Question 39

1. Your boss needs a new image for that "social media face-tooting interweb thing" he keeps trying to use. Bob from marketing gave you a photoshop file (called "rafting.psd") of the boss from the last team-building retreat. You decide to use that, so on the desktop of your computer you quickly click on the file name, select and delete the ".psd" part, and rename the file "rafting.jpg" since you know that that web browsers will recognize JPEG files. What is true about this file?

   You cannot use it where you would usually use a JPEG because you didn't make a JPEG.

   You made a proper JPEG file, but with too much compression since you didn't choose the compression levels.

   The image is a proper JPEG, but with the wrong colors.

   The image is a proper JPEG, but it's all glitched, which is totally cool.

   You made a proper JPEG file, but it's uncompressed, so it's too big.

Question 40

1. You are trying to make an animated film. What things do you need to have for the individual frames to appear as motion (that is to say, to achieve persistence of vision)?

   Sufficiently high bit depth.

   Sufficiently high frame rate.

   Frame rate that is not too high.

   Sufficiently high resolution.

   Intermittent interruption every frame.

   The proper codec.

   Small changes from frame to frame.
