I also practiced creating a sunset background, sketching trees, leaves, and birds, adjusting brush sizes for detail, and enhancing the overall composition to make it look natural and dynamic.

PIXLR

PIXLR is used for editing photos, creating graphics, and designing images without installing heavy software like Photoshop. It supports both raster editing (pixel-based) and layer management, similar to Photoshop. It’s beginner-friendly and accessible on most devices because it works online

Key Features
  • Crop, resize, and rotate images
  • Adjust brightness, contrast, and colors
  • Add text, stickers, and overlays
  • Layer-based editing for advanced designs
  • Supports common formats like JPG, PNG, GIF

Using Artificial Intelligence (AI)

With Pixlr, you can generate images by using text prompts. I created a new file and opened the AI Image Generator, as highlighted below

With Pixlr, you can generate images by using text prompts.

I then typed prompt (People talking in a café)

2D vector Design
CorelDRAW

CorelDRAW is a vector graphic design software used to create and edit illustrations, logos, posters, banners, and other graphic designs

Key Features
  • Vector drawing tools (shapes, curves, paths)
  • Text and typography tools
  • Color management
  • Page layout and alignment tools
  • Export to formats like PDF, SVG, PNG, JPG
CorelDRAW Instation

To install CorelDraw, I downloaded it from CorelDRAW website. I used free trial. After install, I started right away. The picture below is the blank page of CorelDRAW.First step, I set document size of 300x600mm

I exported the file by following the highlighted steps.

At the export stage, it is important to select the format carefully because CorelDRAW supports various options.

I chose PDF as the export format to ensure the design retains high quality and can be easily shared or printed

Inkscape

Inkscape is free and open-source vector graphics software used in the editing and production of scalable vector graphics (SVG) or vector files. It is used in creating illustrations, logos, technical drawings, etc. As the same of coreldraw, it also support the import and export of several file formats such as PNG, PDF, DXF, EPS. It is vector-based. This means it uses SVG as the default file format such that the design is maintained to be scalable without loss of quality.

After opening Inkscape, a blank page appeared where I started my design

TINKERCAD

Tinkercad is a free online tool used for creating 3D designs, especially for beginners. It was created by Autodesk and is easy to learn. o use Tinkercad, first create an account on the Tinkercad website. If you already have an Autodesk account, you can simply choose Log In instead, as highlighted in the image below.

Compressing my images and video

This week I took a lot of photos and screen recordings, and some were several megabytes, which is too heavy for a website. Before I uploaded them I made them smaller so my pages load fast.

For the images I used Squoosh, a free tool that runs in the browser, so there is nothing to install. I opened squoosh.app, dragged each photo in, set the width to about 1600 pixels, chose MozJPEG with the quality slider near 80, and downloaded the smaller file. Most of my images dropped from a few megabytes to under 300 kilobytes with no real loss in how they look.

For the videos I used HandBrake, a free program I installed on my Windows computer. I loaded the clip, chose the Fast 1080p30 preset, set the video to H.264 with an RF quality around 22, and encoded it. This made the videos much smaller while they still play clearly.
