Dear Chic:

Why don't you do want the advertisers use? They take the Color Photograph and use a Ink Jet Drum Plotter say a HP Design Jet 750. An "E" size drawing is 34" by 44". Most HP Design Jets can print 36" by 48" at up to 600 dpi. That's up to 21,600 pixels by 28,800 pixels. Using a dithered 16x16 cells you can get 1,350 by 1,800 true color pixels. This should do for most photographs scanned by a HQ scanner say a HP 6250 or equivalent.

I have an old customer who uses a HP DesignJet 350 E size plotter. It only does 300 dpi but will give you a great looking image on glossy coated paper.

I use a Leica M2 on 35mm and it consistently gets well over 6,000 pixels by 8,000 pixels on ASA 64 Kodak Etkachrome Film. I used this to make slides of landscapes when I used to go on summer vacations. I have good shots of Yellowstone, Grand Tetons, Grand Canyon, Yosemite, and other NP and points of interest. There are many high quality film scanners that will do the photograph justice. Given such a HQ slide, Blowups to 3x4 feets are easy for a shop that has the equipment. The Ink Jet Drum Plotter is how the advertisers take a photograph and generate a 20 foot by 50 foot Billboard sized picture.
