Macworld's iPhone 4 cover shot with an iPhone 4

The main topic of the new Macworld will be iPhone 4. That's why the image of the new iPhone 4 was photographed and post-processed entirely on another iPhone 4. This was done by Peter Belanger.

Shooting and editing only on the iPhone had its challenges. Normally Peter shoots Macworld covers with a Phase One P65+ digital camera, which offers 12 times the resolution of the iPhone 4’s camera. That meant getting an image as close to the size of the Macworld cover as possible, because any cropping would reduce the resolution of the image even further.

For post-processing Peter used two iPhone apps - PhotoForge ($3) to remove green cast and the Resize-Photo ($1) to increase the resolution from 216 dpi to 290 dpi to meet the printing requirements.
