Excellent example. Just what I was looking for.So I guess the message is that the iPhone can do a digital zoom on a subject in the distance, but the resolution will be so low that the image will be very grainy?
There are two problems with the iPhone:1. The scene (i.e. the boat) only extends to about 100 pixels for the iPhone rather than 2,000 odd for the DSLR picture2. There is much more noise on the iPhone's image than the DSLR. This is due to the sensor being smaller so the is less light being received per pixel.
