This thread has been tempting me all along, as it combines my 2 favorite hobbies, ddf and photography.
Note: I prefer a wired remote over wireless. With wireless you need to aim it and be infront of the camera, + you need to listen out for the shutter to know it worked. With wired, ur camera can be in any position, and are much more reliable. Either way they are a few dollars each online, so might as well go for 1 of each.
Also, if your phone has built in ir (eg: s4 and htc one do) you can get a remote app.
