I have been using Vuescan to scan slide film and color negs with a Coolscan V for many years with great effect. recently, however, with the latest updates I am experiencing problems with the color negs, The preview starts out very good, bright and clear, and then when it ends the image is darker and looks as if the image has been shot through a nylon stocking, or similar filter. The scan is also dark and hazy. I cranked up another computer with a Vuescan program from 2018 and the previews and scans were as they should be. Is this a problem for anyone else? The Vuescan updates are 220.127.116.11 and 18.104.22.168 and 22.214.171.124 as well.
