Hello Artur. These days I've been doing some testing with this process, but I have a problem. The image always appears very soft, almost can not be seen. I am exposing the negative to the sun because I do not have a UV lamp. Should I leave it more time in the sun or should I increase the concentration of bichromate in the mixture? Thank you.
This process has very little tonal range. So first you need to specially prepare the negative, and to print at least three times. Light, shadows, and midtones. In this video shows the final print.
Is that a single layer print?
Oh... ok, I can see comment below. 3 layers :)
Another question. For development should I use warm water or room temperature?
If done correctly, it is sufficient to room temperature
Thank you very much, Artur. I did not know about the several exposures.

You do not need UV lamp. You can use regular halogen, it gives you light, temperature..... and UV rays! :D
Nice :)
