I am not a professional wedding photographer but I did take photos at my niece's wedding earlier this year and the following is what I had done:
Unless I want to be a spyier, WHY do I want to operate the camera through a cell phone To understand and use any feature of a camera (including WiFi linking 6D with a smartphone), one needs imagination ... the first prerequisite of any photographer.
As a wedding photographer, how do you compose your shots when your camera is already on the tripod and you operate through a phone from distance?
I used 2 cameras, a 5D MK III handheld and a 60D on a tripod. At our Church the parish priest does not allow photographers to come behind him (while the couple are facing him) during Mass, offertory and other Catholic rituals (which goes on for about 90 minutes). So I got the priest's approval to set a tripod (with my 60D) discreetly placed behind him. I used a 10 inch Asus Iconia tablet connected to my 60D with a 20 foot USB cable (running under the church carpet) and remotely triggered the camera with an android program called "RYC USB Pro". I chose a wide angle lens so I could change the AF to capture the couples expressions and sometimes the audience expressions. I took over two dozen memorable photos the professional photographer (who was hired to do the wedding photography) could not capture because the priest would not allow him to be at certain places. I would have preferred if it was totally wireless, like the WiFi feature on 6D, so I didn't have to worry about someone tripping on exposed parts of the USB cable.
Granted that the WiFi feature may not always be ideal for every single situation but everything has a time and place. But a little imagination wouldn't hurt. Sometimes I wonder what Adam Ansel and other great photographers before him would have thought of all the immature cribbing that goes on these days about every little feature on a camera that someone does not use or like. I plan to sell my 60D and get the 6D in about 2 or 3 months time because of the WiFi feature and of course the full frame advantage ... I can already imagine myself using my iPhone strapped to my hand (facing towards me) while I am taking photos above a crowd or placing the 6D near a bird nest and remotely triggering the camera from a distance ... so many possibilities, only if we are willing to use some IMAGINATION! IMAGINATION! IMAGINATION!
Again....this type of shootings are use in "spying", without compositions. Let me guess, you do composition in PP with crop.
I tend to agree with Rienz. Anything is better than nothing. Another example. Having a camera on a pole where you can control composition but can't set manually the exposure or focus is just one of WIFI's uses. Granted you can do this with more sophisticated accessories but WIFI just makes them easier. As Rienz said, it's just about imagination. You have it, use it. Tools are there to be utilized. Only your imagination limits you.
How about sending your camera underneath a remote helicopter and flying it while remotely controlling exposure and focus? I agree, it's too dumb because it's too risky and expensive to do. But we know that soon, there will somebody crazy enough to do it.
Mount a 6D on tripod to capture an ave Joe's shot doesn't require much imagination.
If you just thought about DSLR on Heli.....you little behind. Guess what kinda of DSLR on that heli? I'll give you a hint = NOT 6D, a cheap $200 DSLR that I bought on CL without WiFi....use your imagination
So does this disprove the usability of a WIFI in 6D? I think you only gave an alternative. And guess what, if this is the limit of your imagination, then we can't say anything anymore. In the meantime, I strongly oppose limiting ourselves with these kind of shots. Imagination of a photographer should be boundless. You can't put a limit of what you can do. When you do that then that's the time you stop growing. As artists, we have to think and take all perspectives.
Here's something where you can remote control pan and tilt head. (This is just experimental but certainly have the potential.) Add to this the possibility of remote controlling focus and exposure of your camera, you have a very good camera system where you can put it anywhere. It can give you different perspectives aside from those hard-to-get shots and it has all the FULL FRAME
goodness of the 6D. You can even preview
your shots before taking it.http://www.instructables.com/id/Remote-Controlled-Pan-and-Tilt-Head/
