why is Adobe incapable or unwilling to implement a more powerful Ken Burns effect feature set in Lightroom slideshows?
It seems incredibly simple to do with the resources Adobe posesses,
I firmly believe that the Ken Burns effect is one of the most powerful and evocative tools in a slide show presentation. The current implementation of this in LIghtroom feature is laughably limited.
Common Adobe! you can do better - Apple's Aperture had a far superior Ken Burns capability some 10 years ago.
