Nice summary of what the different exposure controls do to an image. Depending on the situation, we may want to tradeoff between the different controls to obtain the best quality image we can.

Interesting how there's no real equivalents for this in human vision outside of maybe our eyes dilating for aperature - but for the most part we can't really control the "frame rate" or "gain" of our eyes

This is a very clear disagram correlating all the metrics to show what the outputs do. I think it's pretty cool that sports photographers probably know what exact setting to switch to capture the moment. There's so many different combinations of things to try.

Is this related to the sample rate that we learned in the very first part of this course? It reminds me of when the sample rate is lower than the actual frequency the image turns out to be aliased. Is this a similar effect that as the shutter speed gets higher it fails to capture the exact motion.

I think that this diagram explains the exposure controls really well. It's also easy to see how motion blur is caused on the third row but it can be affected by other variables as well.

So as the aperture decreases, we allow more light into the image and the depth of field decreases. The shutter speed determines how long a sensor is exposed to light, so a slower shutter speed will cause motion blur. A higher ISO will introduce more noise into the image.

Here's some useful videos for visualizing how both aperture/shutter speed work: https://www.youtube.com/watch?v=7R9ZTxoTOSk https://www.youtube.com/watch?v=YojL7UQTVhc
