Lightroom: Slow Develop Module? Increase RAW Cache

While I can’t say this Adobe Lightroom cache optimization tip did all that much to increase speed for me, I recognize the benefits could be workflow dependent. By default (at least for me), Adobe Lightroom’s RAW cache is configured for 1GB. But, if you have the hard drive space available, why not increase this cache setting? And for an even greater speed boost, if you have a solid state drive (SSD), make sure that is where your cache is located.

Here’s what Adobe has to say.

Every time you view or edit raw images in the Develop module, Lightroom generates up-to-date, high-quality previews. It uses the original image data as its foundation, and then updates the preview for any processing or adjustments that have been applied. The process is a little faster if the original image data is in the Camera Raw cache. Lightroom checks the cache for the original image data and can skip early stage processing if the image data is cached. (Adobe Lightroom – Optimize performance)

To change the cache value (and location), go to Preferences (Edit menu on Windows / Lightroom menu on Mac), then click on the File Handling tab. Near the bottom there is a section called Camera Raw Cache Settings.


Bump up the Maximum Size to whatever value your free drive space can reasonably handle. And change the Location for the cache to an SSD (if you have one available with enough free space). On my MacBook Air, I bumped the cache up to 10GB, but if free space allows, you might want to consider 20GB, 50GB, or more, especially if you have a lot of photos (tens or hundreds of thousands) in your catalog.

Adobe Lightroom: How To Select Multiple Photos For Import Without Clicking Each Checkbox

Adobe Lightroom is a fantastic darkroom editor and photo organizing application for photographers who want to spend more time taking photos instead of sitting at a computer editing them. And the workflow in Lightroom is mostly straightforward, but something that has always bugged me is the Import screen. Why is it so limited?

When you launch the Import screen and point it to a folder location, it defaults to selecting every image in that location. Luckily there is a “New Photos” feature for importing new photos not already imported into Lightroom. That one feature might be good enough for most people. Also, don’t forget about the “Don’t Import Suspected Duplicates” checkbox on the right-hand side of the Import screen, that can be useful as well.

But for me, I only want to import the best of the best. I know some use Lightroom to catalog and organize every single photo they take, but for me, Lightroom is a way to catalog and organize only the shots I think I “might” publicly display some day. In this scenario, it would seem you have to check each little checkbox to import only the photos you want. But there happens to be a slightly quicker way to do this.

Below are the instructions to easily select multiple photos for import into Lightroom.

  • Click the Import button
  • Click the “Uncheck All” button on the Import screen.
  • Now you need to figure out if the photos you want to import are randomly scattered or contiguous and follow one of the two procedures below.


  • On a PC use CTRL – click, on a Mac use Command – click. Do this anywhere on each photo you want to import. It will highlight the box (thumbnail) of each photo, but it will not put a check in the checkbox.
  • Now that you have all your photos selected, all you need to do is click the little checkbox on one of those selected photos (it doesn’t matter which one) and the checkbox will be checked on all selected photos. It’s a little weird, but hey, it works.
  • Click Import.


  • If all the photos you want to import are contiguous (all next to each other), then instead of CTRL – clicking or Command – clicking each photo you can select them all with two clicks.
  • Click the first photo using CTRL – click (or “Command – click”)
  • Click the last photo using SHIFT – CTRL – click (or “SHIFT – Command – click”).
  • Now click the little checkbox on one of the selected photos (it doesn’t matter which one).
  • Click Import.

Again, a little weird, but I think this helps the workflow just a bit compared to clicking that little checkbox on every single photo each time you import a new set.
