I store my photos on external drive and use smart previews (stored on C:\ drive). Now I realize that when I unplug the external drive and export such a photo from lightroom catalog, there is no prompt that original photo is not available and it exports smart preview photo - which is much lower quality.
Sometimes external drive can unplugged accidentally or someone forgets to plug it. How to avoid export smart previews instead of original?
Is there a way to turn on prompt in this case? I think it should be...
No, but you have plenty of indications that only a smart preview is available.
On "export" window?
