I don't argue about the procedure to delete. It makes sense what you say.
But with the D80 I could delete from the camera through the computer and with the D7000 I can't.
I tried with a memory card reader, and yes, I get the choices I had when importing from the D80.
It seems to me that the D7000 is preventing the option and it may be a good prevention.
Thank you Ernie.
Never, ever let your computer erase data without you first checking that the data is safe. Specifically never use perture (or any other app) to delete the photos from your Camera Card. Disconnect the camera, check the transfer has gone correctly and then use your Camera to Reformat the Card. This has three advantages:
1. You know your data is safe - because you've taken the time to check it.
2. Reformatting the card is much, much faster - takes a couple of seconds
3. Reformatting also refreshes the Directory Structure on the Card, helping prevent issues with the card and prolonging its life.
Why shouldn't you let the computer do the erasing?
Do you know exactly what your computer is doing when it erases the files? Will it do exactly what your camera is expecting if it were deleting them? Probably not.
Mac OS likes to put things in the trash when you delete them, and then your flash card would then not actually regain any space. Rather it would have new directories and new files for managing the trash.
In short, your camera will make sure the card is exactly like it wants it when it formats it.
Thanks. Just to double-check. Sometimes I may not want to import all the pictures on my card; only some of them to work on processing. In this case, I do not want to reformat the card yet.
You are saying, even in this case, I should select and delete the individual photo files in the camera and not through the computer or Aperture correct?
There are two common protocols used to connect digital cameras to your computer. The D7000 is apparently using Picture Transfer Protocol (PTP). This protocol is abstracted from the actual file structure on the flash card so the computer does not have access to delete files. It only provides the communication necessary to copy the files from the camera.
The other protocol is called Mass Storage Class (MSC). Using this protocol the computer has full access to the files on the flash card.
With PTP, Aperture will not be able to delete images on the flash card and therefore won't provide the option. When you put the card in a card reader, MSC is used and all options are available.
Some cameras are able to switch between the two modes. Check your manual or peruse the camera's menus to see if it can be changed.
