Creating seamless mosaic with aerial photography tiles

I have some aerial photography captured using a film camera, not digital.
As a result the image tiles I have all have a black border around them with various details on the photography.

What I would like to do is remove these black borders so that I can seamlessly mosaic the overlapping tiles together.

Does anyone know how this might be possible?  The 'nodata' areas have already been made transparent, and do not include the black borders.

What you can do will depend on the Version/license level of ArcGIS for Desktop you are using ...

Are you using a Mosaic Dataset for this task?
Did you probably store the data as lossy JPEGs and now the "no-Data" to "Data" borders have started "bleeding"?

If you use a Mosaic dataset you could either extend the no-Data definition to include some of the "bleeding" OR you could use the "Build Footprints" Tool and just shrink your image footprints (seems they have a lot of overlap - so this shouldnt hurt) ...

So please check out these options first ...
