Site design / logo 2022 Stack Exchange Inc; user contributions licensed under CC BY-SA. If youve cropped your image relative to the full frame size of your format, then the actual CoC changes because the magnification ratio from the image to the final print changes. Thank you for this post, its been very helpful! I compared the HFOV measured in the images with those given by your calculator, so that I could characterize its estimates. And when I plug sane inputs into your calculator I get totally different weird and wrong answers with negative areas of view and stuff. Since in most cases, the width is the long edge, and since the subjects are portrait kinds of images, this usually works fine. As a workaround, until I can figure out a better solution, you could trying using a custom sensor size with the width and height reversed. The new semantics, when combined with the recommended keyboard interactions provided in WAI-ARIA Authoring Practices [wai-aria-practices-1.1], will allow alternate input solutions to facilitate command and control via an alternate input solution.. WAI-ARIA introduces navigational landmarks through Does the distance in this calculator refer to distance from image sensor, distance from the end of the lens, or some other distance? ] link next to the displayed Circ.
