Hi Iván,

Again, very nice images.  Congratulation.

This is very understandable.  

I also used to aim for the look of the slides when I process the images.
Even now I still wish to achieve this but practically I just give up.  Comparing
to my processed images on the monitor, the original slides are softer.
However, despite the low contrast on the slides, it is still very easy to see
the details in the highligh and in the shadow.  This is very difficult
for digital
images on the monitor.  If I make the image contrast on the monitor as low
as that on the slide, the faint nebulas and highlight details will
just fade away.
I believe this is because the color depth and dynamical range of monitors are 
much smaller than those of slides.

Now I tend to think that digitized images on the monitors and images on the 
slides are two different worlds.  I give up making them alike.  

Cheers,
Wei-Hao
