Shooting Jellies

My favorite photo op in the jelly fish department

My favorite photo op in the jelly fish department

I have often said that if I had to have an office with no window, I would want a huge aquarium of well-lit jellyfish.  They may not be cute and I can’t say they make me laugh, but there is something indescribably soothing about their movement through the water.

They also make for a fascinating photographic subject, if a difficult one.  I imagine if I were a diver, I might have less difficulty, but then I realize I would probably end up among an entire smack of jellyfish (yes, I googled to find out what you call a group of them–seems appropriate given what it feels like to be stung) and wide up with some fatal amount of jellyfish stings.  Plus, underwater shooting creates its own set of difficulties.

Fortunately, the Tennessee Aquarium offers far safer photo ops of a wide variety of jellies.  My personal favorites are the West Coast Sea Nettles when it comes to shooting.  They have lovely colors, they’re large and I tend to get a little less reflection off their tank since it’s flat and the lighting is relatively good.  Of course, it’s still a bit challenging to get a sharp photo.  Besides the thick glass between my lens and the jellies, the lighting is still dim and the amount of movement happening throughout the body of the jelly requires a relatively fast shutter speed.  At the same time, they are 3-dimensional, which means greater depth of field is required for a shot that has more than one small portion in focus.

By shooting this at ISO 10,000, I was able to use a 1/100 of a second shutter speed.  By shooting between 32-64mm focal length, I got better depth of field at an f/5.6 aperture.  The head of the jelly (if that’s what you call it) gets a bit fuzzy in the brightest parts–I’m not sure if that’s due to movement or the high ISO setting.  All-in-all, I’m impressed by the lack of noise at a 10,000 ISO setting–my 40D would have been noisier than this at 800 ISO.

Looking at the group of nettles together, I try to imagine what it would be like to encounter a large smack in the ocean

I also managed to remember that my camera will shoot video as well.  Since it’s the movement of the jellies that fascinates me the most, I figured this was a good time to use them.  Unfortunately, just because my camera can shoot video doesn’t mean I can.  As this video demonstrates, I haven’t learned even the basics of how to get a decent video yet–although I do think I have good taste in background music ;-).  All in time, I suppose.

Next trip, I will take a macro lens to see if I can get some good shots of the smaller jellies and their cousins.  The Sea Walnut is little guy I particularly want to shoot–their bodies reflect light in such a way that it looks like colorful lightening is going off inside them.



New Tricks

Menacing yet living peacefully with so many fish

Menacing yet living peacefully with so many fish

The Secret Reef display at the Tennessee Aquarium is yet another place where one can easily lose track of time.  The tank extends from the top to the bottom of the Ocean Journey building with ramps that lead visitors deeper and deeper until you end on the ground floor with the reef over your head.

This provides ample viewing opportunities to see animals at all depths of the tank.  If the sea turtle happens to be surfacing for air, you can see it at the top.  If it happens to be eating, you’ll see it a couple floors down, and if it decides to take a nap, you might also see it on the bottom.  If you’re really lucky, you’ll get to see it at all the levels.

The sharks seem to float through the center of the tank, mostly.  They are the most ferocious looking of the creatures in the tank, yet they float docilely by the rest of the members of the community.  I have to imagine that they don’t eat their neighbors–the aquarium couldn’t afford to keep replacing them.  My theory is that even a species that’s been around since the time of the dinosaurs can learn new tricks when its well fed.

My other favorite residents are the two green sea turtles.  Stewie is a giant–or at least he looks giant compared to the size of the rest of the inhabitants.  Every time he floats into view I think of the Disc World series by Terry Pratchett.  For those of you who are not geeks, this is a sci-fi/fantasy series of books that take place on a planet that rides on the backs of 4 elephants who are, in turn, riding on the back of a giant sea turtle who swims through space.  Presumably he’s much larger than Stewie.

