Alex:
I had time to think about and execute 2 shots whilst the ferry was in the right place.
This exif for this is:
80-400mm @ 400mm
600mm (in 35mm film)
1/3200 sec, f/8
Mode: Av
Metering: Center-weighted average
ISO: 200
AF
mode: AF-S
White balance: SUNNY
Flash: OFF
Saturation: Normal
Sharpness: NONE
Contrast: Normal
after I shot this, I turned to multi segment metering and took a shot,
this time it wanted 1/1500 of a sec.
the shot you see here, was centre weighted and I metered off the water.
the multi segment shot taken a few seconds later looked nothing like this because it didnt know I was looking for the silhouette and tried to even out the whole scene.
I was happy with the colour of the water because I had seen photos with similar colour but had not actually seen it in real life before.
