  Strange results from Display Filters>Clip Warning
Posted by: ajax - 09-22-2018, 04:56 PM - Forum: General questions - Replies (6)

As pretty much of a novice when it comes to digital image editing it seems like the idea of finding the portions of an image where clipping is occurring might be pretty basic.  It looks like this is done via View>Display Filters with the Clip Warning filter active.  I think I understand what Highlights and Shadows are but have no idea when it comes to Bogus Color.  I'd suppose that anything clipped might be considered Bogus.

When reading the help pertaining to Display Filters I find the following:

This filter allows to visualize underexposed and overexposed areas of a photo with user-configurable colors. For now, it’s mostly geared towards images where colors are stored with floating point precision. You will mostly benefit from this, if you work on 16-/32-bit per channel float images such as EXR and TIFF.

This is not very helpful.  Given that I'm working in 16 bit integer precision it comes across as something I ought not be using but surely I should be expected to want to know what is clipped.  How is that reconciled?

Furthermore, the strange results really arise when Clip Warning is Active and then View>Color Management>Soft Proof is also activated.  This seems to have the affect of turning the Magenta color used for out of gamut identification, when Soft Proofing, into Black which of course is a color that is not associated with either Clip Warning or Soft Proofing.  Black is also a pretty bad choice for any such warning since shadows that are NOT clipped include colors that are dark (i.e., nearly if not black).

I'm having a hard time finding any images that show some clipping when the Clip Warning is active.  This is true even though other software such as Rawtherapee does show fairly extensive clipping clipping on some of the same images.  Maybe this is what the documentation meant when saying "For now, ..." but does that also mean DO NOT USE GIMP for my scenario.

My thinking would be that the difference between Soft Proof and Clip Warning is what color profile is applied.  Soft proof should apply the profile associated with a specific choice of printer/paper/ink whereas Clip Warning would apply the profile for my display device which, by the way, has been calibrated.

Any elaboration that helps with the above dilemma will be appreciated.

  adding Noise to a white layer in 2.10 vs. 2.8
Posted by: Espermaschine - 09-22-2018, 11:41 AM - Forum: Gimp 2.10 - Replies (2)

I can add b/w RGB Noise (with Independent RGB unticked) to a white layer in 2.8 but not in 2.10.

Why is that ?

Question Circular text Upside Down
Posted by: KamilBennouna - 09-21-2018, 08:52 PM - Forum: General questions - Replies (5)

Hi guys, new to this forum and to gimp overall.
I was trying to make this logo, and to put a circular text on the upper part of the circle. The problem was that the text kept going on the bottom, and if I rotated it and/or flipped it so it would be on the top, the text would be upside down.

Thanks for the help

Anyone know why?

  Placement of Add On Manager folders
Posted by: Pat625 - 09-21-2018, 08:13 AM - Forum: Extending the GIMP - Replies (2)

Is it possible to move all of the Add On Manager folders out of the user profile and Gimp itself?  I would like to have it outside of the GIMP program as I find it time consuming to reorganize every time we have a version update of Gimp.

If this is possible, how do I set it up so the folders can be found by the program. Do I make any changes in the main Edit/Preferences/folders menu or leave it alone?

Thank you in advance for letting me know what is possible and how to do it.

Windows 10, 64 bit    Gimp 2.10.6  Samj version

  How do I achieve this particular effect?
Posted by: Audrey Hossain - 09-21-2018, 04:52 AM - Forum: General questions - Replies (4)

My question is a bit hard for me to word, so I instead made a simple illustration to demonstrate what particular effect I'm trying to achieve:

Basically, I want to do what is shown in the image, but with this weapon:

Firstly, is this possible on GIMP, if so, what tools may I use?
Any help is welcome.

  Drawing tablet pressure sensitivity
Posted by: ningaman151 - 09-20-2018, 10:13 PM - Forum: General questions - Replies (2)

When I draw the start of the stroke is always transparent and then it becomes opaque. I attached an image to show what is happening. The top is the start of the stroke. I tried different brushes but the same effect persists. I am using the pressure opacity dynamic.
