“It suddenly struck me that that tiny pea, pretty and blue, was the Earth. I put up my thumb and shut one eye, and my thumb blotted out the planet Earth. I didn't feel like a giant. I felt very, very small.” – Neil Armstrong (1930-2012)

Imaging Expo 2007

Yesterday I went to check out the Imaging Expo Singapore 2007 exhibition, held at Suntec City.

I'm sort of a photography enthusiast.

Real photo enthusiasts carry digital SLR cameras with bazooka lenses.

I do have an old manual 35mm SLR with all the works (now a farm for growing fungi) but my current walkabout is an ordinary 傻瓜机 (idiotproof box) with a temperamental autofocus and a useless flash.

It's far from perfect, but oh well, it takes photos.

That suddenly reminds me of a great line from a lady stand-up comedian!

She asked a member of the audience: "What car do you drive sir?"

He said, "I drive a '04 Ford Mustang 2-door coupe with V6 engine and 5-speed manual transmission."

She then said, "Ask me what car I drive."

"What car do you drive?"

"I drive a white car."

I use a silver camera.












First up - registration. This feels rather formal because they need to print a name tag for you on the spot.

After receiving my name tag I mindlessly asked the counter staff: "Can I take photographs in the exhibition?"

She replied,"Well, I should suppose so since this is a photography exhibition."

Ask a stupid question...













And here is the entrance! Where are the thronging crowds?













The interior of the exhibition hall is only about half-filled. The Canon booth is the most prominent. Most of the exhibitors are companies selling photo printing machines and studio lighting equipment. There is also a number of photographic clubs present.

Compared to popular sales exhibitions like COMEX or SITEX, the hall is almost deserted, but this exhibition targets a slightly more professional demographic.















Two areas are designated for showcasing prize winning photographs: one of them presenting prize winning works from the Photographic Society of Singapore. When I look at the prints on display, I notice that some photos are obviously digital composites. Many of them have colours that are heavily overprocessed to look bright and vibrant.

In this era of photoshop, I guess it's fashionable to modify your original shots by that much.

As I walked around this area, I noticed that only a few people were looking at photographs.

Where are the others?















Checking out the bazookas, why of course. Canon set up this high platform to show off its range of super long lenses.

I tried out the huge Canon 600mm f/4, coupled to an EOS-1D Mark III body. The magnification is quite impressive, but the viewfinder looks dim and the autofocus isn't as snappy as one of their shorter white lenses.

When I examine the Mark III more closely, I concede that this is the sort of equipment that only professionals can handle, since only real men can haul this brick around all day and not injure their wrist.

I wouldn't (and couldn't) buy one of these as a walkabout camera, without heading to the gym first.

Want to see another bazooka?















Check this out. The gargantuan Sigma 200-500mm f/2.8 zoom lens actually resembles a bazooka.

Just looking at it gives me a backache.

Suddenly there was a flurry of activity at the Canon pavilion. Hordes of photographers were rushing there.

Is someone giving away free memory cards?















The Canon babes are here, HOORAY!

Everyone is jostling to get a clear shot at these extremely thin ladies. Regular Fresh Brainz readers know that I'm no fan of skinny women, but the one in the middle does look quite cute.

It must feel like a superstar to be the centre of attention for so many photographers, with their flash units blazing like crazy, snapping hundreds of photos macam no tomorrow.



















Then the commotion shifted to the Bowens booth because, you've guessed it - the Bowens babe arrived.

You can see a fan machine blowing into the model's face, making her hair flutter slightly. She reminds of Claire Danes for some reason.

A veteran professional photographer was demonstrating how to use studio lighting, turned on one at a time, to achieve good portrait results. He explained that the control of light is very important, and that stray ambient light must be minimized. He also recommended that beginners invest in an umbrella light first, before trying to use box lights.

The crowd was nodding away, pretending to listen.

It's hard to pay attention when a hot babe is standing right there.



















I love redheads.

Here's a shot of the model having an expressionless "passport photo" look. If you see her on the streets, that's how she would look like. Pretty women tend to have an "averaged" face and she is no exception.

However, once she's in front of the camera, she starts working it...



















HOT.















The photographer was communicating by hand signals to tell her how to tilt her face and where to look. She responds quickly and accurately - definitely a professional model.

The photos he took were immediately displayed on the computer monitors at the booth. I noticed that the results he obtained had higher contrast than my photos. Since the studio lighting was so subtle, I don't really understand how he managed to eliminate the stray light pouring down from the exhibition hall ceiling.

And his photos were tack sharp, of course. My compact camera was hunting around in the low light conditions, trying (and often failing) to get a good focus. My apologies for the lack of sharpness.



















HOT.

Did I mention that she was posing with a motorcycle?

I didn't notice it at all when I was there.



















Then it was time to turn the fan on full-blast. Check out how beautifully her hair flies! This almost looks like one of those covers on a fashion magazine.

Maybe you don't need expensive optics when you have a hot babe.














After a lengthy explanation of the lighting system, the photographer decided it was time to let the people in the crowd to take their own photos of the model. The crowd immediately came alive and started to surge forward, aiming their big bazookas at her.

What a flurry of activity!


















I doubt many people were really listening to the demonstrator's talk, because they were firing their powerful flashes at her non-stop. Here's one of my photos that coincidentally caught the flash of somebody else's camera - it was so bright and so direct that it flattened out her facial features, defeating the whole purpose of having all those studio lights.


















Compare the previous photo with this one - with warm studio lighting from overhead, from her front and her right. I find this result more pleasing.

And yes, she is HOT.

Please marry me.














