Thanks for providing a photo! I always enjoy seeing the photos.

But, as I am an amateur photographer I would have hoped for a better photograph. Maybe it is just me but it seems kind of fuzzy :(

I can recognize the people in the image, which is good.

Maybe the 1/80th of a second exposure time allowed the camera shake to occur.

May I suggest for the future a tripod or crank the ISO up on that sucker :) If the ISO had gone from ISO 100 to ISO 400, the shutter speed could have been 1/20th of a second, which likely would have helped.

But again, thanks for taking the photo in the first place!

It was a difficult photo environment; the group was crammed in tight and getting grumpy and the space was limited. It was an extreme wide-angle shot from the side, requiring more depth of field than I could summon in those conditions. Backlight didn't help. The pro had synced flash and such, hopefully he did better.

I was kind surprised that the photo was taken with everyone's back to the window. I can see it though, if the hired photographer was adding in strobes to match the ambient light from the window.

But if you are the photographer without the strobes, then you are kind of out of luck :( Best you can get are the people exposed properly and everything outside the window will be overexposed.

For those who might be interested in off-camera flash this is a very informative site:

Again I highly appreciate the photo and I am not trying to be negative. Just trying to give some ideas for future attempts.

It must have been hard to shoot, but I do like the bright sunlight coming from the right, making the faces half golden.

FTR, 1/20th of a second (50ms) is a longer exposure than 1/80th of a second (12.5ms), and thus more vulnerable to camera shake; I'm guessing you meant 1/320th of a second (just over 3ms), especially since both boosting the ISO four fold and increasing the exposure time four fold would tend to overexpose the photo.

Indoor shots with strong backlighting are tricky unless you're going for a silhouette effect; fill flash often helps balance the lighting.

Totally correct. I'm doing my math wrong over here :)
