Guillermo Amaral shows how to make your own WiFi Canon DSLR Remote:

Having a tripod with you is not always all you need in order to take sharp, good looking pictures. Sometimes in low light conditions, your hand pressing down on the shutter trigger can make the image come out blurry.

So why not mix the power of the ESP8266 with a convenience of a shutter control? That way you could take photos while you’re chilling watching Netflix.
