to not be a mount point under /run, where is it mounted in Fedora 20, so
that I can point dolphin (which is what should be launched from the
'Open with File Manager' prompt, not Konqueror) at the mount point
rather than having to manually type Camera:/ into the address bar.

Thankyou for the links. I looked at those links which gave me a lot more
information that I didn't know about. Unfortunately the documentation on
libphoto2 seems to potentially be self conflicting. The list of cameras
that libphoto2 supports seems to have my Nikon D3100 listed, but the
list of cameras and how they are supported under Unix does not appear to
list my camera.
Following Cameron's email I checked the mount list which seems to
indicate there is no mount point, which also coincides with the
available device interface in the system tray not being able to unmount
the camera before disconnection.
Also now that I have changed to application preference order in the
properties of the folder displayed by dolphin, whenever I select 'Open
with File Manager' at device detection time the process correctly
launched dolphin to display the contents, whereas yesterday when
konqueror was the default application, manually pointing dolphin at
Camera:/ would not display the contents of the camera because dolphin
was trying to treat the camera as a usb device and couldn't acquire the
usb. The only issue with dolphin is it doesn't display the folder name
where the images are stored on the camera as the same name that the
camera says it is, dolphin seems to be putting its own prefix on the
folder name.
Also dolphin seems to be starting at a higher point in the directory
tree for its displays than where Windows starts.
DigiKam now seems be displaying the files on the camera now as well,
whereas yesterday it couldn't either, although digiKam doesn't
understand the raw format files that I am taking with the camera. I
could use jpeg images but that is not as good for image manipulation and
corrections as raw is. I can process these files using the raw interface
to Photoshop Elements and Elements itself, albeit under windows, so not
being able to access these under Linux is not that big a deal to me,
other than the fact that I have to use Windows.

Steve
Does the Nikon D3100 supports USB mass storage mode?
http://goo.gl/7bGFuh
In this respect manual(D3100_EN.pdf) is questionable
http://www.nikonusa.com/en/Nikon-Products/Product/dslr-cameras/D3100.html#tab-ProductDetail-ProductTabs-Support
Therefore you can try this *if* the device supports both - PictBridge(PTP) & USB storage, and they collide:
/etc/modprobe.d/usb_storage-quirks-Nikon_D3100.conf
# Nikon D3100
#
# lsusb
# ID 04b0:0130 Nikon Corp. Coolpix 4600 (ptp)
# ID 04b0:0427 Nikon Corp.
# modinfo -p usb_storage
# ...
# quirks:supplemental list of device IDs and their quirks (string)
#
# 1.
options usb_storage quirks=04b0:0130:i
#
# 2.
# options usb_storage quirks=04b0:0427:i
#
# 3.
# options usb_storage quirks=04b0:0130:i,04b0:0427:i
#
# *uncomment* only *one* of the three *options* that you'll *use* as the first case!

[UMS] A list of quirks entries to supplement or
override the built-in unusual_devs list. List
entries are separated by commas. Each entry has
the form VID:PID:Flags where VID and PID are Vendor
and Product ID values (4-digit hex numbers) and
Flags is a set of characters, each corresponding
to a common usb-storage quirk flag as follows:
...
i = IGNORE_DEVICE (don't bind to this
device);

Thanks for all the info Poma, there is some very useful information in
those links. Even though the links say the camera is switchable between
the 2 modes I'm not sure whether it is manually switchable. The manual
and camera itself don't have any details on how to do it. It seems as
though it may be automatically switchable depending on the access
mechanism. Under linux it seems to be accessed via PTP but under Windows
(I'll need to double check this) it seems to be accessed in USB Mass
Storage mode as it seems to be mounted as a USB device. I was able to
remove files from the SD card on the camera using dolphin and digiKam
was able to access the files directly by auto navigating down to the
appropriate directory, but GIMP was unable to touch the camera at all.
regards,
Steve
