From Auto to Manual
Auto: Point the Car - Step on the Gas - easy. Not too enjoyable, but easy.
Manual: Point the Car - Work the gas, work the clutch, work the shifter - complicated and easy to have bad results...but will be more fun in long run.

The STOP!
A Unit of Measurement: speed/length/weight
light quantity: a STOP of light
A STOP: Not a fixed unit like “inch” or “pound”
Its defined in relative quantity:1/2x or 2x

ISO film speed
• ISO measured in Stops, i.e. ISO400 is one stop greater than ISO200 which is one stop greater than ISO100;
• Digital Sensor Sensitivity to Light;
• Higher ISO, Less Light required for equivalent exposure;
• Higher ISO the more noise introduced to the image;
Creator Moment: Is Noise Bad?

Some Rules on SS
• Minimum Shutter Speed to hand hold:
• 1 / focal length, i.e. 24mm focal length can be hand held at 1/24th of a second.
• BUT at extremes rule fails: I’ll hand hold (when it matters) no less than 1/50 with lens 70mm or less.
• 200mm and above: at least 1/200th

Some Rules on F/Stop
• Overall lens sharpness drops off at lens f/stop extremes;
• Every lens has its own unique “sweet spot”
• Need to figure that out over time
• Sometimes I break the rule
Creator Moment: Does anything in the image have to be sharp?

What Image?• Bits: 16 vs 8
• 16 gives you more editing power, and eats more more memory (twice the file size).
• Resolution:
• 72 ppi is perfect for anything online or on screen display, little editing power;
• 300+ is appropriate for print, substantial editing power.
