The D5500 was first supported with ACR 8.8/9.0.
Are you using PS-CS6 or something else?
What OS are you running?
I have Photoshop Elements 11 on a HP Envy windows 8
Photoshop Elements 11 will only utilize up to Camera Raw 7.4. You will either need to upgrade Photoshop Elements or use the free DNG converter provided by Adobe. The latest version of the DNG converter is 9.1.
Thank you I will give this a try first and then if any look into upgrading my Photoshop. Thank you again!
