Input resolution vs. output resolution?
« on: June 03, 2012, 11:12:47 PM »
Having some brainstorming regarding aerial mapping. If I have raw aerial photos in let's say 5cm/px, would maximum output resolution of the ortho be the same or less? After some intensive reading some sources claim that 5cm/px photos would produce 20cm/px orthos (not with PS but with traditional software). Any thoughts on this?

I didn't test this yet but I'm pretty sure that it is nonsense to believe, the resolution would get worse, just because it is RAW. The main purpose of using the RAW format in photography is being able to change white balance, color dynamic and other characteristics of the picture after making it. The resolution doesn't change, compared to JPEG.
If you really wanted to alter the white balance, make sure that you do it equally with all pictures. I see no reason to use RAW, as the aesthetic requirements are very limited in aerial photography.
