Good vs Bad Photos
The photo is blurry, taken at an angle, and a shadow covers the bottom of the page. Background objects are also in the shot.
Retake these
The photo is out of focus and the page is curved, so the numbers in the grid can’t be read. Part of the page is cut off.
The question, table, working and graph are all visible and in focus. Numbers and axis labels can be read easily.
Good Photos
Taken straight on in even light. Every word is sharp and readable, and the page fills the frame.
