Find my pictures sharp enough.

So was my reaction.
Maybe it's not a mistake, but very confusing and a bad way to explain things.

Don't quite understand the 640 ISO, ND filter and pol filter combination.

No self-timer.

It seems to me that the baby photo are no real pixels. More a blurred picture with a grid overlay.
Within the individual 'pixels' are different shades of gray and that's not the case with a pixel...

Placed 98^th in the challenge.

Placed 41^st in the challenge.

We should abandon the obsolete video-tubes sizes of the 80's. We're talking here about photographic sizes, like 35mm, 24*36mm, a 105mm focal lens and so on.
Ask a person what is bigger: 1/2.7" vs...

= 5.58 * 7.44 mm (41.5 mm2)

Still not satisfied:
2 * 21.5 mm ?
4 * 10.75 mm ?
4.5 * 9.5556 mm ?
6 * 7,16665 mm ?
43 is a prime

Metric size sensor area please.
