A little perspective

Detective

Each day, four objects share one scale. The marked reference is correct. Find the one incorrectly sized object among the other three in up to three guesses. Wrong guesses are ruled out. Finding it on guess 1, 2 or 3 earns 40, 25 or 10 points. Then resize it once for up to 60 more. A new scene opens at 00:00 UTC.
