I have recently acquired a Colourstar 3000( the 8 channel version and more questions on that later). I have a Paterson PCA61 which is much simpler to understand and because I was familiar with its method of calibration which is to use the "perfect print route" I was advised that this was probably the best way to set up the Colourstar.
I had been given a Fuji test neg and a Fuji print from the guy I bought my Jobo from. I am pretty certain the neg and print are Fuji's own and were supplied to customers setting up analysers, doing ring arounds etc
I think I have learned a lot from getting as close as possible to the Fuji print but a couple of things still puzzle me. I hope some of you can provide answers
The test neg and print is that of a Japanese girl with a white cardigan in a garden, holding up a colour chart with writing above and surrounded by two colours of flowers( golden yellowand deep red) and a stone statue. In other words all the thing you need to test for colour balance.
I have got close to the Fuji print in terms of the colour chart but the best filtration compromise leaves the golden yellow flowers not quite as golden. I can get close to the golden colour but only at the expense of making the print too warm. So I end up with correct flower colour but at the expense of an over tanned face. The red flowers are spot on.
Somehow Fuji seem to have achieved a fairly neutral skin tone and a very golden set of flowers. Fuji's print also looks brighter. Almost as if a brightener has been added to the chemicals. I do use a stabiliser/brightener but can't match Fuji's brightness.
In my print her white cardigan is slightly less white, her face more tanned and the three squares for the black, dark grey and mid grey are slightly more brown.
My conclusion was that all this points to increasing Y and M slightly but when I do that with various small combinations of Y and M around the chosen filtration, it helps some things but at the expense of others.
The Fuji print paper has no brand mark but has to be at least 10 years old as is the neg. It is also glossy whereas mine is lustre. This may account for my print looking slightly less bright.
In summary the main difference is my print has a more tanned skin tone yet a less golden flower tone.
Any ideas as to how I might nail this down or could it be that a combination of different Fuji paper and a lustre finish as opposed to gloss might account for the differences?
