The LCD on your digital SLR is fabulous.
But do not use it to judge exposure, for one main reason: it is not objective. Its apparent brightness is affected by ambient light as well as by your LCD’s brightness settings, and this can easily lead you astray. I see this all the time in classes. “Why is my camera overexposing every shot?” is usually answered by “it’s not, but you have set your LCD to full brightness”.
- Expose well (use the tips on this blog; learn exposure compensation; learn to use the spot meter).
- Use the histogram to judge whether you got it right.
- When using the LCD, use a Hoodman Hood Loupe.
- Set the LCD to “average” brightness.
I like to “expose to the right” – your preference may be different. Either way: do not judge a photo by the LCD on the back of your camera.
