When converting a color photo to black & white and adjusting the image, it looks fine in Lightroom. However, when exporting the photo and for example posting it on Instagram, the photo suddenly receives a blueish colorcast. The same applies if someone downloads an image through a shared Lightroom Gallery and posts it somewhere. The problem is, Lightroom still keeps the photo as an RGB file. I know, I can change an individual file in Photoshop to grayscale, but it's not really a solution to the problem. Is there anyway to assign a grayscale profile in Lightroom to a photo? It really would be great, if Lightroom could convert a color photo to a true grayscale one. It would not interrupt my current workflow.
The attached file shows on the left, the Lightroom file and on the right the same file posted on Instagram with no further adjustments. But, the problem is not only visible on social media, but even in the Finder of MacOS.
Feature request, Import and export, Presets or profiles, Problem or error
I honestly think the problem is related to the file being a color file. I used to work as a photo editor for a magazine for a long time. We came across the same problem every once in awhile. When a profile is not set to sRGB or grayscale, the images change their color if uploaded to websites or social media. I think they use some software to convert the images, but it's not doing a good job converting the color profiles. Therefore you always need to supply the perfect file.
Especially when sharing images, it would be great, if Lightroom could just export black and white, as grayscale files. Or if there would be a Plug-In doing such a thing...
