Why no shadows when using camera flash?
When you use a camera mounted flash you do not see shadows in the photo because the light is coming from virtually the same place as the camera lens. There are shadows but they are hidden behind what ever is making them. This can make the photo look a bit flat. Most studio flashes are not mounted on the camera giving the photogropher control over the level of shadow. You see a similar effect if you hold a torch close to your eyes pointing away from them in a dark place. Virtually no shadows. The further you move the torch from your eyes the more shadow you see.

Do SLR camera have zoom?
Yes, SLR's (Single Lens Reflex) cameras have the ability to change lenses from the body to adapt to different photo situations. The benefit is that all functions relating to the photo are functions of the lens. You control the aperture (the amount of light passing through the lens), focus, and zoom from the lens, the only function native to the camera is shutter speed. On automatic SLR's the camera body does all of the light calculations and transmits the information to the lens for you.

Would you use flash on a sunny day?
If you're relating to a camera, there is no real need for it. Unless your camera doesn't take good quality photo, you can turn the flash off and you should be good. Just make sure you aren't under a tree or in a darker area. Don't be right out under the sun, either. My camera fixes the light into the shot too much and it has a faded quality.

Why do people someimes have red eyes is pictures?
The "red " in the eyes of some people is from a camera with a FLASH. In the flash the person is in a dark setting so this makes their iris dilate letting in light from the flash. In the back of the human eye is a blood rich retina that turns focused light that hits it and turns the light into electrical signals that travels through optic nerve to the brain. The brain then turns these electrical signals into a arrangement (digital) that our brain understands as a image. I digress; the "red" eyes in the photo is due to the flash hitting the retina and is reflected back to the lens of the camera

No. The little bit of ultraviolet light in a camera flash is harmless to people. A lot of celebrities smoke, though, and that DOES increase your chance of getting cancer.
The nikon D3 photo shoot results from my camera is not optimum because the printouts and also on the monitor i can see lots of parallel lines at very egular intervals from left to right top to bottom?
Sounds like underexposure. Set the camera on automatic and take a photo in good light. If it looks OK, then that's your problem. You may be pushing the flash too far, or the other camera settings may be off.
How does one produce a photogram?
One can produce a photogram by making a print in a photo lab without using a camera. To do this, one places objects onto a piece of light, sensitive paper in a darkroom. Then, one can use an enlarger to cast light onto the paper to capture the silhouettes of the objects placed.
Is it okay to take a photo of a sea turtle at night?
Only if you do NOT use a flash on your camera. Lights disturb the turtles.
You sometimes appear in photographs with red eyes why?
You use a flash to take a photograph because there isn't enough light to take the picture without one. Because the room is fairly dim, the eyes of the subjects are dilated; the pupils are large, to let in lots of light. The light receptors on the retina of the eye are very well provided with capillaries, the tiny blood vessels that provide blood - and oxygen - to your eyes. (One of the symptoms of hypoxia, or lack of oxygen to the brain, is your sight starting to fade.) When you take a flash photo, especially if the flash is built into the camera, the light from the flash goes into the eye, and hits the retina. Because the retina is mostly red blood vessels, the red light is reflected while the other colors are absorbed. So the red light bounces off the retina of your subjects' eyes, and back to your camera. Presto! Red eyes! You can reduce the "red eye" effect by having the flash several inches away from the camera lens. The red will still be reflected, but it won't be reflected straight back at the camera; the reflection will bounce out to someplace away from the camera, and it won't be as noticeable.
