would be able to submit more than one, but I can not get it to let me.

  4. Either one is fine.

  5. Do we use the original picture or the one modified and posted?

  6. HOw do you change the opacity to 50%? I have looked everywhere for it and can not find it! Please help me!
    Your online student,
