    Here is a HDR image of the waxing crescent Moon from last night with my Sony ZV-E10 and Canon 400mm f/5.6 USM lens. The image is composed from five photos taken in 0.3 EV increments then layered and aligned to create the HDR (high dynamic range) image. Fancy words for saying I made an image that more closely resembles what our eyes can see as far as the dynamic range of light. Our eyes see a greater dynamic range of light than consumer cameras can generally capture in a single photo, but we can capture multiple photos at different light settings and combine them into a single image to increase the dynamic range of light.

    The original image was an HDR composite created from 5 photos. That night I also shot a short video with the same equipment and lens using 30p 100M. The image below was created by using 30 frames of video exported after post processing the video in DaVinci Resolve 18.5. I loaded those 30 frames into Photoshop as a stack, had it auto-align them and transform them into a smart object. I then applied a bit more post processing in PS. The result is a cleaner, less noisy image with more detail. Unfortunately it contains less dynamic range because it is from a video rather than 5 photos with varying EV settings.

    Here is a single frame from the video:
