Are you sure its not "300dpi" for larger print sizes you saw?

Imagine ifyou resize a thumbnail of 120x160 300x you will end upin the Gigapixel range (36000x48000). The image quality will be of course unacceptable whatever method you choose unless you intend to print and pin this thing on a flat surface and view the image from a plane .

Yeah, ALOT help !!(in RIGHT hand)
especially good implementations of LancosZ3 (B-Spline and Mitchell / Kaiser and etc - not for common material) Algorythm's.
For Example - XnViewer/Nconverter - Free/Fast/Multiplatform tool, that can use free and bought ps extensions.
Try it :-)

and if you asks about CONSTANTLY upscaling by huge coeff - try Genuee Fractals, product of LuraWave, that bought it with maker - Iterated Systems and belong IP's)
or even some of JPEG2000 implementations(free - BETTER !!(both in terms of speed AND quality)). mostly - based on Kakadoo library. i prefer Gimp engine, because manageabulity and Adobe for same reason, but 4 free 4 win i recommend Fnord plugin(forgot realname autor-programmer :-/) - quite fast and accurate.

"compromise between bicubic and something ..." definitely not have enough resulting quality. even bicubic itself - obsolete for years.
but if someone found usual program[there at least 2 commercial and 4 free] - prepare for challenge you PC.
for example [x2 up]resizing of one 12kx8k image with Kaiser 64Tx4 recuires 2hrs on 3.0 Ghz dual-core CPU.

Stoik claims 1000% reizing with "Smart Resizer". A 15 day trial is free, the key costs $40 US. Sounds interesting, I may give it a try.

So much software around, hard to find time to try it out, and leave time for taking photos.

That sounds sort of like the restoration algorithm being used in some of the nicer Linux applications like digiKam (which is what I tend to use for most image processing anymore). It's extremely flexible for resizing, taking noise removal and more into consideration.

BTW, here's a good article on interpolation by Mike Chaney:

If you use Mike's QImage products, you can do a pretty nice job at resizing images (since it even takes printer drivers into consideration to determine the best settings to use).
