1. Converting Astrophotography TIFF to 16-bit PNG
AstrophotographerBackground
An astrophotographer has a raw 16-bit RGB TIFF image of a nebula captured by a telescope and needs to convert it to PNG for a web portfolio while preserving the full dynamic range.
Problem
Standard converters reduce the image to 8-bit, causing banding in the gradients of the nebula.
How to use
Upload the TIFF file, set the Channel Mode to '48-bit RGB (16-bit/channel)', keep the page at 1, and ensure 'Preserve Safe Metadata' is checked.
Channel Mode: rgb-48, Page: 1, Preserve Safe Metadata: trueOutcome
A high-fidelity 16-bit-per-channel PNG is created with smooth gradients and no color banding.
