In PhotoShop you can convert to a gray scale in a manner that keeps maximum tonal range. After saving you cannot convert back to color so that information is lost.

Is anyone aware of any documentation or publications on this topic? Additionally, I know many people that choose to scan black and white images in color then convert to greyscale.....again...any useful data or discussions on this out there? Thank you!
