I used t have a program that would take a diital pic and enlargeit to any size I wanted. It would then crop the pic to make any shape I wanted. It would then divide the pic up to letter size sections and print them out on my inkjet printer. I could paste them together and have a nice color photo. It worked great.
When I got a new computer the program was lost.
DOES ANYONE KNOW WHAT I AM TALKING ABOUT AND KNOW WHERE I CAN DOWN LOAD THE PROGRAM???
Maybe here, Art?

You can stitch multiple shots together in Photoshop. The process is not that hard and you can obtain great results with a digital SLR and raw files. JPEG will also work and the file size is more manageable.
When you have finished the manipulations, the best results are taking the file to a professional printer and have them do it… I am concerned that if you piece meal a number of 8 x 10s together, it will look like unrelated photos taped together and not give you the results you seek.
Depending on some variables, you could accomplish a 10 foot wide back drop with excellent clarity. Google Mike Confalone. He has been published in MRR and most recently, other publications. He is very good at what you want to do.
I don’t know which program you are talking about either. Is your new computer a PC or a Mac? That would be the first basic question I would have. Through the years, there have been several good but basic programs included with PCs; I don’t know which one you might have had. This also varies from different computer vendors as to what is pre-loaded onto your system.
As others have suggested, I’d consider taking the photos to create the backdrop you want then stitching them together in a program like Photoshop or Paint Shop Pro. Didn’t know this till recently but there’s a site called Old Version http://www.oldversion.com/ where you can apparently download older versions of current software. I know that several older versions of Paint Shop Pro are there; PSP is my program of choice for photo editing.
If you do reshoot your photos, keep in mind that a tripod is almost mandatory. Otherwise, they won’t be nice, straight & level. Make sure that your camera is in Manual mode and that anything automatic is OFF. Otherwise, each shot is recalculated individually by the camera and there will be noticeable differences from picture to picture.
Take plenty of overlapping pictures. I’d shoot planning on only using the middle third of each image when I stitched them together. If you must move the camera as in taking a row of storefronts in a downtown area, try to maintain the same distance from camera to subject and don’t touch the zoom lens. Keeping the photos all the same will make it much easier to assemble the final image or images. Use plenty of Feather when copying & pasting; this will avoid harsh lines between the individual photos.

I use an older program called Poster 7; I haven’t been able to find it lately but there are other free sites around that will do the same thing. You put your picture or collection of pics into the program, tell it the space you have to cover, & it does the rest for you, outputting it as a whole bunch of overlapping 8.5" x 11" pics or as a banner file which you can get printed at a commercial printer.
Contrary to some other proffered advice here, the ‘mosaic’ technique can produce quite a nice effect (although I don’t use glossy stock anymore!)
