Yes Jimmy, Nikon Capture is sold individually for about $100. You can probably find it for less. The D70 comes with a one month trial version.
The Capture software gives you the ability to adjust images shot in raw mode. Raw images, Nikon calls them NEF's, retain more data. Any alterations to images performed in Nikon Capture can be reversed or adjusted, with no data loss, as long as the images are saved as NEF files. The images can be converted to tiffs or jpegs for use in other software programs.
I have a digital gray card that I place in either a scene or in front of a painting. You can use the software to adjust the white balance by pinpointing a spot on the gray card. The white balance setting can be saved and then used to correct other pictures shot in the same lighting. The really cool thing is that I can upload this same white balance to my D70. I can also upload adjustment curves.
