EV (Exposure Value)/ LV (Light value) Table

Stealing it from my own website. I have printed it out on a small card and carry it in my wallet. Very Very Handy!!!

EV (Exposure value) table

LV (Light Value) table

	LV/EV Table for ISO 100
EV	Type of Scene (Brightness)
1	Very Dark, Not Practical except for Timed Exposures
2	Very Dim, Total Lunar Eclipse, Moon Lit Scenes
3 - 4	Dim Indoor Lighting, Candle Light, Street Lights on Wet Streets
5 - 6	Brightly lit indoors, Amusement parks at Night
7 - 8	Well lit Professional Sporting Events at Night
9 - 10	Just after Sunset or Just before Sunrise.
11 - 12	Dark Overcast Daylight Scenes, Total Solar Eclipse
13	Cloud Covered Daylight Scenes
14	Average Daylight, Normal Side Lit Subjects, Partly Cloudy
15	Bright Daylight, Front Lit, Light colored Subjects
16	Bright Daylight reflecting off Snow or Water
17 - 20	Too Bright to be Very Practical
ISO Speed Stops: 12, 25, 50, 100, 200, 400, 800.
Each stop increases EV by 1 for same LV.

These two tables, in my opinion, are the best friends of a beginner photographer who is meddling with SLR settings. The rule of thumb of shooting using these tables for beginner photographers is to follow these steps:

1. Look around, find the lighting conditions that matches closely to one of the rows in LV (Light Value) table. [Skip this step if you have a light meter]
2. Choose the corresponding Light value (say L). You can get the LV directly if you have a light meter.
3. Calculate the EV from LV based on your Film's (Digital camera's setting's) ISO Speed. LV is same as EV for ISO 100 speed film. For each upstep/downstep in film speed, EV goes up or down respectively by 1. So, for film speed 200, EV will be L+1. Sounds complicated? I'll add a table for this soon.
4. Refer to the EV table and choose one of the Shutter speed/f-stop (aperture) combination that matches your calculated EV. Based on the scenario you are shooting, you might go for higher/lower shutter speed and adjust f-stop to match.
