Gidday Woody,
I use spot mostly, second choice is centre weighted. For me matrix is just not worth the time.
I have found that matrix really does not work that well outdoors in very bright conditions - I found that I often got blown backgrounds using matrix. Matrix also seems to be more centre weighted than what I would expect. Very bright areas at the extremities of the frame are totally missed. It all has to do with the location and number of sensors.
When using fill flash I usually spot meter (although centre weighted works equally well and allows for a little more error) from the brightest part of the background in manual
mode to set background exposure - usually .3 to .7 below what meter indicates to account for flash depending on how deep the background is - a close bright back ground needs a more negative compensation than a far bright background to avoid blown highlights from flash.
EL button is set to FV lock. Focus on subject, lock flash value, refocus and compose holding focus and fire away. The beauty is that usually I do not need to alter background exposure or flash value for subsequent shots unless composition changes substantially. Usually the flash is set to ttl (ttl-bl for centre weighted) and -1/3 EV.
All of the above sounds complicated, but once you have done it a couple of times you will find it simple and works like a charm. Don't forget to check the histogram.
Without fill flash I will use M
mode and spot, roam around the frame to check the background exposure then meter of the face of my subject. If my subject is going to underexpose I pull the SB800 out of my bag. If my subject is going to overexpose I will dial in the correct exposure and suffer a slightly darker background (which I prefer anyway).
BTW, I usually shoot M
mode, sometimes A indoors with flash, never S
mode, I do not know what P
mode does, and the rest are totally useless to me (never even tried). Matrix metering would be more useful if there were more sensors, but because there is not, I do not bother.
Cheers
