Shrimp in the Spotlight

It’s been a busy day.

I managed to squeeze in three dives before the Scubacam/ FiNS Magazine group arrived.

Everyone’s here now. Kasawari’s camera room is filled with photo and video equipment. And everyone’s ready to get some serious diving done.

We’re heading out for a normal schedule of day dives tomorrow…to give everyone a chance to get wet and also make sure all their gear is in good working order.

Then, from the day after tomorrow, we’ll shift to a night schedule, to explore the activity in Lembeh Strait after the sun goes down. The full moon is coming up on Monday, so hopefully there will be lots of exciting stuff happening.

Before I go to bed to rest and get ready for the upcoming week, here’s a photo I took today of a teeny-weeny little shrimp (less than a centimetre long) on a whip coral:

Strange Shrimp

Does anyone have insight into what’s going on with this shrimp?

The first thing I thought was: “Eggs”, but upon reflection, I realised that every shrimp egg I’ve ever seen has been round, not oblong.

Also, the oblong things seem to be sticking out from the shrimp’s head as well as its abdominal area…again, not something generally associated with eggs.

But I’m at a loss as to what the oblong things might be if they’re not eggs.

Help?

Selective Lighting

“Photography is light. Light is photography.”

Keep repeating this until it’s stuck in your head like a bad sitcom theme. Sing it to a catchy tune if you have to, but whatever the case…remember this.

Controlling light, playing with light, fiddling with light, manipulating light…that’s pretty much 99% of photography, once you get past the fundamentals of how to use your gear.

For instance, you’ve probably seen a bajillion images of transparent shrimp on anemones. They’re really pretty, and I must confess to having taken my fair share of normal photos of these little gems. But again…to be unique…here’s something different I tried with one such shrimp in Ambon:

I like this image. You may or may not. But you have to agree that it’s different from the usual manner in which these little crustaceans are portrayed.

So how’d I do it?

It was mid-day, about 15m down, with this two-centimetre-long shrimp sitting on a rock next to its host anemone…otherwise a pretty nondescript scene that everyone else swam right by.

Careful placement of a strobe slightly above and behind as the hard primary light + a soft fill at about three stops under from the front left = emphasis on the transparent body and intricate fuzz on the rock.

I’d like to say that I nailed this right away, but it took a dozen tries or so, primarily because shrimp like these don’t sit still. This one moved continuously, which meant the lighting changed continuously, which meant I grumbled muffled expletives continuously.

Note the pile of eggs in its belly. Yup, this one’s a proud mommy shrimp.

And here’s another shrimp everyone else swooped past…this one photographed with a single strobe to the extreme right. Had I used the normal one-strobe-to-the-right-one-to-the-left-and-blast-away approach, this image would’ve been really cluttered, as the background was filled with rocks, reef, coral…stuff.

The effect is more subtle in this image than in the top picture, but the common theme is that selective lighting makes the shot.

Selective lighting isn’t easy, but it can often make the difference between a humdrum picture and one that stands apart from the crowd.

Deep-water Shrimp

balss shrimpThe waters around Izu are seasonal. That is to say…the ambient conditions underwater change all year long, driven by the Kuroshio current, deep-water upwellings, topside conditions and a whole host of other factors.

Part of the ebb and flow of the aquatic seasons is a turnover of fauna. That is to say…different animals show up at different times of the year, so you can dive the same spot over and over again and see different stuff.

One of the popular animals “in season” now is this shrimp known locally as the balsu-ibaramo-ebi (バルスイバラモエビ), or just “balsu” for short. The proper binomial name is Lebbeus balssi.

The shrimp seems to be named after a Heinrich Balss, a German zoologist who specialised in decapods (…and I bet you thought you led an exciting life!).

Anyway, this shrimp normally lives quite deep, down to 120 metres or so. During the first few months of the year, some of these deep-water crustaceans come up to scuba depths and take up residence on pretty anemones…sparking a flurry of flashes from local underwater photographers.

Other than this, it doesn’t seem like much is known about these shrimp; a quick Google search didn’t turn up a lot.
