I'd heard about the OnOne DSLR Remote software for the iPhone, but found it hard to believe. I have a really inexpensive cell phone service and couldn't see going to the iPhone's large monthly bills even if this iPhone app DID work.
As some of you know, I sometimes use my camera on a 12' boom, and I'm just guessing at to what it's "seeing," so this remote view would be wonderful if it worked. I then heard that the software worked equally well with the iPod Touch! No monthly bills, a PDA, an MP3 player, and a portable camera remote?
I bought a refurbished iPod Touch and downloaded the $20 app. As you can see, it works!
Take a look at the preview image on the iPod. It's just what the camera's seeing. With the iPod in this vertical orientation, I can adjust f-stop, shutter speed, ISO, color balance, etc, etc. In the horizontal orientation, the image fills most of the screen. Here my thumb's on the FIRE button, taking this photo.
The one drawback is that the camera has to be wired to a computer. Here it's wired to my laptop which has the free server software installed. Now all I have to do is "teach" my laptop to continue working when shut, then I'll close it and put it in a mesh laundry bag (so it doesn't overheat) and hang it from a shoulder harness. I'll put the iPod Touch on a small bracket mounted to the harness and I'll be able to see what my camera's seeing from out on its boom!
This only works with certain cameras, and of those, only the ones which can already do Live View will work as a remote viewfinder. Even if I didn't have live view, I'd enjoy seeing what the camera had just shot instead of bringing it down to the ground to check the LCD on the camera. I'm using it on my Canon 5D Mk II which has Live View.
I had to share this great news with you!