When I see Stewie, I find myself thinking perhaps it is not completely preposterous that a planet might be propelled through space on the back of a sea turtle.  Although, the books are, of course, tongue-in-cheek.

The other sea turtle bopping about in the secret reef tank is Oscar.  Oscar has a bit of a story.  The first time we ever saw Oscar, he was wedged under a rock at the bottom of the tank and appeared to be dead.  Apparently visitors report a dead sea turtle in the tank every time Oscar takes a nap (which is a daily occurrence).

In reality, Oscar was rescued following a collision with a boat.  He lost most of his back flippers and ended up with air trapped under his shell.  As a result, he floats abnormally for a sea turtle.  So, he wedges his head under a rock and his rear-end floats toward the top, looking very odd indeed.  Fortunately for Oscar, he’s doing quite well at the Tennessee Aquarium and has quite the fan club.

Who says you can’t teach an old turtle new tricks?

Poppin’ Penguins

These guys played statue for me

These guys played statue for me

I love penguins.  I suspect this started in childhood.  Mr. Popper’s Penguins was one of my favorite stories.  I fantasized for weeks about how to build a giant ice sculpture for the penguins I wanted to live in our basement.

Imagine my surprise when I saw my first live penguin display and there was no ice.  Seems penguins do just fine without it–at least the species in the aquariums and zoos I’ve been to.  The important ingredient seems to be making sure they have a place to swim.

My adult fantasy has nothing to do with taking penguins home with me (taking care of a dog is enough responsibility), but with getting a great shot of one of them popping out of the water.

It fascinates me how they can build up so much speed underwater in a relatively short distance that when they decide to beach, they can propel themselves straight up into the air and land on their feet.  It’s the equivalent to flaring a hang glider to land, except that they are moving in the opposite direction of gravity and through the resistance of water.

Alas, the penguins do not accommodate me.  In all of my visits to the Tennessee Aquarium, I have either been behind crowds of children and couldn’t get an angle on a popping penguin or the penguins weren’t popping.  On our latest visit, they weren’t popping.

One of the few penguins in the water glided along slowly

Rather than demonstrating their underwater and water-exiting talents, they swam rather lazily like they’d just eaten and were afraid of getting a cramp.  They waddled about in their penguin waddle way and made noises at each other up on the surface.  This was amusing in and of itself.

Any of the young penguins that had recently hatched the last time we visited had either become full-fledged, and undistinguishable, adults, or been sent elsewhere.  Gone were the rock nests and none of the penguins were stealing rocks from others.  They were, however, stealing fish.

They cackled at each other and sword-fought with their beaks, although no one actually tried to land a jab.  They seem to be arguing about the rations each bird was entitled to from their recently served meal.  From the looks of them, there’s plenty of food to go around.

This guy really wants all the fish

I particularly enjoyed watching one getting ready to enter the water.  He waddled over to the edge, slowly raised a foot like he was going to do a dramatic dive into the water, and then hopped down to a lower ledge that was all of 3 inches below the water line.  Apparently he wasn’t up for a swim yet, but felt like wading.

One of these days I’m going to take a day off when all the kids are in school and go sit myself in front of the penguins all day long until I catch one of those little men in tuxedos popping out of the water.

In the meantime, I might have to go re-read Mr. Popper’s Penguins.


Open Mouths

Continuing our visit to the Tennessee Aquarium, I discovered a topic I never expected to write a blog post about.  Let’s talk about mouths for a moment, shall we?

Some mouths are terrifying.  Think Jaws.  Think Tyrannosaurus Rex.  Now, think Alligator.  Not so very different, in my book, than thinking about being bitten by a dinosaur.  After all, the American Alligator actually did live with the dinosaurs.

