How to invert pictures in Lightroom ?

How can I invert pictures in Lightroom ? If I have a black&white negative scanned and imported to LR, there is no possibility to invert this to a "positive". This is possible in Photoshop, why not in LR ?

      Because Lightroom is designed for a digital workflow.

      To invert pictures, use the Tone Curve and drag its bottom left point to the top left, its top right point to the bottom right.

      I’ve thought for years that this would be a useful feature, arrogant forum spooks be damned.

        So including you, that's - what? - half a dozen?

        There's nothing remotely arrogant about pointing out that a given "enhancement" is likely to be of minimal, niche interest to most Lr users. Call it managing expectations.

        It's also pretty intantile to try and characterise the opposing view as "agrrogant", too - do you always go into petulant name-calling mode if someone doesn't share your opinion?


        Self-evidently the need for a "Negative" button is niche; or after all these years, we'd have heard a lot more about it, from a lot more people - wouldn't we?

        As explained already by john beardsworth there is no need for a "button" to invert the image data. Set the Tone Curve as explained at the below link and then save it as a Develop preset with just Tone Curve selected.

        I do scannerless capture using a DSLR camera and use PS for initial processing with LR for final Toning and cataloging. The DSLR raw image file is NOT compatible with most dedicated scanner software due to differences in the scanner and DSLR profiles. While it is possible to process DSLR B&W negative and Color slide images using only LR the same is not true for color negatives. This is due to the "complexity" in removing the orange mask and correcting the individual RGB channel gamma, which is "unique" to each film type and emulsion batch variation.

        Mark Segal and I did an extensive study on how to process DSLR B&W negatives, Color negatives and slides using two different workflows.

        Here's a full-size image of a 35mm Fuji Super G100 color negative (circa 1999) captured with a Canon 5D MKII and processed with PS and LR as detailed in the above article.

          I love working with LR for my digital - but when I want to edit my film camera rolls... I have to go to another program like PS just to invert and save as tiff and THEN import in LR for editing.... expanding the work flow and multiplying the file count (raw AND tiff)

          I simply don't get why Adobe don't add an "invert negative" tick ...that inverts the photo but keeps the rest of the develop sliders as they were supposed to. This would enable me to keep the pipeline in LR.

          Is there anywhere I can put in a wish or something for the developers... I have many photographer friends that would love to have this option.

          Cheers

            You should be doing the inverting of the negative in your scanning software.  If your scanning software doesn't invert negatives you need better software.
