Hi HeldInTheMoment ,
Lightroom 6 does not have the Dehaze feature. You must have the Lightroom CC in order to access the Dehaze slider.Refer Which Should I Buy, Lightroom CC 2015 or Lightroom 6? | Laura Shoe's Lightroom Training, Tutorials and Tips
Please Contact Customer Care to get help regarding switching to CC.
Your other alternative would be to wait for the next release of the standalone version of Lightroom. It will "probably" have the dehaze filter included. But it will be a paid upgrade. Historically upgrades in the US have been $79.
Yes you could sell LR6 and subscribe to LR CC.
You would need to de-activate the product and persuade somebody to accept your license.
The real problem is that most potential buyers think that used software is pirated. But Good Luck.
Thanks everyone, just talked with Customer Care and I would have to sell my license and purchase CC...with no option of any credit if I were to switch without selling.
Perhaps a missed opportunity for Adobe sales? Unless you purchased from a re-seller or on-line store.
