what is a photo?

Question

I understand what a photo is, but has any one got an explaination how we catch a moment off time on a piece of photo paper.

Answer 1

It doesn't seem as if anyone has answered so here goes.

Glass or Film with emulsion containing silver halides is fixed to the media.
Exposed to light they are darkened.
When developed the unexposed portions are washed away and the remaining image is fixed with a second chemical.
Now washed and left to dry you have a reversed image to that photographed.
Projected onto light sensitive paper the transparent parts make the paper go dark and the reverse applies to the darker parts.
You now have a B&W photograph.
Colour has different chemicals more of them and more complex processing and requires very strick control methods.

Answer 2

Here is a brief synopsis:

When you point the camera at something you want to take a picture of and push the button, the shutter inside the camera opens for a split second and catches the image on film or a "negative". The negative is then used in combination with chemicals in a dark room to bring the picture to life on paper.

Hope that helps...

Answer 3

What fun to be photoed together,
What luck for a break so opportune.
Oh, what a lark
To be posed in the park
Underneath the adolescent crescent of the moon.

A chemical reaction of light onto a sensitive film

Or, an image captured by a digital camera

Answer 4

Im pretty sure that its something like this.....

ever seen how light shone through a prism exits the prism broken and shows all its colours? Well i guess that due to a mixture of photographic paper and the chemicals upon it, when the lense of a camera opens and lets the light in for just a split second, the chemicals react to the light and leave the representation on the paper.

Pretty cool stuff when you think about it

Answer 5

If film then it's a chemical reaction caused by light on the photo film.
If digital, then it's the light caught by a chip which is covered in a matrix of light sensative bits and then converted to an image using them there computer do dars.

Answer 6

A photo is an image (or a representation of that on e.g. paper) created by collecting and focusing reflected electromagnetic radiation. The most common photographs are those created of reflected visible wavelengths, producing permanent records of what the human eye can see. Or yes it could be magic.

Answer 7

Its something to do with exposing a special kind of paper to light for a certain amount of time. Normally its a nano second, but if you expose it for longer you can get the pictures where it looks like everything is blurry and moving very fast.

Answer 8

PHOTO was the name of an American photographic magazine geared towards men. It was published monthly by the Official Magazine Corporation beginning in January of 1951. The magazine mainly featured photographs of scantily-clad women, although there were also exposés, featured articles, and examples of photojournalism.

The miracles of science....did you know that in Victorian times they had to sit still and pose for 5 minutes to get a picture? Something to do with light and aperture. Just thought I'd share that with you....

Answer 10

Wow, what a great question! I have no idea how they capture an image. I watched some special about early photography, but I didn't understand the process.
