as said in my previous post, color casts have different origins and causes. Summarized, one can explain it like this:
- the microlenses sensors is one reason: this makes them not suitable for use on view cameras at all, and I would really no recommend it at all, if shift, tilts & swings are needed.
- a second reason are shifts with the light falling at a different angle on different areas of the sensor: this can be corrected with a white reference for the corresponding shift. Obviously this happens with all types of sensors.
- a third reason is the linear response of the sensor (or non-linear) to the light, from shadows to highlights: this is again sensor related, and in this Kodak sensors have a less linear response than Dalsa sensors, starting efectively with the 16 MPx models. This can also be correted by white references for EACH shot, when it happens.

Hi Thierry,
I am new here and would like to ask you if the color cast is visible in B&W, and if the desired end result is in fact black and white, does it really matter at all?
If the question sounds a little boorish to anyone, pardon my impatience.
I am considering
ALPA 12SWA with one of the DBs » __
e75__
HD3__
P45+ and few lenses to start:
Schneider Apo-Digitar 5.6/47mm XL decentered
Schneider Apo-Digitar 5.6/24mm XL ____ or ____ Rodenstock Apo-Sironar 4.5/28mm
I was told that Leaf goes nicely with ALPA Cameras, mostly 70 to 80% of ALPA users purchased Leaf Back. However, considering the downfall of the Leaf system shortcomings I am avoiding it even though their representatives are more than happy to assist at any given time.
So my choices are H3D which I really like I have to admit that, and P45 which I can't say
much since I have not tried it and further more not many people are complaining.
One DB that I found publicly silent until the announcement of Hy6 is Sinar Models,
so the Sinar Hy6 concept better be good or else???. Reading through the threads of few customers I am happy to see that e75 supports all platforms with the appropriate adapter of course. However, I have failed to find one ALPA customer with one of the models, perhaps e75 which is the one I would consider.
Apparently all models with the exception of Leaf Aptus require more than one cable, how many? not sure.
Any info would be highly appreciated, perhaps one of your customers would be of great help. PLEASE, `NO SALESMANS`
On the account of the lenses;
Schneider Apo-Digitar 5.6/24mm XL ____ or ____ Rodenstock Apo-Sironar 4.5/28mm
I was told that
Schneider Apo-Digitar 5.6/24mm XL is more designed for Landscapes & has a bigger Image Circle, and
Rodenstock Apo-Sironar 4.5/28mm is designed more for table top,
so which one?. The price difference is enough for me to go for
Apo-Digitar 5.6/24mm XL if the
performance of the
Rodenstock’s Apo-Sironar 4.5/28mm is not apparent to justify the price difference.
Any thoughts on Lenses would be of great help too, because I would like to receive the Alpa System including the digital back, adapters, etc. by the 1st of March.
Anyone using distance Laser Meter by BOSCH, LEICA, HILTTI ?
This turned in to a rather more than one question, but what can I do since the total cost is a little more then few bags of money.
Thank You for your patience.
Ciao
