I have been thoroughly blown away with the abilities of my little iPhone 4S.
The image to the right links to my iPhone 4s Gallery on Google+. You can go check out several pretty darned good images. The sensor is an eight megapixel sensor, and it has one of the best len’s systems in a phone camera around.
There are a couple cool things about the iPhone 4S camera. The first is that it can be set to shoot HDR as a default. That setting gives you two slightly differently exposed images to play with. … The second cool feature, and I think it is an amazing ability, is that your headphone volume control works as a cable release. … That is cool.
But that is just stuff out of the box. The iPhone also runs other software. I have over 40 applications for enhancing the photos shot on my iPhone.
Sometimes, very few sometimes but still some times, I will only carry my iPhone as a camera.
