I do like your TIFF idea. Tell me more. 🙂
I have a Nikon D700 and a Sigma DP1 with a Foveon sensor (and I used to have a Sigma SD-14). Nikon raw support is no problem. Everything supports Nikons. But the Sigmas are such niche products, and their Foveon sensors are so unique, that raw support is difficult to come by. Aperture has never supported any Sigma raw format. Lightroom supports some, but their X3F (Sigma raw) decoding loses most of the unique character of the Foveon sensor and clips dynamic range. So for years my method for dealing with these Sigma raw files has been to use the very simple Sigma-supplied Photo Pro software to output low contrast 16-bit TIFFs with zero sharpening, and import these into Aperture where I bring the contrast back up with a curve.
The advantage of bringing in a low contrast 16-bit TIFF is that doing so preserves the full dynamic range of the Foveon image so that the resulting TIFF is effectively the same as the original raw file, provided I am careful to get the white balance correct before creating the TIFF. Also, the TIFF preserves the unique Foveon image quality for which I bought the Sigmas in the first place. I'm even comfortable tossing the raw files afterwards, as there are no more advantages to be gleaned once the TIFF is created (Foveon raw files don't require demosaicing, so there's no loss there anyway).
Obviously, NEFs are different and have to be demoasiced, but I'm starting to like the idea of breaking free from raw formats and Digital Asset Management software and just converting all of my raw files to 16-bit TIFFs.
Let's face it: half the reason we're trapped in these DAM applications is because everybody decodes raws differently, and the adjustments don't carry over from app to app (though, intriguingly, Capture One Pro has preliminary support for importing Lightroom libraries, support which preserves critical adjustments such as white balance, exposure, and cropping). I guess my complaint is that, rather than solving problems, these applications have created all new problems which we never had before.
Ideally, camera manufacturers would include the option to save unprocessed 16-bit TIFFs in-camera. My D700 will save TIFFs, but only 8-bit TIFFs, and they're processed like JPEGs, so that's a non-starter.
So the idea of going back to folders and TIFFs — which is how I worked back when my old Canon 10D was practically state of the art — has a lot of appeal to me.
