Hi Folks: This post also started life as a response to a question asked by a friend, and when it got to a couple of thousand characters I thought I should add some images and post it here. This topic has been covered before by others and to some extent by us. As a prerequisite to this, if you don’t understand what parametric editing is I encourage you to read this first: Lightroom History, Snapshots and Virtual Copies. The basic Lightroom workflow is to import images (associate the image file locations with Lightroom), change the images (by adding metadata, raw conversion, post processing, etc.) and then export the images. Exporting can be done via prints (either to paper or to print as jpg), books, slideshows, web galleries, uploading to publish services (Flickr, Smugmug and the like) or by saving the image(s) as new files. Each of those is worth a blog post in itself; this one is focused on exporting images from Lightroom as files using the Export window. One of the advantages of Lightroom is that multiple images can be exported in one batch, although if one is exporting a lot of images it’s best to break the export process into two halves; this uses Lightroom’s memory allocation more efficiently.

Lightroom History, Snapshots and Virtual Copies
Hi Folks:
I was thinking I should subtitle this post, “Where is the Save button in Lightroom?” because I see that question pop up on social media from time to time and that’s really the basis for this post. The short answer is: There isn’t one. A slightly longer answer is: There isn’t one because Lightroom doesn’t need one. Basically, when you open a file in most computer programs – whether it be MS Word, Photoshop or TurboTax for your income tax – and you make a change, you’re altering the file you have open. In order to keep those changes, you need to save the file by either overwriting the original file or creating a second copy (Save As…) Now Lightroom is essentially a database program, so when you import an image into Lightroom what you’re doing is referencing wherever the image is stored on your hard drive or other device. Lightroom creates a line in its database that says, “This image is located here.” From that reference Lightroom creates its own preview images and works with those previews. When you export an image from Lightroom what it does is to take the information from the originally referenced image file, optimize and add in the changes that you’ve made in Lightroom and create a new image file based on the original image, the changes you’ve made and the export parameters you’ve set. If you’re working with a rendered image file (.jpg, .tif, .psd, etc.) technically you can export an image to the same folder as the original referenced image and tell Lightroom to overwrite the original image, but that’s rather missing the point of the entire ‘non-destructive’ pipeline. There are pros and cons to both pixel editing and parametric (non-destructive) editing and a place for each, but this isn’t the place for that discussion.
