Does View NX2 have a problem opening large TIF files? I tried to open a TIF file that was a 360 megabit file (125 megapixels) and it crashed View NX2. The file was a panorama generated from 18 NEF files with Photomerge in CS5. It will open it if I save it as a compressed JPG file.
I am using an i7 2600K processor with 16 GB of RAM and CNX2.3.1 64 bit and VNX2 64 bit and I have no problem with very large TIFFs. I did have problems when I was running the 32 bit versions as there was just not enough memory available to handle the files. I have been processing 4 channel (16 bits per channel) from huge 6400 dpi slide scans which produces images larger than 8000 pixels on the long side with no issues.
I just checked one of my 4 channel files (R,G,,IR) 16 bit and it was 408 MB but while CNX@ can open that file it is not a file it can process because of the IR channel and I first have to process it in SilverFast HDR Studio to convert the file to a normal 48 bit file with the IR channel already applied as a dust and scratches step. This generally takes them down to under 300 MB before I process them in CNX2. Your 14750 x 8500 file is huge and I would assume a minimum of 16 GB would be required for a file that large. Make sure that you also turn off the editing cache and then try it.
I don't know if this is relevant, but I fould it on another forum.
"From the readme file that comes with CNX2.....
11. Image size The maximum pixel size allowed in Capture NX 2 is indicated below. An image whose size is larger than the size indicated cannot be opened. Please note that depending on the kind of edits you make, you may encounter some problems even though the size of the image you are working on is equal to or smaller than the maximum size.
The maximum pixel size: 15000 x 10000 pixels "
I have certainly opened files with a pixel width greater than 15000, but the height was much less than 10000, so maybe it is the product of the two...
