Sunday Showcase: What is a histogram?

Sunday Showcase: What is a histogram?

In short a histogram is a representation of tones in any given photograph.  Moving from left to right indicates the tonal range being its darkest on the left to its brightest on the right.  The "mountain range" represents the amount of pixels in the given ranges.  In that photo, most of the pixels are below the mid range (18% gray) with a few pixels in the mid range and even fewer pixels in the brightest tone range.

Depending on the type of shot or mood you are looking for, most people want to have a relatively even tone range throughout their photographs.  The histogram would have peaks in the mid tones then they would taper off towards both the left (dark) and the right (bright) sides of the histogram.  If you were taking silhouette type shots, the histogram would have peaks on both the left and right with little in the mid tones.

Thank you for taking the time to ready my post about histograms.  Should you have questions about photography or need to purchase equipment, feel free to contact us at Lighthaus Camera.  We have four locations across the island chain to serve your photographic needs.
