P: Ability to invert negative scans to positives (color and black-and-white)
I would dearly like to see the Lightroom 4 Beta team implement an additional feature in the final release. That feature would be the ability to take a camera+macro lens image of a B&W negative -- essentially a camera-based scan of a negative -- and invert the negative image to a positive image at the beginning of the development process in such a way that the resulting sliders in the LR4 Develop Module would not operate in reverse. As I understand it, this capability exists in Photoshop, but I don't own Photoshop. I do own Photoshop Elements 9, but that program only supports an 8-bit workflow, not 16-bits per channel, and round-tripping between LR & PSE9 requires the reimportation of a TIFF file that is more than twice the size of my NEF RAW files. Since this programming wizardry already exists in Photoshop, I would think that it would be a relatively simple matter to transfer and adapt that code for LR4 -- but then, I'm not a programmer, so what do I know...
I've been digitizing 40-year-old Kodachrome slides from my Peace Corps days in Africa, using a 55mm Micro-Nikkor (macro) lens, coupled to a Nikon ES-1 Slide Copy Attachment, and even on a D300s body, I can get truly excellent results. I can't wait to continue that work using the pending 36 megapixel Nikon D800 body with an upgraded f/2.8 macro lens (mine is the old 55mm f/3.5 design). I really, REALLY want to be able to camera-scan my many B&W negatives without having to generate huge intermediate TIFF files.
You can respond to this request by emailing me, Jeff Kennedy Thanks, in advance, for taking the time to review and consider my request. I LOVE Lightroom 3, and from what I've seen, I'm going to love LR4 even more. I REALLY appreciate the effort that Adobe takes to solicit input from the photographic user community.
BTW, if the feature I request *can't* be implemented right away, could the LR support team provide detailed, interim instructions as to how to use the "backwards" sliders, and in what sequence? That would be very much appreciated. I'm sure many older LR users have considerable analog image collections that they would like to digitize, and doing so in-camera is both 1) of surprisingly high quality, 2) MUCH faster than using flatbed scanners and 3) of much higher quality and resolution than flatbed scan and MUCH cheaper than professional drum scans.
