Great report and pics, Adrian and Marc both. Looks like you guys really had a slam dunk of a weekend.
Marc, if I may ask what camera are you shooting inside that Ikelite housing? You did a great job with the ambient light shots - the colors, especially the background, came out surprisingly well without artificial strobes. What ISO and white balance settings are you using? They really have an interesting look to them.
Well done all ... especially the Optimeg plant!!
