Mike,
Lots of folks like the Cessnas for taking photographs as the window can be latched in the up position (make sure the latch is fully functional or window is alternately secured as if the window slips you'll end up with either a busted side window or busted camera lens). Personally, I think most people use the Cessnas 'cause they are what is most available. Between the strut and the wing root on the relatively long high wing you have to move the camera a lot to frame the shot.
I really like the Grumman aircraft for taking pictures from the air. You can slide the canopy open during flight. The short wing can easily be moved out of the way by banking or slipping the aircraft.
Some advice regardless of what aircraft you use is to bracket your shots. That is, take the picture, change the aperture up 1/2 or 1 f stop(s) take the picture again then change the f stop down 1/2 or 1 stop(s) from where the first picture was taken. You'll use more film but you'll get the picture. The reason I suggest this is that it appears to me that the light meters in many cameras are fooled into taking the wrong reading. I don't know if this is due to tinted plexiglass or shading from the cabin enclosure or a high wing. Some fully automated cameras do have a setting for changing the f stop. Of course, with manual cameras you have complete control and the controls will be easier to manipulate 'cause the camera was designed with that control in mind.
