If this is an indoor photo, your main limitation will be the flash.
That camera has a maximum flash distance of 13 feet (if you are not using any zoom).
Less distance if you are using any zoom.
I suggest you not use any of the mode settings.
Just set the camera to Auto and go with that.
And get as close to the people as you can.
I have a Fuji Finepix S7000, but it's being fixed, and am now using my mother's Fuji Finepix S5200. I will be taking some wedding photos this weekend and am curious what setting is best for group shots? I always use the portrait setting for single or couples, but wonder what's best for groups of people? Anyone have any experience with this? Any help would be appreciated! Thanks!
