Photographer Guest


Since 2013 Steamkittens has been one of the biggest names in Australian cosplay photography. Working his way around the country building a strong reputation, one con at a time, he has forged a new standard in cosplay photography with his unique approach to lighting and colour, leaving a lasting impression and influence on the cosplay scene by bringing his design background into his images and compositions.

Having worked with international cosplayers such as Yaya Han, Jessica Nigri, Kamui, Leeanna Vamp, Stella Chu and more. He has had three photos appear in Yaya Han’s annual calendar, been on the cover of US comic book Rat Queens after his photo of Astrokerrie inspired the creator to feature a cosplay cover, produced work for Ubisoft for game releases such as The Division, Wildlands and Far Cry 5, he has had work featured in the Tomb Raider 20th Anniversary book, and the DOOM 25th Anniversary video as well as being interviewed by numerous publications and websites worldwide.

From modest beginnings photographing animals at a rescue shelter (which is where the name comes from), Steamkittens is now a popular attraction at cons drawing large queues at events such as PAX (in his famous corner), regional cons around the country and for the last five years on tour as the resident cosplay photographer for Supanova. His most humbling moment was in 2018 when the New Zealand cosplay community undertook fundraising to bring him over to Auckland to start the first photo wall at Armageddon Expo.
