Minimize Postproduction Steps with Lighting
I would rather be fixing photos

6 easy to solve mistakes
• Sync speed too slow (blur+color shift)• Modeling light too strong (color shift)• No tripod (2 to 50% sharpness)• No lens-hood (2 to 20% more saturation)• Depending on post color calibration. The file
should be compliant when shot.

Use dependable equipement• The strobist approach
– Max power 60w/s– High dependence to batteries– No modeling light– Full range of modifying accessories (Mini-Max)– Precise settings but often complicated– TTL on multiple head varies every shot depending on
clothing , skin color and ambient light (watch why not auto)
– Can cost as much or more than a studio strobe

Use dependable equipement• The studio approach
– Needs 110v– Gives more power– Wide range of accessories– Range of prices and powers– Why a 300w/s flash cost ½ of another

Use dependable equipement
Pro 300w/s flashes• Recycling time ½ power
.4 sec full power 1.1 sec• White balance ± 2% when changing
the power min to max• White balance ± .1% on consecutive
flashes• Power ±.5% on consecutive flashes• 16 dedicated reflectors• Full range of softboxes
Commercial 200-400w/s flashes• Recycling time ½ power
.7 sec full power 1.9 sec• White balance ± 4% when changing
the power min to max• White balance ± .1% on consecutive

Auto anything is evil
• « What P and M stand for »– P stands for Passive « I let my camera take charge… »– M stands for Master « I tell my camera what to do. »– The camera is looking for 18% grey… if it can’t control my
camera it will make it happens…

My goal in life
• Shoot trusting my expensive camera– Enjoy the view– Press a button
• Come home• Happily spend 4 hours ajusting colors and
density of the kids jerseys on my new Photoshop
• And hope the parents will not put pictures side-by-side

O’Kane is a lying!
• It’s impossible….– I’ve paid $3000 for my new body!– All manufacturers say in their brochure that I will
have exact colors and tone...

3TWSAKAL:QQD3ThingsWeShouldAllKnowAboutLight: Quality/Quantity/Dispersion
• Quality– The color balance of the light
• Can be read by a color-meter• By doing a custom white balance
• Quantity– The amount of light
• Incident with a light-meter• Reflected of a grey card
• Dispersion– How the light is spread
