Unfortunately we do not have the ability to tether your camera to the new Photo RAW 2017. You will need to copy the images from your camera's card and place them onto the local HD or External Drive prior to editing and processing your images in the Photo RAW 2017. Tethering is a common feature request that we may add to future versions of the program.
To submit a feature requisition, please check out of Photo RAW Project page. We will be reviewing all suggestions and including some of these feature requests in future updates to Photo RAW.
