Photoshop – Smart Objects Computer Information Technology Section 7-8
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 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 • 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 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 • 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 • To convert a layer to 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 • 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 • 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 • To replace a Smart Object: • Have a file to replace the object with • Layer>Smart Objects>Replace Contents…
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
