1. PHOTOGRAPHY,
LIGHT AND COMPOSITION

2. Section 1
The Story Of
Creation

3. Between 401 – 411 (Hijri calendar) –
an Arabian Mathematician ,
astronomer, and physicist of the
Islamic Golden Age “Al-Ḥasan Ibn
Al-Haytham” wrote a book talking
about the principles of optics and
visual perception “رظانملا باتك -
Book of Optics”
He discussed the first idea of what
so called “Camera Obscura”
The Story OfCreation

4. Al Hassan Ibn Al-Haytham invented the Camera Obscura, a device
that projects an image of its surroundings onto a screen through a
small opening
The Story OfCreation

6. Section 2
Camera :
Into Parts

8. Camera : Aperture
When Increasing F-Stop Number, The Aperture size will be smaller , and then,
the amount of light entered will be decreased , resulting in less bright picture

9. Camera : Aperture
When Increasing F-Stop Number, The Aperture size will be smaller , and then,
the imaginary box around the object in focus will be widened , and then
more focus to the total space

10. Summary

13. Camera : Shutter Speed
When Increasing Shutter Speed, The amount of time light can enter the
camera will be less , and then, the amount of light entered will be decreased ,
resulting in less bright picture

14. Camera : Shutter Speed
When decreasing Shutter Speed, The amount of time light can enter the
camera will be longer, and then, if there is a subject moving in frame, the
camera will capture the subject with its movement resulting in motion blur.

16. Camera : ISO
When a photon enters the sensor pixels, it’s first split into 3 Colors (Red, Green, Blue),
and then determine the voltage value (light intensity) and finally converted to a
sequence of digital numbers (zeros and ones) representing the whole image.

17. Camera : Summary
The next Question is , How can we use them all at the same time?

18. Camera : Simulation
