Although the NYT has a piece on the importance and power of touch, I want instead to direct you to this UM personal website, a collection of beautiful photos of Michigan and a ton of other places (like Ann Arbor!). The photographer points out how cameras don't really capture exactly what we see with the human eye, so indeed you do want to review and modify your digital photos but should not consider it modifying the record of reality since that isn't what you captured anyway.
The point being, besides I hope you have a good color monitor, that color is an immensely powerful factor for the human visual system.
