If you use Nikon's own ViewNX-i [available for free from Nikon] it can Link edited to hopefully now always find the latest version a) batch convert to jpg [Export, set parameters, Convert] & more importantly … b) make a much better job of knowing what the camera's settings were supposed to be than any 3rd party app.

The crop tool has an option to lock the aspect ratio (or the absolute size , or the height...). You click Fixed, select Aspect ratio and enter an aspect ration in the form W:H: Using the icons at the bottom of the Tools options, you can even save this as a tool preset, and reload it for later use...

Stop using Photoshop for the 3D part. There are better options out there, and free. I will dive into it later. Study the wonderful and profound paper I made about projections. https://www.otake.com.mx/Apuntes/Imagen/EnviromentMaps/ The basic idea is that you need to understand that putting a 2D image into a 3D sphere is a bit complicated and you need to ...

That "border" indicates the layer boundary: nothing can happen outside of it. But you can increase the layer size to cover the whole canvas with Layer>Layer to image size.

Yes there is setting you could use, but not with the Brush tool. Select the Clone tool instead, then in the Tool Options choose a brush shape, set the Source option to "Pattern", and Alignment to "Aligned", and choose a pattern to paint with from the Patterns dialog. There's also another technique. You could fill a layer with a pattern, or even just open ...

It's not a bug, and reinstalling GIMP won't fix it. From your screenshot I can see the problem. The layer you have selected is hidden, and another potential problem is that the top layer is visible and is therefore covering the selected layer below. To edit a layer in GIMP it must be visible. You must enable the "eye" icon in the layers panel for the layer ...

You can try GIMP's Color > Color to alpha. You must combine with layer masks one version which is otherwise well separated from the background but the wings are still green another version where the wings are transparent as wanted but something else green has also vanished Hopefully you have a high resolution photo. The shown version in the question is ...

Unlike a physical pixel in a screen, a digital image pixel has no specific size. It can be as large or small as you want by defining the image's ppi. A 100 x 100 pixel image at 300 ppi, is no bigger than a 100 x 100 pixel image at 72 ppi. 100 pixels = 100 pixels regardless of how big you stretch them. A digital pixel is the smallest editable element of an ...

The settings are automatically saved as a preset when you apply them. You can retrieve the settings by clicking on the drop-down selector at the top of any adjustment dialog next to the label "Presets". The text boxes will then be populated by the settings of your previous adjustment. In this screenshot, the levels adjustment on 2019-12-02 is the only one I ...

Possibly a bug. When I repeat your steps, in the image print size (Image>Print size) the print definition has been reset to 72PPI (and since the size in pixels hasn't changed, this gives the strange print size). Forcing the print definition back to 300PPI seems to fix it for good (doesn't change with later exports or edits). PS: made a bug report

GIMP does not support UFRAW. Open a RAW file directly in GIMP and you'll see this error: GIMP Message Opening '/path/to/file/_DSC0001.NEF' failed: 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'm a bit late but in the angle part of the paintbrush options, set it to -90 or -180 depending on whether you want it flipped vertically or horizontally

There was a plugin in the GIMP plugin registry that did this. It's archived here now. Some time ago I translated this to Python and it ran a lot faster. Here's the result of its application to the image in the original question: Here's the result of its application to the image in Alan's answer: Anyway here's the code of the plugin: from __future__ ...

What I usually do is to open an image, select all, copy, create a new file (or create from clipboard), then close the original and work the copy.

Python "scripts" are technically plug-ins, not scripts, so they got in the "plug-ins" subdirectory. On Linux, they should have the executable flag set They have to "register" with Gimp (they make one or more calls to the register(...) functions Typical debug technique: Add a bunch of print statements, typically: a wide print '*********************' at ...
