Students will learn to edit ripped, torn, or damaged images using the amazing Clone Stamp Tool! This tool can also be used to digitally remove or replace unwanted pixels from your image, like the image above where the brush and the rope in the background have been removed completely as if they were never there!
The clone stamp tool works by sampling pixels (picture elements) or the tiny dots that make up your photoshop file.
Images that we find on the web are typically low resolution (72-96 DPI- dots per inch), which means that the file size of the document has been optimized (made smaller) so that it can be viewed online by anyone using any web browser or even a slow dial-up modem (yep, some people still use’em).
By choosing File-Save As from the File Menu, you may save a document in Photoshop as any number of different file types. A GIF (graphic interchange format) can be used for something you wish to save for higher quality, a TIF (tagged image file) is another favorite for higher file sizes. We will usually save our images as either a PSD (photoshop document) or a JPEG ( named by the Joint Photographic Experts Group). PSD’s are large files and must be optimized by the artist before used for the web, but can be kept as larger files for print.
Images, such as photos taken by our digital cameras in class, will be a much higher resolution like 300 to 600 DPI. Photoshop is a raster based program and keeps track of various pieces of information about all of the dots (pixels) in your image, such as hue, saturation, and lightness. You can imagine how quickly these files become huge with more and more pixels jammed into each inch as resolution increases!
In the example above you can see the individual pixels that make up the larger image. All photoshop documents (PSD’s) are made up of such tiny squares.
A vector based program like Macromedia Flash or Adobe Illustrator uses mathematical formulas to keep track of its files, saving lots of space and allowing each file to be re-sized from a six-inch print to a wall-sized image without any loss of a clean edge. In the image above, notice the edge of the letters, where the image is a vector file, there is no loss of image quality and the edge is perfectly clean and smooth since the image is not made up of pixels.
Using the Clone Stamp Tool (S), you will sample from one area of the image by Alt-clicking (holding down the Alt key while you click w the mouse) then use the Clone Stamp Tool to repair the rip in an old photograph.
His the quick key S to select the Clone Stamp Tool, and play around w/ it until you feel comfortable with it, then fix the tear in any old photograph.
Now check out the same image after having been repaired, sharpened, and adjusted…
Use a search engine on the Web to find a torn/damaged photograph using the search words “torn photo”. Be sure to change the Size (Large) of the images you are searching for in the settings so that you can work on higher res images…
Edit the torn photo in Photoshop using the Clone Stamp Tool (S) until you can no longer see any damage or signs that there was damage.
Done? Choose Image- Canvas Size then double the width (only the width!) of the canvas. Be sure to anchor the image to the right using the white boxes w arrows in them.
Now choose File- Place- and find the original image that you downloaded from the Web, place it to the left of your repaired photo. Be sure that they are the same size.
Making a Levels Adjustment: Make sure the repaired layer is selected, then choose Image- Adjustments- Levels (or if you want to be cool, just hit Control + L on your keyboard). Move the black and white sliders (see the image below) until they just touch the edges of the “black mountain” AKA the Histogram (a graphic representation of the light and dark pixels in your image).
Now that you have the Before and After images side by side, you can see how good or bad your repair job is!
