where would I find photos done by a resident from the air
That sounds like an interesting topic! But I'm afraid I need a little more information to try and track down the information you need:
1. You mention he was a resident - a resident of Omaha, Nebraska?
2. Do you know the first name of the photographer? Omaha has far too many 'Millers'!
3. By from the air, I'm assuming he does/did aerial photography. Is he currently doing it now, or was this some time in the past? If it's in the past, when was he most active?
4. Do you know if his photos were published anywhere? Whether in a local newspaper like the Omaha World Herald or in a book, any information would help.
5. Is there a specific picture you're looking for? If so, any description of the picture itself or any landmarks would also be helpful.
Even if we can find out all this information, there is no guarantee we can find anything. But by narrowing it down we'll have a better chance!
