I thought I'd give some of the onboard composition features a go on my 5D3. But I have an odd issue that prevents me from trying one of them.
When I go to Multiple Exposure mode, the camera sort of hangs. It says "Busy.... Please Wait" and never comes out of that screen. The red 'busy' LED on the bottom right never stops flickering, so I assumed it was a full card issue. I have a 50% full 128 GB SD card (which works brilliantly otherwise), and apparently, in Multiple Exposure mode, it needs to access every damn picture, presumably if I want to choose one of those existing shots to be part of an ME composition.
So I put my backup (empty 8GB) card and it snapped right to attention and ME mode was working. But I still prefer to keep all my shots on one card. I transfer and backup militantly, but it's much easier to know where my shots are if they're all in one place.
So how I do avoid the ME mode hanging other than routinely cleaning out my card or swapping in an empty one?
To be fair, this may be a case of me being very stubborn, in that I prefer:
- To shoot with SD (much easier to share shots with non-photogs, I don't shoot video, etc.)
- To keep the last 3-6 months of shots on the card despite having already transferred to a computer
- To not have to swap to another card for ME mode as I'll certainly leave it in there and now have keeper shots on two cards
...so someone may need to tell me that ME mode simply won't fly in that particular environment. But here's hoping someone else found a solution.
