Seems to be a similar problem. However the photos are still changed to a different color/exposure even when I go to develop. I do not have any import presets checked, so I am still confused to why I can't have the original photo.
The "original photo" is a JPG produced by the camera use camera-manufacturer raw-conversion algorithms and embedded in the raw file. If you want your photos to look like the camera produces them then use your camera or camera-manufacturer software to produce JPGs.
If you use LR or PS/ACR, you're making adjustments to the raw data using Adobe raw-conversation algorithms. The camera manufacturer and Adobe had no idea what each other are doing.
If the pictures look washed out that is what the raw data looks like. The camera is doing some automatic fixing or you've specified a picture mode with higher contrast than the default. Camera manufacturers work hard on making good JPGs from the raw data. If you're using LR then you're taking the place of the camera manufacturer and have much more control than allowing the camera to do everything. It's a trade-off, ease of use vs more-control.
You can use Auto tone in LR and/or use the Camera xxxxx profiles in the Camera Calibration area to get something closer to the camera conversion.
A simple thing to do is double-click on the Blacks and Whites sliders to have LR automatically compute black and white points. This will probably look better than the default conversion, and you can do it after each other adjustment you make that changes the tone of the image.
