Reticular activation

Recently, I listened to Tim Ferriss’ interview with Scott Adams, who is famous for creation of the Dilbert cartoon. He spoke, with great humour, about the power of positive affirmations (e.g. writing “I will become a famous cartoonist” 15 times a day, every day). Interestingly, the appeal of this technique has something to do with reticular activation system in the brain, which controls transitions between sleeping and awake states, and also between periods of low and high attention.

Hypothetically, we might have filtering mechanisms in our brains that only let relevant information through, while classifying most of the information that comes our way as noise. Examples of this effect include noticing many cars similar to yours after you’ve just bought a new car, recognizing your name spoken in a noisy crowd, etc.

Similarly, we have a tendency to respond to emotionally-charged words, compared to emotionally-neutral ones of similar meaning (e.g. “to yank” is inherently funnier to post people than “to pull”). This gives the writers a particular technique, where they can purposely choose to replace a logically-correct words in their manuscripts with words that have similar (but necessarily identical) meaning, but which have a better potential to engage readers on the emotional level.

Perhaps, photographers can also be conscious about choosing post-processing techniques, for example, that would appeal to the viewers’ emotions (e.g. enhance grain, etc.) even at the expense of decreasing the “quality” of an image in terms of sharpness, exposure, etc.

On relaxation and tension

In kendo, when we initiate an attack and approach the opponent during seme-ai, we are advised by wise senseis to not only maintain a relaxed grip on the shine, but to relax it even more as we apply pressure (metaphorically, speaking, of course, not really in terms of force per unit area) on the opponent. This is done to preemptively compensate for our natural tendency to tighten up at the beginning of the actual physical attack.

Tightening up is a natural reaction of the human body to physical stress. In fact, by consciously flexing our gip on a dumbbell, for example, we are able to pull off a couple of additional biceps curls beyond what would other wise be our maximum number of reps. This very effective principle, among others, is taught by Pavel Tsatsulin, who use to train special forces operators in various countries. According to him, strength requires tension, while flexibility requires relaxation. Ability to switch from one to another quickly and at will is the key to high physical performance.

I was going to make an analogy between this preemptive relaxation that is used to prepare a martial artist for the moment of tension and a creative process like painting or photography, but the specifics of this would-be analogy seem to be a bit far-fetched now as I think about it. If I always take too many shots during a typical basketball game, which makes the culling process long and tedious, should I preemptively compensate my trying to take photos only when the action comes closer, for example?.. As Richard Feynman said about analogies, it is possible to draw one between any two subjects, and therefore, the analogies are largely meaningless.

On strategy

Just as most people think that they are better-than-average drivers, majority of us think that we are better at strategy (e.g. business, sports, politics, etc.) than most of the others. Obviously, this cannot be true. Besides, there is one interesting limitation of being an expert strategist in a particular activity (e.g. basketball), which prevents this expertise from easily transferring to generalized strategy. Specific activities, particularly sports, have a defined set of rules. Learning and practicing to operate and within these rules makes one an expert, but not necessarily a strategist. True strategy implies ability (indeed, a skill) to quickly adapt to the new reality if some of the rules suddenly change or the new ones are added to the original ones.

This is another argument to striving to continuously reinvent oneself in any creative activity. Doing so allows us to practice strategy in the general sense – developing a skill of quickly formulating a model of the operating conditions (the ever-changing reality) from limited observations of those around us. In martial arts, this happens in a very explicit and direct way – by practicing your skill agains different opponents of various ages, body types, experience, skill and ability levels. In other areas, the analogy is more subtle, but it is there. As Richard Feynman put it in his famous interview “The pleasure of finding things out”, the scientific discovery (which is another example of a creative activity) is similar to watching a chess game and trying to figure out the rules. The trick is that we are allowed to see only a part of the board and only from time to time.

Start of the season

The start of our university’s sports season, and my first photoshoot of the season, happened under ideal conditions, photographically speaking. The women’s soccer game that I was shooting took place in the late afternoon, so the lighting was ideal – bright enough to keep the ISO low and diffuser enough to make the shadows soft. I had sufficient time to shoot and process the photos without any rush, because the academic year, with its own obligations has not started yet.

To add to the nice experience, my family was there to watch the game while I was shooting. Everybody enjoyed the event, even though our team lost.

Deconstructing the process: analytical approach to photography

A very practical, strategy-based way of looking at processes or problems is to start with the desired outcome and identifying the key conditions that need to be satisfied to make it happen. Reid Hoffman, the co-founder of LinkedIn, refers to these conditions as “moving variables”. The actual problem-solving then reduces to propagating these moving variables to the present moment, to the level of the next action (in GTD terms).

It is easy to see how this deconstruction of the problem can be applied in academic research, and particularly in the business-like aspects aspects of it, such as grant applications, for example. In martial arts, the connection is even more obvious. After all, the business strategy principles often originated in martial arts, Sun Tzu’s “Art of War” being the stereotypical example of a strategy guide for a modern person.

I think that in photography, this approach could also be very useful, and not only in the business aspects, but in the creative process itself, where approaching it from the starting point of the desired outcome can streamline the workflow and add efficiency by eliminating irrelevant factors and variables. Perhaps, applying this kind of analytical edge could be one way of differentiating ourselves in the sea of aspiring professional and insanely-serious amateur photographers (to borrow a term from Dan Heller).

