Dear Ron:

Thank you for your review on the flower sample.

I think that the problem fo the double images comes mainly from the
focus when processing and the focal length when shooting such as I said
in the posting before. When the major object which is focus on when
processing and the focal length is right when shooting, it is clear. In
the flower sample, the focus when processing is on the basket, the
basket is clear. the two flowers near it are relatively clear(little
double images). However, the leaf behind them is blurred(double images).
I once asked the computer specialists how to solve this problem. And not
all barrier photos have this problem. I would like to mail you another
"diamond" sample. You could check if it is better solved for the
double-images problem. Then you could mail both the samples back to me.

Moreover, I still insist my opinion: a new product might present a new
trend and could beat the older one even if the new one has some weakness
at its begining, such as Microsoft and Intl beat IBM. 

Sincerely,

Jason Shen
