I am currently using a Canoscan 8800F scanner with Vuescan. Plan to upgrade to a dedicated film scanner - the Plustek 8200i AI.
I learnt the above-mentioned scanner comes with an IT8 target for scanner calibration and I briefly read somewhere that calibration is good only for positive film (slide).
While I have some "old" slides, shot a few years ago, I plan to shoot mainly black and white and color negative films. If the above is correct, then I do need to calibrate the Plustek.
I hope to hear from anyone who has experience with scanners, thank you.
