Hi Matthew,
Thanks for sharing! Nice
work, do you start out with a “full” pt/pd print (ie a print which is
“finished” ) or a little light?
Do you use the same negative
for the gum print?
I guess that my print is
better labeled platinum and gum, since I first print a high contrast image with
platinum (missing most of the mid tones and no high values), and than with a
low density negative fill in mid and high with gum.
I did do some gum over
platinum and I agree it is a realy nice way to enhance an image.
Last night I made another
gum and platinum print last night, this time I mixed some yellow in with the
burnt sienna and took a deeper black Pt print.
If I have time I will
upload that image tonight
Best,
Cor

I've been doing gum over platinum/palladium prints for a good long
while now (relatively speaking of course). Clay Harmon graciously spent a
weekend giving me a crash course in it and I've been stumbling my way through
it for the last few years.
Its a wonderfully addictive process, as I've heard many practitioners
state, gum layers atop a pt/pd print can do nothing but improve a print. :)
I usually print either 2 or 3 layers of gum. Have found fabriano
artistico extra white to be the mainstay paper, prebath in oxalic acid, sized
with formalin after the pt/pd print is done. Using winsor&newton wc
pigments. Good combo for my working methods.
Enjoyed hearing about your process etc.
Hope to see more of your gum overs.
1- indian yellow and burnt umber
2- burnt sienna, perylene maroon, and burnt umber
3- black (short exposure helps punch the shadows a bit.

Since the
list is in a image sharing mode (which is great, I love to see the work of
others!) I would like to share a first result (it is still work in progress) of
my regretfully infrequent alt printing adventures:
You can find it at: http://home.casema.nl/cordieuwke/GumOverPlatinum.html
The details, for those interested:
I started out with a Kodak Infrared negative (35mm). It was made during our
trip in May to Turkey. This one is from the wonderfull area of Cappadocia, near
the town Neveshir (Judy: the girl running towards me on the image is my
daughter, one of the twins..).
I made enlarged negatives from it by revearsal a la Liam Lawless (I still work
completely analogue..perhaps I am as we say in dutch "De laatste der
Mohikanen"..leave the translation to you..;-).... I made several negatives
with different Dmax densities by altering the flash time.
My idea was to print a high contrast image with platinum, and than fill in with
gum to lower the contrast and to add colour (with a low contrast negative).
The paper I used is Canson Fonteney, smooth side, pre-shrunk but not sized (I
hate sizing, and I know that this paper can take a few gum layers without
staining).
Only one gum coat is there: a weak Burnt Sienna.
And know I have to think what next, keep it as such, or add some other colour
(I am primairly a B&W person, scored a meager 37 on the colour IQ
test..;-)..)
Still have a few high contrast PT prints that need filling in, I am
thinking about yellow..
Best,
Cor
