About
About Sunray Image
Sunray Image is an independently run informational website about digital images, video formats and practical photography.
We write for people who want to understand what is happening between the lens and the file: how sensors record light, how pixels are arranged and compressed, how formats are converted, and how to make better photographs with the equipment you already own.
The site is purely editorial. We do not sell, distribute or support software, and we are not the successor to, or affiliated with, any former software company — including the developer of YUVTools. Our YUVTools page is a reference guide, not a product page.
What we cover
Image & Video Tools
How viewers, analyzers and comparison utilities work, and how to choose the right one for a job.
Formats & Conversion
Pixel formats, color spaces, containers and the math behind converting one to another cleanly.
Practical Photography
Field-tested guidance on light, exposure and composition, written for people who actually shoot.
Editorial principles
Original work
Every article and image on this site is created for Sunray Image. We do not republish archived material from other sites.
Explain, don't mystify
Technical terms are defined where they appear, and formulas come with worked numbers.
Honest about limits
Where a topic depends on specific hardware or software versions, we say so rather than overgeneralise.
