Hi Lara,
The iPad is great as a promotional tool to showcase your works.
I started to try and import all my photos into my iPad the minute I got it.
But I realised that that is not possible as using the iPad to sync photos from my iMac is an agony. It tries to optimise the photos to fit into the display size of the iPad and it is taking a long time to optimise the photos.
At the present moment, I have about 30,000+ photos and after 2-3 hours of optimising, I gave up. Had to reorganise my folders and select only the essential ones.
The iPad is definitely better at showing the client the full image on a 9.7" screen as opposed to a 3" LCD.
Have you got the camera connection kit? Was trying to get it when my wife bought the iPad for me, but it wasn't available at the store.
Were you using a Lensbaby, Lomo or T/S lens for the above shot ? DOF plane seems different from a normal lens.
