I love it!
I was debating between the iPhone 4 or 4s. I am so glad I selected the phone with the better camera.
In good lighting, the image quality is amazing. I then edit in camera using Snapseed- a Google app for editing images.
I keep it pretty simple-
boost the whites, contrast, saturation, and tweak the white balance. All those edits happen in about 5 seconds.
Then I increase Sharpness and usually add a little center focus. Another 5 seconds.
I am taking more pictures which I Love.
Food images go on an amazing app called Foodspotting.
Everything either on Tumbler, Twitter, or my blog. All from the phone.
I am one happy hombre.
