Light Metering Using Sekonic Meter

A. Sources of Light

1. Ambient Light (Sun.Moon and lamps)
2. Flash Light

B.
Metering Types

1. Incident Metering (Direct to subject)
2. Reflected Metering (Spot metering)

C.
Metering Mode

1. Ambient Mode
2. Flash Mode
a. Auto reset cordless flash mode (if we don't want to use sync cable)
b. Cord flash mode (when using sync cable)
c. Wireless flash radio trigger mode

When using Flash mode always entering ISO & Shutter speed


Notes:

A.
Camera create appropriate exposure using 3 things:
Exposure Triangle

1. Aperture
2. Shutter speed
3. Iso

B.
Using light meter
1. If We enter Aperture and ISO and light meter give the shutter speed
2. Or we enter ISO & Shutter speed and the meter give the Aperture
3. If in studio we metering strobes , enter Iso and shutter speed so the meter will give us the aperture

JTL s45m Master AC slave bulb

JTL's AC slaves are great tools for providing even fill light in conjunction with your master flash unit. They screw into any standard AC light socket and do not require a sync cord, so you won't need a complicated lighting setup for them to function (although a sync cord can be used with the S-45, if it's needed). The flash tube's long life means that you'll be creating bright, consistent light for years to come.

Choosing camera metering Modes

1.Multi zone /Matrix/Evaluative metering. several selected locations throughout the frame are used to determine the exposure.
2. Spot 1 to 5 % of the center of viewfinder
3,Partial : 10 to 15 % of viewfinder
4. Center weighted average : scene is read about 60 to 80 % of viewfinder

White balance setting

White balance setting:

1. Automatic
2. Daylight
3. Cloudy light
