Today’s Question: In trying to test the new dust removal feature in Adobe Camera Raw, I discovered that if I use “Edit in Photoshop” from Lightroom Classic, the files open directly into Photoshop. If I go to Explorer [or Finder] and double-click on the same file, it opens in Camera Raw. Can you explain this?
Tim’s Quick Answer: When you send a raw capture to Photoshop from Lightroom Classic the image is rendered by Lightroom Classic including the adjustments from the Develop module. In other words, what is sent to Photoshop isn’t a raw capture, which is why Camera Raw is not invoked. However, you can still use Camera Raw as a filter in Photoshop.
More Detail: If you open a raw capture directly in Photoshop (including by opening the image from Bridge or through the operating system) the image will automatically be opened in Camera Raw. The same is true for JPEG, HEIC, and TIFF images if you have enabled support for those file types in Camera Raw Preferences. The same is not true for images sent to Photoshop from Camera Raw.
The reason is that when you send a raw capture to Photoshop from Lightroom Classic it is in effect processed by Lightroom Classic so that a fully rendered image is sent rather than a raw capture. Therefore, the image is simply opened in Photoshop without the use of Camera Raw.
However, there’s no need to resort to opening the raw capture directly in Photoshop to get to Camera Raw. You can simply use the Camera Raw filter, which in the current public beta version of Photoshop includes a Dust option for Distraction Removal, along with options to remove Reflections and People.
To use the Camera Raw filter in Photoshop, simply open an image, select the applicable image layer (making a copy or Smart Object if you want to work non-destructively) and then choose Filter > Camera Raw Filter from the menu. You can then choose the Remove tool from the toolbar at the top-right and select the Dust option in the Distraction Removal section.
