Hello, Until this morning both of my strobes (YS-D3 lightning mkii) were firing fine. Today one of the strobes has stopped firing, it powers on, charges up etc - everything seems ok but my shutter/trigger isn't triggering the flash. My attempts: I've swapped cables with the working strobe and both fibre optics fire the working strobe. I've swapped batteries and same as above. So the working strobe can be fired with both fibre optic ports on the housing, both fibre optic cables and both sets of batteries. I can trigger the dodgy strobe with my phone's flash into the port and I can trigger it by running a fibre optic between the 2 strobes. Any ideas what could be causing the strobe not to fire normally? It doesn't seem to be an issue with the trigger (S-turtle 2 manual trigger) the cables, the ports or the batteries. I did find that when I'd turn it off for a few minutes and turn it back on it'd instantly turn red as if it was ready to fire, but with no red flashing light/recycle sound. I don't shoot bursts on high power or anything too intensive for the strobes so it's unlikely that it's fried I'm in Raja Ampat for the next few weeks so hopefully can find a solution to get both working again!

Just wondering if anyone is selling a Nauticam housing for Sony A1. Ideally UK/Europe based.

UK buyer but will pay postage worldwide

Just wondering if anyone knows of any upcoming competitions, either underwater focused or any with an underwater category? I know UPY usually comes up around this time of year, but this leads to another question - how do you find out about/keep track of competitions and their submission dates? Cheers, Evan

My name's Evan, I'm a marine biologist and wildlife guide from Ireland. I got into underwater photography whilst working as an instructor in Thailand 4 ish years ago. I now work as a guide in Scotland and tend to stick to natural light whilst freediving. I shoot on a Sony A7r iii and mostly wide angle but do enjoy hunting macro subjects. I'm here to pick up a few tips to improve my photography, connect with others, and also to buy / sell second hand gear. Feel free to check out some of my shots @of____earth Thanks for reading :-)
