Subject: [Leica] IMG: Yosemite too... and Raw exposure for

Been gone for a few days so I have not had the opportunity to view mail.
When I open up my PSD file and look at the levels there is no clipping in
either the blacks or the whites.  Perhaps I need to try another JPEG save
with better settings. 

I admit this is my first time at trying CD3's HDR option, or any image
combination for that matter.  Do not use my example as a good example.  I am
going to attempt more of this in the future and will learn more as I go

Thanks for the comments and interest in my attempts.  I will try some more
or some different settings.
