In the field, in this case was the Oakland A's stadium. I usually find it difficult to gauge resolution performance with landscape, nature or portrait photos. Human faces just on the edge of resolving power definitely make a noticeable impression.
It seems this little fixed (permanently affixed zoom) lens camera will provide reasonable 11"x14" prints, and I may need to limit it to 8"x12" for close up viewing with fine detail. I did recently make a couple prints at around 16"x24" that turned out very well after up-rezing, but one was a simple head and shoulders portrait, and the other was an abstract landscape. At least with the techniques I am aware of, that seems to be about the limit for this 12mp sensor.
My blog post has more detail regarding the processing, but here are 100% crops before and after increasing resolution to about the maximum I would normally attempt.
