Michael, adresaba and Johnmcd, thanks for kind words. Still learning and having fun at the same time.
varchs, the best article i have read on split grade printing is here:
http://www.lesmcleanphotography.com/articles.php?page=full&article=21
but i have read all the stuff and watched all the youtube video but nothing comes near to explaining split grade from the Lynda paid videos:
http://www.lynda.com/Photography-Bl...te-Darkroom-Printing-Techniques/372526-2.html
after watching the topic on "split filter test print" i felt confident enought to go do it.
it is not free but worth the small investment to learn it.
in my opinion, the advances in BW darkroom printing in the last few decades are:
* splilt grade print
* f-stop printing
* enlarger metering
while these topics are not required to make a good print, it is nevertheless something interesting to learn and tinker, especially now that the equipment are quite affordable.
