2.4.2 and onwards now differ between --capture-image (leaves image on
camera) and --capture-image-and-download (retrieves and deletes image)

Basically, I see two ways to fix the confusion:
1. When --capture-image is used alone (i.e. it would just capture to
memory and not actually save the image) just download it as if -I 1 -F 1
was done.
2. When -capture-image is used alone print a warning message something
like:
Warning: Capture to memory in use. Use interval capture or change
capturetarget to save to disk.


Either way, it would be useful to document this better in the --help
output and the manual page.

Thanks.

The interval capture works fine for the 5900.
The message about it downloading and then seeing no file threw me for
quite a while until I found this bug.
So down to just the problem jjc indicates. A fix could be to use the
interval capture to return the file
to the PC when just --capture-image is set.
Nothing too serious but very confusing to someone new to gphoto2 like me.

we are just storing it virtually if it is named "capt000x.jpg".

reason for this is to get interval capture to work.

to download it in this mode
gphoto2 --capture-image -I 1 -F 1

If the 5900 bug is not the same as this, reopen a new bug.

This is also broken in the same way for a Nikon 5900.

$ gphoto2 --get-config capturetarget
Label: Capture Target

Type: RADIO
Current: Internal RAM
Choice: 0 Internal RAM
Choice: 1 Memory card
$ gphoto2 --set-config capturetarget=1
gphoto2 --capture-image
New file is in location /store_00010001/DCIM/100NCD40/DSC_0003.NEF on the
camera


Okay. That worked.

So, down to one thing I think is an error:
By default "gphoto2 --capture-image" claims that it is storing it to the
card
output:
"New file is in location /store_00010001/capt0000.jpg on the camera"
despite that fact that it is not capturing it to the sd card.

Please try:
gphoto2 --get-config capturetarget

it should have two choices?

Well, the "gphoto2 --capture-image -F 1 -I 1" command does work with the
camera.

"gphoto2 --set-config capturetarget=card" does not work:
gphoto2 --set-config capturetarget=card

*** Error ***
Choice card not found within list of choices.

So, as I see it, there are two bugs:
1. "gphoto2 --set-config capturetarget=card" does not work, despite the
fact that 2.3.1 could capture to a card with the Nikon D40.
2. "gphoto2 --capture-image" claims that it is storing it to the card
output:
"New file is in location /store_00010001/capt0000.jpg on the camera"
despite that fact that it is not capturing it to the sd card.

This means "capturetarget" is set to RAM.

to get the image in one go do:
gphoto2 --capture-image -F 1 -I 1
which will download it.

To save it on the card do;
gphoto2 --set-config capturetarget=card
gphoto2 --capture-image
