adob photoshop notes class 8
6. Exercise with multiple layers
In this chapter you will get acquainted with one of PhotoshopÃ¢â‚¬â„¢s best and most practical facilities Ã¢â‚¬â€œ that is the ability to build a picture in multiple layers.
What are layers?
Imagine a stack of transparent plastic sheets. You can draw, paint, insert pictures of any kind, adjust brightness and contrast, insert text etc. on each sheet. All work on any one sheet is quite independent from the other sheets. But in the end all sheets are combined for the final picture.
The combined picture:
Figure 12. The layer function in Photoshop is incredibly smart designed. You can make countless manipulations, collages, transitions etc. The neat thing is that you add a new layer for each new element. It works quite easy, once you figure out the system.
In Figure 12 you see an example of a picture with two layers. Notice that the car in layer 2 is seen on a transparent background. The ckeckered area indicates that the picture area is transparent. Therefore Ã¢â‚¬Âyou look throughÃ¢â‚¬Â layer 2, and layer 1 becomes background in the combined picture.
You can add new sheets as needed, remove others, change their sequence, make some elements more or less transparent, drag the picture elements around on the screen Ã¢â‚¬â€œ the possibilities are nearly countless.
Create a new picture
You are now going to do an exercise that introduces the layers.
First we need a background color, and we need to select that in a different way than before. Where the Swatches palette lets you choose from a variety of pre defined colors, you can choose any shade of color with the dialog box Color Picker.
1. Click on the backmost of the two color fields:
2. Then the Color Picker dialog box opens. Choose a color by dragging in the slider on the small, vertical rainbow Ã¢â‚¬â€œ we need a violet, so the slider needs to get near the top:
3. Then click in the large square field to fine tune the color shade, in this case you need to get up in the uppermost part. Then click OK.
4. Open a new picture. The quickest is to use the keyboard shortcut Control+n, but you can also use the shortcut Control+Alt+n, which gives a new picture of the same size as the previous.
5. Name the picture geometry, and make sure that you have selected a background color in the contents section in the dialog box (like in figure 13). Then click OK.
6. Then save the picture as a file on your hard disk as geometry.psd (the procdure was described in the previous exercise).
7. If you prefer you can fit the work area to screen. You can do that with the shortcut Control+0.
8. Hide the rulers with Control+r.
