Photoshop – Smart Objects

Computer Information Technology

Section 7-8


Objectives
Objectives

  • The student will:

    • Know how to open an image as a smart object

    • Understand what smart objects allow you to do

    • Know how to convert a layer to a smart object

    • Know how to place and edit smart objects

    • Know how to replace the contents of a smart object


Smart objects
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.


Opening an image as a smart object
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


Opening an image as a smart object1
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


Resizing a smart image
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%


Converting a layer to a smart image
Converting a Layer to a Smart Image

  • To convert a layer to a smart object


Placing a smart object
“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


Editing the content of a smart object
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.


Editing a smart object in its own file
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.


Replacing a smart object
Replacing a Smart Object

  • To replace a Smart Object:

    • Have a file to replace the object with

    • Layer>Smart Objects>Replace Contents…


Summary
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.

Rest of Today

  • Practice adding Smart Objects into a picture

  • In the homework section download the africa.7z file and extract the files.

  • Create an African scene using just smart objects. Include 3 animals.

    • 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
