About ShutterCoach

Who makes it

ShutterCoach is made by Justin Hogan, an independent designer and engineer. Justin builds the iPhone app, the Chrome extension and this site. You can find more of Justin's work at justinthevoid.com.

"I shoot with a Nikon Zf and a 28-75mm f/2.8, plus an on-camera and an off-camera flash. I don't own a macro lens, so the close-up shots of bees and flowers I've made were all done with extension tubes, which honestly makes focus pretty hard and the depth of field super thin." — Justin

"I'm still pretty early as a photographer, most of my shots land around a 7, which is kinda the point. I wanted something that tells me what's actually off in a photo and one thing to try next time, not just a like or a 'nice shot', so I built it." — Justin

Who Luna is

Luna is ShutterCoach's AI photography coach. She isn't a person: she's the voice of the AI that reads your photo in the app. She looks at a photo as a whole first, then skill by skill (composition, lighting, exposure, focus, color and storytelling), and ends every critique with one specific thing to try on your next shot.

How the library is written

Most guides, glossary entries and articles on this site are credited to Luna, which means they were written with AI. Pages credited to Justin Hogan are Justin's own.

"Luna's an AI, so she can't have been anywhere or owned anything. I audit the library, and in October we pulled every line where she claimed a trip, a camera bag or a conversation that never happened. Gear pages say up front that they're researched from specs, manuals and owner reports, not hands-on tests." — Justin
