Night phototaking practice - 16 Apr 2016

Long exposure for light trails

-  set 2 sec delay to ensure no shaking at all
-  set smallest aperture e.g. F22
-  lowest ISO e.g. ISO 100 (if 200, shorter the exposure time by, say, half)
-  shutter speed at ca. 12 sec
-  if ISO is 200, try shutter speed, say, at 6 sec
-  it will capture the light trails of cars and the entire image is clear (beco of small aperture)


拉爆

-  same above setting
-  try rotating from inside out the focal length, steadily
-  or try counting to half of exposure time, then rotate the focal length
-  if shutter speed is 13 sec, starting rotating from 8th sec on, steadily
-  or try rotating from reverse direction resulting in different directions of rays radiating out


Multiple Exposure

-  may try double exposure, with one in focus, the 2nd out of focus


How to shoot light reflections at sea, ocean, etc

-  try iso 100, aperture f8, shutter speed from 10 on

-  longer shutter speed e.g. at 20 sec on will create a froggy, silky feel of the moving water

-  a big rock in front creates a perfect foreground

-  however, the rock is very dark

-  up shutter speed to, say, 20 sec and use a dark card

-  use of a dark card, and flash it in front of camera, continuously, during exposure will block the excessive light comes in, and increase the exposure time on the rock

-  rock will receive some light exposure as a consequence and the light  exposure on the image is balanced

-  try a different WB to achieve a "bluer" sky.

-  try ACTIVE D LIGHTING too in balancing the exposure between two different light contrast
