Printing developer on to the photograph paper

[Mustafa Umut Sarac]

Hello , I think if we expose a photograph paper with enlarger and print developer on to the photograph paper , we can A X B times more tonal variation.
As you know printers lose time to reach one corner of the paper to the other.
We can adjust the size and mass of the dots , first dot is the smallest , last dot is the biggest.
I think this is really hybrid and interesting idea.

Best ,
