Editing Images with Canva, Part 1: Crop, Resize and Adjust

Students edit a digital image in Canva, a free browser design tool, learning what each edit does to how the image reads. They crop to change what the viewer's eye lands on, resize for where it will be seen, apply a filter, adjust brightness and contrast, stack elements as layers, and export. The lesson closes on the ethics of the crop: deciding what a viewer never sees is a real editorial choice.

    1 - Start ~4 mins

    Show the class the same photograph cropped two ways: once wide, once tight on one detail. Ask what each version says happened.

    Nothing was added and nothing was faked. The only decision was what to leave out, and it changed the story.

    Today you make those decisions yourself.

    2 - The Words Editors Use ~5 mins

    Five words you will meet in any image editor.

    • Pixels. The tiny dots a picture is made of. More pixels means more detail.
    • Resolution. How sharp an image looks. Higher is sharper but the file is bigger.
    • Cropping. Cutting away part of an image so what is left is what you want seen.
    • Layers. Elements stacked on top of each other, each movable on its own.
    • Exporting. Saving your finished design as a picture file. JPG for photos, PNG when you need sharp edges or a transparent background.

    3 - Open Canva and Crop an Image ~11 mins

    Canva runs in your browser. You need a free account, signed up with your school email. If you have not done that yet, tell your teacher now rather than working through it alone.

    Once you are in, you will crop an image so it says what you want it to say.

    4 - Filters, Brightness and Contrast ~8 mins

    A filter changes the mood of an image in one click. Brightness and contrast fix an image that is too dark or too flat.

    Both change how a viewer feels about what they are seeing, without changing what is in the picture.

    5 - Layers, Then Export ~8 mins

    Everything you add to a Canva design sits on its own layer, stacked in the order you added it. That is why a text box can sit on top of a photo and still be moved on its own.

    Then export, because a design left in Canva is not a file you can use anywhere else.
