Adobe today announced a “massive update” to its Camera Profiles feature. It’s now simply known as Profiles, and the way they’re accessed has been redesigned.
In Lightroom Classic and Adobe Camera Raw, profiles have been moved from the Camera Calibration panel to the Basic Panel. The feature has also been added to Lightroom CC at the top of the edit panel.
First off, here’s Adobe’s explanation for what profiles are and what they do:
In photography and digital imaging, the term “profile” can mean many different things. There are color profiles, display profiles, printer profiles, working profiles, and so on. Within ACR and Lightroom, a profile is used to render your photograph, converting it from raw camera information into the colors and tones that we see.
For raw photographs, we build profiles for nearly every camera make and model we support (our DNG format enables camera manufacturers to build their own profiles). Our profiles incorporate deep imaging science and take into consideration the colors of the filters used on top of the sensors (the array of red, green, and blue filters that help an otherwise colorblind sensor “see” the colorful world around us), the specific sensitivity of the sensor used, the sensor’s characteristics in different lighting conditions and with different ISO values to interpret the digital 1s and 0s into images inside Adobe photography products.
For non-raw photographs (like JPEGs and TIFFs), a profile isn’t needed to render the photo, as all of the rendering was done already (either in another raw processor or within the camera itself). However, profiles can be used for creative purposes to change the look and feel of the photo.
