My analysis of a video tutorial on the knowledge and skills needed to remove the background of an image in Photoshop. The video is about 6 minutes in length and available to view below (https://www.youtube.com/watch?v=t6hvuUf2Smw).
To complete this task students need to identify three tools located in the Photoshop palette and their function.
- Quick Selection Tool: used to select portions of an image and looks to be done through a selection of similar colors in a given area.
- Polygon Lasso Tool: Another way to select an area of an image by creating a polygon shape.
- Erase Tool: used to remove/clean up the edges of the image after it was cut out.
Skills:
- User needs to know how to use the quick selection tool. From the video this was done through demonstration by selecting the tool in the palette to turn it on and then using the mouse to select specific portions to cut out. The user also needs to know to use the subtract function of this tool, which was used to remove additional excess areas.
- Using the polygon lasso tool. This is done by selecting the tool and then using the mouse pointer to direct where the tool should draw the next edge of the polygon. Selecting a point where two edges meet will close the shape. In the video the subtract function was used to cut out specific portions inside the selected image.
- User needs to know how to take the selected image and move to a transparent background. This meant to create a new file and modifying the settings so that the background was transparent. User then moves the selected image onto the transparent background by clicking and dragging it.
- User needs to know how to save the image. (This topic was not covered in the video.)
- User needs to know how to place the saved image onto a new background. (Not covered in the video.)
