Yes, I am on Tiger, and the problem only occurs with .nef images.
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.
With the RAW format of a Canon EOS 20D (.CR2) everything works fine.

Hi all,
I try to load a RAW image (e.g. .nef Nikon RAW format of a D70)
with -initWithContentsOfFile:(NSString*)filename. This creates a
NSImage object with one NSBitmapImageRep inside.
But the NSBitmapImageRep seems to be only a thumbnail (160x120
pixels) of the RAW image (3024 x 1998 pixels). Am I doing
something wrong? All other image formats seem to work.
In other words, is there another way to get a full resolution
NSBitmapImageRep of a RAW image?
I'd file a bug on that, .nef files are supported, according to the
docs:

You are on Tiger, right?
