I printed the (_0018342.tif) developed in LR3 Beta 2 at 30x30 cm in the EPSON Semigloss Paper (250g/m2) that was posted in my last thread and WOW!!! It looks like a 24MB file from a u$s 3.000 D-SRL!!! (at least at this size, ja!) Full of detail, vivid color, VERY low NOISE and very sharp!
Conclusions of the success of this test: GRD2 lenses at f2.4 with spot metering (28+40mm with adaptor) + ISO 80 + LR3 Beta 2 RAW development engine. Now I feel that I can continue with my Night ISO 80 series. I´ll be posting the intermediate results very soon. Thanks to all who supported me in this discovery.
