Darkroom cookbook third edition

[Angelo di Mango]

Hi!
I am the happy owner of the second edition which I have greatly used, and I was wondering if the third one was a necessary and valuable investment... Has anyone compared the two?
Thanks for your answers.

The third is a big improvement, many formulae have been corrected, new sections added, people like Sandy King, :es McLean, Patrick "Gadget" Gainer and others have written short pieces. Definitely worth buying.
