APRIL 2018: This action no longer works and the links to it have been removed. You can batch-convert raw files to DNG with Adobe’s DNG Converter (currently at version 9.12.1), or when importing images into Lightroom (version 6 and Classic), if that is your primary image editor.
For step-by-step instructions on batch-converting Raw files with DNG Converter, see this more recent post on Complete Digital Photography; this process is required if you are using Lightroom 6 (the last non-subscription version of Lightroom) and get a new camera with raw files that aren’t supported with Lightroom 6.
We still publish a set of Photoshop Automator Actions, which has been updated for Photoshop CC 2018. You can find out more at our sister site, RobotPhotoshop.com.
Adobe’s Digital Negative Specification, or DNG format, provides an open standard for the storage of raw camera data. However, since few cameras can store directly into Digital Negative format, if you want to take advantage of DNG, you first need to convert your existing raw files to DNG format using the Adobe DNG Converter. Mac users running OS X 10.4 (“Tiger”) or later can ease their conversion tasks using this Automator action, which lets you batch process your DNG conversions, as well as include DNG conversion in a more complex image processing pipeline. This updated version adds Leopard support as well as the ability to convert Sony SR2 files.
For photographers who shoot raw, DNG offers several important advantages over proprietary formats: it’s open source, so any software or hardware vendor can support it; it won’t vanish if any particular company goes out of business; and it includes support for all raw conversion metadata, making for a more efficient, all-in-one, raw format/metadata file.
Automator, meanwhile, is an excellent workflow automation tool which allows you to create applets that automatically manage your post-production pipeline. Read more »
