The K.I.S.S.R Principle - Composition Basics


Till this very day, I am a firm believer that composition is the key to any outstanding photo, regardless of the camera or gear you use. Saying that your equipment is not sufficiently good for taking breathtaking shots is merely conjuring excuses to be lazy. Needless to say, your camera is just a tool, and you should use your tool to the best of what it allows you to do, limited only by your creative potential.

So what then is this thing calld the  K.I.S.S.R principle? It stands for 'Keep It Simple Stupid...Really'. If you have noticed, those pictures we see in photography magazines that have the 'pop' tend to keep composition down to a bare minimum. Needless to say, one of the fast way to learn how to take good picture is to observe how other experienced photographers do it. For a start, a good place to start looking is Flickr. Take time to observe their photos. Besides Flickr, another good place is Facebook, because Facebook is flooded with brilliant examples of horrible photos that are painful to look at. Seriously. What we need its a means of learning from both the best and the worst. Knowing how to take 'horrible' photos is a good start to learn how to avoid the pitfalls of other photographers.

In this article, I will outline some of the compositional techniques employed by experienced photographers. Please not that these are merely aids, and like most rules out there, are meant to be broken. For the purpose of simplicity, I will not go though other compositional aids such as the Rule of Thirds as there are plenty of topics about it on the Internet.

Simplicity
Keep your composition as simple as possible. Composition is the technique of arranging subjects in a picture. Ideally, try not to have more than 3 subjects in a photograph. Having too many subjects dilutes the context. In photography, less is usually more.

Context
The context of a picture is the part of the picture that tells a story. A good picture is one that has a punch line. In other words, one look at a picture and it should tell you something about it straightaway. A good way to preserve and enhance the context of your photo is to arrange the subjects in the frame such that they tell a story. For example, a lone silhouetted figure sitting on sandy shores of a beach overlooking the sunset can make for a striking photo. Ask yourselves questions like, "What is it that I like about this?", or "Why am I taking a picture of this?". A good photo always has a strong but simple punchline.

Colors
Look out for color themes when framing your shot. Different colors tend to convey different mood. Does the color of your main subject stand put of the crowd? Or does your subject blend into the rest of the scene? Does the scene look better in monochrome? Red tends to communicate warmth, energy and force. Green symbolizes freshness, youth and vitality.

Texture
Texture is important in conveying information about the nature of materials. Without texture, everything will just look plasticky and boring. Everything would be just blobs of color with nothing much to tell.

Contrast
Contrast in this sense is subjective, because it can be contrast in term of color, subject, context and even texture. What good is contrast if it can be so subjective? For a start, contrast helps us to get things noticed. Think of the red-dressed girl in a crowd of black-suited executives crossing at a busy intersection, or the wrinkles on a grandmother's face, as she hugs her 3 year old granddaughter. These are just examples of how contrast can be put to your advantage.

Harmony
Harmony is the opposite of contrast. While harmony is similar to contrast in that it applies to the choice of color, texture and context etc. , harmony is different in that it is about similarities. Think of the lush green forest and all the shades of greens in between. Harmony is about conformity and control.

Mood
This is a tricky one. It is a cocktail of the above-mentioned points and matter of personal taste and understanding of the context of the situation.

The Wrap Up
Composition is a very much neglected topic by many beginning photographers. Newbie photographers often get stuck at figuring how their cameras work, and are too concerned about which settings to apply, or which lens to use. All this can be distracting and can likely be discouraging when you do not get the intended result. Instead of taking too long to figure what ISO or aperture, or shutter speed to use, photographers are encouraged to focus on the subject to be photographed. This is not to say that it is not important to know how your camera works, but that you should not be distracted by it. That being said, leave all the technical mumbo-jumbo at home and put on your creative thinking cap when you are on the field.

Fairy Cave Revisited


It had been quite a while since the last time I set foot in Fairy Cave. The last visit there proved somewhat fruitless due to the fact that I relied solely on my camera's high ISO capabilities to shoot in near pitch dark conditions, for forgetting to bring my tripod. The ensuing result were photos that were a little on the soft edge due to extensive in-camera noise removal.
Photographing the interior of the cave proved more difficult than the last time. Not only was the light intensity lower, but it has only just stopped raining and it was so extremely humid inside! Imagine the viewfinder fogging up each time I looked thought it! And the stench inside the cave was oh so unbearable too.

But I digress; complains aside. The stuff I brought along with me were:
  1. Canon EOS 500N film SLR.
  2. Nikon D7000, my trusty companion.
  3. My tripod, with plastic socks made from cut up plastic bags. (I couldn't bear the idea of bat's s**t sticking onto the legs of the tripod :) )
  4. A small torch, which really was the flash of my mobile phone.

