yes it was good to see that we schould not only look at curves and measurements of the light-physics. just try it and lets see what happens.
an other point for me to try it with any led-lamp was that some films have other basecolors (foma - blue) this also must have an influence at the printing but nobody cares.
next thing ist to get a stronger light and building an diffusor head.
edit 2 examples
the ring is 4x5
the grapes are 24x36
both printed on kentmere vc 23x18 cm glossy
the grapes filter 0
the ring filter 4
