Just Posted: Our preview sample gallery from the Canon PowerShot S90. We've just got hold of a production version of this latest photographers' compact, so, given the apparent level of interest, have put together a preview samples gallery. Canon made a big play of its 'high sensitivity' 10 megapixel sensor so we've made sure we've tried it at a range of ISO settings, and have included a couple of low-light portraits under challenging tungsten lighting.
