The length of time required to photograph star trails varies depending on how long you would like the trails to appear. Generally, with a 10 minute exposure, you will have very faint trails. With a one hour exposure, you will have trails roughly four times as long. With a 180 minute exposure, you will have trails that are substantially longer, and will noticeably fill the picture. The longer the exposure, the more white the picture will become as it is filled with star trails.

What can be seen from the photograph?
If there is a specific photograph you mean it is not available to us that could answer.If you wonder what in general can be seen in aphotograph the answer would be: What the photosensitive medium captures during the exposure.
Do you need permission to photograph a public statue and use it in a book?
A photograph of a statue would be considered a derivative work; if the statue is protected by copyright, you would need permission from the rightsholder to create the derivative work.
How would a three hour time exposure photograph of stars in the northern sky appear if earth did not rotate?
The stars would be brighter points of light. Without the Earth's rotation, the Earth would not be moving enough to create the lines of light that ordinarily appear in an uncorrected stationary time exposure. Depending on the clarity of the sky, the entire image could be grayed by scattered light (light pollution).

How would a three hour time exposure photo of stars in the northern sky appear if the earth did not rotate?
The photograph would record far more stars, nebulae, and galaxies than the naked eye could see. There are many thousands of such photographs to be seen on the web. Any camera capable of long exposures with an equatorial mount and a clock drive could create such a photograph. A clock drive, which turns the right ascension axis of the mount at the speed of a hour hand (hence the name), counteracts the rotation of the Earth.
What year was the first photograph of a live person taken?
Generally accepted to be 1838 or 1839, by Louis Daguerre. The unknown person stopped to have his shoes shined during the 10 minute exposure. If not for this, his presence, like everyone else in the street, would not have been captured due to the long exposure.

How would a three-hour time exposure photograph of stars in the northern sky appear if earth is not rotating?
This answer depends on the location of the camera taking the picture. If the camera is on the ground, then the exposure would come out clearer if the camera was not mounted on a system that could automatically move the lens. If the camera was in LEO (Low Earth Orbit) it wouldn't matter if the earth was rotating.
Can you paint on a photograph and what type of paint should you use?
You can paint on a photograph. Normal acrylic would work.
Is buying a photograph envelope a waste of money?
It really depends on the purpose and the occasion. For a regular photo, there would be no need to buy a photograph envelope, but if it is a delicate photo and/or you want to send it to someone, it would be worth it to but a photograph envelop.
