When I upgraded Lightroom to the latest version the dehaze feature in Effects is missing. Does anyone know how to get it back. I have not tried to reinstall.
Assuming you are using Lightroom CC, check the About dialog for the version number 2015.x.x instead of 6.x.x . Sometimes LR gets confused about what mode (subscribed or stand-alone) it is running in. If your LR CC is running in 6.x mode, log out and back in.
