Remote release:

if you want to release the shutter of your D-SLR remotely, you will have to buy one of those expensive electric cable releases. These cost a lot, especially if you want some useful features such as timers, intervalometers etc. to be built into the release. Don’t worry any more as there are several apps that allow you to use your smartphone as a sophisticated cable release with all the features mentioned. The connection between your smartphone and your camera will be through the USB port. You will be required (most probably) to get a USB OTG (on the go) cable. Your smartphone manufacturer will offer this. This will help you connect your smartphone to your camera through the USB cable supplied by your camera manufacturer. I have left the most important and useful app as the grand finale! Here it is:

Live-view and remote control:

One step ahead of a simple release is the full blown remote operation. Most of these remote control apps are not free, but they are not very expensive either. First connect your smartphone to the camera through a USB port (as already described in the previous section, see also Picture RC1). Now, the app will help you to control all the major parameters such as shutter speed, aperture, ISO, White Balance etc., with the help of menus that can be seen on the smartphone screen (Picture RC2). You can of course, release the shutter too from the phone. If your camera supports live-view, you can see what your camera sees on the display of your smartphone screen (Picture RC3).
