How big are smart previews?
- about 1mb when I last looked
Am I able to edit them as if I had the actual file?
- pretty well. Think of it as equivalent to Quick Develop - good enough ball park adjustments
What do I do when I have filled up a Smart view preview with the 20GB of storage?
- Not sure. If you have the Photo bundle (PS+LR) there isn't a storage limit
It will automatically sync with the desktop versions without telling it to do anything?
- yes, that's the beauty of it
I've never built Smart View previews
- When you sync a collection, LR sends smart previews - as you happen to know. But for using for using LrM/LrW you don't need to know that background information because all LrM/LrW smart preview activity happens behind the scenes.
Is there a quality difference that is noticeable while editing?
- I regard adjustments as ball park, not final. I might share the pics on FB or email them to a friend, but review them on a colour managed monitor before I might print them. The advantage for me is that I've had time on the train to contemplate how I want the picture to look, and then in the pub I have made those ball park adjustments. So I've saved time, and when I am back chained to the desk I can focus more on the final fine tuning.
I seen something about collaboration on Lightroom Web, does this mean that my friend who also has Lightroom can go in and work on a file I've made?
- LrW doesn't have adjustments.
- When you share a collection with someone, they only have favourites and comments, so LrW is more about sharing a shoot with someone who might want to choose which pictures they want. When you get back to your desktop, you can see their favourites and comments, and can easily select the ones they want
- As the account owner, when you review a collection in LrW you get the Pick/Reject flags in your browser and can use the P / U / X shortcuts. It's a bigger screen than your iPad/Phone, and colour managed too (though the lack of CM on mobile devices doesn't matter if you remember that you're doing ball park adjustments that save you time later).
