A tiny hole was made in a wall. Through the hole light is focused, and the outside scene is projected on the opposite wall.
In the 17th century; Isaac Newton and Christian Huygens understood the science of optics and the process of making high quality glass lenses a lot better.
Niépce added *film* to create the first successful photograph, and the modern camera was complete.
Moderen cameras have the ability to just point and shoot. Every camera has a built-in computer that handles focus and exposure so the photographer doesn't have to.
To capture a photograph light passes through the lens, into the camera, and exposing the film.
Auto Mode on a camera:
The camera will completely control flash and exposure.
Program Mode:
The camera will completely control flash and exposure.
Portrait Mode:
Attempts to blur out the background.
The camera will try to use the fastest available lens setting; which is called Aperture.
Sports Mode:
Used to freeze motion.
The camera will use the highest shutter speed possible to capture the pictures.
Reasons To Use Half-Press.
1. Faster camera response time.
2. More control over focus.
3. Encourages better compostion.
The first symbol is for disabled flash. Which means there is no flash at all.
The second symbol is for auto-flash. In most cameras this default. So, if it thinks it's needed.
If there is too much light when a photo is taken the picture will be washed out.
If there isn't enough light when a photo is taken the picture will be too dark.
A stop is a measurement of light.
How many stops brighter is the new planet if there are two suns instead of one?
Twice as bright.
How many stops brighter is the new planet if there are four sons instead of two?
Three times as bright.
Longer shutter speeds = more lightshorter shutter speeds = less light
Smaller F-stops numbers = larger openings
larger openings = more light
