I simply omit the colour toning step as it's obviously not needed. The advantage is you only use RawTherapee and GIMP, that makes it easier to reproduce.You're very welcomeįor what it's worth, I actually use a simplified version of the same process for B&W negative conversions too. I'll keep a reference to this thread for future use. I can't judge your process in detail because I'm only scanning B&W and have no experience with color. As such, even if there was compression taking place at the point of capture due to tonal range in the frame (and there isn't - that's not how it works the camera just clips anything outside the sensor's dynamic range), inclusion of the border wouldn't have any detrimental effect on the capture. it's just unexposed film, so it's equivalent to pure black in photographic terms. You can see that the RGB levels for the border and all the other sampled points are virtually identical (within +/- 1 or 2%) - which is exactly what you'd expect, since the border isn't anything special. I've sampled the border (the point furthest to the right) and various additional points that represent the areas closest to black in the original captured scene. I'd be delighted to learn of precise, repeatable methods that are better than my own, and I'm more than happy to ditch mine when I do.īy adding a border the original histogram is compressed with more white than is in the negative.Further to my previous post above, here's a portion of a negative - captured with border - in RawTherapee (it's the same photo I used in my video demonstration): Hopefully this discussion might encourage you and others to share their own step-by-step instructions for colour-accurate negative conversions - either in this thread, or separate ones.

Feel free to try it, though, and post revised steps and example pics with your improvements. But you could do as you describe - though I think you'd want to keep exposure settings consistent for the leader shot and the actual photos, otherwise you'd get a different set of RGB values when sampling the film base with the colour picker in RawTherapee, the colour toning required to equalise RGB values (removing the film base tint) would be different as a result, and it wouldn't apply accurately to the borderless photos if they were captured at different exposure settings to the leader. There were no errors, crashes or bugs revealed during our tests and response time is good.Why don't you take a copy from the leader of the film as a reference instead of adding extra white for each frame.Because I don't My preference is to have everything I need to work with encapsulated in one stand-alone DNG file, rather than having to rely on a separate file or files for reference.

When you finish editing, all you need to do in order to save the picture to your hard drive, is choose the output folder and click the “Start Processing” button.Īll in all, RawTherapee Porable is an efficient software app for editing pictures and converting them to more common formats.

There are also simple options, such as cropping, resizing, rotating and distorting photos. You can tinker with the image and edge sharpness, micro and simple contrast, simple and impulse noise reduction, RGB curves (Red, Green, Blue), vibrance, channels and HSV. You can save pictures to PNG, JPG and TIF formats with different compression values, modify the exposure levels, highlight reconstruction, enable shadows and highlights, adjust the light, contrast and chromaticity. The straightforward interface is comprised of a folder structure, a tabbed panel from which to choose the editing tools and a preview window.
