Completely new to gimp here, so I've been trying to do this for about an hour and it was a complete failure. I understand this is a complex software so the solution might be simple but not intuitive for begginers. I want to remove the sides of the image so the edges of the image are as close as possible to the phone .



I want to remove the red highlighted zones and then export the new image with alpha layer in the back. I know there should be like a million tutorials about this, but I couldn't find any adressing this issue directly. Any help?

 I attached the original image that i want to edit just in case.

So for some reason gimp became like this, I've searched everywhere and tried everything but I just seem to miss how to fix this. Anyone know what's happening?

This just started happening today.  

When I click on any layer in the image, it immediately switches the selection back to another layer.  It's always the 'same' layer.  
But when I click on a layer in the Layer Tab, it retains that layer as the one it switches to, if I click on a layer in the images.  Hope that's not confusing.  

I have rebooted and checked my controllers to make sure nothing is interfering with things.  I have rebooted.  And I have created a new image and added some text layers. And that image and layers has the same problem. 

I tried googling for a fix, but found nothing specific to this issue.  
Any help is greatly appreciated!!  

Hello

I am occasionnaly worker with GIMP and I am generally use it for photography.
I will need to generate a very large image full of pixel and I discover a tuto for PS:

Something like that with some actions I don't know in GIMP

1. Bring all images into Photoshop as a stack of layers
   
2. Resize the image to 200% width and 200% height using 'Nearest Neighbor'
   
3. Auto align all the layers
   
4. Average the layers by setting each layer's opacity to 1/layer number (the 1st layer will be 1/1 so 100% opacity, the 2nd layer will be 1/2 so 50% opacity, and the 4th layer will be 1/4 or 25% opacity, and so on).
   
5. Sharpen the image using a Radius setting of 2, and a suitable Amount setting (we used 200% for the 4 image stack and 300% for the 20 image stack – the more images you stack the more amenable the composite will be to aggressive sharpening)
   

The only way to get the full dynamic range out in a render or bake is to save it as an EXR float from Blender. Not even saving 16-Bit PNG float will keep all the information in the highlights in Blender. But many applications call for another format other than EXR. Such as PNGs and even Jpegs.

So is there a way to compress the full dynamic range information from the EXR into a 8-bit PNG using Gimp? So basically all the HDR info in the EXR file can be seen in a 8-bit PNG and the highlights are not blown and the shadows are not crushed. In video, Log does basically that. Squeeze the dynamic range which normally couldn’t be handled by Rec709 into rec709.

Anybody knows how to do that with EXR to 8-bit PNG in Gimp? Again, I’m aware of the limitations of 8-bit PNG, but this is what I need to output to. So my question is really how to compress the dynamic range to fit the 8-bit limit.

Thanks

Hello everyone, 

I opened the Bump Map dialog, then tried to choose an existent layer through the spinner (Presets , however, I didn't found in the Presets field despite I have layers that I already created. Confusing, I need to point this layer so I can work on.

Thank you for your help.

I'm trying to create a texture mask for a game map, and need to select the cliffs on my terrain. How can I select the areas where the pixel value is substantially different from adjacent pixels by a certain amount?

I have a problem with my brushes.  Every time I move my brush it rotates and cycles between large and small.  What did I press to cause this. 

Thanks for the help.
