Use multiple versions of the same image to explore the image adjustment tools and filters in Photoshop. Remember to try many different filters and colors. No two images should look the same!
NOTE: The Photopea and Photoshop instructions are similar, but they have several significant differences.
Photoshop or Photopea, Photo Booth
The upper left corner of the Photo Booth window shows three “traffic dots.” The red dot closes the window. The yellow dot minimizes the window to the dock. The green dot makes the app full screen. Select the green dot, like this:
Click and hold on the thumbnail (the small picture) of your photo. Drag the picture onto desktop.
From the tools menu on your left, select the crop tool.
The crop tool cuts off edges of images. When you switch to the crop tool, the context menu (near the top of the screen, right above the image name tab) will change to show controls for cropping images. If you haven’t used it before, it will show a control that says “Ratio.”
Select the arrow to the right of “Ratio” to see a list of crop modes. Select “W x H x Resolution.”
Now there will be three empty boxes next to W x H x Resolution. They are for the width, the height, and the number of pixels (square dots) it takes to make a line one inch long.
Set the size to 4.5 inches wide, 6 inches high, and 150 pixels per inch.
You’ll see the crop box change shape to match the new width and height.
The crop box has handles on the corners and edges that let you resize it. You can also click inside the box and drag to move the whole crop box around.
Select OK to close the duplicate image window.
The center image copy file will appear. It may look like it’s a different size, but that only means that Photoshop has changed the zoom (how close you’re looking at the picture).
Both files (center image and center image copy) are now open. You can switch between them by selecting the tabs at the top of the window.
Change the width to 1.5. The height will automatically change to 2.
Select the OK button to resize the picture. it will look pretty small.Now we’re going to open a third file. This will be the big blank page where we’ll place all of the little pictures.
Switch to the “Center Image” tab (at the top of the image window).
On the tool menu, select the Move tool (it looks like four arrows):
On the right side of the screen there is a window called “layers.” It only show one layer, called “Background.” The is a thumbnail (small picture) of the background layer.
Click and hold on the background layer.
Switch to the “center image copy” tab.
On the text menu, select “Filter,” then “Filter Gallery.”
The Filter Gallery window will open. There are multiple sets of filters on the right side of the screen. As you select each one, different controls will appear.
When you find a filter effect you like, select the OK button (top right corner of the window).
Switch back to the center image copy.
Continue adding small images around the outside to fill up all the space. Experiment! Use lots of different filters!