Painting

Painting can be a very effective excersize for facilitating creative decision-making. Robert Rodriguez, a movie director and an accomplished artist, mentioned in a recent interview that he used to make actors paint on the movie set between their filming sessions. The idea is that making creative decisions related to colour choice, composition, etc. are fundamentally more challenging than trivial details that people are often obsessed about in their everyday situations (e.g. props or makeup/wardrobe/lighting issues on a movie set, for which there are often very efficient workarounds that are not even worth fussing about.)

Followed this example, I decided to paint for an hour or so alongside my four-year-old daughter, using a photo of flowers in the courtyard of the Sforza Castle in Milan that I took earlier this year. It was certainly fun to paint together with my daughter, and I am amazed at how quickly she is growing up and delighted to be able to share this time with her. In this sense at least, painting definitely puts things in the right perspective for me.

On creativity

Recently, I listened to a very inspiring interview with a film director (as well as a writer, producer, editor, composer, etc.) Robert Rodriguez, who shared some neat ideas about creativity, which, according to him, can be found in every human activity. More precisely, we can bring creativity into everything that we do.

This is a neat way of looking at the dilemma of striving to be a polymath versus being a narrow specialist. Rodriguez says that when people ask him why he does so many different things, he replies that he does only one thing – leaving a creative life.

In practical terms, he suggests doing things in short bursts, over periods of half-an-hour of so at a time. In my experience, this approach generally works, although there are some activities (e.g. academic research) that requires larger chunks of uninterrupted time. In fact, working in brief, regular sessions, so called BRSs, can be shown to be the best approach to academic work too. As Rodrigues puts it, you just need to chip away at various personal projects, whether it is learning to play a guitar or painting between filming scenes of a movie, on the daily basis, and by the end of the week, if look back, you’ll see that you are leaving your dream.

A key moment here is not to be afraid to try new things. This requires one to believe in oneself, in the sense that mastery of almost any kind of skill or activity at a very high (indeed, world-class) level is possible, given sufficient time and effort. Rodrigues gives an example (which might not be true, BTW – I don’t think there was a formal study on this) that when very young children are asked, who among them thinks that he/she could be an astronaut, a composer, etc., there is a forest of raised hands, probably due to the lack of life experience on part of the kids. When the same question is asked of the same kids a couple of years later, much fewer hands are raised – there is no significant increase in expense, but somehow the children lose their belief in themselves. As adults, we have an advantage of being aware of what is happening with us, so we should consciously keep raising our hand.

Action shots with an iPhone

Taking action shots is challenging with any camera, because there are several elements of the shot that have to be done correctly at the same time: focus, exposure and composition/framing. Fast moving subjects present challenges in all three aspects, and they are particularly difficult to manage with a phone camera.

I really like my iPhone 6+ camera. It certainly cannot do everything that my 1D X with a fast lens can do, but when the conditions (mostly, lighting) are right, it really shines. You just need to pick your battles wisely if the iPhone camera is your weapon…

Today, we were flying a kite with our four-year-old daughter on a very bright and windy afternoon. The light was harsh, but the contrast and saturation were excellent, which I find always works well for an action shot. My wife took a few photos of my daughter and me with the kite and the dramatic clouds in the background. I think there are two key factors that make these photos work: good composition (taking many shots really helps – one needs to expect many of them to be throw-aways); very bright lighting (it helps with sharpness, saturation and contrast).

On reading

“To read with diligence; not to rest satisfied with light and superficial knowledge,..”
– Marcus Aurelius Antoninus, “Meditations“

It is commonly argued that in reading, as in any kind of studying and almost any kind of activity, the Pareto principle dictates that 80% of the results (e.g. knowledge) can be obtained during the first 20% of the time (or 20% of the total possible effort) spent on the activity. After the initial 20%, the returns are progressively diminished, so that larger amounts of time spent reading provide only incremental increase in knowledge.

While tis is probably true, I believe, or at least would like to believe, that striving for deep, fundamental knowledge is what separates true experts from lay people. Of course, the question of whether it is wise to focus on obtaining expertise in a narrow field (i.e. “niching down” in photography) remains open. However, if this niche is learning itself, and the skill that we are mastering is our ability to learn new skills, the rules start to change. Learning, according to Naval Ravikant, among others, is a wild card, a joker, in a sense that learning can be traded for any skill that is needed at any given point in life. From this perspective, it is easy to agree with Stoics, who taught that “Of all men they alone are at leisure who take time for philosophy, they alone really live;..” (Seneca, “On the Shortness of Life”).

Journalling

Journalling has many benefits, as has been pointed out many times by various illustrious writers. Blogging, which is very different from journalling in that it is a public expression of thought, while journalling is private, is also very useful. It provides an opportunity to practice formulating and publicly expressing an opinion with the full understanding that this opinion will be permanently recorded somewhere in the proverbial cloud.

Another way of journalling, which is somewhere in between between private journalling and public blogging, is keeping a diary as a record-keeping activity. Today, I heard an interview of Robert Rodriguez, who made a strong case for this habit. Having a daily record of the significant events of every day makes a powerful tool for parenting, personal development, work, etc.

I think that taking family photos on a regular basis (ideally daily) serves the same purpose. In my personal case, I find that having a large, easily-accessible database of images that commemorate the significant events in our family’s life is very valuable. Looking through these photos with my four-year-old daughter (I have the images from my Flickr photo stream scroll as a screensaver on the TV in our living room) shows that I tent to over-estimate both my daughter’s and my own memory span an ability to recall small details and events that seemed significant at the time they were happening, but vanished from our minds just a few weeks (not to mention, months and years) later.
