To take good photos, it is necessary to understand the parts of a camera
and how they work to take photos. To learn more about cameras click on
the following link and click on each category.
1. Explain the “camera obscure” effect. How is it achieved?
In ancient times, Greek and Chinese philosophers discovered a curious optical effect, and it worked like this:
2. What invention during the 17th Century helped man get a step closer to creating the modern camera?
In the 17th century, the modern camera came one step closer when Isaac Newton and Christian Huygens perfected the understanding of optics and the process of making high quality glass lenses

3. What were the parts of the first modern camera invented by Niepce?
Soon there were small, portable camera obscures, but an important piece was missing..
4.What do modern digital cameras have in common with Niepce’s camera?
4.What do modern digital cameras have in common with Niepce’s camera?
New cameras are very easy to use, just point and shoot. The camera's
built-in computer handles focus and exposure so you don't have to.
5. What do digital cameras use to capture an image?
So what has changed? The most recent revolution in photography is the invention of digital film.

6. What is the difference between the Auto Mode and the Program mode?
Old fashioned cameras have one mode.. manual. Camera settings would have
to be figured out by the photographer, along with focus.
7. What is the Portrait mode used for? How does it work?
Of all the shooting modes, Auto/Program is probably the most useful.
Most people don't really want to learn about how a camera works, and
point and shoot photography is the perfect solution.
The fully automatic Auto or Program mode is the default
for most modern cameras. The photographer can simply aim, press the
button, and almost be guaranteed a great image.
8. What is the Sports mode used for? (not just sports) How does it work?
While Program is the most important for everyday use, most cameras
have dozens more.. it's like having an assistant photographer inside
your camera who tries to figure out what you need.
9. Why should you do a half press on the trigger button?
Most of the time, the inside of the camera is totally dark. When a
photograph is taken, the camera opens and light from outside floods in
through the lens. Light is projected onto film to make the exposure.
10. What does this symbol mean?
When would you use this?

12. What happens to your photo if there is too much light?
Aperture, shutter, and film settings are all divided up into "stops", even though the numbering systems are different.
13. What happens to your photo if there is not enough light?
14. What is a “stop.”
In order for an image to be captured on film, it must be exposed to
light. The camera has two settings that control light, and they work
very similar to the human eye.
15. How many stops brighter is the new planet if there are two sons instead of one?
The shutter blocks all light from exposing the film UNTIL you press the
button. Then it quickly opens and closes, giving the film a brief flash
of light.
16. How many stops brighter is the new planet if there are four sons instead of two?
Before light reaches film, it must pass through an opening called an
"Aperture". The aperture is like a pupil. You can control the aperture
by setting the "Aperture Opening", also known as an F-Stop.
17. What affect does a longer shutter speed of have?
Determines HOW LONG the shutter stays open.
18. What affect does a shorter shutter speed have?
Like the pupil in a human eye, the aperture on a camera controls light.
It does so by closing up to restrict light, and opening up to let it through.

19. What does the aperture control?
Exposure is about different combinations of shutter and f-stop settings.
These combinations can drastically affect the finished picture. For
example, the following three pictures have been given an equal amount of
light, but the f-stop and shutter combinations make each one unique.
20. When adjusting the aperture, how can you increase the amount of light?
Since f-stop and shutter are both measured in stops, keeping balance is
easy. If you take away 2 stops from the aperture, you can give 2 stops
back with the shutter and end up with the same exposure level.
