Is there a way to remove the dark background from the layer under the color photo I am printing?

I'm very, very new to InDesign (about 24 hours). I'm designing a hard copy book dust jacket. The back layer of the InDesign file is dark blue, and the color .jpg image (photo of author)  in the layer above the dark blue background looks muddier and darker than it should be when I do a test printing at FedEx Office. 

I think the problem is not the image, which looks better printed on its own, on white paper. How do I remove the dark blue from the part of the background layer that rests directly under the photo?

Unless you've set the photo to overprint in the Attributes Panel (Window > Output > Attributes) it will automatically knock out whatever is behind it.

As far as I can tell it is impossible to set an image to overprint in the interface, no matter what tricks I tried, let alone accidentally, so more likely your problem is either with the image itself, or the quality of the printer at FedEx. Accurately judging color on screen requires a properly calibratred and profiled monitor, and good monitors will often cost more than the computer these days.

Thanks so much for clarifying this.
