Cameras

You are actually seeing images of the retina, the layer of cells at the back of the eye. There are many blood vessels in that part of the eye, as well as a very high concentration of light receptor cells.

You will note that in virtually every photo in which you see 'red eye', the photographer used a flash. The flash was probably on the camera, making it possible for light from the flash to make a reasonably direct trip from flash to retina and back to the camera. The need for the flash suggests that the ambient light level is low enough for the subjects' irises to be open. The flash and exposure happen so quickly that the iris doesn't have time to adjust by closing a little. The result is the slightly creepy effect that we call red eye.

This is why most cameras today have a pre-flash option for photos of people and/or animals. A few short bursts of light cause a person's irises to close a little, and red eye is almost always avoided. If this option is not available with your camera, then placing the flash at an angle, away from the camera, may also help reduce red eye. The problem can also be fixed easily with most photo editing software packages.

now Danielle is writing this :) digital cameras might seem better but are they?? They might be easier to use but they are actually harder because you have to focus them while the digital one is easier because they are easier to print and taking. This is why they are better than digital cameras.

I think the above answer confuses film camera with digital camera! The opinion expressed above seems to favour film camera rather than a digital one. Possibly so, but before submission the author of that statement above should have revised what he wrote!

If it didn't get wet for very long just simply dry it with an everyday sort of thing (cloth, tea towel etc.) and it should be OK if you leave it for a bit. If you find something does go wrong and the contents of it are important, you can simply remove the cover, no screwdrivers needed but in an ordinary way, take the memory card out and insert it into a new camera.

This info is for a camcorder that WAS NOT ON. If it was on, it has no suggestion of being saved and it would be too dangerous to take the memory card out so you shall have to accept it has gone.

The best painting in the world is the one of my grand daughter, of course. Besides that, there is quite a difference of opinion. Some would go for The Mona Lisa. Some would chose The Last Supper. And Some would choose the Ceiling of the Cystine Chapel. All of these pictures are well done and all of these pictures go beyond the picture. The Mona Lisa has a semi-inviting smile. What does it mean? In the last supper, Jesus has just said a lot of information that is difficult to understand. Judas, with his head turned away knows it means that he will betray him. The other 11 wonder what it will mean for them. The painting of the ceiling of the Cystine Chapel shows the Biblical Story of the Creation of Man. It makes you think what possibilities did man have before he chose the one he picked. A movie that affected a number of people the same way was Dr. Zhivago. (A lot of others did not like it.) A great painting is one that looks beautiful in and of itself and also has you consider possibilities on beyond the painting. What were Adam's possibilities? What were the disciples thinking. What does Mona Lisa's smile mean?

This varies widely depending on the camera. If you're talking a throw-away camera with a single element lens, an inch or so. If you're talking a large format portrait camera (film plate 4 x 5) the lens can be a foot away or more.

Exactly ! SLRs have the lens moved forward to allow the reflex mirror free passage (25-30mm for 35mm film) whereas my rangefinder has less than 3mm clearance between the wideangle lens' rear element and the focal plane shutter.

Police photography basically deals with forensic photography. In most cases, it deals with a scene of a crime while the term 'photography' generally mean anything that deals with pictures. Hope that helps...

Annie Leibovitz has used many camera during her long career, including the Hasselblad 6x6 medium format and the Mamiya RZ-67.

Although both cameras use the same size 120/220 roll film, the Hasselblad produces square 6x6cm images on film, while the Mamiya RZ-67 produces 6x7cm rectangular images.

Photoshop can edit in amazing ways. Also some computers (like mine) have a webcam that i can take pictures on or videos.

To take pictures, like any other camera. The Brownie Box camera by Kodak was one of the first mass produced ones and was named because it looked like a box. The earliest ones had to be sent to Kodak to have their film removed and replaced. They had no flash, no focus or aperature settings and worked outdoors.

I didn't know movie cameras used to make sounds..

Also referred to as an extreme short focal length (around 15mm) the fish eye lens will gather a whole lot of image and provide unlimited depth of field. However, the distortion is so great that horizontal and vertical lines that are off the central axis are extremely bent to the point where they curve around the perimeter of the lens. Often, the image itself is a circular one.

They should work on Minolta digital cameras, and possibly the new Sonys as well. Check carefully into the camera specs.

. Professionals mainly use the SLR type of digital camera and sometimes use "digital backs". As for makes, my personal opinion is to go with either Canon or Nikon cameras. .

Yes you can !... The apps and hardware on the handset are not restricted by having no service. No service simply means you cannot send or receive calls, texts or data.

I'm presuming you mean photographic camera and not the camera obscura.

It is not really a question that can be definitively answered as written. The earliest uncovered evidence of lens making dates back several centuries (from Persia, I believe), while the principle of the camera obscura (co hereinafter) dates back to about 300 B.C. The first device constructed to employ the principles was built around 1021 A.D, yet it was not even given this name until 1604. I think the earliest known reference to adding a lens to the co was written around 1568 (Daniele Barbaro), and Johann Zahn constructed a co small enough to be easily portable about 1679 to 1685, depending on what reference you cite. I do not know if he designed the lens that made this possible or simply incorporated one into his design. Therefore, this forerunner of the portable photographic camera was in existence about 150 years before the "invention" of photography. From this it is evident that the co with its lens predates the concept of photography by a long shot.

Therefore, the device used in 1826 to make the first permanent photographic image employed chemical and optical knowledge that predated it by many centuries. Perhaps it is more a question of how the lens and the camera obscura were adapted to suit the purpose of making photographs. Photography itself is a progession and adaptation of technology rather than some sort of eureka moment.

To put this in another context, we probably would not have the automobile if someone had not thought to hitch a horse to a wheeled contraption. Maybe this was the Romans, but that's another topic and I think you will get the point.

You are not clear on whether you mean negatives, slides or prints; manually or by machine; color or black and white. The answer could be a long, long one if it is to be meaningful as there are many steps, controls and apparatus involved. Please Google it or borrow books from the library to appreciate the depth of the subject.

camera used for cricket are DSLR Cameras where it must have more FPS that is frames per second like 30fps or 60fps and lens used are zoom lens or wide lens

For info on toning, see "What is toner for in photography?"

Dying involves applying either oil based or water based dye with a very fine brush (for small areas) or cotton applicators for large areas of a print. The practice was usually reserved for adding a single element of color in a black and white print.

The top 5 best camcorders according to experts include the Canon VIXIA HF M52, the JVC HD Everio GZ-VX815, the Sony Handycam HDR-PJ430V, the Drift HD Ghost and the Sony Bloggie Touch. It is not possible to pinpoint one specific camcorder as each is slightly different and it depends on what you are trying to achieve, as to which one would be best for you.
