Increasing resolution on images

[dawesy]

Like a number of people on the forum I'm now making work available at Red Bubble. Unfortunately with my 6MP camera, prints can only be sold in the small size, which is 203*303 mm. I am tempted to increase the rez artificially to try and make the files available as medium or even large files (305*454 and 406*606)

They want long sides of 3240 for medium, and 3840 for large, comapred to the 3008 get out of cam.

So the actual question: will the quality still be good enough if I uprez to make decent prints? I guess the only sure way to know is to try it and buy one, but some advice would be appreciated.

Also what the best way to do it is, I have cs2 available and can get a hold of cs3.

Thanks.

I printed A3 from my Nikon D70 many times without any problems. Haven't tried larger sizes but it looks like it would be fine as at A3 all images were absolutely fine. But I still can suggest to print your images at local camera store at A3 or larger just for testing.

If you want to resize you need to use "Bicubic Smoother" in PhotoShop or third-party software like PhotoZoom or Genuine Fractals. From my experience there is no big difference between "Bicubic Smoother" or third-party apps if you upsizing up to 2 times (linear dimensions).
