Hello, I am new here and I just installed Gimp 2.10 on my MacBook Pro.. I am using MacOS Big Sur. I have problem opening up my pictures and i get som varning as attached. What is the problem here?
My GIMP all of a sudden has been exporting and opening files really slowly. Been like this for the past couple of days. Not sure why. Even the smallest file takes a couple of seconds. Everything else runs perfectly fine. I have no other issues with my CPU. Just the process of exporting and opening files in GIMP has changed drastically over the past couple of days. I uninstalled and reinstalled GIMP and still am having this issue.
I have seen others with this solution. Some seem to be able to fix it, but I don't see their solution or understand their solution. If someone knows the solution to this and could dumb it down for me. I would really appreciate it.
While using the airbrush, as I shift/left click to advance a line, Gimp freezes and then I have to manually crash the program, losing all my session's work. I tried waiting for it to come back, but I always have to start everything again. I use the paintbrush to avoid that. Gimp also freezes if I shake the mouse too rapidly while erasing. I can understand it's a constantly improving program, and I'm happy to be a user, so I do tolerate it to certain point. It is damn frustrating. I always have trepidation using Gimp for that reason, and I am constantly manually saving. Sometimes though, you just get focused on the task and forget to save for a while, and that's when it happens. I think the program is great, it's really helped me out working with .DDS files and creating Composites from the RGB channels, it's brilliant, but the freezing, ugh.... What can I do here besides avoid those features of the program? I have a I 7 with 16gig of RAM. The largest files were 8192 x 8192 and possibly 50 layers. But it's happend on smaller files too. Any suggestions? Thanks.
Is there a way to take a flat 2D image of a building (front view, no perspective) and add a sidewalk coming off the porch entrance that looks 3D? See example.
I have used GIMP many times to create animated online ads - sort my frames out, add the frame timing to the end of the layer name (x000ms), etc.
Never had an issue - when I come to do it today it seems it always uses the default timing provided in the save options even though I have specified the required timing!?!
Have gone back to a previous one, saved that and it works fine - I can't see anything I am doing different.
I did use the playback preview within GIMP and that showed it working fine - just after exporting it it fails.
I have three questions together really, I apologise in advance - I want to move a box, delete an item and dock a box to another.
I suffer from poor vision and the layout of GIMP was set up for me by a friend. Recently, the Tool options disappeared and in its place "Core pointer" appeared where it used to be (I never had that before). In this situation I was unable (for example) to change the ratio of the rectangular select tool (or even to enable/disable fixed ratios), change brush styles/sizes, fonts or anything that would normally be done from the Toolbox Options. I found on the forums here a recommendation to enable, then disable, single window mode to overcome this, it appears not to have only happened to me. While this has worked, it has put the Toolbox on the right hand side of the options (see the attachment), presumably because its place has been taken by "Core Pointer." In "Configure Input Devices" I am unable to deactivate Core Pointer. How can I move the Toolbox to the top, delete Core Pointer and dock the Tool Options to the bottom of the Toolbox? I want something like this, but with floating windows:
I decided against resetting everything to default because, as I remember, everything came up in black and white, which I simply cannot see. Please don't suggest dragging and dropping, something which doesn't work on my system (it never has - the boxes will move but not dock), but if anyone can help me with any other suggestions it would be very much appreciated.
My hobby is astrophotography and what I cannot do with Siril in linear image or in PixInsight LE in non-linear image I do it with GIMP.
I would like to ask you a question regarding several closely related processes.
I work with raw format that I convert to TIF. In photographs with a high dynamic range, and assuming there has been no loss of information in lights and shadows, it is necessary to increase light in shadows and reduce light in highlights, and then increase local contrast. In GIMP with the G'MIC plug-in I find several processes that I can use. If I use masks I can use them on certain areas and if I break up the image with wavelets
I will be able to use them only on certain structures (stars or nebula).
In relation to the dynamic range of the image:
1. Colors > Exposure (exposure for me is a combination of aperture, ISO and exposure time, but this process has two sliders for shadow level and 'exposure'). There is a tutorial to bring up the shadows, but what about the highlights?
2. Colors > Shadows/highlights
3. Colors > Brightness/contrast
4. Colors > Auto > Equalize
My doubt with these is because I think that they are several perspectives of the same thing: the modification of the black point, the white point, and the midtones in the histogram; and I have no information on whether they cut out the information or not. Is there any other tool that will help improve the dynamic range of this
type of images?
Regarding the dynamic range, and trying to be clearer, I am looking for a tool that allows me to increase the space of the shadows and the highlights, at the expense of a compression of the midtones, so that I can extract detail from the extremes of hystogram (and this is not only to move three points in the hystogram I suppose)
And to increase the local contrast:
1. Filters > G'MIC > Details > Local contrast enhancement
2. Filters > G'MIC > Details > Tone mapping
Are they the same? From a technical point of view, could someone tell me what each of these processes does?
Have hundreds of old slides to scan in, and unfortunately, the majority of them seem to be Kodak Ektachrome, and have a red/brown tinge to them.
Is there a good tutorial around, or an "easy fix" to correct this? (He says, hopefully...)
