I’m Kate Jonker – an underwater photographer, educator, and judge who’s been helping divers improve their photos since 2015.
I’ve taught hundreds of underwater photographers through in-person courses, online training, and dedicated workshops around the world.
My images and articles have appeared in leading scuba and underwater photography magazines, and I’ve been placed in a number of underwater photography contests. I have also judged top international competitions including the CMAS World Championship of Underwater Photography, ADEX Voice of the Ocean, DPG Masters, Underwater Photo Challenge, Scuba Diving Magazine’s Through Your Lens contest and others.
My goal is simple: to help you skip the long, frustrating trial-and-error phase so you can enjoy every dive with purpose and come home with images you’re genuinely proud of.
The Confident Underwater Photographer Online Course
A complete step-by-step system to go from hit-and-miss images to consistently confident underwater photography. Especially for cameras with manual settings (compacts, mirrorless and DSLRs)
If you’ve ever surfaced from a dive feeling deflated because your photos didn’t match what you saw underwater, this course will change that.
Inside, you’ll learn how to:
Set up your camera and housing for success
Use the right settings (and know why they work) for macro and wide-angle
Position and use your strobes for clean, even lighting
Learn all the essential macro and wide angle techniques that will make your subjects the stars of the show, and your images tell a story
Use simple composition techniques that make your images more powerful and intentional
The course is suitable for compact, micro four thirds, crop-sensor and full-frame mirrorless and DSLR cameras, and you can revisit the lessons anytime you upgrade your gear.
Hands-on underwater photography coaching in some of the world’s best dive destinations.
Join me for immersive, small-group workshops where you’ll:
Dive with a clear photographic plan each day
Receive real time feedback and coaching
Practice focused techniques like super macro, snooting, bokeh, creative lighting and techniques, wide angle and close-focus wide-angle (depending on workshop and location)
Receive feedback on your images so you improve from dive to dive
From the famous muck diving of Lembeh to other macro and wide-angle hotspots, these trips are designed to maximise both your fun and your photographic growth.
Here’s what Underwater Photographers have experienced working with me
⭐️⭐️⭐️⭐️⭐️
From generic settings to confident control
“Before doing the course, I relied on generic online settings and never really understood how to get the best out of my own camera. After the course, everything finally made sense – from adjusting my settings with purpose to positioning my strobes for beautiful lighting. I left feeling confident, inspired, and excited to use the new techniques on my next trip.”
⭐️⭐️⭐️⭐️⭐️
From hit-and-miss to consistent, strong results
“Before the course I’d captured some shots I liked, but I didn’t fully understand manual settings or lighting, so my results were hit-and-miss. After the course, I feel confident choosing and adjusting manual settings, especially balancing shutter speed and auto ISO, and my strobe positioning is much better. I can now get strong, consistent results and make the most of each dive.”
⭐️⭐️⭐️⭐️⭐️
Breaking through a plateau with expert critique
“I’d hit a plateau as a ‘happy enthusiast’ and stopped growing. In our one-on-one sessions, Kate showed me simple but powerful setting tweaks, lens and diopter ideas, and gave detailed image reviews on focus, aperture, and composition. Her honest critique is kind but incredibly helpful. I’ll definitely be booking more sessions after my next trip – highly recommended.”
⭐️⭐️⭐️⭐️⭐️
Turbo-charged progress and genuine care
“My goal was to make a quantum leap in my macro photography and really understand my TG-6 and composition. Kate quickly assessed everyone’s level and tailored her approach with great enthusiasm. My abilities have been turbo-charged to a level that’s surprised me and my friends. Kate gives so much of her time, truly cares that you achieve your goals, and encourages you to push your boundaries. I’m already waiting for the next workshop.”
⭐️⭐️⭐️⭐️⭐️
Fast-tracking your TG skills with custom presets
“This course went above my expectations. My TG-6 is now set up with custom presets I can quickly toggle between for macro, super macro, and wide angle, and I finally understand why we chose these settings. It really fast-tracks your underwater photography.”
⭐️⭐️⭐️⭐️⭐️
From frustration to significantly better macro photos
“Before working with Kate, I was struggling with focus and strobe placement on my TG-6 and felt like giving up. Her practical tips, insightful image review, and detailed notes have made a huge difference – my photos have improved significantly and I’m enjoying macro again.”
⭐️⭐️⭐️⭐️⭐️
Daily progress you can see from dive to dive
“Her workshop helped me learn so much about underwater techniques and getting the most from my TG-6 with a snoot, mini flash, and video light. The daily format of morning presentations, practice dives, and anonymised photo reviews meant I could see my images improve from dive to dive.”
⭐️⭐️⭐️⭐️⭐️
So much more than ‘just the basics’
“Upgrading from a compact to a full-frame mirrorless left me overwhelmed. I thought this course might be too basic, but I was wrong. Kate explained the fundamentals more clearly than anyone else and covered advanced techniques in a simple, practical way, unpacking the ‘why’ and ‘how’ behind every step.”
⭐️⭐️⭐️⭐️⭐️
From frustrated and stuck to excited again
“Before the course I was so frustrated with my photos that taking my camera on a dive didn’t excite me anymore. Now, with a better understanding of how the camera works and how to position my strobes for macro and wide angle, I’m really excited to dive again. This will make a huge difference to my photography.”
“Kate gave me an excellent roadmap to success and simple tricks so I have fewer decisions to make underwater. I’m excited to put it into practice on my next dives.”
⭐️⭐️⭐️⭐️⭐️
Structured learning, big breakthroughs, lasting confidence
“My biggest ‘aha’ moment was realising how close I need to be to the subject and how much sharpness comes down to millimetres. I now feel much more confident handling my strobe, snoot, and diopter, and the workshop’s logical structure helped each new skill build on the last.”
⭐️⭐️⭐️⭐️⭐️
From trial-and-error to intentional shooting
“Before Kate’s course, I relied on trial and error – sometimes I got good photos, but I didn’t know how. Now everything feels intentional. I know how to adjust my settings with confidence, compose more creatively, and apply best-practice techniques to keep improving.”
