So you could just open a raw file ACR/LR, do nothing and save it as a 16 bit file. That's dynamic range if you deal with a single shot. Cameras with bad dynamic range might record values in steps like 0, 1000, 2000 in dark spots while a high-end camera is able to record in steps like 0,10,20,30,40 etc. Dynamic range is not expressed by absolute numbers as any camera can record a number from 0 to 2 14. I'm not sure where you want to go with this. The RAW file is a digital interpretation of the CMOS voltage output, not a 14-bit per channel image like TIFF or BMP. Which one gets clipped? Could it be that it's the 16-bit TIFF? Why is that? Now open the image in Photoshop and change the exposure to 3. Open a RAW image up in the Adobe Camera Raw Filter and save it out as 16-bit TIFF file. The people who think that a RAW image has no more dynamic range than a 16-bit TIFF file, please humor me. Thank you very much for reading my rant, and any insight you may have into this problem is very welcomed.ĮDIT: Ok.

exr file without loosing dynamic range, and without having to slaughter a chicken and convert it's entrails into different exposure values under a full red moon? Maybe not directly, but perhaps to save out all the EV stops that contain unique range and combining them automatically into a 32-bit EXR file. I can't believe that it is 2014 and there is no way that a computer can do this conversion. Why would you go through all that trouble to painstakingly save different exposures of dozens or hundreds of RAW files since both the RAW and HDR files both contain the same dynamic range? This seems like pure insanity to me, because then you are making the classic mistake of making a human do something that computers excel at and humans do not. I have researched this matter quite a bit and the solution that everyone keeps telling me is to save different exposures of the raw files and them combine them into a 32-bit image. So naturally if you need an image with a lot of range, which I do, then one would assume that converting the RAW output of a camera into a 32-bit high dynamic range file would be simple.
The Nikon d3200 for instance brandishes 12,5 EVs, which is a lot considering it is an entry level DSLR. Modern cameras can pack tonnes of dynamic range into a single RAW file.
