About the Course
Your camera can last for years — or fail you at the worst moment. The difference is twenty minutes of maintenance you can learn right now. Erik Kuna keeps his gear running through the salt spray and brutal conditions of rocket launch photography, and in this class he shares the routine behind 15 years in the field and 1,000+ sensor cleanings without a single damaged sensor. Learn to spot sensor dust before it shows up in your images, clean safely step by step, protect your lenses, and avoid the everyday products that quietly destroy cameras. About 99% of gear problems can be solved with what's in this class — and you'll handle them with confidence.
Why This Course Matters
Neglected gear doesn't fail loudly. It fails quietly: spots you clone out of every sky, contrast that never looks right, fungus blooming inside a lens until no cleaning can save it.
And the fixes photographers improvise — canned air, a shirt sleeve, a breath on the glass — often do more damage than the dirt. Erik replaces guesswork with a system built on 15 years in the field: diagnose problems like a working pro, fix what's within reach, and know the moment a job belongs in professional hands. The payoff is sharper files straight out of camera, fewer hours healing spots in post, and gear that holds its value.
Who's Teaching You
Learn from a photographer whose gear survives rocket launches
Erik Kuna has spent 15 years photographing rocket launches — an environment of salt spray, humidity, and blast debris that punishes unprotected gear. His cameras keep coming home healthy for one reason: the routine he teaches in this course.
Erik Kuna is a photographer who built his reputation shooting rocket launches, where salt spray, humidity, and blast debris punish unprotected gear. Fifteen years in the field and more than 1,000 sensor cleanings later, his maintenance routine is the reason his cameras keep coming home healthy — and here he hands it to you.
What You'll Learn
Skills you'll use every time you shoot
From your first sensor check to the quarterly once-over — here's what you'll walk away knowing how to do.
Spot sensor dust before it ruins a shoot
The white-wall test reveals every spot on your sensor, and Lightroom shows you exactly what each one is telling you.
Clean your sensor safely, step by step
From gravity and built-in cleaning to blowers and dry swabs — escalate only as far as the problem requires.
Master the dry swab
The technique that intimidates most photographers, made simple — the two-pass method Erik has used 1,000+ times without damaging a sensor.
Give your lenses the care they deserve
Erik's blower-first cleaning sequence, the truth about cheap protective filters, and why a lens hood is your best insurance.
Avoid the products that quietly destroy cameras
Canned air, household cleaners, DEET — plus the everyday item that's damaged more cameras than dropping them.
Beat humidity and build the routine
Stop mold and condensation before they start, then lock in the quarterly habit — firmware, screw checks, storage, and the light test that reveals hidden lens problems.

I am soooo pleased that I found this program. I am learning and growing by crazy leaps and bounds in my photography skills. The teaching style makes everything stick.
The classes are well done and I always learn something new. I especially enjoy the no-nonsense approach to teaching. It keeps what could be a dry topic interesting.
