To quickly adjust highlights and tone of an image we can use Levels tool.
Open an image in Gimp and then to access level tools we will click Tools -> Color Tools -> Level.
Then if we want to work with level curves we will click on Edit these Settings as Curves button.
When processing an image the idea is to obtain an S curve that looks good, without blowing out image with too much white and without black/too dark areas.
Note: The same tool can be accessed from Colors -> Levels submenu.
Gimp level tool is very useful for image processing.
You already know about Gimp, the best free, open source photo editing app.
If you want to know how to scale an image in Gimp, here’s a quick how to.
1. Load your image in Gimp. If you are in Windows you will open the file using Gimp menu. If you are in Linux you might just run from command line: gimp photo.jpg. Yeah gimp knows command line parameters.
2. Scale the image by clicking: Image -> Scale Image. Choose a new width or height and press Scale.
3. This step is optional. If you’ve scaled down the image and you are not happy with image sharpness, go to Filters -> Enhance -> Unsharp Mask. This will make your image sharper. Adjust parameters according to your need, if the image is too sharp, lower down Amount parameter.
4. Save the image by clicking File -> Save as menu option.
Tip: If you scale down an image you might want to apply a little sharp effect to that scaled down image. If you scale up (enlarge) the image you might want to apply a little blur effect. That’s the recommended approach to scaling images.
Gimp is a very useful photo/image editing tool. The best thing is that it’s free. Second best thing is that it’s available on many platforms from Windows, OSX to Linux and FreeBSD (and other platforms).
Let’s say we have a selection from an image and we want to save that selection to a new image.
This task is very simple, so we will:
1. Select the part of the image we want to save using Gimp select tool.
2. Copy the selection by clicking Edit -> Copy (submenu).
3. Past the selection to a new file by clicking Edit -> Paste as -> New Image. Then we choose the image name and press ok.
If you want to know more about Gimp here is a Quick introduction to Gimp.
Today’s article will be a quick introduction to the GIMP, a free and open source
image editing program, which can be successfully be used for creating and editing textures
or concept art.
You can get the program at the following link (currently at the 2.6.11 stable version):
After you’ve installed and run it, three floating main windows will appear:
You can maximize the middle one (which will contain the digital canvas) and put the
other two on the sides, for a better ergonomy.
Here we are, for a second part of the Blender’s quick introduction. Today we’ll
throw an eye on how to create objects and modify them.
Ok, so, as you can see, when you open Blender you’ll see a cube. This is an editable
object that we can shape it to take whatever form we like. But, this is not the only
primitive/object we can build on it. If we press SHIFT+A, then choose Mesh, we can
choose from a list different kind of base primitives.
