For this particular assignment, I went to Batu Hampar Recreational Park which is the location for the famous Serdang Fall in Kedah. This recreation park is just located approximate 15 km from the town of Selama. During my visit to this fall, there is a big warning sign telling me to leave the park immediately. The outrage of “Rat Urine disease” aka  Leptospirosis at several recreational park around Kedah had put this park at alarming state as well. However, deep inside me, I still have a strong determination to get a low shutter speed photography on that day. As a result, I brave myself to enter the park and try to avoid any direct contact to the water.

Some geographical information about this waterfall is as below to whoever that find my post interesting:
Location : Near Serdang at Kedah Darul Aman, Malaysia
GPS coordinate : N 05 11.92′ E100 34.93′

Gadgets that I brought for the assignment:
DSLR Camera with lens
Tripod (prefer steady tripod with proper ball head)
Shutter release

For most of the shoots, I set the camera on lowest ISO as possible (ISO 50) and to the smallest aperture on my 24-105 f/4L (f/22 for example). The purpose of my setting is to get as much details as possible with a smaller aperture while the lower ISO can further slow down my shutter. Some note on the low ISO is the quality of the photo will increase as it will reduce the quantity of noise on my photo.  Why it is called as low shutter photography? Why I choose “slow shutter” for photographing a waterfall? Do see their comparison below.

An obvious comparison of both of this photo. The photo above is shoot at a slow shutter (3.2 second f/22 ISO 50) while the other is shoot at a faster shutter (0.4 second f/22 ISO 5000). Note how I increase the shutter speed by increase the ISO from ISO 50 to ISO 5000. This is how ISO and Shutter Speed compensate for the exposure, when you increase the ISO, the shutter speed will increase to compensate for the amount of light that hit the sensor. The first photo which shoot with slower shutter show smooth water flow. This really gave me a calm and relaxing landscape sensation. Contrasty, second photo of faster shutter speed gave me the feeling of rushing, strength and power of water flowing from the top of the cliff. There is no right or wrong in photography technique from both of this picture but purely on individual preference and your idea of photography. Personally, I prefer a slower shutter speed more than a faster one. I like to be calm and relaxing.

Summary on The Exposure Triangle:

ISO speed: A measurement of how quickly your camera’s sensor absorbs light.
Shutter speed: A measurement of how long your camera’s shutter is open for when you take a shot.
Aperture: A measurement of how wide the lens’ iris open when you take a shot.

My subject is focused on the rocks and water stream.

Waterfall and some rocks. Still on slow shutter.

The last photo is a HDR (High Dynamic Range Imaging). Let me cover this next time. So stay tune for more photography tricks and tips from Billy. Enjoy guys and keep on shooting.

You mean photography-ing = photographing and HRD = HDR and aperture = iris of the lens, right?

Oh ya .. Thanks dude.

Not using any ND filters?

Billy Chan · December 28, 2010 at 10:39 am

I didn’t use any ND. I don’t have them yet.

You gotta have ND for this kinda shot man, otherwise it just blows highlights

Billy Chan · March 20, 2011 at 6:57 am
