Hi Jerry Chang,
We have exhausted our work with Leopard Imaging on this issue and they confirmed that they cannot bypass (turn off all features) on the ISP.
To further explain, we want to use the ISP but we are finding that some features such as sharpening are applied to all images that pass through the ISP. We do not want this.
Also, we know what to do with raw images that bypass the ISP but we are hoping to use the ISP in many cases. If we bypass the ISP we will simply go a different route and no longer consider using the TX2.
