Hello, it's all in the title :
How / where can I donwload the latest version of Camera Raw in order to open my D4s raw pictures ? I actually have Photoshop CS5 on Mac OS 10.9
What is the process too ?
You need at least ACR 8.4, and CS5 is only compatible up to ACR 6.7 so you’ll either need to pay for an upgrade to PS-CS6 or sign up for the cloud to get ACR 8.4.
Or you can use the standalone DNG Converter 8.4 or higher, to create DNGs from your raw files and process those in your older PS/ACR combination. You can get the DNGC 8.4 from here:
