Hybrid forms in media can literally be anything where two mediums come together, for example Lev Manovich said:
A music video may use live action while also employing typography and a variety of transitions done with computer graphics.
In that example three forms have come together, footage, type and graphics. Or it could be two photographs coming together.
I have found one photographer who specialises in panoramas and gigapixel images. Henry Stuart also takes photos that have photos within them so you can see the details in closer detail. Usually the photos are commissioned by someone. He has his own company Spherical Images where also you can see more of his work and also he has placed some of the photos on an interactive map.
