Student Instructions:

Step 1: Click here

Step 2: Change the camera mode on the simulator to Aperture Priority (Av) THIS IS VERY IMPORTANT!!!

Step 3: Set the aperture setting to the lowest number: 2.8.  Press the blue shutter button to “take a picture”.  Your picture will pop up for your to see.  Read the info and then click “X”. This will save it in the gallery below.

Step 4: Now take another photo for each of the following aperture settings:  4, 5.6, 8, 11, 16, and 22.  You should then have a total of 7 photos saved below.

Step 5: View your photos below in the gallery. Click on the first one to notice what aperture setting it was, then click the arrow to view the next. View them all to answer the following questions in your notes:

  • How did the aperture settings affect the images you captured?
  • What do you think are some reasons for wanting to blur out the background in a photo (shallow depth of field)?
  • What do you think are some reasons for wanting to keep the whole scene in focus (wide depth of field)?

Step 6: Clear you photo gallery by deleting each one. Now change the mode back to MANUAL. Set the shutter speed to 1/60 and ISO to 400.

Step 7: Repeat steps 3 & 4 where you take a photo with each aperture setting.

Step 8: Add the following in your notes:

  • Explain what happened to your images this time when you changed the aperture settings.
