Publish to the cloud
When the LR3-Beta came out, one of my posts highlighted the less obvious aspect of the new Publish Service – the hard drive option – and I mentioned that I’ve already found it handy as a stepping stone between LR and InDesign.
There will be plenty of other uses too, and I’ve already seen a comment about using it to maintain a store of JPEGs for display on a TV. One possibility is for saving photos to the cloud – though you’ve got to wonder what upload speeds Mark Wilson’s getting.
