That is: if you show this photo to people that you know and you compare and contrast _how detailedly_ you can imagine the apples, that can help.
For example: are you imagining a _specific_ apple? What high-level color is it? How about more specifically? How does the color change across the surface? If so, does it have any distinguishing features? Leaves on the stem or no? What does the bottom look like? Can you turn it around and describe that?
Folks who are high up on the spectrum (like 1) can often answer these questions specifically, whereas as you go down the spectrum these tasks seem progressively more impossible.