Perhaps the most difficult aspect of photographing the cave was that there was not enough light to judge my composition, thus making the right judgement very difficult if not impossible. The low light also made it difficult to autofocus. Thank goodness the Nikon had all 39 autofocus points doing their magic.

Another thing about the lighting in the cave was the heightened contrast between the dark and light areas. It was virtually impossible to have a single exposure capture the entire range of light so I took several exposures, ranging from 30 to 2 seconds, and made a HDR image out of them. Shown above is an HDR composite image.

Keeping the camera still during the long exposures was one thing considering that my tripod was a flimsy and cheap one. The last time I took it out for some night shoot it literally swayed in the wind! In the cave, it was not so much of a problem with the wind, but I was hoping to have a tripod that could hold kilograms of gear without worrying that it will tip over, especially when you can't see that we'll in the dark.

Here are the individual Jpeg images before I combined them to form a HDR image.
 

Exposure: 25 seconds. Aperture: f/5

Exposure: 10 seconds. Aperture: f/5

Exposure: 5 seconds. Aperture: f/5

Exposure: 1 second. Aperture: f/5

Exposure: 30 seconds. Aperture: f/5. Deciding I needed a bit more texture and detail for the cave's floor, I decided to lengthen the shutter duration.


And here are the HDR images.

Film or Digital?

It's been a while since the last article I wrote on JPeg or Raw - Part 1, and now we have yet another debate to bring to the table. It is a wonder as to why the topic as to which one, film or digital, has, till now, been a subject of much heated debate. A little bit like comparing apples to oranges perhaps? Let us have a look at some key differences between film and digital, and in a while, we will study the advantages and disadvantages of each.

A recent film photograph of my dog chewing an old slipper

A Short History of Film
Film has been around for so long, that it has been subjected to many many years of innovative breakthrough. It all began when Louis Daguerre who developed the first practical photographic methods, called 'Daguerreotype', which involved the use of sensitized silver-plated copper (the 'film') and fumed with iodine vapor. Exposures were extremely long, as long as eight hours! This proved to be somewhat impractical but was used to capture landscapes. The process and chemicals involved were adapted and improved over time. In 1839, the rights for the daguerreotype was sold to the French government.

Fast forward to 1889, George Eastman, founder of the Kodak Company, invented the roll film. The rest was history, and film continued to dominate for more than a century.

The Digital Revolution
The early digital cameras in the market were simply horrible, suffering for a myriad image-quality issues, resolution being one of them. However, in years that followed, tremendous improvements were made in digital imaging and digital has come to be the medium of choice for professionals. Improvements were made in terms of resolution, dynamic range and color, just to name a few.

Film versus Digital

To say that digital has somewhat 'caught up' with film would be far from the truth. In order to draw a fair comparison, you need to first see the big picture. I have decided to split the pros and cons into a few sub-categories. For the sake of simplicity, I will only talk about the qualitative aspects of film and digital.


Comparison:
Detail Retention:
Film: Better at retaining detail, albeit grainier than digital, regardless of ISO sensitivity of film used.
Digital: Smooth and buttery texture. In other words, very clean images at the lowest ISO sensitivity. Loses some detail through interpolation and other internal processes, which vary according to make of camera.

Film grain is more evident in film and is especially noticeable in enlargements. Notice how well detail is preserved.



Dynamic Range:
Film: Superior dynamic range to digital. Film overexposes gracefully, and does not blow out to white (as in digital).
Digital: Dynamic range somewhat limited, and causes highlight 'clipping'. However, tremendous improvements have been made in this area in recent years.



Better dynamic range translates to better handling of extremely bring and dark areas


 Resolution & Image Quality
Note: This one is subject to some degree of controversy, because it is one of the most misunderstood. The hype created by the marketing departments of many camera makers led us to believe that resolution, in megapixel terms, was a measure of how 'good' a camera is. In other words, we were led to think that 'more is better'. Today, most of us know that is hogwash. The definition of resolution versus image quality is thus a complex one because a myriad of processes go on in a digital camera that determines how 'good' an image will turn out to be. To put it quite simply, two cameras can spit out images of the same resolution, but the quality may not be the same because different cameras may employ different image processing technologies. For the sake of comparison, I will do a basic comparison in lieu of detailed analysis.
Film: Resolution is virtually infinite, on the film itself at least. Putting a 'megapixel' cap on film would be an insult to a hundred years worth research and development that has gone into perfecting it. The quality of the final image will depend a lot on the equipment used (film scanner, enlarger, focusing lens), and of course, the size of the medium (in this case, the film). It is worthwhile nothing that while film has more grain (see the above, on 'Detail Retention'), it (the grain) plays an important role in the aesthetic quality of film.
Digital: Resolution of a digital sensor is finite. A digital camera that is rated to have '16 megapixels' will produce an image that is composed of those number of pixels (usually an approximation of that figure). Digital images tend to be 'smooth' and 'silky' in texture, with grain usually almost absent at the lowest ISO settings. The camera's processor may perform additional image processing such as noise reduction, which smudges texture and fine detail, making the 'megapixel race' somewhat irrelevant at this time of writing.


