Goniochromatypes

Anybody in the know?
I havn't found anything about it in here - I know it and could tell about it, but if it is already here, there's no point...

I have heard the term but no idea what it is. Why not give us some background info and share some images?

I tried one about a year ago just to see how it looks/worked. Coated FOMA liquid emulsion onto glass and exposed it getting a silver print on the glass. Then painted iridescent paint onto the back of the glass. You have to put more than one coat of the paint on the back to get the full effect on the image. When you look at the image from different angles, the paint changes reflectance and color somewhat. Interesting effect, but kind of gimicky in my opinion. Not sure where I have the image - I'll try to find it.

almost right (or I misunderstood).

Apply liquid emulsion on glass and then make a B/W image on it. The image has to be printed in reverse.
After drying mother of pearl is then put DIRECTLY on top of the image. One layer would be enough.
The reason for this is, if not - if paint is on the back of the glass, the final image will look unsharp, due to the distance from image to paint.

This is the "classic" method.
I have "developed" it a bit, so I use two pieces of glass - one for the image and one for the backing colour. Which makes it possible to make multi coloured Goniochromatypes.
Very addictive!

Looks interesting. It is quite similar to orotones - instead of copper, brass etc you are using this "mother of pearl" (what is it, some kind of paint?)

Thanks for sharing.

That looks really beautiful, OP. I'd love to see one in person to see the iridescence of the mother of pearl. I was also wondering if it comes as paint, powder...I see there's an iridescent medium that can be used with paint...
I had never heard of goniochromatypes until now. Thanks for sharing!

it is - a water based paint - some iridecent - some not

a water based paint - quite thick so I delute it a bit with water

The process I used was based on a youtube video I found. The person who did the video put the paint on the back of the glass, not on the front and the silver print was not done in reverse. Yes, there is the thickness of the glass that makes the paint image different from the silver print, but that was what the video showed. Perhaps both methods are/were used back in the "old days". From your description, it sounds like your silver image ends up on the back of the glass, not on the front - am i following this right?

that is right.

some Goniochromatypes if of interest..
