  Rectangle Select Tool is only Square - Fixed
Posted by: micksulley - 02-27-2017, 09:58 PM - Forum: General questions - Replies (4)

GIMP 2.8.16 on Linux Mint 18.3

When I use the Rectangle Select tool it only allows square and uses the initial click as the centre of the square.  I have searched for help, tutorials show it working as I expected, starting at a corner and drag to the other corner.


I am not aware that I have changed anything, how can I fix it?

Thanks
Mick

  Editing or deleting one of several rectangle selections
Posted by: jbheadrick - 02-27-2017, 06:34 AM - Forum: General questions - Replies (7)

Hi,

Just started using GIMP, just found this forum, have a question I haven't been able to answer through my own research.

Let's say I use the Rectangle Select tool (in "Add to the current selection" mode) to select 10 different regions of my image.  Then let's say I want to change the size or delete rectangle selection #7.  How do I do this?

I know that I can use Select > None or do a Shift+Ctl+A to delete ALL of the rectangle selections, how do I edit or delete just ONE rectangle selection?

So, two questions:
   

  1. How can I delete one of several selections without having to start over?
        
  2. How can I edit a particular selection, such as changing its size?
   
Thanks for anyone's help.

JB

  What are animated brushes?

Can someone please explain what is meant by 'animated' brushes, as opposed to regular brushes?

  Looking for a particular type of brush
Posted by: OurJud - 02-26-2017, 04:39 PM - Forum: Extending the GIMP - Replies (3)

I began using Krita some weeks ago, after seeing it mentioned on here, and for some time suspected I preferred it to GIMP, but then when I was unable to get a particular effect/look to my work I switched back to GIMP and now prefer it to Krita.

However, Krita does have a few brushes that GIMP doesn't and I'm trying to find out if I can get something similar.

Unfortunately I don't know what you would call them, or whether they're 'animated', but their icon is a pencil tip and they're used for creating what I think are fractals. As you draw with them, very fine fractals will branch off creating nice wispy patterns. The others just seem to be variations on this.

I browsed the GIMP brushes on deviant art and found a few Fractal Brushes packs, and the previews showed what seemed to be the exact same effect, but when I installed them and went to use them, they're simply pre-rendered stamps of a fractal pattern, rather than a free-hand brush.

This is the kind of thing, but I need the brush to be free-hand rather than pre-defined stamps as these are.

Fractal Brushes

If anyone can offer any advice or links to the sort of thing I'm looking for it would be great.

  Add frozen object from short exposure frame to long exposure frame
Posted by: mikej411 - 02-24-2017, 06:50 PM - Forum: General questions - Replies (6)

I am going on a trip to the Yucatan in May and want to take good pictures inside some of the Cenotes (sinkoles that expose groundwater underneath). Some of these cenotes are underground with not much light (Beams of light from the sun come through from the holes at the top of the cave, and some stationary artificial lighting is provided from the people who work at these caves as well).

So my plan is to use my Rokinon 12mm f2.0 with my Sony A6000 on a tripod and set it to max aperture and long exposure, with maybe ISO of about 400 to 800. Do those settings sound about right to get some good low-lit cave pictures? Would there be any reason to lower the aperture? Keep in mind, I do not plan on going any further and setting up external light sources, etc. The cave should be lit enough to be able to grab a decent picture with long exposure.

Anyway, the more important question or concern I have comes into play when I want to get some action shots. Long exposures and people moving don't mesh, so I have to take a short exposure frame with flash from the same angle with the person, and then insert that person into the long exposure photo. For example, freeze the person when jumping into the water (in the air mid-jump). I think the only way to do that is with a computer program using layers or masks, correct? I don’t want to purchase anything, and I think this can be accomplished with GIMP on my Macbook pro.

Last night, I tried masking myself out of a picture (or whatever the term is), but it was very hard to do in terms of being precise. I tried to fiddle around with the lasso and the different detections (color/shape/contrast), to no avail. Maybe part of that was because I was on a small laptop without using a mouse. But I think most of it was because I am an extreme beginner and this is my first time playing around with photo editing tools.

Can someone please point me to some detailed Gimp tutorial videos either showing how to accomplish exactly what I want from start to finish (Add the frozen person from the short exposure frame to the long exposure frame), or if you don’t know of a video that explains all of that, then maybe some tutorials on something similar, like how to precisely mask out people.

UPDATE: I have included a picture of what I am trying to accomplish. The cave in question is pretty dark, so I am almost positive he used the method of layer masking to insert his self into a long exposure shot of that cave, from a short exposure flash induced shot with the same angle

  Help needed on border radius
Posted by: Fleetwin - 02-23-2017, 03:21 AM - Forum: General questions - Replies (4)

   
I'm trying to make a new decal from my vintage outboard. I'm using Gimp 2.8.
It's almost good enough (for me) but I'm having trouble getting the bottom border
radius' looking natural like the top corners, but otherwise, I have it shaped like
the original. Help or suggestions appreciated, Thanks!

P.S.- My off white "background" make it hard to even distinguish the
border on this forum. ..... not sure what I can do so you can see
the problem better.
