anyone uses Olympus TG 850 ?

[harlequin01]

hi i just bought this camera on ebay but it was difficult to take sharp underwater coral pics under LED even after adjusting the white balance. All came out dull and wash out. What makes it weird is my friend who has TG-4 (higher model) showed me how he took his pic. I uses his exact setting but still my display cannot show natural color like his olympus. i was thinking that mine might be defective. btw i bought mine refurbished. If anyone of you have the same camera please share your experience. thank you
