Hi. Im having trouble with lightroom CC. When i import new pictures grom Sony alfa and try to develop IT lightroom ads some presets by itself. I tried to re install lightroom, reinstalled windows on computer. Nothing helps. It happens not only on this camera. I dont know how to turn IT off but it makes impossible to work with that. Would welcome help.
Your video isn't very clear, but I think it says Embedded Preview at the bottom right of the screen.
This means that you have chosen to use the raw file's embedded jpg preview instead of having Lightroom create its own preview from the raw file on import.
The jpg preview can, depending on the settings you have chosen in the camera, look very different from Lightroom's rendering. So the settings you have chosen on your other cameras are probably closer to Lightroom's rendering.
To stop this from happening, choose any other option than Embedded & Sidecar under File handling > Build Previews in the import dialog.
Alternatively, you can set up Lightroom to use a camera profile that corresponds to the one you're using in the camera rather than it's own default rendering in preferences. (provided that there are Adobe camera profiles for your camera model)
