I am sure this has been asked before, but wanted to know the latest information on the good Photo lab anywhere in US who make large prints approx size of 20 X 60 with maximum DPI.
Some of the labs i have spoken recently said that they will print only 150 DPI at that size instead of 300 DPI. I have my first few 6 X 17 Fuji Velvia 50 Slides that has been Scanned at maximum DPI on my Flatbed scanner and wanted to print few 15 x 45 or 20 x60 for my home and was not able to find a good lab.
I will be happy if there is any place near DC but willing to send the Digital file to any lab.
Also, What is the best DPI for printing such a large print with out loosing the detail. Attached is the sample picture i would like print which is been re sized for upload purpose.
Any recommondations are greatly helpful.