Even sleeping the alligator looks menacing

Even sleeping the alligator looks menacing

The relatively small Alligator that lives in a rather cushy environment in the Tennessee Aquarium by Alligator standards (I should think), chose a rather interesting spot to hang out for an afternoon nap.  The only thing that would have made his choice of places to sleep better would have been if the glass would have been antiglare.  Since I can’t imagine the aquarium staff has been training the alligator to nap where it can be viewed up close, I’m guessing this little nook was designed to be exactly what an alligator looks for when it comes to nap nooks to increase the odds that visitors would get to admire this guy’s teeth up close.  They sure are white.  There is something disturbing about an animal whose teeth are so prominent they don’t fit inside its mouth when it’s closed.

I think this might be as close to cuddling as alligators get

I think this might be as close to cuddling as alligators get

Catfish are another creature that has a scary mouth.  They also co-habitated with T-Rex.  Perhaps I have stumbled upon a pattern?  While the teeth of a catfish may not be so prominent or sharp as the alligator’s, there is just something downright menacing about the way their mouth looks to me.  It comes as no surprise that there are several types of catfish who have been rumored to kill people (although not substantiated).  This catfish was enormous.  While not even close to the top of the scale for big catfish, he seemed big enough to swallow a small child whole.  I don’t think this catfish actually has any interest in eating small children, fortunately.  His markings make me think of my dog, making him a whole lot cuter than most catfish.

This guy doesn't look so scary with his back turned

The next in our series of mouths is a crazy turtle.  An alligator snapping turtle, to be exact.  Unfortunately, his lure doesn’t show in the shot (through thick glass), but this guy hangs out with his mouth open and wiggles a lure that is part of his tongue to attract fish.  An underwater fisherman.  I’m just guessing, but I suspect this guy may be even older than the alligator–he looks like a rock.

I don’t recall the name of the next open-mouth participant in today’s post.  I assume he is gathering something edible by filtering the water, but he kept swimming around with checks billowing like sails.  I missed a shot of the inside of his mouth reflecting light and shimmering like a silver bowl.  He just glided by with his billowing mouth below his paddle of a nose looking some sort of bizarre submarine.

Otters and Smiles

There are certain things in life that make it impossible not to smile.  A toddler laughing.  A dog wagging like mad.  An amazing sunset.  And otters.

Who can possibly watch otters at play without smiling?

The Tennessee Aquarium has otters in their River Journey display.  I have been to the aquarium at least a dozen times in the past year and a half.  The otters have always been sleeping.  Otters sleeping are cute, but not quite so provocative of a smile as when they’re playing.  Discovering they were wide awake and having a ball on our recent visit with friends was quite a joy for me.

One might think the otter needed a rest, but he really was looking for a diving board

This might have been a great time to switch over to the video mode on my camera.  But, alas, I keep forgetting it will shoot video.  So, I have created a video from a series of rapid fire stills instead.  I didn’t actually shoot with the intention of making a video, so there are gaps.  The biggest gap is that I missed when they were swimming upside down.  How is it that otters can swim upside down as easily as right side up?   According to the National Geographic website, they can close their ears and noses.  I imagine that would be a big advantage during graceful rolls and swirls through the water.

The first time I thought I saw a river otter in the wild was in Colorado.  As it turned out, it was a beaver.  When it smacked its flat tail against the water at us, I realized my mistake.  In retrospect, a sea otter would be closer to the size of a beaver than a river otter, so I really should have known it was a beaver.  Seeing a beaver was pretty exciting, but I’ve always wanted to see wild otters at play.  So far, the closest I’ve come is when we saw river otters in a mountain lake near Mt. Hood in Oregon last fall.  They were fun to watch, but we were a bit far away to get to see much besides their heads when they would pop back to the surface after diving for fish.

River Otters are one of the many creatures I envy.  They are perfectly equipped for their lifestyle.  They have all the special features they need to not just survive through cold winters and hot summers, but to thrive in them.  They embrace their lifestyle with verve and frolic through life.

