Most of what I am finding about about using the iPhone as a viewer for DSLRs such as the onOne software requires a computer in the mix. This is not practical on location like when you are shooting a wedding.
Confirmed. I experimented with eye-fi in conjunction with my iPad exactly for the purpose of chimping wirelessly on a big bright screen. It seemed to work pretty well shooting small jpgs, but that's about it. The concept has potential, but some issues need to be worked out. If anyone has done this successfully, I'd like to hear their particulars.
Oh, the eye-fi card and the iPhone/iPad need to be connected via a wi-fi network, of course. The card can't connect directly to the device. Just to clarify what is probably obvious to most.
Using an iJOB's screen, whether a phone or a pad, likely will not be able to have proper calibration, and some of the other vitals, suggested by folks like Ric to manage onsite capture, unless it's simply for run and gun viewing, slightly larger than the LCD panel.
I did see the latest pitch commercial last night about the phone using the sharpest screen to date, so perhaps now?
Although as I do not use Apple's appliances, so that may be wrong.
I do know they have clap board apps, and room analyzers for audio techs, so anything is possible.
Thank you Four Eighty and Robman. These look like two really good options.
I think a full time large screen perched on top of the camera during a wedding shoot might be more than I want, however. I wanted to find something that uses the high quality of the iPhone 4 screen so I can quickly check a few key shots whenever I get a breather. Since I am carrying the phone in my pocket anyway, I was hoping I could find another good use for it.
