Icc/Icm PROFILE - DSE5400 & SENSIA 100

[gilou]

Hi there,

 

 

I would like to have your input related to the the profiling of a

DSE5400 scanner.

 

I mainly use Sensia100 slide Films and few kodak.

 

Here is the Process I use :

I bought few weeks ago a set of IT8.7 targets (all you need package)

from Walf Faust.

I use the Dimage Scan utility to scan the targets with the following

parameters :

mode: color positive - digital ice: on - grain dissolver: on -

pixel polish: off - color depth : 16 bit (not linear!) - auto

expose: off

color matching: off - exposure adjustment: none - image correction:

none - Scan resolution 900dpi or 1350dpi - Multipass 1x or 4x

 

 

Note 1: Many tests leads me to the conclusion that the profiles

were "better" is the resolution was quite low (900dpi or 1350dpi)

Note 2: I did not try to calibrate with Vuescan as the profile

generated by this software is very 'light' and seams do not seams

very accurate.

 

I use two profiler tools (IphotoIcc) and (Xlprofiler).

I also use the demo of colorshopX to display the generted profiles.

 

The results in the "real life":

Using these settings (and the Sensia target) and using these tools to

generate the Profiles, I still observe a magenta cast on my slides.

However, If i create and use the profile with the agfa, kodak or Fuji

Velvia slides, there is no more magenta cast on my sensia scans !

 

Question 1 : Did you observe something similar (when scanning Sensia)?

 

The profiles générated by XLprofiler looks better in the ColorshopX

tool, but i cannot see any difference on my screen compares with the

IphotoIcc profile.

 

Question 2 : How could I check if the profile generated is Good.

 

thanks in advance for your support.

 

Best regards. -gilles.

I did the same thing a while ago with my Multipro. I can only add that:

 

Try switching off ICE and grain dissolver. If there are dirts, try to remove them by the cloning tool. Better yet, try scanning at a higher resolution (perhaps 2800dpi) and then downsize it say by 50% before use. 8/16 times multisampling would not hurt either.

 

Also try outputting in 16 bit "linear" mode. I find the profile created by a "16 bit linear" scan looks more natural.

 

Finally, sometimes color cast is inherent in the film itself. I dont use Sensia much but I can tell you that the color cast in Provia (most of the time) and Velvia (some of the times) are really quite noticeable.

Thanks Chris,

 

I'm going to try the 16bit/linear tonight.

I also see the colorcast on velvia and astia, but it is less obvious thant on the Sensia.

 

The thing I still do not understand is : why the result of a Sensia scan is better using a kodak or agfa profile than the sensia profile ????
