Walking fish

Walking fish, formerly known as Mudskipper, is an amphibious fish that can use their pectoral fins to walk on land. Here is a short clip showing a walking-fish crawling on mud and hiding in its burrow in the mangrove conservation area of Sam-Roi-Yod National Park, Thailand.

Panning Photography

Panning is a technique where you pan your camera along with the moving subject to capture the subject relatively sharp while the background looks blurred, to give the feel of movement and speed.

After reading few online articles, I thought to give it a try. On the first day I ended up with awkward images in all. But, on the second day I got few shots which are 'just ok' kind and are given below.






I took these shots with my camera hand held. I felt that hand holding camera gives the freedom of tracking movements in all the possible directions unlike mounting on a tripod.

The lessons I learned are,
  1. Have to set the focus mode to AI Servo (Continuous focus tracking),
  2. Have to select the appropriate slow shutter speed (For example along the side of a 30' wide road where the speed limit is 40 km/h, I ended up with around 1/15 sec shutter speed after many trials),
  3. Have to track the subject smoothly through the view-finder with half pressed shutter-release and then fully press the shutter-release when the subject reaches a nice view, and keep tracking smoothly,
  4. Have to locate myself at a place without any obstructions for good view, and
  5. Have to practice a lot for smooth tracking, pressing the shutter release without shaking the camera, to find appropriate shutter speeds to match the speed of the motion and my position relative to the path of the subject, etc.
PS: Some of my friends commented that they liked the 3rd photo above. I guess that they looked for the most sharp subject. But, panning photography is about getting a relatively sharp subject compared with that of the background, and little bit of blurring of the subject adds effects of speed, direction of motion, etc.

Standing tall at the heart of Bangkok, the Baiyoke Tower II is the most famous building amongst tourists and photographers to have a spectacular bird's eye view of the city and beyond up to the Gulf of Thailand as well as to enjoy a nice dine with music at the roof top restaurant. The building also holds title of the tallest building of Thailand, which is expected to be grabbed by Ocean One Tower of Pattaya by 2012.

Buying tips for a digital camera

Every now and then I receive emails and Facebook messages from my friends asking "can you suggest me a good camera?". Some are little more specific in their question - like "can you suggest me a good DSLR camera for traveling?". I guess, these queries are the results of my habit of adding photos to my Facebook albums, Flickr and Blogs very often.

My humble opinion is that these questions are very difficult to answer unless some basic details are provided. Furnishing the following details would be helpful for others to give some useful suggestions in the selecting a camera:
  • Your budget,

  • Area of interest in photography, e.g., family portraits, general portraits, events, travel, wildlife, sports, etc (If more than one, give a priority order),

  • Your knowledge and exposure with photography,

  • Brand and models in your mind, and

  • Reason for a new camera: E.g., upgrade, first-camera.
A question with lesser ambiguity always gets a better answer, and in this case some good suggestions.

Here are some tips that might be useful when buying a camera:
  1. Figure out your specific interests within photography and the technical features required to fulfill them.

  2. Select the right type of digital camera suiting your requirements and the models having the features of your interest. Also, think about future upgrade options, re-usability of lenses, short and long term costs involved, etc, if you are choosing a DSLR.

  3. Read the online reviews and compare them.

  4. If any of your friends have the same or similar model of your choice ask for his/her feedback on the camera, and if they allow, try few test shots. Otherwise try the camera(s) at a professional camera shop. It would be great if you can see your trial photos in full size on a PC monitor. Check whether the camera is handy, and you feel comfortable and confident with it.

  5. Decide one or two models and the accessories of your choice (extra batteries, memory of right capacity and speed, etc).

  6. Find a genuine shop offering a reasonable price for your selected digital camera, and check for warranty conditions. Compare the prices of items sold as individual items and as a bundle. Note that in some shops accessories are sold at unreasonably high prices as many buyers only compare the prices of cameras and do not pay much attention on prices of accessories. In some places a little bargain is necessary to bring down the prices. Let the sales person understand that you have some understanding about cameras and accessories, and have already done some study on prices.

  7. Once you buy the camera, do not forget to save your receipt, the camera's box, and any other documents related to warranty. And, do not forget to register your purchase with the manufacturer whenever required. It is also a good idea to scan the receipt and keep a soft copy as thermally printed receipts fadeout with time.
NB: Buying cameras and accessories online has got both pros and cons, and I have experienced both. So, I would neither recommend nor reject the idea of shopping in the grey market.

For those who are considering an upgrade, the following tips might be helpful:
  1.   Improve your knowledge on composition, full use of range of controls available on your existing camera, and post processing. And, then en-sharpen your skills through practice, practice, and some more practice. The statement - 'it’s the photographer who takes photo not the camera' - is true for a great extent.

  2.   May consider buying supporting devices, and other basic accessories that would take you few steps forward in photography (E.g., external flash, tripod)

  3. If you already own a DSLR and only have slow lenses, then upgrade your lenses to faster lenses, for example, a prime lens and/or f/2.8 zoom lens.

  4. If the above have reached a saturation point and you still look for some improvement, then go for the next level of camera like a full frame DSLR.
Manufacturers release new models every now and then. Unless we are into professional photography frequent upgrades are not necessary. I am using the same DSLR for the last 5+ years and am generally satisfied with the outcome.

Disclaimer: A person who plans to buy a camera should take the responsibility of putting some effort to search for information, to verify the suggestions, and to make the final decision.
