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
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
STOPSHOOTING
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

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
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
Shoot for your histogram
Process for the batch
• You only have 2 choices– Do the SAME mistake all along and 1 click correct
• Set M• Look in LCD• Shoot a reference card• Shoot the kids• Process on computer
Process for the batch
• You only have 2 choices– Expose and white balance at picture taking

By the way here are some of my athletes
