With the new Adobe Portfolio, will there be a way to publish projects to Portfolio straight from Lightroom?
As of now there is no option to publish projects directly to Adobe Portfolio.
The concept of Portfolio is that it uses photos that have already been uploaded to Adobe's servers, in this case by syncing Lr collections.
LR has the web module for those already who have hosting, with direct upload via FTP. Adobe is introducing a number of publishing options including Slate with parallax scrolling, Behance with collaboration, Portfolio for sharing and In Design Publish On-Line for review and Epub. The latter being ideal for those who can create pages and interactive content, without coding, HTML or CSS requirements. It’s obviously an evolving environment that’s worth watching.
