Usage of "screenshot" vs. "digital photo"
Solution 1:
No, I am in college and we do use the words screenshot and digital picture in accordance with what you have said: "screenshot (capturing the digital rendering of an image by the same device that renders it) vs. a digital photo (capturing a live image in digital form)". For example, we use the word screenshot only when we capture the image already in the screen of a smartphone by an internal option available in the device itself. Anything else captured via the camera is referred to as an image or a digital picture.
