Hi Ann, I seem to recall that you do not use Lightroom and my 'recipe' was intended for Lightroom users. I'm sure it could be done in other image processing tools in a similar way, but it's been years since I used anything but Lightroom for this kind of work. If you are using Lightroom and want to give it a go, here's the basic workflow.
— Use a high magnification copy setup to photograph your negatives with your digital camera. Be sure to save the exposures as raw files. Then import the raw files into Lightroom. - Select a negative and go to the Develop module - Use the white balance sampler in the Basic panel to sample the orange color from the negative's rebate or a clear spot in or between images. That will do a close approximation of removing the crossover mask. - Use the Tone Curve panel in point curve mode to invert the image. You do this by dragging the white point from the top to the bottom and the black point from the bottom to the top on the point curve. Shape the curve with additional points and adjustments until you get the overall rendering you want. Note: Once you've inverted the tonal curve, all tonal adjustment controls will work inverse to their normal operation. The idea is to rough in the crossover removal and the inversion. Once you have a decent result, save the settings as a Lightroom preset so you can apply it to all the negs you're working on easily. If you're okay with using the inverted UI, you can finish the rendering right then with the raw files as they are. I usually find it better to export all exposures with auto-import enabled into 16bit TIFF files and then do finishing work on the TIFFs because the UI adjustment controls will operate the normal way. --- Take a look at https://www.flickr.com/gp/gdgphoto/97c6Ga to see a color negative roughed than finish rendered to a good positive rendering. Let me know if you give it a try. :D G > On May 19, 2020, at 6:07 AM, ann sanfedele <[email protected]> wrote: > > hmmmm .. do I want to try this?
