You need a power bank.

Filed under: Travel — spanjavan @ 5:51 pm

As I have become more and more dependent on my mobile phone for daily activities, stretching the battery life has become a challenge.  Simple uses like photo taking and map navigation are big power drains to the phone.  I found myself on many occasions that I had to restrict my phone use to make it last enough for my need.

Last year I decided to get a power bank.  It turned out to be a very good decision for it quickly became indispensable during my most recent trip.  There were so many days during my 3-week trip that I left the hotel early in the morning and did not have access to a power outlet again until the evening.  I simply put the power bank in my messenger camera bag with my iPhone and plugged in the charging as needed.  Sometimes I even take photos with the iPhone connected to the charger.

I almost always open the Google map app while riding on a taxicab and such.  It’s a good way get the bearing on the location.  Using the map on the mobile phone doesn’t cost a lot of data usage but it is a big battery drain.  With the power bank during the previous trip, I just left the phone connected to the power bank while running the map app.

When choosing a power bank for traveling, more power isn’t always better because more power means more weight and larger size.  For a single phone use,  a power bank of 5000-10000 mah (milliampere-hour) capacity with the weight of 5-8 ounces will work well.   For recent the generation of phone models such as the iPhone X and Galaxy s9, you shouldn’t go below 5000 mah.  These new phones have a larger battery and will need at least 5000 mah for a full charge.

Unless you don’t plan to charge your power bank after use nightly, any capacity above 10000 mah is unnecessary.   As you go for a higher capacity, the more weight you’ll have to pack and carry.  From my travel experience, you’d want to avoid packing more weight than you need.

The Decisive Moment of The Window Cleaning

Filed under: photography — spanjavan @ 11:26 pm


You’ve probably heard of the term decisive moment, the moment you decide when it’s the right time to press the shutter button. This term has been around even before the time the (film) SLR was invented.  A roll of film for an SLR contained only 36 frames.  Each shutter press had to be selected very thoughtfully. Although the term decisive moment is somewhat less meaningful in today’s digital era, it is still relevant in conveying a recommended practice of giving a thoughtful consideration in selecting the timing to trigger the shutter.

Another related practice is about working the scene.  In a situation where you have time to work your composition, you can explore different zoom level, camera position, etc for the framing options.

The picture above is of a window cleaner hanging in a harness.  He cleaned each window pane while making his way down from the top.  When he first appeared while still high up, I immediately thought of capturing him in action.  The idea of shooting him with the sky in the background was appealing.  Because the event was developing at a rather slow pace, I had some time to plan for the shot.

Several thoughts came to my mind (not sure which came first though).  Here are a few of them.  One was about the vantage point to take the photos from, and I ended up taking the photos from different vantage points. Another one was about which window pane to put him in that would give me the best composition. As he was making his way down and swinging from side to side, I had to decide on the best time to press the shutter button. I tried to get the posture as well as the position within the window frame.

Below are a small number of examples of shots that I didn’t pick.

Taking Photos Outside of The Golden Hour

Filed under: photography, Thailand, Travel — spanjavan @ 12:35 am

It is a conventional wisdom that the optimum time window to get good shots is around sunrise or sunset, generally referred to as the golden hour.  The condition becomes less ideal as the sun is higher up in the sky.  There are even suggestions that outside of this window, you should just enjoy other activities instead.

As a hobbyist, photography is just part of what I do when I travel during my time off from work, which happens only a few times a year.  I also rarely travel alone.  I take advantage the golden hour when I can, and when it’s not in conflict with other activities.  However, I can’t afford to limit my photo activity to just a narrow window.  I do believe that good shots are possible throughout the day (and night).  As long as there is light, there are opportunities to take photos.

My approach is to take my camera with me when we go on our outings. I have a medium camera bag that is small enough not to get in the way and big enough for my APS-C mirrorless plus a few lenses.   My lenses cover the focal length from 10 to 70 mm. I use a wrist strap for the camera and pretty much leave the lens cap off.  I feel like I can respond more quickly and have more positioning flexibility with the camera in my hand rather than hanging around my neck.

The Sitting Buddha in the Nakhon Lampang below is almost 100 ft tall.  This HDR photo was taken in the middle of a hot afternoon.  I lied down flat on my back and aim almost directly up to get this composition. This harsh lighting condition would typically considered as unsuitable for photo taking.


The photo below is of a bluebonnet field in Ennis, Texas.  I took this photo late in the afternoon under a partly cloudy sky.  The camera was positioned just a few inches above the flowers. The soft light from the cloudy sky was a bit flat, but there were enough visual elements to make the picture interesting.  There are only two dominant shades in this photo but they complement one another really well.


