How does adjusting the brightness on my LCD screen affect the photo?

Question

On my DSLR, there is a setting to adjust the LCD screen's brightness level. If I were to turn this setting up (make the LCD brighter), does this affect the quality of the picture? I would assume that something looks nice at a "brighter level", is going to look darker than I expected once I transfer it to the computer. Is there an appropriate method to compensate for modifying the LCD brightness? (maybe turn the exposure down a stop?)

Answer

LCD brightness affects your perception of the photo, not the photo.

At worst, a poorly adjusted LCD will cause you to make bad settings decisions. Make your decisions based on data in the histogram to avoid such errors.

The goal when adjusting brightness is that white areas emit as much light as a white object would reflect. This means the LCD should be dimmer in low light, and brighter in bright light.

Proper adjustment is difficult to maintain. It's impossible to perfect without hardware. Just stick to the histogram.
