6 foot by 6 foot photographs on concrete.
I have worked a project of this kind for a fee !
If you want full colour you are being over ambitious unless you are prepared to
put down a colour print that size and put a transparent cover on it.
If you want a single colour you can put down a ground but what that consists of
will depend on the colour you want and the colour of the concrete. Gelatine and
pumice powder, or PVA are two means that come to mind.
You will need a very large negative, the size of your final image, which can be
got from exhibition display houses.
You could then use gum bichromate, any colour, applying it with a yard brush or
cyanotype, blue, where the solution will need to be applied with a large
wall-paper hanger's brush. These two processes have the advantage that all you
need to develop them is water.
Unless this is in full sunlight you will need to borrow a very powerful UV lamp,
1500 w, and your exposures could be as long as eight hours.
Obviously you will need to do tests first.
This is not going to be cheap. Is somebody prepared to pay quite a lot of money.
It will work if you have the money and the time.
