First post from me... I'm not sure where to post this question as I don't know the name of the issue! Twice now I have exported a photo from LR cc absolutely fine but when I have moved the same photo into a new collection, a light dot that almost looks like a brush mark has appeared on the image just below the eye (both in LR and when exported) and it isn't possible to correct it with spot healing. The last time this happened a small grey dot appeared (on a b&w photo) and I couldn't get rid of it.
Does anyone have an idea of what is happening here?
Thanks very much
Yes, that does look like a "spot" from an adjustment brush.
Check the edit history of that photo to see if it has any brush work.
