    Default Dawn at Lim Chu Kang Jetty

    Shot on Velvia and "scanned in" using my G2.

    These 2 were taken with my AFS 17-35/2.8 wide open so there are slight fall offs at the edges. Not as noticable on slides but more prominent digitized...

    the 'scan' quality of the last picture on the 2nd post seems a lot better than the rest, which are kinda soft.

    btw what actually is fall-off?

    yeppie99: oh, its suppose to be "light fall offs at the edges", meaning the edges are darker then center portion. The softness is most probably due to jpg compression (and I didn't really apply very strong USM).

    Goose: nope didn't write down the exposure value, but I was using aperture priority mode, and the 1st 2 pics were taken on the AFS 17-35 with f/2.8 due to very low light condition, the rest were taken later using aperture around f/5.6.

    what causes this light fall off at the edges?

    Why did these two pix look as if there's a blue/purple filter across your lens? Did you edited it or there really is a filter over your lens?

    Because the original slides do look purplish-blue. I took the pictures without any filters. Brought along 81A and cir-pol but decided not to use them.

    I'm not too sure about the technical details, but generally it's caused by the design of the optics and/or slight lost of light due to narrow lens barrel. Fall offs are very common on super wide angle lenses where lots of glasses are used to correct the linear distortions. As a matter of fact the AFS 17-35/2.8 has done extremely well in that once it is stopped down to f/4, the fall offs are gone.

    Or it is a feature of Velvia film? :P Anyone can confirm anything on this? :P

    I like these shots. Nice serene feeling.

    I thought the Jetty was locked by a gate nowadays?
    The beach seems to be "cleaned" too

    Oh... I was using Velvia so it's ISO 50, but due to the low available light I decided to "rate it at ISO 100", meaning I manually set the camera to ISO 100. The camera will treat the film as an ISO 100 film, and when developping it I'll need to tell the shop "Velvia push 1 stop". The draw back is that the cost will be about 50% higher, and it will have more grains.
