Yes, that is correct... when scanning things just don't look identical. I have noticed lots of times that it comes out a lot darker. So, to begin with I think this deals with the quality of your scanner, and how good / intense the light is. The more expensive, the brighter the light, and the better the scan, that is how it works.So, to answer your question, I do not think there is anything you can do in the scanning process unless that is a option with the scanning software. But don't worry, you can do all your color / light correcting in Photoshop.One of my favorite options to color correct is the Selective Color. It allows you to target different colors to make them more or less intense. Like it has a red, cyan, magenta, yellow, blues, greens, white, neutral, and black. Also, you can use the basic color balance option, or go into the RGB channels. Thanks for reading!
