I created a little program that loads our .NEF images into OpenCV Mat objects. I also tried to use the samples coming with the source for converting to tiff or ppm. All 3 gave the same results, that the image looks like its been normalized in some way.

The image can be seen at https://04o62a.dm1.livefilestore.com/y2p7TPrRkirmyRkqZWfcwKZCK0Htr9OwJMe...

Might anyone have a .Net assembly (dll) of libraw that I can reference in Visual Studio projects? I attempted to compile the libraw source in VS 2005, but ran into many errors and I don't think I am experienced enough to pull it off.

I can in principle use libraw.dll in my VB.net applications, but I found that translating the header files is quite a lot of work.

Thanks. Nathan

What is contained in the unsigned gpsdata[32];?

How do I interpret the numbers? Is there any documentation related to this?

Here is an example -

Hi,

First off, thanks for the library and continued support. I have been using DCRAW for a couple of
years but recently I felt the need to jump the ship and turn to LibRaw. It seams like a solid solution but
I was experiencing some problems and it's gotta be something that I did wrong or a bug. So here it goes...

I opened photos taken by Nikon D7100 @iso 400, 800, 1600, 3200, 6400, 12800 and 25600 with LibRaw.
The problem is, the iso_speed values for photos @iso12800 and @iso25600 are '3.0000'.
How can I get the right iso values?