Later in the afternoon, the Profoto booth also demonstrated their lighting equipment with a live photo session. Here the photographer is using a large ring flash to accentuate the glow of the model's features and to produce a subtle shadow around her.

From this angle it looks as if he is trying to nuke her with a microwave radar dish!



















And finally - here is the Profoto babe. She looks great on photos but seems rather snotty in person.

Overall, it was an interesting learning experience, but despite the eye candy I get a nagging feeling that I'm not cut out to be a professional photographer.

"Your destiny lies on a different path than mine."

Indeed, Ben.

I prefer my destiny to lean against a motorcycle with hair flying in the wind.

Heh.

Three-Layered Science Communication

I just finished grading over 680 undergraduate lab assignments (whew!) and while most students know generally what was going on during the training lab, the style of their writing isn't easy to read.

Mangled sentence structure is rather common, and there is quite a bit of repetition and beating around the bush, which I guess is to be expected in this sort of assignment.

Only a handful of students wrote clearly and succinctly, quickly showing me that they really understood the experiment. A few of them even drew illustrative analogies to help explain the experiment in a more visual way.

It's impossible to conclude anything from an undergrad assignment, but I get a sense that there won't be many people who know what is going on in a technical field and can communicate it clearly to lay people.

Science communication is an integral aspect of the science endeavour in developed nations because many of them have such a long scientific tradition that it has become part of their culture. In Singapore however, the scientific endeavour is very young, and the feedback that I get from talking to some members of the public isn't encouraging.

They don't know what is going on, nor do they care. That's sad because some of this knowledge will have direct impact on their lives. They are missing out on some really cool stories about how the Universe works, or how the world of science works.

Even from a super pragmatic point of view, scientific insight can help give them a leg up against their competitors.

So, how to bring science from laboratories and conference rooms into kopi-tiams (coffeeshops)?



















Fresh Brainz will use the animated movie Ice Age (2002) to illustrate our three-layered approach in science communication to capture the public's attention and still provide accurate specialist insights with minimal exaggeration and hype.

Don't worry if you haven't seen the movie - there won't be any spoilers below.

(But you should watch it because Disney sucks and Dreamworks rulez.)

1. Lowest common denominator

The Ice Age movie is meant for both kids and adults.

Kids love it because there is a lot of slapstick comedy between Manny the Mammoth, Sid the Sloth and Diego the Sabretooth tiger.

Not to forget the random antics of the cute and blindingly stupid Scrat!















Even if they are too young to understand the story, wacky physical humour captures their attention and provides enjoyment.

This lowest common denominator transcends age and cultural barriers - the main reason why Rowan Atkinson's retarded Mr. Bean series is far more popular worldwide than his brilliant Blackadder series.

For maximum accessibility, Fresh Brainz is written in plain, grade school English with minimal technical jargon. Slapstick humour and stupid jokes are part of the writing style.

Our lowest common denominator also includes: sex and schadenfreude.

Wait... I can turn this into a slogan.

Science - because that's what I like to write!

Sex - because that's what you like to read!

... and Schadenfreude - because that's the most genuine kind of joy (since it doesn't include even a drop of envy)!

A staple of gossipy Chinese evening newspapers and tabloids, sex and schadenfreude have been capturing the attention of the masses since time immemorial.

Here at Fresh Brainz, we are loathe to tinker with this proven relic of negative selection pressures.

2. Coherent narrative

The basic story of Ice Age is simple - a ragtag group of animals migrating south for the winter, chance upon a human baby.

They don't like each other and may in fact be dangerous to each other. Despite the initial distrust, they slowly become friends and set off to return the baby to the human tribe.

Scientific discoveries and technological innovations don't always lend themselves to good storytelling. Some scientific issues are multi-faceted, theories are not mutually exclusive and experimental data can swing either way. The emergence of new technologies are similarly mired in complexity.

However, no matter how complicated the issue is, to avoid throwing gobs of facts and figures that sound meaningless to the regular reader (or even experts in other fields), a coherent narrative structure is a must.

Prudent simplification is the key.

The story should not attempt to present all the confusing aspects of a scientific topic - just one or two main ideas with clearly explained background, developing gradually using relevant facts and illustrations with intensifying rhythmic intensity until finally... a climax is reached.

Any complications should be then be noted and references provided for people who wish to go into more details.

Complications tend to appear after the climax. It's just in the natural order of things.

3. Insider jokes

Despite the deceptively simple main story of Ice Age, the entire movie is peppered with naughty language and insider references that only an adult (and a well-read one at that) can appreciate.

Not limited to jokes, there is a particularly emotional scene in the film when Manny relives a moment of tragedy and inner conflict.

Kids won't understand it, but adults will cry buckets.

These references don't appear often and even if you don't understand them, it won't affect the story.

Nonetheless, it's a *wink* to those in the know.

In the case of science communication, insider references are essential.

Experts quickly see pass the two layers of attention-grabbing shtick and simplistic storyline to find the details that they want - the significance and novelty of the scientific finding, as well as links to the original study.

In addition they are also soundly entertained by exclusive jokes that make them laugh like the squeal of a CO2 incubator on a weekend.

Insider reference is the highest (or narrowest?) layer of science communication that should be used sparingly, since it's really disturbing to see people winking at each other all the time.

----------

So there you have it, Fresh Brainz's very own three-layered style of science communication, freshly baked to perfection with a mountain of whipped cream and a perky strawberry on top.

Will people eat it up? Or will they lick the cream off and leave the cake untouched?

Ok I'll leave you to enjoy that mental picture.

Mmm strawberry...
