I updated my LR 6 to LR 6.1 and do not see the haze filter in effects panel as I think I am supposed to ... have restarted the LR program and re-booted computer with no change. Any thoughts as to what the problem is???
Adobe technical help chat room directed my to "forums" as he thinks this is a product problem ...

Slightly amusing as Adobe tech of all people should know that the dehaze function isn't and never will in be in any version of LR6 (the perpetual model) as a feature in the toolbars. It is only in the CC version of LR asa slider.
However... you can get access to it.
I've already created 21 presets (-100 to +100) and installed them in LR6, they work like a charm. For now.....
The presets are available on request, PM me for details.
