The explanition how to use the new enhance option is very vague.
Open the image in Camera Raw.
In the filmstrip, Right-click (Windows)/Control-click (Mac) the image and select Enhance from the context menu.
In camera raw there is no film strip in ACR? I can not even figure out how to ope anything bu a single image in ACR, and there is no film strip there, and no enhance option. I have not used ACR by itself before, LR and PS use it in the background, but in the background there is no enhance option.
