Filters and colours with Gimp

 
This is an article prepared to help you learning how to do a mosaic of different versions of the same photo or several photos like the one you have here

Project instructions: here

The versions of the photos are going to be done using Gimp filters or just the edition of colour that the program offers. 

Find some photos here

Watch the videos to learn about it.

First part: Preparing the canvas and calculating the resolution of each of the pictures. Of course, the resolution of the single pictures is the division of the total by the number of pictures by line. Since in the example there are three pictures per line, then you have to divide by 3.


second part: Examples of editing the colection of photos to include in the mosiac 





third part of five: Applying filters and colour edition




Part 4 of 5: Cropping at the right aspect ratio, scaling to the right resolution, editing the colours and exporting the result




And finally to organize the nine pics on the final image. You have to open all of then as layers and distribute them carefuly.

Gimp 2. Selection and Layers

 Selection tools are designed to select regions from the active layer so you can work on them without affecting the unselected areas. Each tool has its own individual properties, but the selection tools also share a number of options and features in common. 

It is very important that you get familiar with the selection option and the selection menu.


Here you can watch these videos to do a photomontage using the combination of selection tool and layers.

๐Ÿ‘€Keep in mind that when you have different layers and selected areas the effect or the tool applies only to the actived layer and the selected area.๐Ÿ‘€

CHOOSE TWO OF THE FOLLOWING SITUATIONS TO DO THE PROJECT

  1. I have recently received emails and instant messages that look legitimate at first glance. These messages come with URLs that prompt you to input your personal information. In turn, I think It will steal my credentials and use them to access my accounts and personal data.
  2. I think my telephone has a type of malicious software that makes me believe that my cell has a virus. Sometimes, it will fool me into believing that my security measures are old. In turn, they offer new updates for my security settings. So I do not know what to do… 
  3. I have opened an email sent by a friend and clicked on a link that looked legitimate and harmless. Once i opened the attachment, it automatically downloads software to my computer. I do not know what has happened and how to fix it
  4. I always use the same password for all my accounts and applications. I do not like to use complicated passwords because it is difficult to remember and too long. What do you think?.... 
  5. My mobile phone is asking me to install my operating system update but I do not feel like to do so… Do you think it is really important to update it, why?
  6. My brother always uses public conections, like public libraries or cultural centers, to do his online works. He has an important job and manage sensible information about clients and business. I think this is not a good idea to use public wi-fi connections to do so… What do you think and why…
  7. I like online games and spend all my spare time playing on the computer and phone. I even prefer playing over going out with family or friends. My parents are all time telling me to organize better my time but I think it is my hobby and does no harm on me…. What do you think and why….
