I am trying to use gimp to edit NEF (nikon RAW) files, but it gives me this message:   

There is no RAW loader installed to open 'Raw Nikon' files.

GIMP currently supports these RAW loaders:
- darktable (http://www.darktable.org/), at least 1.7
- RawTherapee (http://rawtherapee.com/), at least 5.2

I attempted to add RawTherapee, but must be doing something incorrectly because i am still unable to open the files in Gimp.

Could anyone tell me which of the loaders they recommend, and how to install it so it will properly work with gimp? 

Thank you!!   

If I wanted to take a picture like this (or any other picture for that matter) and make the colors more similar and the brightness of the colors more similar, how would I do that? I've exhausted my methods and have came up short.

I just started using gimp for painting and drawing. I was drawing some subjects on a red background with a dark hue. As I was using the measuring tool to get the proportions right, suddenly all the dockable dialogues disappeared and the image became full screen. I don't know, maybe I did the wrong click in my stylus. Not knowing how to get the image to leave full screen, I rest gimp to the default settings. I restarted the program and I got the image to go back in a smaller window and the dockable boxes to show. but the drawing is misbehaving. All the colors I use with the brush show muted on the red background. Other files do not this. I think there must be a layer or something that I accidentally activated. I am attaching the file, I hope it works.

Hi,

Is there any solution to create a 3D cube with full-size pictures on each (visible) side, with rounded edges and corners?

Thanks, Toni

Hello, I work in forensic science and am teaching a lab at a university using the subtraction method for footwear and fingerprints.

Effectively I have 2 photographs taken using a tripod and the same lighting and camera settings (I have JPEG and NEF files for both photographs)
 - 1 is of a dusty partial footwear mark on a wooden floor
 - 1 is of the wooden floor but with the footwear mark completely cleaned away after the first photograph

I want to subtract the background (cleaned substrate) from the photograph showing the footwear mark, leaving only the footwear mark which will hopefully reveal more detail that was visibly lost in the wood grain background. The background can often interfere with visualising the print, especially with fingerprints and so the removal of the background can reveal fine details in ridges, valleys and pores etc.

I have experience using the subtraction method in Photoshop but as this is a university course I am unable to get multiple licences due to funding etc and so I have started playing around with GIMP instead.

I have tried a few methods I found online loading the images as layers and playing around with the subtraction and difference modes with some success but was wondering if there were any other settings/changes I could use to improve this? 

Also, is there an auto-align function in GIMP? e.g. solid lines between floorboards are aligned, not just the photographs themselves. As much as I try not to knock the tripod between photographs there sometimes can be very slight movement.

Thanks for your help/advice, David

Hi everyone,

It seems that Gimp Chat is not working correctly for me.
I was wondering if anybody else has experienced this.

Hi all,

New member here. For quite some time my GIMP 2.10's been working like a dream.

Now, however, the rectangle select tool is stuck on expand-from-center - a major time-waster rather than freely manipulating the four points of the rectangle. 

How on earth does one toggle it off? Many thanks!

Posted this on the dead forum (why is it still there if it's dead?):

I mentioned this a year ago, but the problem is still there so I thought I'd shake the bushes a bit:  My Canon MG5220 printer doesn't work with GIMP.  It works flawlessly with every other application I have on my Debian stable distro.  As I've read elsewhere on the web, you do your modifications to an image in GIMP, then you save it and use another app to print it.  Really? 

The printer does nothing at all except that the little activity screen says that information is being received but nothing physical happens. It's exactly the same with Gutenprint or the 'normal' print.  Can't this be fixed guys? Every other app prints to the Canon without any trouble.  As it is, for simple work I'm now using fotoxx which prints fine, but I'd rather be using GIMP.

Hi,
Really new to everything, so please bear with me. When I use selection tools like ellipse or rectangle, the whole canvas starts sliding diagonally to the right bottom corner and lines become gradually thicker until everything kinda "melts". Started new files several times - no joy.  The attached screen shot shows rectangle selected around text after 2 seconds.
Any help will be greatly appreciated.
