Hi All,
I have an image that I need to scale up - it is starting out at 512x512 pixels. I understand that there are tools out there that will do a much better job that a Photoshop bicubic resample, (Extensis? Real Fractals?).

Assuming it doesn't break any license agreements, would someone with such a tool be prepared to upsample it to 2000x1000 for me?

TIA,
Nick

I'm not sure that by starting with that small of an image you'd really be benefitting from using something like Genuine Fractals. Those programs are more intended to take a hires image and make it look well when it prints abnormally larger, like 8x10 photo to side of a building.

You could try but I think I've had worse results than with Photoshop starting with small images.

Could be a case of re-rendering nick or increasing your res in ps then handtouching.

You could also try putting your image through a program that would turn your image into a vector illustration and manipulate from there.

I'll give it a go if you wish?

What kind of an image is it? Can we see it? Some types of images will upscale really well and some won't.

Thanks for all the responses guys - it is actually related to another query elsewhere. I am trying to make a bump map for the Moon derived from a normal map. I found a prog that helps, but it is only producing 512x512 images.

The good news is that I have been invited to join the beta, and the new version is more flexible in output size.

(To be more specific, it is actually a height field that I most want to recreate, though these can be considered the same in this case).

Starbase - I have Genuine Fractals and if you ever want to test it out let me know and I can run your image through it. I wouldn't really recommend going over 200% though, but it does depend on your final use as pointed out.

is it a vector or raster image?

It's raster thanks, but I think I need to work out a better way...

hmm yeah, raster images can get blurry or hard to see when you start scaling them. i've jsut tried scaling a 1440x2067 JPG image up by 300% to check as i've never had to do it before and was seeing how it looks, and it looks pretty good even after the scale, I think the main problem is when you try shrinking the images too small.
