Photographs with DSLR using your smartphone

The multi-tasking monster in your pocket is far more powerful than you think. Some intelligent apps, a few hardware additions, and you could convert your phone to do just about anything you can possibly imagine.

If you have a compatible Canon or Nikon DSLR, the DSLR Camera Remote app for iPad/iPhone ($9.99- $24.99) can activate the camera’s shutter, record video, adjust exposure, bracketing, ISO, white balance, etc. Connect your camera to a computer using USB or Wi-Fi, install the free DSLR Camera Remote Server application and get the app on your iOS device.

Extra : Infrared Remote Controls using your smartphone

No, your phone doesn’t have an infrared emitter, but with Griffi n’s Beacon ($69.99, excluding shipping and customs), it sure acts like it does. The sleek, stone-like device syncs with your smartphone via Bluetooth. Download the free iOS app called Dijit Universal Remote and configure your appliances with the app. Your phone will operate anything controlled by an infrared remote – TV, AC, heater, etc. What about dongles and cords? Not required. Click a button in the app, the phone sends a signal to the Beacon, which converts it into an infrared signal and transmits it to the appliance.
