The camera is a Nikon1 V3, I shoot RAW.
When developing there are grey edges around some colors, purple especially, that do not show up on shots from the same objects taken with other camera's.

I would guess that you have defringing turned on, i.e. a non-zero amount value and a pinkish color range selected, and either saved as your Lightroom or Camera Raw defaults for your camera or in a preset you've applied.

Yes,

I changed it and now it is OK, thank you, but I needed the defringing for the lens used in most other situations.

If you have defringing set on as a default then you'll always have to keep watching for this problem where colorful objects get gray halos.

For me fringes are usually purple or blue or sometimes green. Do you get pink fringes from your lenses or does your color-range need adjusted?

I was trying this camera with the beautiful 32mm ƒ/1.2 and at full aperture there is definitively fringing, I removed it quite strongly, but that did increase the quality of the pictures, I hate those coloured edges.
I actually never realized it would have such heavy effects on other kinds of edges.

LR cannot tell whether a fringe is from the lens or something else that is supposed to be that color in the photo so everything that color gets grayed out.

1. You can try to fine-tune the hue range that is being affected by the Defringe control. You can use the option/alt-key visualization to assist you.

2. You can use the local correction tools (e.g., Brush) with Defringe (namely, the local control channel slider named "Defringe") set to -100 to tell ACR/Lr not to apply defringing to a specific area. That way, you can effectively "mask off" areas of the picture that are being adversely affected. The advantage of the technique is that you can tell ACR/Lr precisely which areas to avoid defringing. The disadvantage of the technique is that it requires per-image work.

Eric,

Thank you for your reply.
I had set my own camera settings, based on a very different picture that needed a high amount of defringing, and then the other picture gave a problem.

I shall look at the local option, especially the removal with a -100 setting, very smart.

Thanks for following up, Eduard.  I do not recommend including the Defringe adjustment as part of the default camera settings, because (as you've discovered) the necessary settings vary on a per-image basis.  And on tricky images, it will often be necessary to apply/modify the adjustment locally.  Hope this helps going forward.
