Triangle of Exposure

1. Aperture: Control of how much light is let through. Also controls depth of field
2. Shutter speed: how fast the shutter on the camera moves. Slower shutter speeds will allow for more motion blur
3. ISO: The standardized system for measuring film speed.
4. Depth of field: the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image
5. Motion blur: the streaking in an image that comes from an image being captured for an extended time period while it is moving
6. Noise and light sensitivity: Noise is random (not present in the object imaged) variation of brightness or color information in images, and is usually an aspect of electronic noise. Light sensitivity is the level of light that the camera shows in the picture.

Print Photography VS. Digital Photography

Print Photography:
Pros:
High Image quality
Can better utilize natural lighting
Final work is physical
Generally taken more seriously in art community
Special filtering effects are more challenging, ergo, more impressive
cons
Film is easily damaged
Photographers won't recieve feedback as quickly
Require more skill
Sometimes require expensive development chemicals
Work can't (as easily) be posted online

Digital Photography
Pros
Effects can be manipulated digitally with computer
Finished photos can be saved and published digitally and online
Cameras are generally not as easily damaged
Photographers can receive quick feedback
Don't have to be developed
cons
Lower quality photos
Cameras tend to have longer shutter lag
Digital zoom creates a blur that doesn't come with optical zoom
Less skill makes final product seem less impressive
Higher initial cost
