JD, one of my friends posts many Lytro photos and I think the quality for viewing on the screen is great. for prints maybe not. But we are taking about helping us SELL and we all know how important photos are to this process!
with jewelry or any 3-d object unless you are using a profession set up it's difficult to get all aspects of the piece in focus. jewelry sell best in person when the buyer can touch it and see it up close. the Lytro photos would help with this
