9. Click down and drag the mouse inward such that the grid goes to the right-most and bottom-most parts of the turtle. 10. Do the same thing from the upper left corner and drag it so that the grid is including the entire turtle but not more.

4 11. The gridlines should now look similar to this: 12. At the top, just below the Options Bar, there are 2 buttons: Apply and Cancel. Push the Apply button to crop the image given the gridlines you set. 13. Affinity may zoom in closer upon completing this crop so if it looks a little pixelated, just zoom out to 100% in the Navigator panel. 14. Now we want to remove the water and ocean floor around the turtle but cropping can't help with this anymore since the turtle itself would get cropped too. Instead we will remove those parts by erasing them and leave the turtle as is. 15. Before we erase the water, let’s take a sample of the colour of the water to use it later. Click on the Color Picker Tool near the top of the Tools Palette. 16. Move the cursor over the water (it will look like crosshairs) and click on the water in the image to get that shade of blue. This should change the Fill Colour Circle to be the colour of the water.

Notice at the top, below the option bar, the Tolerance is set to 20%. Click on the top left corner of the turtle image in the water area (not on the sea floor nor on the turtle). Notice that it erases parts of the turtles body. This is because it is looking for pixels in colour that are fairly close but not the exact same shade of blue as the water. This is not precise enough, it removes too many pixels. 19. Hit Ctrl+Z to undo this. 20. Now set the Tolerance to 0% and click on the water. Notice that now it only erases pixels that are that EXACT shade of blue. This is too precise. 21. Hit Ctrl+Z to undo this. 22. Now set the Tolerance to 10% and click on the water. This should just remove the water. 10% works well in this case. Your image should look like this: 23. Try to click on the seabed now to remove that with the tolerance still at 10%. This tool does not work well n. Try changing the tolerance to 30% and click on the seabed again. Now we remove parts of the turtle. (Similar to the image below). This tool only works well if most of the pixels you are trying to remove are the same colour BUT they are quite different in colour from the pixels you are trying

6 to keep. 24. Hit CTRL Z to undo this. 25. We will use a different tool to remove the seabed. Click on the Erase Brush Tool this time. 26. There are settings along the top under the Options Bar. Click the little white arrow beside Width (the leftmost setting) so that the slider panel pops up. Drag it over to 50 px. This is the size of the eraser we will be using.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
