    No empty zones and no peaks on both ends of histogram...

    And there should not be any flat baselines at either end of of the graph.

    This video explains a lot…. https://youtu.be/htqrTTSZp-M

    Several years ago, there was a topic on here that referenced some good resources for the histogram.



    Unfortunately, this first guide by Paul Nichols which is probably 10 years+ old but it taught me everything about histograms is no longer available online - maybe some of the others readers might have more information on that, but the other guides on that topic will definitely help.

    Understand Histograms

    Hi,

    Just wanted to ask, how do you make sense of the Histogram and the RGB Histogram for submissions? What am i supposed to look for? Is there any resources or any recommended videos that explains this?

    Also, (Probably will remove soon) refer to the queud photo: https://www.jetphotos.com/viewqueued_b.php?id=10151324
    In the RGB histogram, what does the big spike starting in the left mean? I'd like to know so I can try to decide for myself what else would be grounds for a rejection.

    Thanks
Working...
