I have opened an Image in Adobe Camera Raw and I am trying to apply lens corrections. When I go to the Optics tab, there is no selection to apply lens corrections, the only available selections I have are a 'distortion' and 'vignette' slider and a defringe tab.
Can someone please advise if there is something I need to load, I've scoured everywhere and haven't been able to turn up any information yet.
Your using the Camera Raw Filter accessed from inside photoshop proper by going to Filter>Camera Raw
Filter, which doesn't have the full set of features that Camera Raw proper has.
In order to get the Lens Correction Options under Optics you need to access Camera Raw by using File>Open in photoshop and pointing to a camera raw file or from Bridge by right clicking a image thumbnail and clicking Open in Camera Raw.
