Shadows/Highlights Review

• if the subject is in the shadows we will meter for the shadows (most of the time)
• if most of the scene other than the subject is highlights we will split the difference between highlight and shadow meter readings
• if the subject is in the highlights and most of the scene consists of highlights, meter for the highlights
• if half of the scene is shadow and half is highlights, shoot at the calculated middle meter reading

Printing Challenge

Normal

Underexposed Negative

• thin
• not enough exposure
• EX. f8 @ 1/60 --> f8 @ 1/125

For Printing

• increase contrast (magenta filter)
• less time (exposure for print)

Overexposed Negative

• thick; too much exposure
• generally have to decrease contrast to print as normal
• increase printing time
• EX. f8 @ 1/60 --> f8 @ 1/30

SABATTIER EFFECT

Discovery: Over a century ago, a French doctor and scientist, Armand Sabattier, discovered what he called a psuedo solarization reversal effect.

• today it is often erroneously referred to as solarization, but there is a distinct difference between solarization and Sabattier
• technically solarization is the reversal of an image on film by extremem over exposure
• the Sabattier effect is the partial reversal of an image on neg or print that occurs when the film or print is re-exposed to light in the developer.

Chemical Process

• to create a print for Sabattier, first find proper contrast and density for the particular image
• now boost the contrast to around 140 magenta and print the image lighter than normal
• place print in developer for about 10-15 seconds, stop developer and and re-expose the print for about 3-4 seconds
• continue developement (this time really varies)
• stop and fix as usual
