I have a grayscale layer for a Displacement Map. Its basically neutral gray, but there are other bits in various grayscales.
Because of processing, the basic gray changed and is no longer neutral gray.

How do i adjust it so that its exactly 50% gray again (808080) ?

When i use something like Levels or Curves, the tool doesnt tell me when im at my desired value.

There must be another way than just eyeing it.

   

Is there a way to enhance photo taken from physical LCD screen?

You can see the extreme pixelization on the forehead.

dear all,

i am a newbie in GIMP. so i need some help. 
as you can see that from the attached pic, that I had done not a bad job by chopping off the blue color on the top using the Fuzzy selection (Magic Wand) tool (i selected the smallest brush i could find) but it needs to be refined a bit more as the interface still contains a haze of blue. 
can someone suggest me how to improve this ? 
thanks a lot and best wishes for the new year !

I would like to use GIMP for making virtuals of trees' images changing the potting angle, branch placement, the pot etc
If I have one branch which at some point makes a curve at a right angle and I would like to change the right angle to an acute angle what should I do?
I understand I have to make a selection at first. A selection of the part which has to be transformed. Correct?
Then do I have to use some of the transform tools?
Does this thread answer my questions? https://www.gimp-forum.net/Thread-Gimp-s...ight=angle

Thank you in advance.



P.S. I apologize for any grammar/syntax errors... English is a foreign language to me...

Does anyone have or know where to get 3d Extrusion.  I've searched everywhere with no luck.  I never realized how handy the GIMP Scripts site was till it shut down.

Thanks in advance for any help you can give.

I really love the way your present your screenshots !
It looks very elegant with the arrow maker plug-in and the handwritten font.


Or is that your real handwriting ??


   

I'd like to clean up a short piece of handwriting (like a signature; see attachment). I found some kind of thresholding in Gimp, but ended up cleaning a lot with the eraser.

Could you please suggest an approach / tools that seems best to get a single color version of the writing only?

Ideally it should be the lines only, no stray dots, a fairly smooth edge of the written lines and in the end a single color stroke.

For the life of me, I can't figure out which filter was used when editing these colors. It's like an exposure that pops the color, and at it's highest point turns black into something silvery. Any ideas? 

I would like to create an oval gradient. Kind of like the radial gradient except it radiates out in an oval shape instead of a perfect circle.

If there is no such thing as an oval gradient, then perhaps there's a gradient that fills an oval shaped selection. Can this be done?

When I open a photograph stored in .tif format a dialogue box (see attached file) opens asking if I want to convert to RBG working space.  The message says the file has an embedded color profile identified as "sRBG v1.31 (Canon)".  It seems to be asking if I want to convert to something called "sRGB IEC61966-2.1".

It sort of looks like the choice is between 2 versions of sRGB where I have no idea what the difference might be but do think that the embedded profile might be one associated with my camera by its' manufacturer (i.e., Canon).  I also own a photo printer which is also manufactured by Canon.  Insofar as one of the uses of the the results of any editing done by GIMP is to print, I can't think of any reason to do this conversion.  What am I missing?

BTW I did experiment with both options (Convert & Keep) and output files exported to .tif format seem to retain the choosen option.  In that, there is no conversion done when the file is exported.  The differences on my display which is a moderately good (27" 1920x1080) one (but has not been calibrated) are imperceptible.
