Cameras

Canon is widely known as a fine manufacturer of high-end cameras and lenses. Hp is more into consumer electronics such as printers and copiers.

F = 35mm means the focal length of the lens is 35 millimeters. The focal length is the distance from the place where light enters the lens through to where the light rays converge in a point.

For most people, the number (35mm) simply indicates the size of the lens and what type of images you can expect to get with it. For example, in a 35mm SLR camera, the "normal lens" is 50mm. "Normal" simply means when you look through the viewfinder* the lens makes the perspective you see look natural. Nothing appears closer or farther away; nothing appears distorted.

Lenses with a focal length shorter than 50mm (35 mm, 20mm, etc.) are called "wide angle" lenses, because they allow the film (or sensor**) to record a wider angle of view than the normal lens. Lenses with a focal length longer than 50mm are called telephoto lenses (110 mm, 200 mm, etc), because they allow the film/sensor to record more of a close-up view.

This is an oversimplified explanation, but should give you a general idea of what f = 35 indicates.

* Assuming you're not looking through a rangefinder.

** Digital sensors that are less than full frame use a multiplier that varies based on sensor size (e.g., 1.5, 1.6), so a 35 mm focal length will give different results when used on a digital camera. This is just a note -- we'll save the full explanation for another question.

Several different chemical processes have been used in photography. Some of the earliest used silver salts that darkened on exposure to light. These salts were coated on metal plates and then had an image projected on them through a lens. Daguerreotypes used silvered copper plates that were exposed to iodine and bromine vapors to convert the surface silver to silver iodide and/or silver bromide. Once the image was created by exposure to light, the image was made permanent by exposing the plate to mercury vapor which probably formed an amalgam with the sliver in the lighter areas that stuck to the plates. After development, the plates were washed with a hot salt solution which removed the silver from the darker areas where the mercury had interacted less with the silver.

More modern black and white photography uses grains of silver halides suspended in a gel. The chemistry of exposure is typically something like:

Ag+Br- (crystal) + hv (radiation) --> Ag+ + Br + e-

The silver ion can then combine with the electron to produce a silver atom.

Ag+ + e- --> Ag0

Association within the grains produces species such as Ag2+, Ag20, Ag3+, Ag30, Ag4+, and Ag40. The grains containing the free silver in the form of Ag4º are readily reduced by chemicals referred to as "developers" forming relatively large amounts of free silver; the deposit of free silver produces a dark area in that section of the film. The developer under the same conditions does not significantly affect the unexposed grains. Silver halide developers include:

p-Dihydroxybenze, Monomethylparaminophenol,1,2,3 Trihydroxybenzene, p-Aminophenol, Diamonophenol, and 1-Phenyl-3-pyrazolidone.

Once the exposed image has been developed to the desired degree, it is necessary to halt the chemical process quickly to prevent over-development and the production of fog. The solution used to that end is referred to as the "stop" bath. Since developers function a relatively high pH's, the typical stop bath is simply a solution of acetic or some other weak acid. The action of the acid is so rapid it usually requires only seconds for the process to be effectively halted.

The silver halides are only slightly soluble in water; therefore, to remove the material remaining after development it is necessary to convert it to soluble complexes which can he removed by washing. Sodium thiosulfate, commonly termed "hypo," has been used for this purpose since 1839.

The reactions in fixing can be written as follows:

AgBr + S2O3-2 --> AgS2O3- + Br- (adsorption complex)

which is followed by

AgS2O3- + S2O3-2 --> Ag(S203)2-3 (desorbed)

and by

Ag(S203)2-3 <--> AgS2O3- + S2O3 -2; AgS2O3 <--> Ag+ + S2O3-2

Recovery of the dissolved silver complexes is rather important in order to make this process affordable, so the used "hypo" is saved for later processing.

no i dont think so but im trying to find that out myslef but everything ive read so far says that u can't

According to a 1995 interview with Meriam Helbok, Dutch-born wildlife photographer Frans Lanting is self-taught. He has a Master's degree in Environmental Economics from Erasmus University, in Rotterdam, and completed two years of post-graduate work in Environmental Planning at the University of California, Santa Cruz, but he learned photography by reading articles, studying the work of other photographers, and practicing in the parks and hills around his home in Rotterdam.

we all are, for our own sake. we gave away part of our freedom and privacy to government for security. is it a fair deal is another question

"Unlawful Photography????" Never heard of that as a criminal charge. What were you REALLY charged with and then maybe an intelligent answer can be given?

because there actually real pictures that have happened and are more realistic

in 1951

You can't. You can only do it to the iPhone 4g and the Droid.

Benefits:

I would say they are more convenient, the photos are more versatile. You can easily upload them to your computer, which gives you the ability to: 1. Burn them onto a CD or DVD to archive them, vs having a bunch of negatives laying around. 2. E-mail them to friends and family 3. Upload them to internet sites such as kodak.com and shutterfly.com to create things such as calendars, photobooks, mugs, shirts, greeting cards, etc. 4. Easily crop, zoom, and edit photos. 5. You can change color photos to black and whites with the click of a button. 6. You can print them if you want an actual photograph. 7. You only print the photos you want, vs having an entire roll of film developed and printed in order to get the three good photos on the roll. 8. It's cheaper than buying film and paying to get it developed. 9. You can view the photo as soon as it's taken so you know if someone blinked, etc. There is therefore no need to take the same photo ten times to make sure you got a good one. 10. Most of them also take video. 11. You can use any computer and printer.

Harmful Effects:

Shutter lag is the most commonly cited problem with digital cameras, because of the time it takes for auto focusing and the activation of the picture capture mechanism, often in situations where timing is important like sports events, the time between pressing the shutter button and the actual time the camera records the image can mean the difference between getting or losing the shot.

Yes, if it is the appropriate size for your Polaroid camera. You can view compatible products via Related Links, below.

you'll have to see on icarly.com

It is the juxtaposition of several elements in the photograph

I can't remember because I have completed all the missions and I completed mission 9 a long time ago but I think I put it in a bush that was to my left if not that bush to my right if not that then try and click all trees and bushes.

• only phones and exspensivce ones for like 99 quid or somthing

USB cable and desktop computer file manager.

Basically most video cameras are fixed lens so you cannot put a camera lens in it unless it is specially built.

Panavision; Type of lenses- no clue most likely high quality Panavision with very Sharp resolution

it depends what quality it is made from and where it is made and which shops sell it because different shops sell different things at different prices

Well it's a camera that's um digital and uh the format is the whole thing and that is it really good of you to ask it

Anything more specific than that...?

No you do not have to have sign's to show your costumer's you have camera's but it will be better if you did.
