Extensis Smartscale or Genuine Fractals



Genuine Fractals

Smartscale is less hassle to use than Genuine Fractals

Okay, if these applications can increase the size of an image without losing quality, can I therefore get a 2mp image up to a large enough size to print on A3?

If that is the case, why are we spending 00's on 5+ mega-pixel cameras?

Because native resolution is always better than ressing up, that's why! Smile

There's a website dedicated to discussing this entire topic;
with comments and discussion forums about the various enlargement software.

These products use "interpolation" which analyses the surrounding pixels in an image and makes an intelligent guess as to what colour pixel should go there. In effect, they add information which wasn't in the original image.

You can res-up images in Photoshop or similar also, but this is best done in increments as it makes the interpolation better.

I've used Genuine Fractals and found it to be quite good, but it gets better as the source files get larger.

I've just found an app which sells for $19, so I'm going to download and try it tonight. I'll post details if it is any good.

Kneson Imaginer costs around 10. I have had it for a couple of weeks now and, although I have not yet had any results printed, it looks pretty good. I conducted the following test:

- enlarge a shot (my church candle) to 300dpi and 11" by 8".

- save it as a jpeg

- open this and the original in IrfanView and fit both to screen.

The interpolated file is noticable smoother on screen than the original.

For 10 you can't really lose.
