Brain Science Demonstration From the Photography Blog THEME

http://www.the.me/the-human-brain-sort-of-a-virtual-darkroom/

I work in brain science. I love it when I find overlaps between my chosen career and my chosen hobby. This one is great.

Here's the experiment that you should perform: Make the image above as large as possible on whatever device you're reading from (an iPad worked well for me). Stare at the red dot on the model's nose for 30 seconds. Now, look at a blank light surface (like a white wall) and blink several times. You'll see the negative image above turn into a positive image. Amazing.

(Click Here) to read the original post on THEME.

So, what's going on here? It's called a negative afterimage. Basically, what happens is that by staring at the negative image long enough, you are saturating some of the photoreceptors (cone receptors, to be exact, those that detect color), but not others. The receptors specifically tuned to the colors in the negative image become saturated, and when that happens, they become less sensitive. Receptors for colors not in the image are not affected. So, when you look at a blank surface, the saturated receptors give you a sense of very low levels of the color you saw in the negative, while colors that are absent appear relatively stronger, giving you the sense of an image with colors opposite to what you looked at.

Pretty cool, huh?

Combining Two Loves - Science and Photography

I have just achieved a milestone. Combining my love for field science and photography, I have the incredible honor of being published in a first-rate Paleontology journal with a true leader in the field, Dr. Robert Weems. Our paper on amphibians and non-marine turtles from the miocene period was published in the July issue of the Journal of Paleontology.
 
(Click Here) to read the abstract.
 
My minor contributions to the work included two things - finding a humerus bone from a several million year old land turtle, and taking all of the photographs for the paper. Dr. Weems provided all of the scientific expertise, writing, and editing.
 
Here's the sample that I found:

Leica at The White House!

I recently nominated my friend and colleague, Jason Osborne, for a White House science award known as Champions of Change: Citizen Science. Guess what? He won! And, I got an invitation to accompany him to The White House in Washington, DC to receive his award.

Okay. The event was at The White House, not in The White House. It was actually held inside the Eisenhower Executive Office Building (EEOB), adjacent to The White House. A massive, imposing structure, EEOB is full of history and executive presence.

The event was moderated by Joe Palca, Science Desk Correspondent for National Public Radio (NPR). Philip Rubin, Principal Assistant Director for Science, White House Office of Science and Technology Policy and Ellen McCallie, Program Director for informal Science Education, National Science Foundation (NSF) gave brief talks about the importance and wonder of "Citizen Science," which is a new breed of science, where citizens (both ordinary and extraordinary, but not necessarily career scientists) contribute to scientific discovery and advancement, and gain science education through participating in real science projects.
 
Jason won the award because of the citizen science program that he and partner-in-crime Aaron Alford (co-founders of a non-profit called Paleo Quest) developed to involve the public in discovery and description of micro fossils. The program is called SharkFinder. (Click Here) to read about Paleo Quest and SharkFinder.

This was an incredible opportunity for me. I thoroughly enjoyed the event, and consider it a once-in-a-lifetime chance to photograph at The White House. I'm also extremely proud of Jason, Aaron, and Paleo Quest for their success - all the result of hard work and concentration on the importance of science and education.
 
For more information on the Champions of Change program, (Click Here).
 
I decided to shoot my Leica M9 at this event, knowing that I'd want a fast lens, quiet operation, and likely no flash. I settled on the Summilux 35 because of the fast f1.4 aperture, and the 90mm Elmarit f2.8 for longer shots. I did not want to be fiddling with lens changes during the event, so I kept it to these two lenses. I'll admit that I was tempted to shoot a Nikon DSLR and zoom, which would have worked fine as well. As it was, I felt that my work was unobtrusive, and I'm pleased with the results overall.

Scientists Make Insect-Like Compound Eye Sensor

 
This post comes close to bridging my hobby (photography, obviously) and my real occupation (science).
 
A project at the University of Illinois Urbana-Champaign has produced the first electronic sensor that uses the concept of compound eyes, as demonstrated in nature by many insect eyes. Compound eyes are made up of independent imaging sensors, known as ommatidia. Each ommatidium has its own lens, independent of all the others, and its own sensor.
 
(Click Here) to read a review of the project on the BBC news blog.
 
This design from nature has the benefit of being able to cover a very wide angle without extreme distortion as seen with a single wide angle lens, and it can simultaneously focus at multiple distances.
 
While the immediate applications being considered for the compound sensor include miniature flying robots and such, it does make me wonder how it could be applied to art. Very interesting.

Cabin fever has finally reached its end. Today (Saturday, April 27, 2013), I had the pleasure of taking my daughter and two of her friends out fossil hunting with PaleoQuest founders Jason Osborne and Aaron Alford, and Science writer Kerry Klein. It was a perfect day to be out at Calvert Cliffs, on the Chesapeake Bay.
 
PaleoQuest is a non-profit organization, focused on bringing science, particularly Paleontology, into the hands of students.
 
(Click Here) to check out PaleoQuest's very active approach to improving science education.
 
