That should be useful. I have generally given up on P99 as a platen material because it degrades over time and differs from batch to batch. I'm currently using Epson 4990 holders on top of the P99 platen. I routed the platen for the holder openings. The Epson holders are good, but I doubt they hold the film perfectly flat at an equal height - you tend to loose resolution at the edges of the holder. The 120 holders for the Epson suck, and I get variable quality in the scans.

I had a Coolscan at one time. It did a very good job with very fine-grained film, but it did a terrible job with grainy film.
You still have to spot with a dslr scanner .

The Screen Cezanne has a couple of problems in the deep shadows
1) It's got a low dmax - yes it's not that great at all. However we could probably live with that if it wasn't for
2) The scans are pre-processed in firmware to increase colour separation. For example, if you want to make the cyans more 'pure' you would decrease the level of the red channel.
And this is exactly what the Cezanne does. The problem is that it decreases it to zero and not the film base level. This means that you don't get a consistent black across the whole frame. If you set the black to the base level, you clip areas of complementary saturated colour. Fuji Celsis scanners supposedly have the same problem. It could be great if we could work out how to disable this bit of firmware but I don't think it's possible
3) Noisey blacks - they pick up lines of digital noise when the gain is ramped up.
4) High contrast bleed. Specular highlights bleed across into darker areas.
So overall I consider the Screen Cezanne a poor scanner for transparency film. Velvia has particularly dark base level. Provia isn't so bad (actually provia and velvia have the same dynamic range, it's just that Velvia 50 has a really dark black)
I use my Screen Cezanne for Colour and black and white negatives for which it is absolutely stunning (better than any drum scanner I've used for resolution and pretty good at colour too)

Hi,
does someone know if the 5000 & 5500 lamps are interchangeable?
Best regards,
Martin
I'm pretty sure they are. The 5000 uses 4 of them, whereas the 5500 uses 2.

Hi . . . The lamps are compatible. They are special ones that have a silver foil on one side to reflect light in a certain direction.
Hence when fitting them ensure the 'SCREEN' label is facing the correct way. . . (Labels on the machine tell you how to fit them.)
There are 4 on the 5000 . . 2 for Transmission, 2 for Reflection
There are 3 on the 5500 . . 1 for Transmission, 2 for Reflection
Hope this helps.
Thanks guys, good to know!
Got my hands on a 5000 which resolves better than my 5500.
Set it up yesterday, but it has a low-light warning with the elder lamps, so I'll try to swap replace them with the newer 5500 lamps.
I'm only using the transmissive lamps and keeping the other as a spare.
Best regards,
Martin
