Blowing up pictures to poster size

[Sti_Guy]

Just a FYI, If you have a Sams club around your area they often have a photo center that do posters up to 24x36. I have done a couple myself with my D50/D80 that have turned out great. Best thing is they are only like 22$

I think there are settings on your camera that may bump it up to a higher resolution when taking pictures?? I have that option on camera.
The reason I know about the high res stuff is, I used to work in a print shop, so I exactly what you need. Scott is right. Printers like to use a 300dpi resolution picture. The higher the better. If is a small picture, the resolution doesn't matter too much. It depends on the final size though.
GOOD LUCK!!

Thanks!

I talked to a printer in the city and got quoted $210 for a 48" by 72" C-print with UV protection. They also said 150dpi would work...which doesn't make sense based on our conversation. Not something I want to test, so I might just use the SLR pictures at higher resolution and go for 60" by 90".

You can also get it printed on a canvas type material. Looks like a oil painting sort of, check that out. It's fancy art word name is a giclee, or something like that. It's great for art for your house.
