World Water Day, 2010

Posted on 3/22/2010, under ,


If you're anything like me, you've had at least one of your many digital news streams inform you that today is World Water Day (WWD for the rest of this post). In fact, if you're even more like me, you have never heard of this yearly observance, and would usually content yourself with noting the fact in passing, or maybe mentioning it as an offhand comment during an awkward pause in conversation.

Instead, I decided to look into it a bit more, primarily because I wrapped up a water droplet shoot with a friend of mine just yesterday, and thought it would make an intriguing post.

From the World Water Day 2010 website:
 The World Water Day 2010 and its campaign is envisaged to:
  • Raise awareness about sustaining healthy ecosystems and human well-being through addressing the increasing water quality challenges in water management and

  • Raise the profile of water quality by encouraging governments, organizations, communities, and individuals around the world to actively engage in proactively addressing water quality e.g. in pollution prevention, clean up and restoration.
Before I go too far, there are a number of good resources out there on the subject. I'll include those that I have found most helpful in understanding the intent behind the observance:
  • World Water Day 2010: The official site for WWD 2010, and a great place to start. While the events that are listed have finished, it would be worth looking into some of the photos that starting finding their ways back here from those events.
  • World Water Day - Wikipedia: The Wikipedia entry on the event, with info about past years' themes and links to even more useful resources.
  • UN-Water: The official website of UN Water, and "inter-agency mechanism" for collaboration on the subject of water for UN agencies, and the group responsible for WWD.
Before you start worrying about the content of this post, this isn't going to be just another sob story. In fact, quite a bit of progress has been made in the last ten years, such that, according to UN Water, 87% of the world's population has access to sanitary water. One can also be reassured by the progress of technology in the area of water sanitization, as there exist pretty cool and easy to deploy solutions for cleaning water without electricity. Considering the fact that the last I heard on the subject was that the next wars would be fought over water resources, this is good news overall.

Of course, the earlier statistic I mentioned also means that 13% of the world (approx. 884 million people) lack access to clean water, which isn't acceptable. What further complicates matters is that the lack of clean water disproportionately affects those living in rural areas over city dwellers. From the UN Water Joint Monitoring Programme Report:
Despite the world’s population being almost equally divided between urban and rural dwellers, the vast majority without access to water and sanitation live in rural areas. Seven out of ten people without basic sanitation are rural inhabitants and more than eight out of ten people without access to improved drinking-water sources live in rural areas.
Considering all of this info, I began to become more aware of the consequences of my own ease of access to clean water. Despite all of the issues undoubtedly plaguing LA tap water, it is entirely drinkable, and thereby significantly better than anything at least 13% of the human population has access to. I won't even feed my cat this water, and yet almost 900 million humans would have their lives fundamentally improved if they had it available. Clean, safe, fresh water is so readily available to us and so taken for granted that I don't think I could have found non-potable water to use for this shoot if I had even considered the idea.

Unfortunately, there must be significant barriers to transporting this apparently plentiful resource to those who need it, else I can only assume that there wouldn't be people in need of it. In my searching on the subject, the coolest solution to the problem that I could find is a water filtration system known as a Bio-sand Filter (Wikipedia). From the article:

BioSand Water Filters are a technological adaptation of the centuries old slow sand filtration process. While implementations exist in many different sizes and varieties, the most common design is intended for use in rural homes where naturally safe or treated water sources are not available.

BioSand Filters remove 95.0 to 99.0% of organic contaminants, including bacteria, viruses, protozoa, worms, and particles. Safe water produced by the filters is free of discoloration, odor, and unpleasant taste, and can be used for drinking, food preparation, personal hygiene, and sanitation. Most common home-based models can produce between 20 and 60 litres of water per hour.

While it's easy to feel guilty about wasting water for the sake of art, I found myself feeling that I could at least do something to offset my waste, much in the way people offset their carbon footprints. I didn't find any sites specifically for offsetting your water wasting habits, but I did happen upon Charity: Water. With a little browsing, I found my way to their Unshaken program, which specifically provides clean water resources to survivors of the quake in Haiti.

A quick $30 donation there didn't mean much in the greater scheme of my own finances, but it will mean a year's worth of clean water for someone displaced by the quake in Haiti. At the very least, I will feel a bit better the next time I end up using clean water for shots like this:

We (myself, Caroline, and Natalia) took a trip up to Mulholland drive to try and see some of Tuesday morning's Leonids meteor shower. Have to say, I was particularly struck by the idea that the two streams of particles causing this year's shower were from a comet's passing in 1466 and 1533, and so I decided to bring my camera along and see if I could capture anything. So, without building up the suspense any more than is completely necessary, here is my most recent attempt at photographing a medieval event:
(Get it? "Photographing a medieval event"? 'Cause I usually take photos of medieval recreation events, and the comet passed during the... OK, it's lame =P)

It comes across pretty low-res here, so I highly recommend clicking through to the image itself, but that little streak above the horizon and just right of center is the only meteor I captured on film. Now, I don't mean to sound negative about this... I'm extremely happy and feel quite lucky to have captured anything, especially because we only saw about 10 meteors the entire four hours we were up there watching. Furthermore, this was the best one of the night, and I didn't even see it myself until I went through my photos!

