hi there,
it depends what pograms you are using.
First of all I have had repeated problems with NEMO as the default file explorer. I have had much more success with NAUTILUS.
Open a terminal
sudo apt-get install libopenraw1 libopenrawgnome1 gnome-raw-thumbnailer nautilus
restart.
Open terminal
type nautilus and navigate to the folder where you images are located. YOu should see the thumbnails.
For raw image processing I can highly recommend darktable.
let me know how you get on.
also check that your graphics card driver is up to date! You can check this by going into menu, setting device driver. you will have to enter your password, after which it will automatically search for proprietary device drivers like for the graphics card.
is your OS up to date? I just noticed that you are talking about files from a 3300. It could very well be that this camera is not supported by the OS at the moment because the libraries that handle raw have no profile available for the 3300. I seem to remember a simlar problem last year in december on another forum with a D5300.
If you want, you are welcome to send me one of your raw files (dropbox download link for example) and Id be happy to check it out for you on my system.
Also please let me know what version mint you are using.
Darktable doesn't do it, as was mentioned.
on the contrary, according to a previous post the OP is having the problem with Raw Therapee, Darktable, Digikam and UFRAW. I am sure it must be a profile issue where there is no base curve preset for the D3300. I would love to get hold of one of his NEFS to see if I have any problems opening the file.
