According to March 2006 thread about the same topic, (quoted from
Michael Ehrmann's post):
The only way I found to work around this bug is to load the image
with CIImage, as suggested by Daniel, directly from disk. Although
using CIImage -initWithData: doesn't work. So I have to store the
image temporarily on disk and load the file in order to get the raw
image representation and not the thumbnail.

I've used an NSTableView as the source of the images, the user

I used [NSImage imageFileTypes]; to allow them to only drop
files that NSImage can use.
However! When I drop on a NEF (Nikon RAW) file, it gets the size
totally wrong, I even outputted the image as loaded from disk
into an NSImageView, and it's tiny. The pictures are from a 7
megapixel camera, and look fine in Preview, but in my app, they're
the size of the thumbails shown in Finder!
An NSImage's size isn't necessarily its width and height in
pixels. You may have to set the width and height to the pixelsWide/
pixelsHigh values of the NSImageRep in the NSImage to get it at a
size where each pixel is equivalent to a unit. If the NEF file
specifies its resolution as, say 360 dpi, it wouldn't be
surprising that it might show up as rather small.

No, I checked that already.
Representations Width: 160, Height: 120
That's the only representation available.
