[alt-photo] Re: applying PVA size

[Kerik]

I've just started using Gamblin PVA size this week. For the most part I
like the results, although it's a close second to gelatin for me. It's
much easier, quicker and healthier than dealing with gelatin and
formaldehyde for sure! I've found it's been a little more susceptible to
staining than gelatin. I'm using it for gum over palladium and it's only
been an issue in even toned, smooth areas and only occasionally. Not a
deal breaker and I'm sure I'll be able to work it out. I'm using it
diluted 1:1 on Artistico Extra White. I apply it with an acrylic coating
rod (similar to a Puddle Pusher but home-made and unbreakable) on prints
up to 17 inches square.

I'm preparing for Fotofest (Amy, I'll be in touch!) and this approach has
helped streamline my process.
