The develop tab allows you to tweak those settings, but Adobe also reverse engineers these files to try to create something you’d like as a starting point for your editing process (in the Camera Calibration section – see the “Process” option). Lightroom uses Adobe Camera RAW (ACR) to convert your raw data in a CR2 file into something you can see and use. As a result, you’ll often fine that the in-camera RAW processing is very different from software processing – especially if the software is getting updated regularly. This raw processing is burned into the firmware of your camera and it will only get updated if something significant warrants a change. Even if you “only shoot raw” you see this image as the thumbnail to your RAW file and it’s the data that the camera’s histogram that you see is based on. This is when the raw data is converted in-camera and applies all of the editing settings like color space, picture style, white balance, etc… to give you the image you see on the rear LCD panel of your camera. In-Camera JPEG (downsized in Photoshop,watermarked by Zenfolio) If you haven’t done this exercise on your own already, I’d encourage you to do so! Default in-camera JPEG While this article is Canon specific the same concepts apply to any camera that creates a RAW image that is supported by computer based software and/or Adobe products. This is actually an exercise I do time to time anyway because as software and firmware gets updated, the processing changes often yield different results (not always for the better). To make things more interesting, Canon actually has two versions of its Digital Photo Professional (DPP) software floating around for legacy reasons, so I was curious as to the result I’d get using what amounts various different conversion techniques.
A reader was recently asking me about RAW vs JPEG for a Canon workflow and in the process of replying to those series of emails, I had an ADD moment.įor fun I started comparing the RAW conversion of a Canon CR2 raw file using the latest RAW conversion software from Adobe and Canon as of November 3, 2015.