Of course, there are downsides.  For one, they are apparently very vulnerable to environmental pollutants.  For another, that warm, waterproof coat is something humans want to have.  They had disappeared from much of the country as a result.  Fortunately, through reintroduction and habitat management, they’ve made quite the comeback and are even considered a nuisance in some localized areas.  However, there are still many parts of the country that have very few river otters.  These must be the parts of the country I usually go hiking in.  I keep hoping, though.


Sharing Wonder

Why is it that going to the same old places seems like a special treat when sharing it with someone for the first time?  While our friends were visiting after Christmas, we took them on a whirlwind tour of the Tennessee Aquarium.

These little guys are so fascinating to watch, I can’t imagine what soulless person could harvest them

I haven’t been to the aquarium for a few months now, but I really thought I’d seen everything there was to see there.  Yet, seeing it with someone new always makes me look more closely.  I go into the experience with nervous anticipation–I want my friends to be wowed.  I want to feel the pride of a “native” about the really cool things my chosen town has to offer.  I don’t know if this is because, in part, I feel guilty about having moved away and I want my friends to understand what is so attractive about this place.  But, honestly, I felt the same way taking visitors to interesting places in Columbus.  I don’t know what it is about a town that makes a person identify with it.  Is it just the desire to show someone a good time?  Or is there really some underlying insecurity that makes me feel like if they think the aquarium is lame, I’m also lame because I love it?  I think about going out to eat with people who recommend a restaurant and choking down barely edible food with a smile because I like these people and I feel like it would somehow be a personal insult to them if I admitted that I hated food they loved.  What I don’t quite get is why we care (excuse me for presuming I’m not the only one who does).  Some people prefer chocolate ice cream while others prefer vanilla.  It’s not a comment on someone’s value as a human being.  Yet, it’s so much more fun to share something with someone when they really enjoy it than when they just fake it.

I’m happy to report Georgia and George genuinely enjoyed the aquarium–they made it more fun for us, too.  Their fascination with the floating jelly fishes made me appreciate the jellies all over again.  Their enthusiasm about the river and ocean tanks made me see it like it was the first time.  Georgia’s willingness to touch a sturgeon had me dipping my arm into the tank right along side her.  They don’t have scales like other fish–they feel very smooth.

We also caught part of a Ranger Rick show that featured a bird I’ve never seen before–a Trumpeter Hornbill.  For those of you who do not remember Ranger Rick, he was a cartoon raccoon and the name of a children’s magazine about nature.  The aquarium has Ranger Rick shows for children, but I didn’t see many kids in the audience.  The most amazing thing the Hornbill did was catch a grape in mid-air that was tossed just a few feet in front of it.  They need better lighting for photos, but it was still pretty cool.

The Next Parade

Well, it’s that time again:  the next Christmas parade.  If the Mainx24 parade was challenging with it’s bright daylight, the Starlight (aka Street light) Parade was even more with its very dark setting.

With my 5D Mark III on a tripod with a ball head attachment that also allows for panning, I was able to pan with the parade.  This is the only way I was able to get anything in focus.

I started out with a non-panning shot of the crowd in front of the Tennessee Aquarium.

The Tennessee Aquarium has glass pyramids on its 3 separate buildings.  The two buildings in the image each have two lighted edges.  From some angles, you can see all four lighted edges.  From other angles (like the view from our balcony), one of the lighted edges disappears behind the front glass surface.

This is a fun phenomena when walking along the riverfront.  If you start at the West end of Renaissance park, all four edges are visible.  As you walk East, the one edge gradually disappears from view.  I have thought about putting a mark on the sidewalk at the point where the one edge disappears completely.  I might be the only one who notices.

The crowd was getting pretty excited by the time the parade started.  People kept surging into the street to see what was coming.


What was coming was a fire engine, fortunately with its sirens silenced.

The Howard High School marching band soon followed.  They had also marched in the Mainx24 parade.  I found myself wondering if they have a shortage of funding for band uniforms–their drum corps was wearing matching sweatshirts and beanie caps.

