Here's a note on storage. I used Transcend 64 gb cards. Two cards were all that was needed for two weeks' shooting. When I changed cards I backed up to a Colorspace UDMA, which backs up the IQ 180 files but doesn't render them. I didn't carry a computer because of weight limitations.
On the flight back to NY I tried doing a rough edit of the files on one of the cards on the back. I deleted some of the total disasters, defying conventional wisdom to the effect that you should never delete files in the camera. Well the conventional wisdom is still correct. Part way through the process I noted that the back wasn't showing previews of some files - it showed black frames with red x's through them. Not good. I turned the back off and got some sleep.
When I got home I uploaded files from the Colorspace just fine.
Three rules were reinforced:
1. ALWAYS, I MEAN ALWAYS BACKUP. HAVE A STRATEGY WHEN YOU ARE TRAVELING TO HAVE TWO COPIES OF EVERY FILE STORED SEPARATELY.
2. NEVER DELETE FILES IN THE CAMERA.
3. THE MAIN RISK FOR CORRUPTED/LOST FILES IS OPERATOR STUPIDITY, NOT FAILURE OF A CARD. MANAGE YOUR WORKFLOW TO MINIMIZE THE RISK OF YOUR OWN MISTAKES.
It would be really helpful in dealing the many "polaroid proofs" that are generated in trial and error focus/exposure/composition if Phase would implement the color coding scheme that's available in C1 in the back's firmware.
