A short guide to histogram corrections

This guide shows simple corrections that can be made with a histogram. Unlike the tone curve, the histogram provides information on a specific image. This can used to evaluate the image and make adjustments accordingly.

The histogram of the cherry blossoms shows a gap at the right and the flowers look a little grey. This is caused by slight underexposure when the image was captured.

By moving the highlight slider to the left to set the white point to where the pixel distribution ends, the whites become more brilliant and the contrast increases.

Konica Minolta History

On February 20th, 1962, John Glenn became the first American to orbit the Earth. On board his Friendship 7 spacecraft was a Minolta Hi-matic camera to record that historic event. The 4 hour, 55 minute, and 23 second flight orbited the Earth three times at an average speed of 28,000 kph (17,500 mph).

Mr. Glenn visited our Sakai camera factory in Japan on May 24th, 1963 to plant a palm tree to celebrate the occa- sion. The palm tree is still in the courtyard of the factory and stands over eight meters tall (26ft).

The camera? It was not lost. It is on display at the Smithsonian Institution’s National Air and Space Museum in Washington D.C. This and other objects from John Glenn’s Friendship 7 Mercury flight can be found in galley 210, “Apollo to the Moon.”