Post-Processing
Film: Besides the traditional dodging and burning, 'editing' film was a difficult procedure and was often performed by skilled individuals.
Digital: It has never been easier to get creative, with Photoshop and a whole array of digital tools at your disposal.


Conclusion
To sum it up, comparing film with digital is really like comparing apples to oranges. Each has it's share of advantages and disadvantages. The choice between film and digital is a matter of personal preference. The aesthetics of film can be difficult to reproduce in digital format, but digital photography has made the hobby more popular hobby than ever before.

JPEG or RAW? (Part 1)


JPEG or RAW? It seems that this is an ongoing debate with no clear conclusion in sight.

While doing a photo shoot for a commercial project recently, I had to decide whether or not to shoot in raw. Being somewhat of a purist, I used to abhor the idea of shooting in raw because I didn't like the idea of spending too much time with post-processing work. I believed that it was better to get most of the work done right out of the camera.

After all, you can't do much 'editing' on film right?

Wrong.

Ansel Adams developed his zone system to push the dynamic range of film to the limit. For that given reason, the same could be done on a 'digital negative', which is what the raw format sometimes called.

There are several advantages to shooting in raw:
  • Shooting in raw gives you more latitude in adjusting the image in post production.
  • Raw images are actually 'raw', unprocessed and uncompressed data collected right off the CCD or CMOS sensor of your camera. Because the data is in its purest form, it is virtually devoid of heavy-handed compression and noise-removal, usually done by the camera's CPU, which is necessary to produce Jpeg files.
  • Images generated from raw files tend to retain finer details because the processing is done by your computer, and not your camera's processor.

Shooting in raw has its drawbacks as well:
  • Large file sizes means you must be prepared to swap memory cards often, unless you have one of those cards that can store a trillion images (just kidding!).
  • Raw files cannot be read without proprietary software. In other words, raw files are 'non-standard', which means they vary according to the choice of camera model and manufacturer. In order to read these raw files, you will need to use the software that comes bundled with your camera. Adobe's Camera Raw plugin is an impressive alternative that allows you to read raw file formats from a host of camera manufacturers. There is also growing support from the open source community in recent years.
  • It usually takes more time to work with raw files. Raw files are, well, raw after all.

Now let us have a look at some pros and cons of working with Jpeg files:

Pros:
  • Smaller (relatively) file sizes makes Jpeg files more economical to store, although they seem to be becoming larger as manufacturers pack more megapixels into their camera sensors.
  • Jpeg files are easy to work with. Because Jpegs are universal, virtually any device can them.
  • Perhaps most importantly, Jpegs are ready straight out of the camera. Post-processing is optional.


Cons:
  • Not much room to wiggle. With a Jpeg file, you are left with limited room to modify the image.
  • Jpegs images produced right out of a camera tend to be of lower quality.

That being said, the choice between shooting in raw and Jpeg is entirely yours. Professionals may shoot in raw because it allows them more freedom to make corrections later. On the other hand, if you do not intend to do a lot of post-processing work, then shooting in Jpeg is fine.

I will a closer comparison between Jpegs and Raw conversions in part 2 of this article.

The Cold Northerly Winds - The Last Frontier of the Cold War


My visit to Korea was full of surprises (sprained knee included). I have included photos of my trip there in the gallery section of my blog, so you can have a look there. To cut a long short, I will first write about my visit to the de-militarized zone (DMZ). (By the way, the pictures you see here are not in chronological order. You can check out more photos under my photo gallery. You can access it via the navigation bar above.)

Panmunjom, the village near the DMZ, is located some 56 kilometers from Seoul.

The Cold War had always intrigued me. In fact, knowing full well of the potential danger that lies ahead of me, curiosity got the better of me, and after much thinking, I decided that it was somehow worth the risk, to embark on a once-in-a-lifetime journey to see the last frontier of the cold war.

Unifying a divided country. It takes two hands to clap


Just how risky you may ask? It depends. Firstly, the two Koreas are still at war, technically. Secondly, you may be asked to sign an indemnity form, to indemnify the United Nations Armistice Committee and the US Army against anything tragic that might happen (touch wood) to you, if you decide to visit Panmunjom and the United Nations Joint Security Area (JSA).

