What does Smart Curve do that Photoshop's curves dialog doesn't? It looks the same to me.
I adjust white at the brightest color (R,G,B=255,255,255) first. pick the rightest points of R,G,B, then move it separately at where the rightest peaks of histogram reach at the right edge (#2,#3)
Click the whitepoint picker and click on a white spot in the image to do this automatically.
Sometimes, some channels might reach at 255 before the white will reach 255,255,255. it maybe saturation problem which scanner couldn't handle. in this case, just ignore it and adjust it later.
This isn't ideal, because it's clipping some colors.
I think this happens because some inks, at high saturation, are simply brighter than the paper. Clipping them to the paper brightness will alter the color.
Usually, these saturated colors go away after filtering. So, in theory, a better way to handle this is to descreen before curves. The supersaturated colors are no longer there, so you can set the whitepoint to #FFFFFF without clipping colors.
However, you need to do processing in 16-bit for that to work. PS greycstoration can do this pretty fast on GPU with a good graphics card, but will be very slow on CPU. Not all other plugins support 16-bit (all high-quality plugins will). Depending on filtering and your machine, it may not be worth it.
Secondly, adjust the dark point. unlike the white, paintings aren't always true black. and since screening divided dark colors randomly, histogram have lost the correct blackness
This problem also goes away if you filter before adjusting.