I shot this fun little video (click on it) of the kids showing what it's like to find a fossil shark tooth. Really, it just gave them a chance to goof off:

Here's an example of one of the fossil shark teeth found on this beach, from the largest shark that ever lived, Carcharocles megalodon:

This was a great day. I find it increasingly difficult to find an activity that pleases three twelve year olds; this one did the trick. It was a blast to get out and combine family, friends, science, and photography into a single day!

On Crows and Urban Naturalists

 
 
This is the absolute perfect image for me today. I found it on Diane Varner's Daily Walk blog. There's a little prose to go along with it.
 
(Click Here) to see the post on Diane's blog.
 
 
Why does this fit my thoughts today? Well, I just finished reading a great book about urban naturalists and crows last night. It's called Crow Planet, by Lyanda Lynn Haupt (see the link below). This is a great book. It centers discussion around crows and how they thrive in urban environments, but is really about how to be a naturalist without living the true wilderness. Haupt does a good job of helping us to be realists about the "highly disturbed" nature of our greenspaces and yards, yet study nature for what it is today. She carries binoculars and a magnifier with her every day in her life in Seattle, Washington. She welcomes spiders into her home. My kind of gal.
 
So, you can see why I was drawn to Diane Varner's picture above, I think.

Fossil Hunting in Maryland with the Lumix DMC-TS3

Erosion Forces, by Reed A. George
Panasonic Lumix DMC-TS3
 
Last Sunday morning, I got up early and headed to a place on the Potomac River known as Liverpool Point, to do some fossil hunting. The video above shows the important parts of the scene - cliffs to the right, literally full of fossil material, the waves coming in from the left, day by day eroding into them. In the middle, beach, and awesome opportunities to find fossils that have washed out of the cliffs.
 
I packed up a Lumix DMC-G3, 14-140mm and 100-300mm zooms, and carried them in a waterproof bag on my back. I never took them out. The TS3 covered everything I needed to shoot. In fact, the TS3 did far better in closeups than I could have done with the G3 and the zooms I had. Of course, if I'd brought along the Macro-Elmarit 45mm f2.8, that would have been a different story. As it was, I just used the TS3, and never worried about getting it wet, etc.
 
Here's a cross-section of the cliff, showing just how dense the fossils are in places.

This area is known for fossilized sand tiger shark teeth. Here's one sticking out of the cliff matrix.

I also found a fossilized crocodile tooth - much less common. It's amazing to think that enormous crocodiles and sand tiger sharks once prowled the waters that are now the Potomac River. These ones were from the late Paleocene, approximately 55 million years ago.

It is great to be able to get out and hike the shore at sunrise, collect fossils from animals that lived there 55 million years ago, and be home in time for lunch (or nearly so).

Panasonic Lumix DMC-TS3 Goes Fossil Hunting

Fossil Skull? by Reed A. George

I took my little DMC-TS3 to the beach yesterday, where it belongs. The waterproof feature makes it perfect for trips like this. We went looking for fossils, and found a lot. The one above is by far the most intriguing. I'm still conferring with the experts (not me) to decide what it might be, but I'm pretty convinced it's a skull of some type.
 
These deposits are from the Pliocene, about 2-5 million years old.
 
In addition to the big find, there were lots of great shell fossils to peruse.

I am very pleased with the Lumix DMC-TS3. For all of these shots, I used the Intelligent Auto (iAuto) setting. They are all directly out of the camera, with no editing whatsoever. It couldn't be easier to get decent shots in good light. And, the GPS is also very useful.

Panasonic Lumix and National Geographic Collaboration Report - Counting Species in India

As I've reported in the past, Panasonic and National Geographic have formed a collaboration, which is super exciting to me. They have just issued a brief report about working with a researcher who studies biodiversity in India's Pakke Tiger Reserve.
 

Image Source: http://panasonic.net/avc/lumix/nationalgeographic/earthswitnesses/india/report.html
Hornbills Are One of the Most Important Seed Dispersers in the Indian Rainforest
 
(Click Here) to see the first episode, which includes a link to a four page pdf document.


The Lumix team worked with Dr. Aparajita Datta, who has spent over a decade studying and working to conserve the tropical forests in Northeastern India. Her research focuses on the "phenology" of the forest, which is the flowering and fruit bearing behavior of trees, to understand the baseline patterns of the forest, and detect any changes. The phenology includes study of trees whose seeds are spread by mammals, birds, and wind. Following is a quote from the report:"“Understanding connections and interaction between animals and plants is the part of my work I find most exciting,” Dr. Datta says. The area is home to five different species of hornbills, and Dr. Datta studies their role as seed dispersers. In tropical forests, 80 percent to 90 percent of tree species bear fruits that animals disperse so these birds are critical to the ecosystem. In addition to her scientific work, Dr. Datta has a passion for educating the next generation of engaged citizens. She has co-written two books for children on hornbills and rain forests and produced other educational material to foster a greater awareness and appreciation of Indian wildlife among urban and rural children." In addition to a short video with Dr. Datta, and eleven still photos, the site includes a second gallery of images from India.


