Friends,


First: I've been reading the community forums for months now and want to say thanks to all of you for so much help and good advice. I've learned a lot from you.


I've been invited to exhibit some of my photos at a small artisans' gallery, and I'm excited to do it, but I'm a little overwhelmed by the newness of preparing images for display. I'm going to use an online printing service and have the prints shipped to the gallery, so I really won't be able to see them before the show. Which is *very* tricky, I know, but it's the only option I seem to have.


I am shooting with a Rebel Xsi and the Canon 16-35L. Can anyone tell me how large I can blow up my images without losing sharpness and quality? I've never printed anything larger than an 8x10. Is 16x24 out of range for my camera and lens?


And any advice for a newbie?


Many thanks!


Gina
