Sorry, but photography is not a RISC OS strength. Photodesk is embarrassingly out-of-date, especially when held up against Adobe PhotoshopCS. For example, I can drop an image into PhotoshopCS and correct exposure with the click of a button. I can also have Photoshop analyse the colour levels and make automatic correction, which is just about always spot-on. Oh yeah, it's rendering is much sharper and therefore suited to commercial printing. Oh, then there's Web gallery creation, lense and filter imitation, high-quality special effects, plus all of the Web and print stuff.
