I'm just in the process of scanning one of my old BW negatives. Using Vuescan and importing into LR3. For a largeish print, scanning as tif gives me a file of 96Mb, whereas scanning as dng gives just 18Mb. Obvious choice, I thought.
But …. The output from Vuescan as a tif is a positive, as expected. The dng file, however, with the same settings, comes out as a negative. And I can't find any way of inverting it either in Vuescan, or in LR3. Am I missing something?
And please don't tell me to buy PS.