Mount Dora Station. The last station in South Korea, connecting to North Korea.


A visit to the DMZ is not complete without a tour guide, as a guide can be quite informative. What about going alone? Nope, getting about on your own is just not possible, due to the inherent danger that lurks ahead. Mines are scattered all over the place in the millions. Barbed wire fences, machine gun turrets. Anti-tank explosives. Well, you get the idea.

Prayers for a peaceful reunification of the two Koreas.


Sounds serious enough to deter you from ever visiting the place? It shouldn't. A visit to the DMZ is basically divided into two parts, depending on the tour you are following. The first part is the 'normal' tour, which takes you to several places of interest near the DMZ (more on that later). The second part, is the one you should prepare for in advance. The second part involves a visit right into the heart of the DMZ. Yes, right into the no-man's-land, the 4 kilometer wide buffer zone that separates the two Koreas. People were killed there before, so do behave yourself! The tour bus will stop at one of the checkpoints and an American GI will do a security check on everyone in the bus before you are allowed to disembark the bus and head for Camp Bonifas. The place is, at least from first impressions, quite tourist friendly, and you can't be faulted for thinking that the place is a tad bit too touristy to be a war zone, but the JSA authorities have done much to make you feel right at home over there. Nonetheless, the element of danger still lurks, and the threat of an invasion from the north is very real. You have been warned.


The JSA Visitor Center, Camp Bonifas.


If you do intend to actually get into the JSA, it is paramount that you prepare your passport. Be informed that citizens from Malaysia and Singapore, among other countries, will need to submit scan-outs of their passports at least one week in advance to the Panmunjom Tour Office at the Lotte Hotel near the Korea Tourism Organization office. The background check is necessary as this is a high-risk zone and I suppose you can't have someone with malicious intent going there to start an second Korean War. Jokes aside.


The Joint Security Area.

 The JSA area (as seen above) is the real deal. That white building you see up ahead from where the blue conference buildings stand is the Panmungak, the North Korean JSA office. You you observe carefully, there is this pesky North Korean officer scrutinizing us through his binoculars. Makes us look like museum exhibits or wild animals in cages. Sheesh...

Photography in the JSA is limited to certain areas as they can't afford to have photos of the site leak to the North Koreans which can prove to be strategically advantageous to them.

I could go on writing  but I think I'll stop here. I'll leave the rest for you to discover on your own.

Blogger's New Look - Inteface Done Right


Since Eric Schidmt stepped down as CEO of Google, there have been some incredible changes in the way Google works. Among these sweeping changes include a 'beefing up' of the user experience overall, of Google's services, notably, Blogger and Google Photos. Seems like Google is finding an avenue to retire their Picasa Web services, but that is just a wild guess.

Having been blogging for these couple of years, I had for some time been deliberating as to whether or not I should make a switch for WordPress. However, the changes made to Google's blogging platform has seen a more user-friendly interface, making heavy use of AJAX and HTML 5.

As a result, saving your drafts and posting them can be done in a flash. No waiting for whole pages to reload. Yay!

Happy blogging everyone!

Switch is switching!

Pardon the rather uninspiring title. I was given the privilege to cover the event for the day, and what might be that big happening for that day you might ask?

Switch in Kuching is now an Apple Premium Reseller. Yay!


Switch, an Apple Premium Reseller (no, they don't sell fruits) traces its humble origins to Gelugor, Penang, West Malaysia. Following Apple Inc's phenomenal comeback, Switch has expanded its presence through the entire country and has recently made inroads into our beloved Hornbill state of Sarawak.

Switch was, until very recently, only an 'authorised reseller', meaning they were limited to selling only certain Apple products, but now being a premium reseller, you now have access to Apple's full range of premium products. Not bad for a first in East Malaysia.


Compared to their old corner lot, the new lot they currently occupy is HUGE, at least as far as floor space is concerned. The store does seem a bit sparse, but then, every measurement is made to Apple's standard, so it could be a requirement for the store layout and design.

iPad2..wheee..

The new store is adorned with Apple's trademark colours of white and black. iPads, iPods and iPhones lined up neatly on white display stands.


Participant participating in a Fruit Ninja competition. Winners walked away with a goodie bag!
It was a very busy day for the Switchers (Switch's staff are called 'Switchers', at least that is what their T-shirts tell us). The day was packed with activities ranging from a Fruit Ninja competition during which winners walked away with a goodie bag each. Prize allocation was based on who is able to score the highest. I could barely make it past the 170 mark!


It was unfortunate that I had to leave early, but all things being equal, we now know where to get the latest Apple gadgetry. Long live Switch!