They stood in front of us for a long time, waiting for the traffic in front of them to make the turn ahead at slow speed.  The drum corps continued to drum a beat and the rest of the band swayed in time.  The young man to the left seemed to be grooving.  It was fun to watch.


While the band waited to move on, the horn section swayed to the beat of the drum corps

The same dog shelters that were at the Mainx24 parade were also at the Starlight Parade.  However, they opted for more vehicles and fewer dogs.  What they lacked in numbers, they made up for in size.

Instead of mini-cheerleaders, this parade had twirlers.  I’ll share some photos of individual twirlers later, but this was their float with the tiny-tot-twirlers riding and waving instead of twirling.  I imagine this was a wise decision.

A group of girl scouts walked by next.  they all wore red pajamas and santa hats.  Most of them seemed to be busy talking amongst themselves, but one girl scout gave me a long smile while I panned with her.


While the rest of the girls scouts chatted, one girl scout smiles for the camera

Through all of this, Tisen clung to Pat’s side at the curb while I kneeled in the street shooting.  Doesn’t seem like he likes parades much.

It Bears Repeating

The Tennessee Aquarium not only offers a diverse collection of aquatic life, but they also have these fantastic river cruises.  Pat and I took the 3-hour tour (but the weather didn’t get rough) last September.  It was such a great experience, we decided to do the 2-hour version with Pat’s family during their recent visit.

In my mind, there would be a cool breeze blowing across the river that would somehow wipe the 106 degree heat away and leave us feeling cool and refreshed.  Or, worst case, we’d be in a cool air conditioned cabin.

Allow me to mention that when we took the sunset tour in September, it was about 30 degrees cooler and it was, well, sunset.  Between the extra 30 degrees and the very direct sunlight during the brightest part of the day shining through a mostly glass-enclosed cabin, the A/C had a little trouble keeping up.  Oh, wait, I forgot to mention that in September, there were 13 of us on the cruise.  This time around, there were about 70 people sitting together sweating.

The circumstances kept us from regretting that it was only a 2 hour cruise, at least.

On the plus side, we had a knowledgable and hysterical guide.  He kept us all laughing in spite of the heat–he may have missed his calling as a stand-up comic.  We also learned quite a bit–I think I’ve now been on enough of these tours and to enough historic sites that the history of Chattanooga is finally starting to sink in.

We also saw a lot of Osprey–something we didn’t see in September.  I was so excited by the Osprey that I stood up on the deck the entire time we were allowed up there regardless of feeling like a slowly frying egg.  There was enough of a breeze at first to prevent the sweat from pooling and dripping.  But then we turned around and the breeze died.  Everyone went below except for me a couple of die hards.  I felt bad for the woman sitting next to me when I finally returned to the cabin–I’m pretty sure my deodorant failed.

My photos also failed.  Between the extraordinarily bright sun (one of my friends recently asked if we were still the 3rd rock from the sun–I think she’s onto something) and the moving boat, I can’t say I got any really great shots.  I really wish I had one of the two Osprey chicks both fully visible, but I was shooting between people’s heads to get the shots I did get.  I’m thinking about starting an etiquette blog for photographers where I can offer my advice on tough questions such as “when is it OK to knock over a dozen tourists because they keep passing in front of your lens while a nest of Osprey is in full view?”

I suppose I will have to go on a private cruise if I want really good shots.

Slow the Circles Down

If you have read some of my earliest posts, you may recall that I have issues with going backwards.  I arrange my life around maximum efficiency whenever possible by minimizing repetition, back-tracking, and wasted motion.

There are some consequences associated with this.  For one, I tend to focus on the goal and not on the journey.  The very physical consequence is that I frequently run into things.  I think this may also serve well as a metaphor.

Another consequence is that I often move on completely and usually without regret.  Been there, done that.  I’m over it.  Time for the next adventure.

