• Welcome to the Lightroom Queen Forums! We're a friendly bunch, so please feel free to register and join in the conversation. If you're not familiar with forums, you'll find step by step instructions on how to post your first thread under Help at the bottom of the page. You're also welcome to download our free Lightroom Quick Start eBooks and explore our other FAQ resources.
  • The November 2019 Lightroom updates are now available. Lightroom Classic includes the ability to export the same photos as multiple sizes/formats in a single export, content aware fill for panorama edges and more. It does require a catalog format upgrade and there are updated system requirements, so you may want to wait a few days before upgrading.
    Lightroom (cloud-based service) has export options (such as TIFF format, renaming and color space), custom sort order on the desktop, copy/paste to multiple photos on iOS and more.
    The Missing FAQ and Edit Like a Pro eBooks are already updated for the changes.
  • Are you using the cloud-based Lightroom apps for Windows, Mac, iOS, Android, Apple TV and Web? Then you'll love my new book, Adobe Lightroom - Edit Like a Pro!

    You'll learn how to use the Lightroom cloud ecosystem to organize, edit and share your photos. You'll also come to understand the thought processes used by professional photographers when they're editing their own photos, so you can transform your photos quickly and easily. And better still, the eBooks are updated for every release, so it's always up to date.

Hi there,

I'm new to the forum and new to Lightroom. Is there a performance advantage to selecting the option to save all smart previews locally? Offline editing advantages? If so, a brief why explanation would help me. Are there any cons outside of space availability?

Hi mstatdfield, welcome to the forum! As you guessed, it's primarily for offline editing, but does also help with performance because the photos are cached locally instead of having to download from the cloud as you try to view them. The only con is space.

I think there is one other “con” although a trivial one. Smart Previews generated on import take additional CPU cycles and can be seen to slow down the import. As for generating up to date Smart previews, there is a trade off. Having a ready to edit Smart preview or needing to generate an editable RGB file from the original each time you need to edit that file. While both detract from performance, Smart previews are generated for every image whether it gets redeveloped or not, while the preparation lag for bringing up an image into develop without a Smart Preview is short and only fo that one image at a time.

Depends on the size of the raw file and the machine you operate on. For me, fast processing of hundreds of raw images, having SP built and ticking for them to be used instead of Originals makes a massive difference (I process images sequentially and build a SP for all of them first)

Cletus, I think you're getting the Lightroom versions mixed up....the OP was talking about downloading SPs from the cloud to be stored locally by Lightroom "Cloudy", you appear to be talking about use of SPs in Classic.

Yes, you are correct. Oh, how I long for the days when there was only one “Lightroom”.

Thanks for the insights. Makes me wonder, what would the pros/cons of storing the originals locally?

Pros: Redundancy, Offline access
Cons: Disk space, Performance (no duplication of maintaining originals?)

I'm using LR Cloudy primarily to have a unified gallery between my phone, my wife's phone, and my DSLR. Most of my editing is just cropping, adjusting shadows, and brushing out imperfections. I don't think I'm scratching the surface on a lot of features. Thought I'd give that disclaimer in case it helps you provide direction on what storage local options I should select. I'm leaning towards having all smart previews saved locally, but not originals.

PS Adobe's naming makes finding answers to questions extremely difficult! When you think you find the answer on an existing article or tutorial you end up sorting through answers to Classic. A more unique name for Cloudy would have made for a much easier for people like me to find answers!

Apologies all, I also got mixed up. And it's on the Cloud thread and all!!!

I'd keep a local copy of originals on at least one computer, just in case aliens invade Adobe's computers (well, probably not aliens...). If you have fast internet, I wouldn't worry on other devices. If you store the originals locally, I wouldn't worry about the smart previews.
