The histogram is just a bar graph of those buckets. Tall bars = lots of pixels at that brightness. Short bars = fewer pixels.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"655\" src=\"https:\/\/julioornelas.com\/blog\/wp-content\/uploads\/2026\/05\/AdobeStock_359692486-1024x655.jpeg\" alt=\"\" class=\"wp-image-309\" srcset=\"https:\/\/julioornelas.com\/blog\/wp-content\/uploads\/2026\/05\/AdobeStock_359692486-1024x655.jpeg 1024w, https:\/\/julioornelas.com\/blog\/wp-content\/uploads\/2026\/05\/AdobeStock_359692486-300x192.jpeg 300w, https:\/\/julioornelas.com\/blog\/wp-content\/uploads\/2026\/05\/AdobeStock_359692486-768x491.jpeg 768w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption class=\"wp-element-caption\">Underexposure = Shadow clipping, Correct Exposure = No clipping, and Overexposure Highlight clipping.<\/figcaption><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">The one rule to remember<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li>Look at the left edge &#8211; If the graph is smashed against the left wall and cut off, your dark areas are pure black \u2014 no detail, no texture.
