About Luminxel
I wanted everything in one place
Luminxel started because I was tired of jumping between calculators, spec sheets, and forum threads just to get through a shoot. I wanted the tools and the answers in one spot, and it started with a simple annoyance: reaching for a calculator every time I needed hyperfocal distance, exposure compensation, or a quick depth-of-field check.
Truth is, I wanted somewhere I could point people to that had all the information and all the tools in one place, instead of scattered across a dozen forums, spec sheets, and old blog posts. A phone app is actually in development right now, but this site, with its basic tools and guides, is where that whole idea got its start. It was the simplest version I could build and put in front of people while the app comes together.
The writing came after the tools, because half the time the harder question wasn’t what’s the number, it was why does this number matter. That’s still how I think about building this: fast, precise calculators for the field, and guides that explain the reasoning behind them, not just the steps.
No content mill, no rewritten press releases. I write and build this myself. Every guide is meant to be used mid-shoot, not read once and forgotten. The tools get updated when the math or the workflows they support change, not on some content calendar.
Calculators built for the field
Depth of field, exposure triangle, hyperfocal distance, and more on the way. Fast, precise, no sign-up wall.
GuidesThe reasoning behind the numbers
Lighting setups, color grading workflows, and technical concepts like bit depth, dynamic range, and color science, the stuff that separates “it looks fine” from “it looks right.”
BlogGear worth your money
Budget shotgun mics, tripods, field recorders, and DIT kits, picked and explained against what actually matters in the field, not spec-sheet marketing.
Want the why, not just the preset
Guides written to build real understanding, not just hand you a setting to copy.
Need an answer faster than an app
Calculators built to be faster to open than your phone’s camera app. No account, no ads blocking the number.
Want to understand their gear
Would rather know how a sensor or a lens actually works than just own one.
Luminxel is supported by ads and affiliate commissions from retailers like Amazon, B&H Photo, and Adorama, at no extra cost to you when you buy through a link. That’s what keeps the tools free instead of paywalled. Sponsored content, if it ever runs, will always be labeled as such.