I very much look forward to the coming episodes two and three, which promise to include many more exciting images from the collaboration.
 
Working in Science and being an avid photographer (and Lumix fan), I can't imagine a better match-up of my interests.

Lumix Blog Returns - First Quarter of 2012 is Over; Do You Know Where Your Goals Are?

 
Jumbled Goals?
Are Your Goals for 2012 Still Coherent?, by Reed A. George
Panasonic Lumix DMC-G3, Lumix 14mm f2.5
iso160, f5, 1/1600 sec

Well, I have been thinking that the first quarter of the year 2012 is now gone, and so far, I have done a good job at keeping up with my goal of having an active blog that keeps me focused, and also hopefully interests a few people. Based on the page view statistics, I would say I have achieved the second goal. I know I've achieved the first.

I read an article on the B&H blog about setting, working toward, and achieving your photographic goals.

(Click Here) for the B&H blog post.

In the B&H post, three professional photographers talk about photographic goals.

First, Peter Hurley suggests setting three levels of goals: 1) the Major goal, which is not easily achievable; heck, you may not even know how to get there, 2) the Minor goal, one that is achievable, but significantly builds toward the Major, and 3) Incremental goals, which are what you knock off each day in pursuit of your bigger goals.

Next, Zack Arias, Fashion Photographer, talks about how his personal projects are typically related to his work, but with enough of a change to make them fun again. Zack is working to make his projects more personal. He also has a policy of not looking at other photographer's work. I find this one interesting. I gain a lot by looking at the work of others. Perhaps I'm just not confident enough about my own creativity? I understand that we should not copy others. However, I think not look at the work of others would deprive me of a lot of my photographic enjoyment. Finally, Zack needs others to keep him on task with the small stuff - social marketing, email, etc.

Ryan Brenizer, Wedding Photographer, suggests that your annual goal should be to beat last year's "you." I like this one. As long as we're better than we were last year, things are going in the right direction. He also preaches endurance, saying that you need to do that 250th wedding to really have it down. I can appreciate that as well.

Not trying to beat my own drum, but I'm pretty happy with my photographic year of 2012 so far. My two main projects at this point are the 150th anniversary of the US Civil War, and local music from my area, mainly bluegrass. I have shot quite a bit of both, and feel that my work with music and musicians is going along nicely. The Civil War project has been slower. I have been out to the battlefields several times, and to a few events, but now that spring is here, those events will really start to happen with a much higher frequency. There is a third project that I am pursuing - scientific photography - in collaboration with some wonderful paleontologist friends, and some potentially very exciting organizations. I put in some time photographing the fossil collection of the Calvert Marine Museum in Solomons, Maryland, and need to keep at that (we're only ~10% done). And, again, now that the weather is getting warmer, I plan to do a lot more shooting in the field. In addition to my projects, I have been successful at focusing largely (not exclusively) on Lumix cameras and equipment, and have been very diligent in keeping this blog going and lively. Finally, I have hung images in one show (sold one!), have another show scheduled, and plan to do more this year, and have one first place in two categories of a local photography contest (more to come on that when it's announced).

Of course, I'd love to be out shooting more. But, until blogging and shooting the things I love see serious increases in demand and pay (please use those Amazon links on my page more!), I will have another more-than-full-time career (which I also love, by the way). So, all in all, 2012 is going well.

I do find that just being out there shooting, or in here writing, the more I do, the more opportunities I have.

I hope you are enjoying my "work" here as much as I am.

So, in my full-time job, I work for a biomedical research organization. One of our researchers studies the predator-prey behavior of dragonflies. It turns out, these guys are the ultimate predators of the insect world, and exhibit very complicated visual processing and use sophisticated guidance algorithms to intercept their flying prey in mid air.
 
Okay, by now you're wondering "What the heck does this have to do with photography?" Well, our scientists gather dragonfly larvae, like the one above, from the ponds on our campus. I got the opportunity to enjoy a little warm spring weather, and photograph them in action.

While they were collecting, we started to notice what we thought were frogs singing to each other. They turned out to be toads, Eastern American Toads (Anaxyrus americanus americanus), which were quite amorous, and the singing led to other things.

Lunar New Year and the Color Red

Here in Washington, DC, this coming weekend will mark the celebration of the Chinese (Lunar) New Year.  It is the year of the dragon, most auspicious of them all.  DC will host a Japanese New Year celebration, as well as the annual Chinese New Year Parade in Chinatown.  Here is an image I took at last year's parade:

A Couple of Examples From the Fossil Shoot

In my earlier post today, I showed the setup I used to start photographing the fossil samples at the Calvert Marine Museum.  I thought it may be useful to show a couple of examples of the images taken.

Keep in mind, these are for scientific and not artistic purposes.  They were shot in the smallest file size available on the Nikon D700 (2,128 X 1,416 pixels) in order to save time and storage space.  I did my best to optimize the lighting to show the features of the specimens, using cross-lighting with two flashes.
