I have been looking at a way to review images in real-time on a larger screen than the 3" on camera display. I purchased the iPad a while back and have been only impressed with it's capabilities so far. I bought the Apple iPad Camera Connection Kit and was very impressed with how it converted RAW into jpeg in real-time during upload. However, this still required me to stop shooting and break out the connection kit and cables to upload the images. It was still a way away from my nirvana of real-time image transfer while I shoot.
I started doing a lot of research online into options to use the iPad as a way of reviewing images on a larger screen in real-time and came accross a thread about using Eye-Fi SD cards and a iPad app called ShutterSnitch. While there are options to use a CF card convertor for the Wi-Fi enabled SD cards, I prefer to stick to my current CF cards. The solution also required the iPad to be jailbroken and for me that was not an option.
After more research, I saw someone had had success linking a WFT unit to the iPad direct without the need for jail breaking it, so I started running my own test to see if it met my needs also.
iPad (Wi-Fi or 3G)
Canon 5D Mk II
WFT-4E II A
heap load of patience
After much trial and error I found this to be the best way to setup the WFT and iPad to make it work.
Setup the WFT first otherwise you will have a load of issues on your hands. I used the following settings:
Communication Mode = FTP Trans.
Automatic Transfer = Enable
Transfer type/size = JPEG Only
Transfer with SET = Enable
LAN Type = Wireless
IP Address set. = Maual Setting
DNS Server = Disable
IP Address = 192.168.1.1
Subnet Mask = 255.255.255.0
Gateway = 192.168.1.1
Target Server = Address = 192.168.1.2 Port No. = 26000
Login Password = Login Name = snitch Password = <pick a password you will remember>
Directory Structure = Default
Passive Mode = Disable
SSID = WFT adhoc
Advanced Settings = Conn. Method = Adhoc 11g Channel = 4 (more on this later) Encryption = none
Open General Settings and navigate to Wireless connections.
With the WFT and 5D Mk II switched on (important!!) connect to WFT Adhoc.
Click on the blue arrow to get to the connection settings.
Static IP Address
IP Address = 192.168.1.2
Subnet Mask = 255.255.255.0
Gateway = 192.168.1.2
Leave everything else blank
On first launch you will be asked to setup ShutterSnitch.
Password = <Password you setup earlier on the WFT>
Login as Super Admin and create a collection
You should now be ready to start sending images remotely from the camera to the iPad.
Issues to date
I have experienced issues with slow transferring of images and even complete dropout between devices. This was driving me crazy to begin with until I looked a little further into the WFT setup and found it was using AUTO for the Wireless channel. The issue seemed to get worse when I took a trip to Funan and tried to connect there. Given all the wireless networks floating around my apartment and Funan, I decided it was a channel issue and set the channel to 4 and the problem mostly disappeared.
I have my 5D Mk II setup to capture RAW and small JPEG and the WFT to transmit the JPEG only. I did some testing using RAW images and found it took far too long to transmit the images to the iPad (30+ seconds each).
I will be giving it a full field test tomorrow afternoon and will report back on how I got on
In the meantime, I will post a short clip showing the WFT and iPad in operation shortly.
