A3 sized printes
We often say that higher resolutions come handy when larger prints are needed. So we picked a commonly used size to see how these images compare.
We decided to use the 40×30 cm size that is close to the standard A3 size. Most of the labs can handle this size without problem.
To make a 42 cm wide print at 300 dpi (common resolution of minilabs) we need a 4960 pixel wide image (42/2,54×300). This image, if we keep the 4:3 ratio will have a height of 3720 pixel. This gives a 18 megapixel image, so we will enlarge all our images to this size.
There are several algorithms available to interpolate an image. We selected Irfan View's Resample method to make the enlargements.

Due to the larger resolution, noise appears smaller on high resolution images. While these show up as large dots on G1/G2 images, they are only tiny, less distracting pixels on G9/G10 photos.
It seems that at A3 sized prints, larger resolutions have a clear advantage.
