Math, Chemistry, Physics and Biology

Math, Chemistry, Physics and Biology. Those were my favourite subjects in school. In the schools I attended in Antigua and St. Vincent these subjects are taught simultaneously from Form 3 to Form 5 ( the equivalent of grades 10 through 12). I loved these four subjects and did very well with them. For me, these four subjects are all a continuum of the same thing. Math helps me solve the physics problems. Physics helps me understand the molecular world of chemistry. Chemistry helps me understand the cellular world of biology. It's all just a way to understand the natural world around me.

The best year of my high school life was when I met a red-headed Canadian boy, Andy Williams, while attending St. Joseph's Academy in St. John's, Antigua. Andy encouraged my love of science and math. Together we used our maths skills to create two unique encoding methods for handwriting. We knew the codes so well, that much to the chagrin of our English teacher, we could read and write in our special language as quickly as we could in English. We couldn't wait for the school day to end so that we could go explore the natural world. Most of our note passing was about solutions to problems we were working on. I still make use of the special symbols – the one I created for my name -- when I want to leave a mark on drinking glasses.

We used our math and physics skills to create and test designs for various paper aeroplanes. We spent countless hours folding paper -- technically we were crafting origami -- and either tossing it into the air or firing it from a rubber band.

My Dad bought me my first aquarium when I was about 12 years old. It was something I wanted very much. I loved observing the natural world and I spent a lot of time learning about fish and ecosystems. Andy and I took it to another level when we decided to crossbreed some of the common varieties. We learned about Gregor Mendel and genetics and heredity. We bought some fish, learned about their reproductive cycle and by the end of a summer had crossbred several varieties of platies1, guppies2, mollies3 and swordtails4.

The USA is too litigious a country so what I'm about to write won't be understood by Americans. Some of you will think this kind of knowledge is dangerous. I did well in chemistry, especially organic chemistry. I learned how to make small explosives. I lived on a volcanic island. Sulfur and carbon and other chemical compounds were not tightly controlled as they are in the USA. We were free to experiment and try different things out. I think at one point I figured out how to make explosives from potatoes and charcoal. I know that this sounds dangerous too many of you reading this. Without being free to experiment, science students will see the subject as boring. This is one reason science continues to decline as an area of study in the USA. Imagine being taught how to play a basketball game but never being allowed out on the court to play?

My love for these sciences led me to electronics and computers. If you talk to my Dad, he will tell you that as a young man, I was constantly taking things apart, sometimes new things. Like my Dad's shortwave radio. I took that apart and used the parts to create a radio transmitter. Station KLW. With no Radio Shack on the island, taking apart electronics was the only way to get parts for my circuits. That meant learning to identify transistors and resistor values by sight.

When I finished high school I went off to college to study physics and computer science. I have degrees in Physics, Electrical Engineering with a minor in Mathematics. If I had taken just a few more courses I would have had a major in Maths. The computer science idea was dropped after I realized it meant sitting in front of a screen for hours at a time. What a fracking mistake that was. I was always better at the code, especially when it was applied to controlling a physical device (like a micro-controller).

From a career standpoint, none of these subjects is relevant to what I do. By the time I had finished my graduate degree in Electrical Engineering, many engineering jobs were being sent overseas. I worked at David Sarnoff Research Center center for two years. Just after I left in 1997, Sarnoff had major layoffs. AT&T Bell Labs disintegrated. Most of the people I have worked with in my 15 years working in IT are former engineers and scientist from Sarnoff and Bell Labs.

None of this matters today. I no longer create codes. I don't have a fish tank. Basic chemistry is illegal in the USA. I only use Maths when doing my taxes.

vividHDR

I love HDR photography. In case you don't know what that is you can head over to Trey Ratcliff's website for an explanation. Here's my quick version. In HDR photography, the photographers take at least two (three or more is better) exposure bracketed and through the magic of software, algorithms combine them into a single image. As you can tell from Trey's photos, the results can produce a striking increase in dynamic range.

I capture most of my images for HDR work on my Nikon. However, setting up a tripod, DSLR and wide-angle lens while stopped at the side of a narrow country road with cars whizzing by is a less than ideal experience. Sometimes my iPhone is the most convenient camera I have with me. I've experimented with various HDR apps for the iPhone over the last few years, but I always found them lacking in some aspect. I've installed and deleted about half a dozen HDR apps from my iPhone. vividHDR is the first HDR app that has a chance of remaining on my iPhone long-term.

vividHDR is a simple app. This simplicity is one of the reasons I like it. Most HDR app overwhelms me with a million pre and post-processing option. Contrast that with vividHR, which launches right into a camera-ready mode.

Tapping the icon on the bottom left of the screen brings up several HDR presets. When I started writing this review, the app only had three, but a recent update raised that number to five. It doesn't matter which one you chose upfront since you can switch between presets after the HDR is created.

Tapping the lightbulb in the lower right corner overlays icons indicating how to use the app.

Swiping to the right reveals a vertical menu. From here you can toggle on/off geotag, overlay grid, auto-preview, select and setup sharing options, and how you want to save the original and HDR images.

Swiping to the right will let you swipe through each image in the photo gallery. You'll get another set of menus on the bottom of the screen. You can compare the original photo to its HDR version or share the HDR image, make editing changes or delete the photo. I've never used the image editor. I usually stick with the results from the presets. If I do want to make an edit I prefer using another app like Photogene4.

Tapping the i in the upper left-hand corner will bring up some meta-information about your HDR image.

I like the fact that vividHDR has its own internal gallery/lightbox and saves images exported to the Photos app to its album. The iOS Photos app can get so cluttered and sometimes I have difficulty finding the photo I want. Whether I am snapping a picture to post to [Pressgram ][http://pressgr.am\]or upload to a blog posing using Poster, being able to navigate to an album with just the images I need makes things simpler.

Although the app is simple to use, taking a good quality HDR image requires some patience. The app has to take three photos and merge them. Neither the camera nor the subject must move or change while the images are being captured. Although the app can be used handheld, I recommend bracing yourself against something -- a tree, a pole -- to reduce movement. For the photo below I leaned against my car to get the shot. Or maybe you can keep a mini tripod and iPhone mount such as the Glif in your glove box.

Google+ PhotoWalkers Are Awesome!

As you know, it takes a Long Time to become friends with someone in the normal way. But, these photowalks are like Speed-Dating-On-Steroids-For-Friends. Everyone that shows up to these events are curious and kind -- exactly the kind of people I like to hang out with. Beyond that, we have other huge overlaps in interests... Sci Fi, Post Processing, Technology, Exploration, Gadgets, Art, etc etc etc -- It's actually quite rare to find people that I enjoy talking to (!!!), so to have hundreds show up that have a heaps of common interests -- well that takes all the sloppy "introductory stages" of becoming friends out of the equation. And then we can move on to just enjoying one another while we walk around and take photos. Trey Ratcliff

I wasn't there but I know the feeling.