Below is a train track at the Railway station in Nakhon Lampang shot sometime in the mid afternoon under a partly cloudy sky with some sunlight managed to shine through.  Several parallel straight lines created visual diagonal lines toward a converging point further inside the picture.


Below is the Klong Dan floating market in southern Thailand.  It’s located partly in the Song Khla Province and partly in the Nakhon Si Thammarat Province.  This is a popular floating market for the locals.  I took this photo around 3 pm under an overcast sky.  I took advantage of water reflection and spatial separation between the row boat and the rest of the scene in the background.  I used a prime lens with the aperture wide open to take advantage of the separation and to keep only the row boat in focus.


Below is the interior shot of the main chapel of the Marble Temple in Bangkok.  I took this shot in the early afternoon.  Pattern on the floor created suggested diagonal lines leading to the principle Buddha Statue. By being inside, I totally avoided dealing with the harsh sunlight.  Instead, the windows on both sides created a soft indirect light that nicely blended with the artificial light sources inside.


Good lighting conditions can exist throughout the day.  It’s just a matter of conditioning our eyes to see these lights photographically.  Even harsh light can sometimes create an interesting visual effect. The ability to capture good photos in different places throughout the day allows you spend time with your friends and family and enjoy shooting photos at the same time.

Capturing People In Travel Photography

Filed under: photography — spanjavan @ 8:25 pm

People are part of the scene. It doesn’t make any sense to try to avoid them when taking photos. I fully embrace the idea of including people in my photos. Oftentimes, They become the main subject.

We all have a good idea about the size of a human body. Simply having a person or persons in the photo can provide an overall sense of scale. In an urban setting, how they dress, their actions, and their facial expression can be a good reflection of locality.


In the shot above, having the tourists in the shot gives the sense of size to the Buddha statue.


In the shot above, the gesture came when the man on the tricycle turned around to check me out.


In the shot above, this couple both wearing read, arrived on a motorbike and started to take some selfie pictures with the mosque.  Instead of trying to avoid capturing them, I made them and their motorbike part of the composition.


The man in the above photo came to worship the Guan Yin statue at a Chinese temple in Hat Yai.  When I saw him raised his arms, I quickly composed and took the snap.


This old lady sells Thai desserts off her row boat at a floating market in Bangkok. She wears a classical style straw hat with a flat top that used to be commonly worn by farmers back in the old days. I spotted her from the distance and rushed toward her to take this photo.

Shooting in an uncontrolled environment can be a hit or miss thing.  It’s just part of the process.  In the digital world, taking bad shots doesn’t add to the cost.  However, it’s still very important to be deliberate about each shot as much as possible, and not just spray and pray.  One key thing is to eliminate/minimize distraction.  I often take multiple shots while trying to anticipate the moment as the scene continues to change.   The majority of the time because the scene never materializes as I expected, I would come out empty.  Every once in a while, I would get shots I like.

Camera Gear Packing For My Upcoming Trip

Filed under: photography, Travel — spanjavan @ 2:09 am

I’m about the take off on a 3-week vacation to Thailand.  This is not photographic trip but I will look for opportunities to take photos when practical.  I have a Tamrac backpack with wheels for my gear that is good for a carry-on.  As in the past trips, I’m bringing 3 cameras with me —  a Nikon D750 DSLR, a Sony a6000 mirrorless and a Sony RX100 M3.

I use the D750 for the static shooting of subjects where I take the time to compose each shot.  The shooting may involve the use of a tripod.  Occasionally, I use it for a photo walk If I’m in an area where I feel comfortable enough to carry it around.  The lens of choice on the camera for most outdoor shooting is a Nikkor 28-300 mm zoom. Although I own a few prime lenses, I rarely take them with me on my trip.  The second lens for the D750 is the Nikkor 18-35 mm wide-angle zoom.  These 2 lenses pretty much cover most of the occasions.

The Sony mirrorless, with it being relatively light and compact, is great for urban and street photography, particularly when there are a lot of people around. I recently replaced the 16-50 mm kit lens with a considerably larger and heavier 16-70 mm lens.  I took it out for a photo walk recently, and it seemed to be more noticeable to people than the kit lens.In addition to the 16-70 mm, I also bring along the 10-18 mm wide-angle zoom lens.  The thing I like a lot about the a6000 is the tilting screen that allows me to easily vary positions and orientations and shoot from different points of view.

The Sony RX100 M3 being so tiny that it doesn’t really take up any packing space.  I tend to keep it my pocket we go out for the daytime sightseeing. The camera’s ready time is not very good.   but it’s nevertheless a very versatile camera to carry around.  Having a quiet electronic shutter is its big advantage.  I can aim close to a subject and press the shutter button without causing an alarm to anyone.

