In some recent threads I've readed some people talking about ways and programs to resample/resize an image, aproximatly to 2x bigger than the original one, meaning that an image of 6MP will become 24MP (to duplicate size you need 4 times more megapixels).
I'm thinking os this becase one issue: when I'm doing or planning to do large prints something ocurred in my mind: If I'm printing for example 20x15 inc. prints, but you have a &MP image (3000x2000), what happens in the machine that is printing it? does it interpolate the image or does it decrerases the dpi rate to fill al the photo? Because with 3000x2000, at 300dpi you should only print 10x8 prints, withought decreasing dpi's.
So my thread has two purpouses:
1º) Should I trust the interpolation of the printing machine? Or instead should I resize/resample the image at 300dpi to the size of the print?
2º) Which programs are the best to do it, because some people prefer other programs than photoshop to do it?.
Than's in advance.

In general it's best to do your own resampling since you have control of the entire process.
This tutorial may help. It is written for PS but the basic idea can be applied to any editing software that has a resize option.
Another program is Genuine Fractals. Google would probably pull up some info on that.

| From my reading on different forums, Genuine Fractals is highly regarded for resampling/interpolations. |

I've been using ResizeIT and have found it efficient and easy to use, although it does put a strain on my older PC (1.2ghz) for processing overhead.
The evaluation download gives you 15 free uses, then it costs $25 to purchase.
I don't have the URL available where I am today, but you should find it using any search engine. Good luck. |

| At DPC Prints, for example, you can get good results at 150 dpi, so a combination of lower resolution and moderate upsampling should get you to some bigger-sized prints. |

Fred Miranda has a very highly-regarded Stair Interpolation action for photoshop on their site, it's under 20 dollars and reviews I have seen claim it works better than the much more expensive Genuine Fractals. I use it and have had great results from it.

They also have what's supposedly an even better one, "Resize Pro", but it needs to be purchased specifically for a particular camera model and they don't support my prosumer; it's for dSLR cams.

I checked them also (from your earlier mention somewhere) and their software isn't compatible with Paint Shop Pro. That's according to their tech contact.

If price is an issue for you:
Genuine Fractals 4.0 is $169
Genuine Fractals PrintPro 4.0 is $299 |

That seems pretty steep compared to $20 & $25 for two of the others mentioned in this thread. ;^)

| Big money to Genuine Fractals. But is it worth it? If one makes prints for sale it's probably worth it, but it's of the budget for me. |

According to reviews I have read, Fred Miranda's action produces BETTER results than Genuine Fractals. It's only for Photoshop, granted, but if you have PS I'm convinced it's the way to go. It works EXTREMELY well for me, and I'm printing from my Coolpix 5700 at approx 12x18 with terrific results. I can't go any larger with my printer, but I see no reason I'd have to stop there.
