Thanks for the intelligence David


Yet from what I see, the comparisons are outdated; L3 beta is long gone, we at 
LR5 or CC6 now - my copy of LR 5 works better than the previous ones even 
though the changes in the sliders/controls make it difficult for regulars such 
as me to adapt.

 HI Bill!

Every raw converter I've ever seen, uses an algorithm to demosaic (or convert)
the raw image to JPEG or TIFF.  But, just one.

Interestingly,  RawTherapee has a choice of 8 different algorithms, so you can
pick the one best suited to your camera or photo style.  (Two are dedicated to
High ISO images.)

For those interested, a comparison of various methods (with examples) can be
found here:

Another page compares the DCB algorithm to others, including Silkypix, DXO,
Bibble and Lightroom's algorithms - among numerous others.   Again, with a very
effective, interactive image which shows the differences, quite clearly. Found
here:

http://www.linuxphoto.org/html/test_demosaicing.html

This and 109 pages of instructions (pdf), are keeping me busy!

The current release (v4.0.01)is a "development build", and is fairly, but not
totally stable.  Needs adequate memory. But, for what it does, at the price, I
can live with it's foibles.  It's open-source, and the team is working towards
a completely stable release.  (For those who don't wish the troubles, the
previous, very stable release, 3.0, is still available.)

Cheers!
David.
