Re: Ruined 3rd tricolor gum print! Grrrr...

Thanks, Don (can you tell I am sitting here gnashing my teeth while doing a Blurb book on Haiti and trying to use every diversion that comes my way?) for not only looking but also commenting.

The photographs were taken mostly by my mom and my dad--the old ones--but on the Family of Origin page I have taken a lot of those, too, as I have intertwined the old with the new. You can tell the old ones because of the dust and mold. I also have photographs taken by my grandparents and the 25,000 ones I inherited range from about 1920's to 1970's, but mostly only to the 1950's. Somewhere in there my mom stopped taking Kodachromes and started taking color negative/prints. Much inferior product. Anyway, those four kids entangled with a snake (can you believe she allowed that and told them to smile?) are my oldest siblings in my family of 8.

Some of the images are SO Lartigue I can't believe it. One of my mother bending down in the garden, butt stuck up in the air. No wonder I'm warped.

What a charming gallery. I have been reading about using Photoshop to
salvage old photos, but this is a far more attractive way to revitalise
them. Who was the original photographer (reminiscent of JH Lartigue)?

You are right to cut down phthalo.  It is an incredibly concentrated
pigment.  However, I develop it longer if it is too strong and that seems

Flaking--your layer is too thick with not enough exposure, but also the
layers beneath have created more of a slippery surface for the final layer
to hang onto. Thus you could thin out the final layer and brush it on
carefully.  I might thin it with, let's say, 2 di: 1 gum/color. This will
make the layer faster because of the increased dichromate and thinner
but that may help you even more.

The thing about gum is it is never a done deal--scrape off the layer and
start again.

What is ironic is just as you are dealing with this as a problem, I am
encouraging it.  This latest series of gums I am doing is the least
photographic series I have ever done.  I am working with old family
photographs/glass slides that are wrecked and molded.  Thus the images
get much worse.

I am attempting them to look more like silkscreens.  Thus, I print two of
the same image at once, and one I leave photographic and then one I have
been scraping away areas of color and then printing other layers on top.
am REALLY loving it, but then again I won't have any idea of the reception
of the prints. People may not like them at all. But I am finding that I
putting the play back into gum printing and embracing mistakes.

At the risk of intense criticism, I am including the first image I did of
this series in both the non scraped and scraped form.  Be kind.  BTW all
dust and mold?  Like I said, that is imbedded in the glass slide image.
Slide is probably about 50 years old. And this slide is actually one of
ones that is in BETTER shape.

If you click on the link below you will come to the Family of Origin
and at the bottom left are the two images first in the row.


SO what I am saying to you is that the print that just flaked and looks
yukky, if you can't salvage it, scrape and print another layer on top, or
the VERY least do NOT throw it away. Keep it for later because you may
realize it is pretty interesting stuff.