My iPhone 6p that I acquired this past summer, despite of its limitations, has been getting more use as a camera.  I use the camera inside the Lightroom Mobile app the majority of the time.  What I like about the Lr Mobile is the support of the raw dng format and the auto sync via the cloud to the desktop.  After the photos are sync to my desktop catalog, I can simply delete then in Lr Mobile preventing the photos from eating up the storage on the iPhone.  The upcoming trip will be the first with the iPhone6.  We’ll see how well it works out.

In addition to my camera gear, I’m bringing along a laptop and a portable hard drive.  My Tamrac backpack has a laptop compartment that can comfortably fit mine.  I generally transfer the photo files on the camera’s SD card to the computer as soon as I have a chance to in order to free up the card. However, I am not always in a hurry to post-process them.

Other accessories I always bring along are a tripod, ND lens filters, a remote control, a shoulder bag, a small led flashlight and plenty of disposable lens wipes.  These accessories are for low light situations.   My tripod is a 4-section carbon fiber that collapses down to under 2 ft long, easily fit in a checked baggage.  I’ve recently bought a wireless remote control that can be used with both my D750 and a6000 with a swap of the connecting cable.

This is the gear set that works for me based on my current shooting interest.  Although the set can change at some future time, I don’t see any need for an upgrade anytime soon.  At least not within the next year.

Photo Walk Along Lamar Street

Filed under: photography, Travel — spanjavan @ 10:27 pm

After finishing with my visit around the Omni hotel by the convention center, I decided to walk along the S. Lamar St. hunting for some night photos.  When I do a photo walk with my Sony A6000, I typically carry two lenses — a 10-18mm and a 16-70mm.  All the photos posted here were shot in manual mode. Auto mode wouldn’t work well for me due to its tendency to overexpose  bright light sources.

As soon as I approached the first corner, this red car came to a stop for the red light at the intersection I was crossing.  The car was fairly well lit by the street lamp.  I like the red and green (from theBank of America Plaza further away) color combination.  So I lowered the camera to about the same level as the car and took this shot with the green outline of Bank of America Plaza in the background.   There were two people in the car but I didn’t pay much attention to them, and neither them to me.  From their point of observation, I was actually aiming my camera toward the street behind their car.

Just another block down on S. Lamar St, the horizontal purple lines gave a nice interaction with the green vertical lines.  With the camera tilting upward, I composed the two buildings as diagonal lines.

Further down the street was the Greyhound bus terminal.  I liked the overhead neon sign and spent some time figuring out the composition and tried a few shots.  In the one I eventually picked below, I intentionally lined up the Greyhound neon sign with the green vertical lines of the Bank of America Plaza.  I just like it better compositionally when they are parallel.

Crossing to the east side of  S. Lamar, I got a good front view of the building.  I liked to Greyhound logo above the building entrance and took the shot below.  One tricky thing about capture artificial lights at night is managing the white balance.  Shooting raw gives me the flexibility to adjust the white balance during post processing.  In the photo below, I left the exterior lights as shot and added some warmth to the fluorescent light inside the building.

I saw this blue Christmas tree in front of the Bank of America Plaza on Main St from afar and decided to check it out.  As I reached there, I noticed the reflection of the tree from the top side of the Bank of America Plaza’s building sign on the sidewalk.  I decided to use it as the foreground in the shot below.

Beyond The Rule Of Thirds

Filed under: basic photography, photography, Travel — spanjavan @ 7:04 pm

The rule of thirds is a very simple idea on composition that can be easily explained without getting into a more complex concept of visual flow and balance.  You draw two imaginary vertical lines to divide the frame into three equal vertical sections and two imaginary horizontal lines to divide the frame into three equal horizontal sections.  One of the 4 intersection points becomes a sweet spot for placement of the main subject.  The illustration below is from Wikipedia.


Source: Wikipedia

As explained in the Wikipedia article, the rule of thirds is not a governing rule.  It’s a rule of thumb based on a general practice of the visual balance that often works, but not all the time.

When I compose my image, I generally start with the idea of placing the main subject off the center and then look for other visual elements to make up for the visual balance.  I don’t make it a mandate that the subject has to be at one of the rule of thirds sweet spots. Although that ended up being the case a majority of the time, I treat the rule of thirds as composition tool rather than a guiding principle.   Every once in a while, I would end up with something deviating from it.  Below are a few examples of such case.

The picture below was taken in Southern Thailand.  It’s of a fisherman taking his long-tail boat out early in the morning to collect fish traps he laid the previous night.  I placed him well left of the rule of thirds sweet spot but the composition works for me, perhaps because of the counter balance from the boat that has a visual draw toward the right.  If I placed him right on the lower left sweet spot, I would have left too much negative space on the left side of the frame that tilted the overall visual balance toward the right.



