  1. Why do photographers continue to define images by the limitations of legacy print technology? In modern times, I think very few photographs are printed. Most photographs are shared online. For example, here are the non-print aspect ratios for Instagram and Facebook.

    Instagram Landscape Photos have 1.91:1 aspect ratio
    Facebook Profile Cover Photo have 2.7:1 aspect ratio.
    Facebook Photo Post have 1.91:1 aspect ratio.

    When will we let go of the past and free photographers from these constraints?

    1. Thanks for the comment. I hope you didn’t get the impression I suggest to be limited by print aspect ratios only. The point was to understand your input (camera aspect ratio) and output (aspect ratio whatever media you are using, whether print or digital).
