Hello there, I got a scanner recently to try and scan my negatives and slides, the Canoscan 9000F, but I can't work out how to get the colours right on the final images. The software I'm using is Scangear. I use the Advanced mode and when I hit preview I can see all the images with good colours, but then when I hit scan they all go kind of purple and green, without me having changed any setting. Does anyone know why is this happening? I'm sure it's just a beginners problem. Thank you so much for your help, I have piled up a few rolls waiting to be scanned and this is quite frustrating.