When I say that this was the only meteor I captured, I actually mean that I got something other than meteor shots out of this. Yes, I learned more about astrophotography (I hope that's a real word =P) which will inform my future attempts and improve my photography skills. That's cool, but I'm always learning and improving when I go on a shoot. I also took the 400+ exposures that didn't include a streak of burning dust and put them together into two stop motion videos of the night sky changing as the earth rotates.

This first one includes the image above, and shows the hillside along Mulholland as seen facing almost due North-East:

The second is from another angle looking out over the greater Los Angeles area. Didn't capture any meteors as far as I know here... the bright streaks you do see are all planes going to or coming from LAX, spread out over the 15 second exposures:

Again, if it's difficult to see these very well, it might help to click through and view them on the YouTube site.

For reference, these shots were taken on my Sony Alpha 300 using the kit 18-70mm lens at an effective focal length of 27mm, ISO 400, with 15 second exposures at an f-stop of 3.0.

A selection of shots I took at an independent hip hop out in Santa Monica. Enjoyed switching between my flash with a massive light-diffuser to make sure I didn't miss too many good images and making use of the ambient light for more dynamic pics.

On the subject of things I learned at this shoot:
  1. Experiment, play, go with what works, but don't stop experimenting.
  2. Flash-lit scenes can have significant potential too, but natural lighting is always fun.
  3. Flash diffusers are awesome... especially when you make them yourself.
  4. ISO 800 is grainy. Use with extreme caution.

Some pretty nice fish photos here, if I do say myself. Took some time to finally dust off my camera again and enjoy a day out and about rather than inside studying. I've been to the Aquarium of the Pacific before, and I remember being particularly disappointed with the experience. This trip was far from disappointing, and I really appreciated the variety of sea life as well as the obvious effort that went into curating the individual exhibits.

I was especially glad to have my circular polarizer on hand for this trip. On top of filtering out the glare from the top of the water on my sting ray shots, it proved handy in reducing some of the reflection when I found myself shooting through glass. I actually had to throw out a few ray shots because the water just looked too clear and the resulting diffraction was distracting. There were times when I just didn't have the extra light to spare while shooting indoors and through glass, and my solution was to be particularly aware of any reflections and try to reposition myself to avoid them as much as possible. One helpful hint: I wore a white shirt to the aquarium... When shooting in situations where glare could be an issue, wear a black shirt to prevent a little more reflection.

I might have tried to use a flash to improve these shots by pulling off a little catch light in some of my subjects' eyes, but I was a bit annoyed with all the people who were blinding everyone else with their point-and-shoot camera flashes. A quick cost-benefit analysis led me to decide it wasn't worth being the source of further frustration. It was poetic justice to listen to one tourist complain about her camera being broken because she kept getting a big white spot in her pictures.

Finally, this was my first shoot using my Lowepro Slingshot 100AW as my new camera bag. I didn't have to do any quick lens changes or stash my camera away for too long, but it holds all of my traveling gear comfortably and safely, and sits surprisingly nicely for a sling bag. I don't really have enough experience with it to justify recommending it, but this was a good first experience.

Griffith Observatory

Posted on 7/14/2009, under ,


It's been a while since I took the time to update, so I thought I'd finally upload this photo set. A small set of pics taken at and around Griffith Observatory in Griffith Park. These come from two trips with two separate cameras, my old Minolta Maxxum 5 (film) and my new Sony a300 (digital). You can probably tell the difference pretty easily both in the quality of the digital images and in the changes to (and I hope growth in) my style and technique.

A set of photos I took for Analog Dive at The Terrace in Pasadena on May 4th, 2009.

This was before I picked up my dedicated flash unit, and I tried a few shots with the on-camera flash, but they were just as flat, blue, and boring as you'd expect. I bumped my ISO to 800 (despite the noticeable increase in grain), got creative with the exposures, and trusted my steady hand and built in image stabilization (thank you, Sony/Minolta) to make up the difference. Balancing my shutter speed ended being the trickiest part, as I wanted to capture the motion and flow of the artists without blurring them beyond recognizability. It was a bit risky, to be sure, but I ended up getting some pretty solid results with minimal processing.

I'm learning to trust a flash more now that I have my Sigma EF 500DG Super, but this shoot really reaffirmed my belief in the benefits of being able to work with the light you've got. Sure, If I had access to some lower f-stop lenses, I could've dropped my ISO back to a more reasonable number and had more room to play with my exposure. I could've shot with my on-camera flash all night and post-processed the heck out of my images to wrestle the quality back into them. I have a solidly professional flash unit now, and will make use of it as necessary. Whenever possible, though, I'm going to keep my flash tucked away in the bag, and let the scene light itself.

Disney's Electrical Parade

Posted on 6/23/2009, under ,


Photos from Disney's California Adventure's Electrical Parade. It was fun having the remnants of memories light up in response to many of the floats. There were a number of challenges for my gear on this shoot, and I think I spot some lens aberrations, but I'm overall quite happy with this selection of shots.

Some photos from the Hound Coursing at Potrero War 2009. This is in part just a test of this blog and integrating it with Flickr, but I wanted to use these photos in particular in order to finally be able to share them with the dog owners and those who ran the event.
