I don't know if metering really help much in this scenario.Since I shoot with manual strobe, I am not sure if any particular metering scheme is any better than other with such extreme exposure range. I usually just kind of eyeball the situation a bit, take a couple of pictures, review the picture then adjust accordingly. Leave the shutterspeed at the fastest setting ( 1/250 in D2X case), then keep going on the f-stop and adjust strobe power accordingly.

I always use centre-weighted or even spot metering. Any evaluative metering system is effectively a form of automation as it takes into account a varied set of parameters. If you are shooting a fairly static image or can pre-meter, then take a shot to 'pre-meter' and then use the histogram to adjust exposure to as high a level as you feel possible (this will inevitably losse some suburst information) - the top 1 stop of information from a linear, digital exposure represents 50% of the information so any underexposure will affect shadows the most. Hope this is the sort of answer you were looking for.

Wanted to ask a quick update on sun balls

Are the tips and techniques still the same now that technology has moved on considerably. This is something that I would really like to try on an upcoming trip, currently have a d7000

Any help much appreciated

i use the lo ISO settings on my D90 and it seems to render them nicely - before at ISO 200 they were awful and i found it hard to meter and expose for on my D70. but the D90 is easy and i imagine that the D7000 will be even better : )

Any chance of the shutter/aperture you are using?

1/200 as it is as high as my D90 will go with the flash attached.

Here are some examples of unedited sunbursts with both the Nikon D90 and Nikon D7000 to give you an idea. Both setup used hardwired Ikelite DS161 strobes. The fastest the D90 can sync as stated before is 1/200th and the Nikon D7000 can sync at 1/320th. I think that with opitical tiggered strobes like Inon Z240s the fastest it can sync is 1/250th, but I am not 100% sure, someone with that setup can confirm.

There are other factors which need to be considered. Water clarity, Depth, position of the sun, surface conditions (ie waves or glass out conditions). Most successful sunbursts I have found personally is shooting shallow (ie less than 10m) on a clear bright day with the sun high and in clear still water but generally the position or location of your primary subject has alot to do with the final outcome.

Sometimes your subject isnt in the ideal position for a dramatic sunburst but using the sun to high light the subject can also be done. Here is an example of subject not being in the ideal position for a dramatic sunburst but the effect of the sun still gives an attractive highlight.

All shots posted are unedited to give you a more accurate idea.

Hope this helps.
