hahaha no la... we all are learning, i am also noob

the DRO in A700 works a little diff with A900/850 and A550, seem like the A550 has much improved algorithm, the older algorithm usually brighten the whole photo rather then just the dark area, try shoot it with manual on tripod, DRO off and on.
well its because prehaps he is trying to brighten(overexpose) the photo so he able to see the faces, but the overexpose caused the overall photo to go brighter as well. (or out of the blue he used spot metering on the face (dark, so the Ai auto meter it to brighter) i mean, that photo, the faces are brighter~ then the rest...
Added on October 20, 2009, 5:56 pmand, external flash, how well does it works?
my experince,
1. u have to use manual, coz the stupiak A-mode will lock ur apperture(probably u gonna use F5.6 or F8 for group photo), and the flash will lock ur ss at 1/60 at wide, and 1/160 when zoom (bounce) or HSS 1/250 (zoomed/direct/SSS off)
and if the sunlight is strong, it actually required 1/640 at F8. the above 3 setting will Overexposeeee

alright then, let say use manual, u able to adjust F11, 1/160, when ur metering detect the surround is bright enough, the flash will auto adjust to fire at Minimum power. muahahahaha so, faillled again
so to actually have a nice photo at direct under the sun, u have to manual everything, set it right, only u get the real good result

a good trail for u guys who never shoot under direct sun (for fill in the face) go try it! good exp... fast go level up~
then the DRO is pretty weird than. (im not using alpha now)....i usually turn on the DRO (function) whenever im shooting outdoor esp during those situation when i have super bright sky. I will post a few pics with it on and off to see the diff it you wana see it

...all i can say is that its pretty cool function to have, at least i can keep my GND at home and get a so-so result (of course GND will give better result).......
well, i always recommend one to use M whenever u are using an external flash....
cut short the entire story, to use fill-in flash under sun light using a flash gun
1) set camera to M mode
2) set HSS to ON
3) use spot metering (for more accurate result)
4) set AEL to TOGGLE (easier than hold)
ok here comes the method:
1) Meter the background (the background should be relatively brighter than your foreground)
2) lock the exposure by pressing the AEL button
3) now focus on the subject (foreground) and set ur flash compensation to -1.0ev or more (personal preference

)
4) then shoot

Result - your subject should be properly exposed as well as ur background, besides, the -1.0 ev is to avoid super harsh flash and to create a more subtle pic (personal preference too)...sometimes is use up to -2.0ev....the above technique can be used for indoor dark env too...
just my 2 cents.....
