One of the big advantages of any phone-camera is that you pretty much always have it with you. If it is an iPhone, you also have the option of doing some really fancy stuff: HDR, Panorama, and Postprocessing in any number of creative apps.

This was taken with in the parking lot of our local grocery store on an after-supper milk run using the iPhone 4 and Pro HDR in manual mode (which allows you to pick your own light and dark points).  It was processed right on the iPhone in PhotoWizard using Auto Contrast, Unsharpmask, and Auto Color (enhance) filters, and uploaded to SmugMug with SmugShot.

Pretty good for a phone.

I did try cropping out the car and cart rack, and I messed with the Wide Angle distortion filter in PhotoFX, but I decided I actually like the context of the parking lot here, and PhotoFX introduced as much distortion as it cured. Sometimes it is good to leave well enough alone.
