1. Photoshop – Smart Objects Computer Information Technology Section 64

2. Objectives The student will: 1.Know how to open an image as a smart object 2.Understand what smart objects allow you to do 3.Know how to convert a layer to a smart object 4.Know how to place and edit smart objects 5.Know how to replace the contents of a smart object

3. Smart Objects Smart Objects allow you to transform pixel- based layers in new ways Smart Objects can be scaled, transformed and warped without destroying the original image. Smart Objects create a link to their source file. You can change the source file and the Smart Object will automatically update.

4. Opening an Image as a Smart Object Remember back when I introduced “Free Transform” I noted that if you shrink a image and then later try to grow it again you have lost image quality When you shrink an image the number of pixels is also reduced. This is called downsampling When you enlarge the picture Photoshop fills in the pixel information This is called destructive editing because the original layer has lost it’s detail

5. Opening an Image as a Smart Object Open the butterfly image as a smart object File>Open as Smart Object Note the layer has a different symbol: Move the image to the other file… Smart Object Icon

6. Resizing a Smart Image Shrink the image down to 25% and confirm the change. Note that when the image is enlarged the picture quality is the same as it was Also note that the % grows back to 100%

7. Converting a Layer to a Smart Image To convert a layer to a smart object

8. “Placing” a Smart Object An alternative to opening a file as a smart object and then moving into a image is to “Place” the object by File>Place The image is automatically created as a smart object

9. Editing the Content of a Smart Object There are few options for editing the content of a smart object In most cases the object needs to “rasterized” to be edited. The object will no longer be a smart object Limited options under Image>Adjustments Use of tools like the “Blur” tools require the image to rasterized.

10. Editing a Smart Object in Its Own File To change a smart object you must edit the source file. Double click on the smart object layer to open the original file Make changes to the original file When you save the file, the smart object will be updated.

11. Replacing a Smart Object To replace a Smart Object: Have a file to replace the object with Layer>Smart Objects>Replace Contents…

12. Summary Smart Objects retain all their original data Only non-destructive changes can be performed on Smart Objects Otherwise they have to be rasterized Edit Smart Objects by changing the original file.

13. Rest of Today Practice adding Smart Objects into a picture In the homework section download the africa.zip file and extract the files. Create an African scene using just smart objects. You will have to remove the backgrounds from the animals. Try and get the animals alone in a file. Show me your scene when done
