HDR..

Merged 3 photos to HDR:

Step 1:
i) Using Canon S3IS Set Dial to Program
ii) Press FUNC and choose AEB -> SET -> Exposure -2 0 +2
iii) Use a FIRM TRIPOD and aim your target (still target best).

UnderExposed (-2)
Normal (0)
OverExposed (+2)

Combine the photos

Either use Photomatix (http://www.hdrsoft.com) or photoshop CS 2 ( Only CS 2 has that function ) Depending on algorithm... U have to wait 5~30mins for it to process the image (took me 10mins PC)...

This isn't really that nice of a image... just randomly shoting out of my flat (20th floor) and i got the ISO setting too high + Haze (cough).

From what i read from the internet... ISO of lesser then 200 is best. Also u can only change exposure level by changing the shutter speed. If you change ISO or Aperture, the Depth of Field or ISO noise will cause problems to the image.. U can use 2 or more images, the more the merrier (provided it's still and on a tripod + exposure are at least 1 stop part).

for cheem cheem reading.. see reference below.. :P.. the quote above i got from some forum, forgot where.. my pictures are not good enough to display the HDR effect.. looks like i hv new hobby.. heh..
