Answer: Pinhole camera
A pinhole camera has no lens but a small hole on one side of a box that is otherwise completely light proof. When pointed towards an image of some sort, the light from this image is reflected upside down on the opposite side of the box to the pinhole. Now here we are in the 21st century and I still can't figure out how that works. This miraculous (to me) discovery was noted by the Chinese philosopher Mo Di, and by the Greek mathematical experts, Euclid and Aristotle, in 500 and 400 BC.

Answer: Louis Daguerre
Though the first successful picture was developed in 1827 by Niépce, it took 8 hours to expose. Two years later Niépce joined Daguerre in a partnership, but he died only four years later. Daguerre is believed to be the "father" of photography, since by accident he exposed a plate in his chemical cupboard.

Answer: discovering that silver salts darkened when exposed to light
In 1724 Johann Schulze conducted an experiment with silver and chalk that proved this mixture produced a better photographic effect than simple untarnished silver. Still, the end result was not completely desirable, because the silver salts used continued to darken more and more as they were exposed to light.
Nevertheless, his experiment did provide the basis for further studies into the development of camera images.

Answer: It projected images onto a wall
The camera obscura allowed the light into the dark box in the same fashion as the pinhole camera, but this time, the image seen therein could be reflected back up onto a wall for an audience to see. The inclusion of mirrors within the box allowed the upside down image to be projected on the wall the right way up. This method of photography was used by Anthemius of Tralles (474-558) in his work. The smaller the pinhole, the sharper the image became. So simple, yet so astonishing.

Answer: a telephoto lens
Telephoto lenses allow the user to take pictures of things farther away. They are commonly used when taking pictures of wildlife or sports. They are usually longer and heavier than other lenses.
From Quiz: Photography Lessons: The Equipment
Answer: frames per second
Frames per second is the rate at which pictures can be taken. The more FPS the camera can handle, the more photos that can be taken within a second. Most people don't need a large FPS for everyday photos, but it can be useful in high speed or sports photography.
From Quiz: Photography Lessons: Know the Acronyms
Answer: 1 / 1000
1 /1000 of a second is the shortest shutter speed on most cameras. This will make the picture darkest. Changes in shutter speed are measured in stops (equivalent to one aperture step). A 1/2 shutter speed is one stop darker than a 1 second shutter speed.
From Quiz: What Digital Camera Setting?
Answer: Lens
Adjusting the lens will bring something into focus (or out of focus depending on what you are actually trying to achieve with your photo). Having an object 'in focus' will ensure that the resulting picture is clear and not blurry - unless you don't have a steady hand!

Answer: Arab
This brilliant man was a polymath who worked extensively in an amazing range of fields. These included geometry, perception, mathematics and physics among others. He wrote many detailed works on same and became known throughout Europe at that time as Ptolemy II. He theorised that light was reflected from any visual body in any straight line and from any angle. He experimented on this theory using lenses, mirrors and reflections, and, almost as a side thought, he described thoroughly how this worked with his detailed description and analysis of the camera obscura. The puzzling thing is why the camera as we know it today didn't come into use far earlier than it eventually did.

From Quiz: Photography Lessons: Know the Acronyms
Answer: 1600
An ISO setting of 1600 is the most sensitive. Higher settings are used for darker situations to get faster shutter speeds. However this results in noisier shots. A n ISO of 100 is for normal daylight, 200 to 800 are often used indoors.
From Quiz: What Digital Camera Setting?
Answer: Aperture
The aperture is the opening of the lens which can be adjusted in certain cameras to control the amount of light that is let in through the lens. This affects the depth of field and exposure, with a smaller opening resulting in less light allowed through the lens but allowing for a greater depth.

Answer: a few stops down from the maximum
The minimum aperature produces the maximum depth of field, but for objects in focus maximum sharpness is usually a few stops down from wide open. For long focal length small aperture lenses used with view cameras and other types of cameras, the sharpest aperture will be at small f stops.

From Quiz: Photography: General Knowledge
Answer: Silver nitrate
Scholar, philosopher and Catholic priest, Albertus Magnus, lived from approximately 1193 until 1280. His reputation was vast and he has often been described as the greatest German philosopher of the Middle Age. He not only read and studied science deeply, he put it into practice with his many experiments, and by making detailed notes of same in all that he did. Unfortunately these experiments, which included alchemy, gave him a bit of a reputation, in a superstitious uneducated world, of dabbling in witchcraft. He managed to survive these dangerous murmurings and lived to be a ripe old age.
Silver nitrate is an inorganic compound which is the honoured ancestor of many silver compounds used today. It was extensively used in photography. Magnus discovered, in his dabblings, that when he separated particles of gold and silver from each other, by dissolving the silver, a solution of silver nitrate, which blackened the skin and captured light, was the result. Silver nitrate is used for various other functions today as well.

Answer: It decreases
Opening up the lens, creates a tighter depth of field. This means that if you photograph under low-light conditions, your focus will have little tolerance. Using more light, and a higher F-stop means that you have more freedom to zoom and move around without the need to constantly re-focus.

From Quiz: Photography: General Knowledge
Answer: Full color photographic image
Monochrome photography, often referred to as black-and-white, is generally based on the reaction between silver halides and light, which means that the image is composed of shades of grey. The stability of the image was improved by treatment of the paper on which the print was made with sepia (producing a reddish-brown range of colors) or selenium (producing a silvery range of colors). For those who could afford it, an artist could be hired to paint a photographic image with watercolors, to make them more realistic. However, the Lumieres produced the first commercial film that produced actual color photographs. The glass plate was first coated with a sticky substance such as pitch, to hold things in place; a layer of potato starch grains (roughly 10 microns in diameter) which had been dyed red, blue and green before being thoroughly mixed to look grey to the naked eye was spread thinly on the plate, then lampblack was dusted over to fill in any gaps between the grains of starch; this was covered with shellac, so that the water in the emulsion layer to follow would not damage the starch; a gelatine layer containing panchromatic photosensitive chemicals finished it off. Panchromatic chemicals reproduce all frequencies of light accurately, unlike simple silver halides, which are more sensitive to the blue end of the spectrum than to the lower-frequency colors. Their use allowed the production of realistic colors, although the images were often fuzzy, due to the roundness of the starch grains.
While the autochrome process was able to produce lifelike color photographs, its extensive filtering of the light meant that exposure times were quite long, so the convenience of hand-held cameras was sacrificed. They were quite popular for formal studio photographs, but not for family photos. That had to wait until 1936, when Kodak produced a color film roll that could be used in the same cameras as those using their black-and-white films.