But every once in a while, something sticks and I don’t mind going back to it over and over.  The Tennessee Aquarium is one of those things.  Every time I go, I discover something new.  Someone is awake who was sleeping last time.  Or the absence of someone else allows me to see others for the first time.  And there are certain exhibits I never tire of.  I have to refrain from block tackling all the small children at the display where you can touch the stingrays–the darn kids are always in my way.

When it comes to shooting at the aquarium, it remains a challenge.  Trying to shoot through glass is always an interesting proposition.  Between the distortions and the bright reflections in the glass, the dim lighting, and the movement of the creatures, it’s a wonder anyone ever gets a shot of anything.

Using a flash helps if you have the right angle.  I admit I love watching people with their little automatic point-and-shoots standing directly in front of the glass and getting frustrated when the image they get is the flash bouncing off the glass.  In my defense, I only get a chuckle out of this because they’re usually doing this right in front of a big sign that says “NO FLASH PHOTOGRAPHY.”  It just seems like karma.

I, however, usually opt for no flash in the aquarium.  This is for several reasons.  First, I’d rather end up with blurry pictures than disturb the animals (anymore than they are already being disturbed).  Second, I still pretty much suck at using a flash.  And finally, I really want to set the flash up off-camera, but that doesn’t work well in a crowded aquarium.  Try to imagine me carrying my umbrella stand around and yelling at small children when they bump into it.  Does not make for a good time.

But, when we took Pat’s family there during their visit, the otters decided to make an appearance.  I find it fascinating when looking at the otter shots that the otter moves faster than the water.  Where the water splashes are frozen, the otter blurs.  None-the-less, I couldn’t help but share my blurry, badly framed shots of the otter doing a back flip.  That was just too adorable.

Maybe next time I’ll catch a stingray jumping out of the tank.

Food and Water

After a few hours of wandering around Chattanooga and the Tennessee Aquarium, it was time to eat.  The six of us headed towards Big River Grille and Brewery.  Although Pat and I have been there a few times, it was the first time for dinner.

The 7-month old entertained us through the whole meal.  She is one of those babies that smiles and laughs and looks amused most of the time.

The 4-year old did some interesting things with his food.  He created a whole new presentation by rolling it into balls.  Since we had just come from the aquarium, perhaps he was thinking about fish bait–he is apparently quite the fisherman.  He already knows far more than I do about fish.

After filling our bellies, we took a brief break so we could play with the dogs and the four-year old could change.  Then, we headed over to Coolidge Park to check out the water fountain.

This is a fun feature in Coolidge Park.  Large animal sculptures surround the fountains, providing nice climbing structures.  I enjoyed shooting the 4 year old at play.

I recently had a conversation with a couple of photographers about using the “aperture priority” setting.  (Aperture priority allows you to set the aperture manually and then the camera automatically adjusts the shutter speed.)

Apparently, this was stressed as the setting to use all the time at a recent workshop.  I’m of the opinion that there is nothing that applies all the time, but aperture priority is nice when you’re shooting a subject that is moving quickly through different lighting situations.  However, I’ve found that shooting a subject where the background changes but the lighting on the subject doesn’t in aperture priority causes the subject to be incorrectly exposed depending on how light the scene is behind the subject.  For this reason, my default mode is manual.  If I change to aperture priority, I make a conscious decision to do so and I know why I’m doing it.

The irony of this is that I either had a mental malfunction that caused me to not check my exposure or my camera malfunctioned when it read the exposure.  Since I’ve not had this problem before or since, I’m guessing it was user error.  I ended up with about 300 shots that were either horribly over exposed or horribly under exposed.

If aperture priority were my default, I might not have gotten the depth of field I wanted, but I would have at least gotten properly exposed images.

The best default would probably be to always check my settings and my exposure before I fire off 300 shots.  🙂

I’m going to write to Canon and suggest an alarm that goes off if you start shooting without changing settings or viewing a shot.  It can be called the “Alzheimer’s Indicator.”  If it goes off more than 50% of the time, it’s time to get an evaluation.  Photography as diagnosis–who says it’s just a hobby?
