I am a Professional Photographer. I show my work on my iPhone 4S and iPad 3 all the time and I rely on it to impress my customers. I am concerned about the new screen size on the iPhone 5. If it is really true that the screen is going to be 640x1138 pixels, then photographers are gonna be in trouble... Right now, the ratio of the photos from my Canon 1D X is 3:2 (Most Pro Cameras have that ratio). The iPhone 4S 8MP Camera and most consumer pocket cameras have a Ratio of 4:3. Full HD Video (1920x1080) has a Ratio of 16:9 (The same ratio of the future iPhone 5) What does that mean for photographers or people that want to show photos on an iPhone? It means lots of wasted space (huge black borders) and the same actual size displayed photo as a smaller iPhone 4 screen. Of course, double tapping will zoom the image and give you a full screen coverage but with a ratio (16:9) that is not good for either 3:2 or 4:3 photos... To me as a photographer, a really bad thing. Even if Apple changes their camera ratio to a 3:2, there are still 178 pixels of wasted space on the sides of the photos. It will be a great screen for videos but NOT for photos. Look at the attached screen comparison chart to see what I mean.
