Exposure compensation lets you tell the camera to make a picture brighter or darker than its automatic reading. It is most useful in modes like aperture priority, where the camera chooses the shutter speed. Dial in a plus value for bright scenes and a minus value for dark ones, then check the result.
Why the Camera Gets It Wrong
A meter aims for a middle gray average. That works for ordinary scenes, but it misjudges anything much brighter or darker than average.
- Snow and white walls come out grayish, so they need a plus adjustment.
- Dark rooms or black backdrops come out too bright, so they need a minus adjustment.
- Strong backlight can leave your subject dim.
How to Apply It
- Use aperture priority, shutter priority or program mode, since compensation works with those.
- Find the compensation control. It is often a dial or button marked with a plus and minus sign.
- Take a test frame and look at the playback image and histogram.
- If the image looks too dark, add compensation in steps of one third to one full stop.
- If it looks too bright, reduce it in the same way.
- Shoot again and compare. Repeat until the tones look right.
The amounts above are first guesses, since every scene differs.
Situations and Typical Adjustments
| Scene | Typical Direction |
|---|---|
| Snow or bright beach | Plus, often around +1 |
| Backlit portrait | Plus, around +0.7 to +1.5 |
| Dark stage or night street | Minus, around -0.7 to -1.5 |
| Bright sky with a dark subject | Depends on what matters most |
Use the Histogram, Not Just the Screen
The rear screen can look different from the final image, especially in bright daylight. The histogram shows how tones are spread. If the graph is crowded against the right edge, highlights may be lost, and a pile at the left suggests lost shadows. Many cameras also offer a highlight warning that flashes over blown areas.
- Protect highlights if you plan to brighten shadows later.
- Shoot raw to keep more room for correction.
- Reset compensation after each session so it does not carry into the next scene.
FAQ
Does exposure compensation work in manual mode?
Not in the usual way. In manual mode you set shutter speed, aperture and sensitivity yourself, though with Auto ISO some cameras still apply compensation.
Why do my photos stay dark after I add plus compensation?
Check that the mode supports it, that the dial is actually changing the reading, and that no limit on shutter speed or sensitivity is holding the camera back.
The Short Version
Go plus for bright scenes and minus for dark ones, in small steps, and confirm with the histogram. Reset the control when you finish. The numbers here are general guidance for you to refine.
