Skyfill v1.2 released

Version v1.2 of Skyfill has been released. The most important improvements are support for 16-bit colour and AdobeRGB. You can download the release from Gitlab.

The 16-bit colour support is automatic. Feed Skyfill a 16-bit image, and it’ll output a 16-bit TIFF.

The AdobeRGB support is preliminary. It’s not auto-detected from the input file, so you have to run Skyfill with skyfill -adobergb myimage. The output image also won’t declare it’s AdobeRGB, but it will be. If you know of any way to read and write embedded colour space information in Go, please let me know!

These improvements were sponsored by Dan Rose. Thanks, Dan!


Most drones (UAVs) cannot look straight up to photograph the sky above them. As a result, spherical panoramas made with drones tend to have a gap in the sky. Some drones, like my DJI Mavic 2, can fill in this gap automatically while generating a preview. However, when I stitch the photos myself to get a better quality output, there is still that sky gap. I got fed up with having to choose between a nice sky or a nice overall image, so I did what developers do and made my own software: Skyfill.

Skyfill allows you to do fill in the gap in the sky in high-resolution images.
