Q about 'macro' camera settings

[sheepherder]

This is a vertical shot; high noon, bright sunlit day, in shadow, using the beige towel. The towel looks white outside. I aimed about an inch over the top of the slide. 'Close Up' setting. I can still see reflections in the flat surfaces. Colors are still out of whack; my grips are brown.

But at least the slide doesn't look quite as warped/bent.

Second pic is scanned on my HP OfficeJet 7210 All-In-One, resized, and Gamma corrected (but not as much), again with the beige towel.
