If you had asked me a few weeks ago what the advantages of eight megapixels (MP) were over five, I would have said very few. However, that was before I discovered the fun factor in being able to play with an image that is up to 115cm by just over 86cm (72dpi).

Once upon a time not too long ago, your average inkjet printer had a single tricolour ink cartridge. Of course, the print quality was fairly ordinary, but it did the job. Today, with digital cameras the norm and home users wanting to print their own photographs, your photo printer may have as many as eight different ink cartridges.
