The technique of using a 50% grey layer in Overlay blend mode to dodge and burn on a layer below is well-known and very useful. However, with an image consisting of several layers, painting with white or black on this grey layer will affect all the layers in the stack below. In Photoshop there is a means to limit the effect to just the one layer below the grey layer, not all the layers. Does anyone know whether this is possible in GIMP?

Hello everyone I am new here.


I am having some issues with filling a Gfig shape I made. I'm not sure what happened I had filled the triangle before with a vertical gradient Red and white. Something happened that made it turn black and now it wont fill. The stroke is working just not the fill option any ideas?


                                                                                                                                                                                                                            Thank you.

                                                                                                                                                                                                                                                 

Is there a way to get that kind of circle arrangement with Gimp?
   
For example, knowing the radius, or the diameter and the number of desired circles, how to proceed to create this formation without the circles overlapping (only touching each other tangentially) forming a circle of circles.

I got something very close to this using (Ottia Tuota) Markku Koppinen's replicate path along circle plugin, but the adjustment between the source path and base path was on a trial and error basis.

In the image above, Inkscape was used.

I tried with the ofn-path-to-shape plugin, but I wasn't able to get anything close.

Any suggestion?

Thx!

PS.: Sorry about the title, but that's what I could come up with.

I've been using GIMP for a while now but still lack deep knowledge of some image editing concepts.  This particularly involves the difference between "Perceptual gamma (sRGB) & Linear light" found when selecting the menu item called "Image>Precision".  I've been inclined to think that this choice has to do with internal computational alternatives and that what I was really after was the resulting effect that could be seen on the display screen of the image being edited/viewed.  However, I had a recent experience where the appearance of the image being viewed when using GIMP for editing was dramatically different from the appearance of the exported image when displayed by some other viewing software.

Consider 3 examples pertaining to a photograph edited by GIMP.

First is a screenshot of a photo edited by GIMP ready for export to a standard image file as follows:

   

Second is a screenshot of an image (in .png format) created (i.e., exported) by GIMP of the exact same image (i.e., first shown) as follows:

   

Third is another screenshot of the same image (in .png format) also created (i.e., exported) by GIMP of the exact same image (i.e., first shown) as follows:

   

The big surprise is the difference between the second and third images shown above (that came from the exact same image as viewed within GIMP).  The difference is that "Linear light" was specified under Image>Precision for the first export whereas "Perceptual gamma (sRGB)" was specified for the second export.  When that change was made in GIMP there was no perceivable difference in the appearance being displayed within GIMP.  Nothing like the first exported image file ever appeared within GIMP.

I am working on an old baptismal certificate. It has a white background. There is what looks like
dirt on some of the background, which I would like to remove. It is also yellowed to varying degrees
which I would like to fix. I have used the brush/pencil tool and painted some of those areas
with a lighter color from the background but its too slow. Any ideas would be greatly appreciated.

Thanks.

I'm trying to add a custom pattern however I cant locate GIMP on my drive  through the gimp application( File-->Export-->OS©-->users>
(name)-->application Data(appdata roaming  is where gimp is stored when I search for gimp) once I click on this option the preview box on the right is empty.

I cant save the custom pattern without finding Gimp ( I can search my computer and locate the file, however when I search through the gimp app while exporting to save in gimp I can not find it).

Can anyone help?

Im using windows 11
Latest version of Gimp 2.0

Can I make icc files in gimp that the 'Apply abstract profile' plugin understand (found in 'Colours/Apply abstract profile' after placed in the gimp plugin folder) 
   

This FG/BG

It looks nice with my color, don't you think?

More seriously ➤ We always speak about this "Tool", some call it FG/BG swatch, I call it FG/BG icon, others call it FG/BG button and we always try to "explain" what's this icon, its position on the UI, when it's a very-beginner we do need to write the full "ForeGround/BackGround (FG/BG)" what so ever... and yet it's not in the icon's tool list on GF...



(Jeeez I love this direct screenshot to imgur from ksnip, and just Ctrl+V while writing > again thank you @Krikor ),
anyway, let's get back on track ➤ it would be nice if we can have this icon  
No need to try to explain to "click on the rectangle underneath the white square" (or vice-versa) or the double arrow or the tiny B&W square to reset it.... and let's face, it would be a nice add-on to the tool's icon list of GF    

PS: there is even the icon posterize, that nobody use it and not the FG/BG...  

Hi everyone,

I exported an image from a rendering software which had an option to 'apply alpha channel'. By mistake I enabled this option and later realized all my images had no sky background.

While viewing the images in photos (Windows) I noticed the background would show for a split second before Photos applying the alpha...

I opened the image in Gimp and when I unticked alpha channel, Voilà, the background was recovered.

Problem is... I can't export it for some reason... when I save as PNG the background is back to transparent, and when I save as JPG it is all white... but that is not what I am seeing in my GIMP window...

When I run Layer > Transparency > Remove Alpha Channel. I do get the white background preview.

It's always a challenge to optimise skin colour. I find this video a good learning curve.

I think you can find in gimp the same things as seen on this dashboard : Colours/Color Grading, Colours/Curves, Colours/Levels, layers, layer modes and I'm missing Vectorscape (I think). 
Nice to have such a dashboard. Just a dream...
