Overall image quality is best summed up as being OK but not particularly outstanding.
We did find that greens can look a little oversaturated and unlifelike.
Blue skies also lack the subtle variations in tonality that better cameras would be able to capture.
Image sharpness isn't too bad though - especially given the XP150's folded-lens design.
It's possible to use the XP150 underwater up to a depth of 10 metres.
