Tethered mode with canon 60D problem

Hello,

I'm experimenting with the Tethered Photograph mode.

It's great!

However, there's one detail that's bothering me a bit...

I've set "development parameters" to "without" to get exactly the same photo as the one in my camera.

Except that I've noticed that Lightroom changes colors a bit, removes small details and smoothes out some photos.

When I open the photo on the SD card and compare it with the one saved on lightroom in Tethered mode, there are differences in color and detail.

How can I fix this? I don't want lightroom to modify my photo on its own.

Thanks
