Red, cyan, van dyke, etc etc.....

Is there something like Cyan and Van Dyke process, that gives a fairly red cast.?
My search (supposedly just this forum) only turned up Filters and Safe-Light kinds of answers.
Thank You

VB will be dark chocolate brown once dry.
Cyanotype can have brown tones stained in black and green tea and coffee. ...depends a lot on how its done.
Haven't noticed seeing any thing red in alternative process, just various pale pinkish tones or brownish.

Not using altrenative process.
You could try copper toners, they can be red with the right paper, apparently.
I have never managed to get a good tone using RC paper. Always comes out pinkish.
Thats using fotospeed pallet toner.

Berg Brown/Copper Toner gives me the ability to choose among a nice range of browns and coppers on the Ilford and Oriental RC papers I use.

Gum Bichromate will give you any color you want!

Is that a fairly "easy" process, like Cyan or VanDyke.?
Thanks

Yes and no. It’s easy to do. Just mix gum Arabic, potassium or ammonium dichromate and pigment (usually water colors), then coat, dry, expose with UV light, and wash in water. However, it’s extremely finicky, and requires extreme precision to do consistently good prints. Also, they won’t have the resolution or dynamic range of Van Dyke or cyanotype. At least not with a single exposure.

There are other, similar prints that operate like that with adding your own pigments like tempra print and casein print. They’re no easier to do though. There’s also the carbon transfer which can be done in color. That one looks the best, but is extremely difficult to do.

Gum prints have some nice reds. Must try next.

Thank You.....i will look for some Youtube tutorials.
I have seen Bob Carnie discuss it in some of his videos, but i do not think it was so much of a "How To", as it was an introduction to all the different printing techniques his business employs.
Anyway, i will investigate further, and take another look at Bob's Videos also.
Thanks Again

Carbons also can be any color -- just not in the quick&easy category, though!

Robert Hunt's Chromotype/Chromatype will give red colors. Image is made up of silver chromate. It is process that uses silver nitrate and dichromate salts on paper.

Cuprotype is also another option. It uses some of the cyanotype chemistry.

Using red pigments with gum, casein and carbon processes will work too.

IME it is an easy process to get started with messing around and getting some fun results. Like anything there is a learning curve if you want to get good at it. The nice thing about gum is you can keep adding layers so you get more than one chance to get it right. If you dig through Bob Carnie's videos there are few where he goes through the whole process. Christina Anderson's book is really great, very clear and easy to follow.

This is a great thread with some info including my first attempts: https://www.photrio.com/forum/threads/multiple-layer-gum-printing.148200/

Also Uranotypes give gorgeous red colors if you don't mind sourcing and working with radioactive material.

Thank You.....Really Appreciate The Info

Thank You -
I am enrolled at my Local College in an "Alternative Process" class.
I am way behind for my Mid-Term, and need to pick a process (or two) and get going. I have very little artistic talent.....kind of a Fish Out Of Water in this class, as opposed to my (film) B%W Photo Class.

Is it cool to post a link to my teachers website.?

I have a lot of respect for her Education, and (probably) more importantly, her teaching abilities.
I am sure there are A LOT of people in All Fields that have had great teachers that "changed their lives".

Anyway.......Thanks again for all the great info.
I Really Appreciate It

 

[MattKing]

That looks to be an inspiring class.
Hope you are both thoroughly challenged and inspired by it.
Being around creative people is both exciting and at least slightly intimidating.
