I expect also to need some reversal s/w for lightroom or photoshop
Vuescan is capable of converting scans of negatives to positives. It has been several years since I used Vuescan, but as I recall, it was sometimes difficult to find the right combination of settings that would result in a good positive. But with help from Photoshop/Lightroom, I was usually able to get acceptable results from my Vuescan color files.
More recently, I have been digitizing negatives with a digital camera and converting them to positive with Negative Lab Pro (NLP), which is a plug-in that runs in Adobe Lightroom. For black and white, I was able to get satisfactory results in Photoshop with no additional software, but for color, I think NLP is probably worth the added cost and complexity. I now prefer working in Lightroom compared to Photoshop, so I have been using NLP for my black and white inversions as well.
