Re: gum on wood panel
I don't know much about Nikon lenses but probably it's a very fine piece of glass... Paper-like behaviour: I think it's a matter of fine tuning the whitening / glue ratio. Unfortunately there are numerous traditional gesso recipes circulating in the web; it seems that I will have to find the correct amounts myself, after some testing... And it's not easy to test because preparation of wood panel takes considerable time (4 or more layers, waiting the layers to dry, sanding...) :( Greetings to all of you, Loris. 18 Şubat 2009, Çarşamba, 12:47 am tarihinde, Keith Gerling yazmış: > Hi Loris and Elif! > > Yes, its a recent shot from my Dancer series - taken about a month ago > with my newly-acquired Nikkor 105 f4 Macro, which I love.
