Hmm we use a Canon 350d (XT), or a 20d and a 5d. All Canon Raw sizes are in fact taken full size with no 'in-camera' compression. Can they be resized? Sure! If they are non panorama single image of a bird or tree they can be cropped. But as a part of finalizing the image they have to be saved to another file type.. like an 8 bit jpeg, bmp or 16bit tif. The original Canon .cr2 or Nikon .nef remains unchanged... only the copy is cropped. That is why they call the RAW file a "digital negative". In the case of Canon raw .cr2 file type, the image alterations are contained inside a side car ".xmp". So when you want to see the picture again the .xmp file alterations are implemented when you open the .CR2 file.
Question What is a 50% Tif?
I would guess most real estate VR folks probably do not use RAW iamges because it adds too much time to the work flow. For those who are working with large business - Raw imaging is probably their only method.
