I don't have the hardware to scan negatives, and I was trying to get the cheapest way of doing it - that's why I am trying to go around enlarged negatives.
Another question: once the paper is ready, only sunlight or UV lamps will be able to impress it, right? Normal house lamps (fluorescent or tungsten) don't emit in the UV band?
And what if I buy a UV lamp and place in the enlarger? So many ideas...and I still have to find the chemicals.
