Sinar CaptureFlow doesn't seem to support opening raw files (I'm looking at using the back in the field so tethering isn't an option anyway). Neither Lightroom nor Capture One supports the raw format, so Iridient Developer and RawTherapee are the only options.
The "CaptureFlow Studio" supports all kinds of raw files (sti, dng) from Sinar digital backs (series eMotion included). At the moment, Multishot images from Sinar CaptureShop 5.x ( ".sti" raw data) opened are, displayed and exported as 1-shot images.
Also, dng files (1shot, 4shot, 16shot) of sinarbacks produced by Capture Shop 6 & CaptureFlow Studio fully supported by Adobe applications (Bridge, Photoshop, Lightroom).
I have extensive experience in the use of Sinar CaptureShop 5.x, 6x, CaptureFlow Studio, but only with tethered digital backs (SB 54M, eVolution 75 H).
I suggest before you copy the files, to connections back via firewire, start the app and let it downloaded the White Reference file. This file, logically, is embedded in internal memory of digital back. It's important, the application to recognise the digital back.Instructions for connecting the digital back and import the files via the "CaptureFlow Studio" can be found here:
https://www.dropbox.com/s/cy3pq49og7cf4je/SINAR_MANUALS.zip?dl=0Τhe zip contains three files:
1) User's Manual eMotion 75.
2) User's Manual* "CaptureFlow Studio", html file opening via Safari or Firefox, look paragraphs 3.3, 5.2, 6.3.7, 8.4.
3) ReadMe v1.4.1.pdf file, look paragraphs with a red border.
*User's Manual Sinar Exposure & CaptureFlow Studio it's the same.
Any thoughts? I'm not familiar with backs of this age. Is it normal? I'm worried that, though fixable to certain degree in post processing, the green channel on the back may have problems, and could result in clipping or lose of dynamic range in certain scenarios.
The greenish color, means that was reset in WB. This can be done either by application bug (usual in older versions), either by choice (Process Tab>in the WB panel>in the upper right corner> drop down menu>select reset WB). When open the file in "CaptureFlow Studio" you will notice that the slider on "tint" in the WB panel, is set to 0. Dont worry, the processing in raw converter is non-destructive and fully reversible.
Choose the correct color profile to the Process Tab>"Input profile" panel and start in the WB panel with values: Color Temp>5679 (conditions for daylight or flash studio) & Tint>90. Continued by fine tuning.
Good luck!
