The Nikon D4S is a brand new camera which has just been added by Adobe to Camera Raw 8.4.
8.4 has not yet been finally released but you can download and install a pre-release copy for CS6 and CC (it is not compatible with CS5 and earlier)
Thank you so much. I uploaded the plug in and then dragged the new RAW photo to the Photoshop CC I am subscribing (or what they call it ) from newest Photoshop version.
It opened and I was able to save as a JPEG also.
There was a warning about a BETA something, I did not understand, but I assume this will work unti Abobe catches up to the new camera.
I was hanging on to my NIkon D3s until I knew for sure I could download the D4s RAW files to Photoshop, so I appreciate your help so much!
