Ya. 10 mm for mountains is asking for it.. Too much space with nothing to fill it up. Maybe in cliff and plateau still can.Originally Posted by Leong23

Luo hei and eat until wanna puke liao... Don't care liao, eat finish go BBB then go off liao... So sleepy...
Today is my 1st luo hei of the year...Originally Posted by Leong23
ND filters extend exposure, idea is usually to smooth out water. Water at 30 seconds versus water at 1/500 seconds is very different, in the former motion is blurred and only immobile objects (like rocks) will remain sharp; in the latter, motion is captured, you will get wave texture.
GND filters have a line across the filter where everything above is darkened. There are 3 types of GND filters - hard, soft and reverse. Hard filters have a hard/sharp transition between the darkened area; soft filters have soft... Hard filters are better for shots where the horizon is very clear, for example, salt flats where you have a clear cut off part where you want the exposure cut down. Soft filters are good for shots where you have reflections, or for things like cityscapes. Generally in Singapore, soft filters will be more useful. Reverse are for cases where you have the brightest part of the sky at the horizon, e.g. just after sunset. For reverse, above the "line" is the darkest and then it gets progressively lighter. You can google to see the difference.
Hard versus soft
Reverse more expensive, need to get at least Hi-tech, Singh Ray also have:
On polarizers, this is a good read: http://www.cs.mtu.edu/~shene/DigiCam...polarizer.html
CPL can also be used like a ND filter.
Do note the inherent problem of uneven polarization with CPL use on UWA: http://www.earthboundlight.com/photo...arization.html

Yawns just woke up...Hangover argh.
