Does anyone know why my old raw files from the xsi opened great in Lighroom 4 and yet shots in raw on my canon 70D will not open in Lightroom 4. I am not sure this is relevant but I have 8.3 adobe raw converter.
The 70D requires at least Lightroom 5.2. Having the Camera Raw plug-in will not help you as far as Lightroom is concerned because it isn't used by Lightroom. All of the raw technology is in the program itself. You will either have to upgrade and purchase Lightroom 5 or use the DNG converter to create DNG copies that you can use in Lightroom 4. Another alternative would be to generate TIF copies using the DPP software that was included with the camera. Those TIF files can be imported into Lightroom.
thanks so much, yes I thought so, but wanted confirmation.
