Exposure Quiz
If you've read and understood the last four sections of this online book, then you should be able to breeze through these questions. Even if you found some parts of the previous sections confusion, please have a go as it will help you understand the important concept of exposure equivalence. Questions 2 and 3 are real situations you may encounter where it is important for this issue to be second nature.
Question 1. To see how well you understand exposure, stops, EVs etc, try filling in the missing boxes (shaded in yellow). The top line is completely filled in so you get the idea.

Question 2. You take a picture in your cameras full auto mode and it picked the following settings: f/5.6 1/125. Your camera is set to ISO 200. You decide the camera has made the image darker than you would like (underexposed) and you want to increase the exposure by one stop (+1EV). You put the camera into manual mode and decide to set it up yourself. What settings can you use to get the exposure you require?
Question 3. You are out walking in the hills and want to take a picture of your children with the mountains behind them. You put the camera into auto mode and it picks a setting of 1/250, f/4 at ISO 100. The picture is almost perfect - right exposure, kids perfectly in focus. The only thing wrong is the mountains are slightly out of focus. What can you do before taking another picture to get the mountains in focus too?
Question 4. Put these exposures in order starting with the one that will give the darkest image.
