Quote - for the washed out texture image you can adjust the texture strength to balance the difference

...which will reduce the light cast into the scene in the IDL render.

I've found it easier to just render the scene using a white or coloured ambient  (set to an average of the colours of the image), then re-render the scene with no IDL or lights but with the ambient image set to value 1, and then composit the two renders in an image editor.
