So I need to make some large prints for a wedding coming up. Nations looks like to have some canvas based prints with 16x20 and larger. Although at $97 for a 16x20 is quite up there imo, I guess I dont know where else to go that would have large prints. Any suggestions or if anyone knows about the quality of Nations Photo Lab?

I do not know about that lab, but I have never been disappointed with prints from West Coast Imaging. I have not printed anything from my 5D Mark II yet, but they have done drum and Creo scans from 4x5 & 6x7 film for me and the print quality has been nothing short of spectacular.

They also do color, having started in b&W:

Nothing about Nations Photo lab though eh? I havent really found anyone elsewhere that does something like that. Thanks for the help.

So I ended up ordering a 24x30 from them. Using a 300dps 12MP jpeg from my Canon 5D it came out very nice. Accurate color and good quality. I would not hesitate to use them again.

www.QualityCanvasPhotos.com for larger canvas prints

[Disclaimer. I have an association with this online site]

I do 16x20 RA4 prints on Fuji Crystal Archive Paper for 9.99 each matte, glossy or lustre finish. Other sizes are also available, 20x30 are $12.99 each.

They are not canvas, they are true silver halide prints made on Chromira 5x ProLab.

If your interested drop me a PM and I'll forward you ordering information.
