I shot some landscapes the other day, i set my color space on my canon 1ds mark3 to landscape, downloaded and went to ACR to process, thats when i noticed the color space was set to adobe standard which was very different.
Those settings (picture styles like 'landscape') have no bearing on raw data, only a camera JPEG and ACR/LR doesn't use Adobe Standard or any DNG profile expect with raw data.
So do i A, process in camera raw and have sharp images that the color is off, or what?
You use the controls and tools in ACR to make the image appear as you desire and sharp. If the color is 'off', it means you have some sliders to move so the color isn't 'off' any longer.
