The title is quite easily explained. When I'd started underwater photography, I had only one strobe. I've recently added another. This was my first trip out with dual strobes. What a difference! Previously, a picture like this one would be impossible. There would be reflections and the shadows would be very harsh. Now I can illuminate the face of this white-eyed moray nicely. Balanced.
I do not regret waiting so long to add the second strobe. Having only the one strobe taught me a lot about strobe positioning, strobe output, lighting, reflections and backscatter. It prepared me for two.
I must admit to cropping this picture by a good amount. The original picture has the whole eel's cave entrance and quite a bit of the eel. I just thought the picture presented this way really improved it by leaps and bounds. I realised it when I zoomed in on its eyes to check the focus of the picture. And oh yeah! it's in focus! Look at the eyes carefully enough and you can see the lens in the eyes. This isn't even a big eel. Just a baby white-eyed. I try not to crop my pictures if I can help it. This is only the second picture I've cropped since I started.
