The rule you're trying to apply arose in the days before cameras had built-in light meters, and it let you set approximately the right exposure in daylight (this rule works well for moon photography because the moon is illuminated by sunlight). It's called the Sunny 16 Rule, and as the name implies, it means you should set the shutter speed to the inverse of the ISO and the aperture to f/16--not f/8 as you assert.

Here's how the Sunny 16 Rule works. Say you want to shoot the moon the way Lee did. If your camera is set to ISO 400, you want to shoot at 1/400 second and f/16. But don't forget that you can change the shutter and aperture settings and get identical exposures, as long as you keep them "in sync" by increasing one while you decrease the other. In the case of the Hot Pic, Lee shot at 1/200 second and f/8. But f/8 is one stop faster than f/16 and 1/200 is one stop slower than 1/400, so mathematically, the settings that Lee used are equivalent to the traditional Sunny 16 Rule.

Does Paint.NET have the ability to flip a photo?--Cher Staite, Bloomfield, Connecticut

Absolutely, Cher. I'm yet to meet a photo editing program of any kind--online, free, commercial, you name it--that doesn't let you do basic stuff like flip the orientation of a photo. is an excellent free alternative to a commercial photo editor like Photoshop, and you can flip photos both horizontally and vertically from the Image menu.
