Dear friends,
I knew of many of the participant today, that they were in a hurry,
hence, I was running through the slides in an unusual high pace; I
believe I was reaching about 1 Rubbia (big thumbs up is that is
understood ... let me know!).
Anyway, since it was rather a lot in a rather short time, below is the
text of the practical part of the HDR presentation.
For those who did not stay to the end, we decided that the next Meet 'n
Shoot (4th Tuesday of the Months) will be about HDR. So, please bring a
camera and your notebook computer with LuminanceHDR (or any other kind
of HDR software installed).
Kind regards,
Joachim

Take care to not drown shadows
Save image as TIFF
POST PROCESSING
Pull down highlights
Push up shadows
Increase whites close to clipping
Decrease blacks to your likings
Curves
Watch histogram for clipping
Increase clarity (local/micro contrast)
Increase vibrance
Decrease saturation!
