Subject: Re: filmscanners: Mounting fluid/flatbeds
| Mounting fluid has been mentioned in connection with drum scanners.
| It can also be used succesfully with flatbeds !
| We use both and using fluid with negs and trannies on the flatbed
| definatley gives a visibly better scan.
| Main improvement is in recording shadow detail and overall sharpness
| seems to be marginaly improved,Ive also tried it with prints and there
| were benifits there as well.
| We use a product called Kami Fluid which leaves no mess on the original
| as it evaporates.
| Below is some information which may be of use to those of you chasing
| the Holy Grail of perfection
