Correct! You have chosen the rendering!

Here are the images again, labeled:

The photo.	The rendering.

You can tell the rendering from the photograph in 3 main ways:

• The cracks in the corners of the box are too straight.
• The acrylic ball's refraction is too straight. (Partly due to the ball being approximated by a perfectly refracting, perfect sphere. Partly due to modelling the PVC pipe as a cylinder with sharp edges, instead of rounded edges).
• The mirror's reflection is too blurry and faint. (The index of refraction is also a bit wrong, but you would not know which was the correct one).
• I resized the photo in XV, causing jaggies on various features.

Below are the full 512 x 512 images, uncropped.
