![]() ![]() Also have a print made at 9.8x13 (or whatever it works out to on an 11x14 print) - that will be a good print with no interpolation. Have a full size print made of the entire image so you can hang it on the wall and evalute the print as a whole. ![]() I prefer to have an entire print made when doing this - some people have only a portion printed to "save money" - but that won't tell you the overall effect of enlarging the image to that size. Have them print it at the size you've stated. ![]() The best thing you can do is testing - which is as simple as sending file to the lab with a photo that has lot of detail and texture in it. The bicubic routines found in PS are the least sophisticated you can use and don't come close to the software in the Lambda, RIP software (inkjet printer), or something as relatively inexpensive as Qimage (inkjet printer). Don't try to "help it" by upsampling in Photoshop. Just give the lab the file, and the machine will do the rest. If you're having the file printed on a Durst Lambda, the printer has a built-in upsampling algorithm that is far better than you trying to do it in Photoshop or any other upsampling program. ![]() Which way do you suggest me ? Which max enlargement can I obtain by my d90, printed at 300 or 254 dpi without loosing definition and quality, and which enlarging software do you suggest ? Thank you, Marco. Photoshop offers bicubic interpolation, and I know there are several enlarging algorithm plugins as genuine fractals. The second way is to take one good picture and upsampling it. Even worse, at the end of stitching process, the resulting image will be wrapped anyway, and I hate this effect, expecialy in architectures. But I don't like this way, because of the need of a panoramic tripod head. So, this is the question : to obtain a large file to be printed to 40x25 inches at 300 dpi, I could take panoramic multi-pictures and stitch them by pano software. I' m not intended to buy a 24 mpxls camera as the d3x, too way out of my budget. I have a nikon d90 12mpixls camera and good primes. The printing lab has a durst lambda 300 dpi printer. I would like to make large prints ( 70x100 cm 40x25 inches). ![]()