The second picture below was taken in the evening at the Ronald Kirk Pedestrian Bridge in Dallas, Texas.  The bike stands out as a stationary object among blurry moving people.   I placed it well left of the rule of thirds sweet spot because the overall visual balance from the elements from the right works out better for me.



The picture of tree and sunrise below was also taken in Southern Thailand.  I placed the sun almost in the middle of the frame. The sun with its radiating light essentially fills the entire frame.  This image literally breaks to rule of thirds. To me, this composition better conveys the idea of intense sunlight.



The rule of thirds, being easy to understand, is an excellent learning tool on beginning composition and on occasions a good starting point for composing an image in practice.  Beyond that, instead of being concerned about conforming to the rule of thirds, it would be many times more fulfilling to rely more on your creative instinct and experience to make the final decision on what your image will look like.

  • 1 cup of steamed rice (white or brown)

Feel free to vary the proportion to taste.


  • onion: cut off the root, cut into 1/2 inch pieces
  • mushroom: cut into thin slices
  • chicken: cut into pieces, no more than a 1/4 in thick and 1 in long
  • (optional) marinate cut-up chicken with 1/2 table spoon of light soy sauce
  • mix water and flour in a small bowl, stir well until totally mixed, no lump

  • heat oil in an 8 in frying pan until hot
  • add chicken and stir continuously until meat turns light and pink
  • add onion and continue stir for a few minutes
  • add mushroom
  • add soy sauce
  • continue to stir until mushroom is full cooked and become soft
  • add chicken broth (or just water) lightly stir to boiling
  • If needed, stir up the flour mixture in the blow for uniform liquid

For 2 serving, double the amount of the ingredients and cook in a 10-12 in frying  pan.

It’s important that the frying pan is not too big otherwise the ingredients will spread out too much.

Variation of ingredients

Mushroom can be substituted with different kind of mushroom but avoid rehydrated dried mushroom. Sliced bamboo shoot can also be used.  Substitute by volume, not weight.

Different meat such as tenderized beef, peeled shrimps, or oysters.  Substitute by weight.

Trang’s Hole In The Wall

Filed under: Food — Tags: , , — spanjavan @ 1:21 pm

I found this small obscure place by chance.  Our hotel didn’t provide breakfast so I went out searching near by area for some food.  This place is run by a team of uncle (top picture) and niece.  The bottom picture shows the niece standing next to her chef uncle.  The niece takes order and the uncle cooks. For my readers who are not familiar with the term, a hole in the wall refers to a small and obscure restaurant (or bar).  Although the term itself doesn’t say anything about the food quality, the discussion of a hole in the wall is usually about a place the serves good food.

I ordered a take-home to bring back to the hotel so I could share with my wife.   It turned out they didn’t have any plasticware.  She was kind enough to let me have a set of aluminumware.  I felt a bit guilty that she did that without charging me for it and told her I would bring it back.  She gave me a smile and told me not to worry about it.  When I got to taste the food at the hotel,  it was really really good.  The meat (pork meat and internal organs) was tender and the flavor was just right.



The Chef


The next morning after getting all packed up and ready to checkout from our hotel, we came out to the restaurant to eat.   The niece recognized me, and I told her that I was returning the fork and spoon from the previous day.  My wife and went inside and sat at the table toward the back. (The middle picture was taken right about where we sat look back toward the front.  This time we order something soupy and found out how good the soup was.  While we were enjoying our noodles, there were not that many dine-in customers.  However, there was a constant stream of take-home customers at the front.

Hole In The Wall

Inside Looking Out


While walking out after finishing up our meal, I had a chance to chat with the niece and learned a little more about this place.  I complemented her on the meat and the soup and noted my observation to her that the restaurant didn’t have any name. It turned out that the regulars here referred to the restaurant by the uncle’s name which makes perfect sense. Sorry, she told me hist name but I’m not sure if I remember it correctly.  He was close enough to hear the conversation but through out just kept focusing on filling orders.

She and her uncle operate the restaurant, and the uncle was obviously the chef. The picture below shows the niece standing side by side with her uncle. They are opened around 5:30am every morning with the first customer usually shows up around 6am.  They will continue selling until they run of the food they had prepared for the day.  They usually run out of their supplies between 11am and 12pm.


The Chef

If you like noodle dishes and happen to be in Trang, I’d suggest you give this place a try.  but you need to get there early enough.  If you are late they might be sold out already.  The location is shown on the map below.  It’s on Kan Tang Rd across the street from the Krung Thai bank, only a short walk south from the Rama VI intersection.  It’s the only restaurant on that side of the street so you can’t miss it.
