Share Be Smarter than the Meter In our previous lesson, we learned how camera meters calculate the exposure based on the reflected light of the scene being photographed. We learned that while most newer DSLRs are more than capable of exposing a scene accurately, high contrast scenes that are predominantly bright or dark can fool our camera’s metering sensors causing an image to be under or over-exposed. In this lesson, we will learn...

Analyzing Exposure with Histogram

Share Now that we have a better understanding about exposure and how to expose a photograph using different mixtures of shutter speed, aperture size, and ISO setting, we need to learn how to analyze our exposure to ensure we’ve captured the correct amount of data in different areas of our photograph. The most intuitive way to achieve this while shooting would be to check our camera’s LCD screen as it...
