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!!!
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:
EV (Exposure value) table
| f 1.4 | f 2.0 | f 2.8 | f 4.0 | f 5.6 | f 8.0 | f 11 | f 16 | f 22 | f 32 | |
| 1 s | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
| 1/2 s | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 |
| 1/4 s | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 |
| 1/8 s | 4 | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 |
| 1/15 s | 5 | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 |
| 1/30 s | 6 | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 |
| 1/60 s | 7 | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 |
| 1/125 s | 8 | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 |
| 1/250 s | 9 | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 |
| 1/500 s | 10 | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 |
| 1/1000 s | 11 | 12 | 13 | 14 | 15 | 16 | 17 | 18 | 19 | 20 |
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:
- 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]
- Choose the corresponding Light value (say L). You can get the LV directly if you have a light meter.
- 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.
- 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.
