Speaker : Jean - François O’Kane , The StudioCoach

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

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

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 flashes
Power ±1.5% on consecutive flashes
16 dedicated reflectors
Full range of softboxes

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…

6 easy to solve mistakes
STOP
SHOOTING
AUTO

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...

We want proofs!
Here they are.
Test on Olympus E-3

So you think it’s only my camera! This test on Nikon D-3 P P M

3TWSAKAL:QQD 3ThingsWeShouldAllKnowAboutLight: 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

First ajust for quantity
Grey card
Personal references
Pro target
Based on the histogram response

Then and only then for quality
On a grey card or on a target.

Shoot for your histogram
The histogram is the response to a lighting situation through YOUR camera.
The histogram is unique for each photo
