SLP Curriculum Guide #16: Deform Tools


The 'Deform Tools' are, for the most part, tools used to correct or fix photographs in particular ways. In brief, the tools we will cover in the next series of Guides include the following:

Deform Tools Icons
  1. The Deform Tool allows one to change the perspective of a selected or existing selection. A very versatile tool with unique options. Note: In PSP version X, the Deform tool is not visible initially and has been replaced with the 'PICK' tool which works exactly the same as the Deform Tool.
  2. The Straighten Tool straightens photographs so the perspective is looking straight at the object such as a building rather than looking at the object which is somewhat skewed.
  3. The Perspective Correction Tool fixes the perspective of objects that appear out of perspective to one of in perspective such as a building (initially looking down one side to looking square onto it).
  4. The Mesh Warp Tool is a very unique tool which uses a grid to fix perspective of sections of a photograph and has a number of unique options.

We will begin with the Deform (Pick) Tool and explore its options. Included in this guide is the tip for displaying it (or any undisplayed tools) using the Customize option which allows newer versions to display some older versions tools.

GUIDE #16: DEFORM (PICK) TOOL

  1. To Display Tools that have been hidden by a PSP version:
    • Click on View || Customize
    • In Customize Window, Categories box (on left) select TOOLS
    • In the Commands: box (on right) scroll to tool wanted to be displayed on the Tool Bar.
    • Select tool, drag from Commands Box to an open area on the Tool Bar.
  2. When working with a photograph or image, duplicate it (Windows || Duplicate or [Shift + D].
  3. When the Deform (Pick) Tools is selected, the picture will display a square box around the picture and each corner, center of each side (top, left, bottom, right), and the center of the picture will have handles or nodes visible.
  4. By grabbing a handle and dragging it one can deform or transform the image.
  5. There are four (4) modes (ways) to deform a picture: Scale, Shear, Perspective and Free.
  6. There are two general ways to select a mode: (1) Use the MODE Option (and select a mode) or (2) Use either or both the Shift Key and/or Control Key while grabbing and dragging a handle.
  7. A great way to learn using this tool is to just try it, experiment and play around.
  8. When using this tool you want to often UNDO using [Ctrl + Z] so that you can correct back to a previous image.

SCALE

Using 'Scale' allows one to resize the image in scale or perspective and in various ways.

Original

The Original Picture is an 800 x 600 photograph. To illustrate the scale for Corner Drag and Top Middle Drag, I placed it on a Dark Blue layer.
Corner Drag Diagonally
Grabbing any corner and moving it inward will reduce the size of the picture (in perspective). If angled corner to corner one can keep the original perspective. One can also create a perspective square of the picture.
Top Middle Dragged Down

Grabbing a middle handle and dragging inward one can create a panoramic like photograph.

Often one will use the eye to maintain a perspective. However, one could set up a grid (another guide lesson later) to preserve the true perspective of the photograph by using guide lines. Also, there are many different ways to create perspective using the Pick tool including developing Perspective shadows for objects, creating perspective pictures which can be seen as 3-D pictures and other unique ways to use the Pick Tool and its various options.

SHEAR

'Shear' (either selecting it in the Mode box or using the 'Shift Key') creates an image that is sheared or skewed. The direction of the shear is dependent upon what handle is used and what direction the handle is dragged.

Top Left Corner Dragged Down

Using the Top Left Corner Handle and dragging downward, one creates the illustrated Shear Picture. Experiment with other corners for practice.
Middle Handle Dragged to the Right
Grabbing the Top Middle Handle and dragging right ( and repositioning or moving the image to the left) one creates the illustrated Shear. Experiment with the sides and dragging down and up for practice.


PERSPECTIVE

'Perspective' (either selecting it in the Mode box or using the 'Control Key') creates an image that becomes in perspective dependent upon which direction the handles are dragged. The only available handles are those in the corner or in the middle to move.

Top Left Corner Dragged Down

Using the Top Left Corner Handle and dragging downward, one creates the illustrated Shear Picture. Experiment with other corners for practice.


FREE

'Free' (either selecting it in the Mode box or using the 'Control Key' and 'Shift Key' together) creates an image that becomes in perspective dependent upon which direction the handles are dragged.

Various Handles Dragged

Grabbing a corner handle allows one to move it almost anywhere wanted. Grabbing a middle handle allows one to move it down or sideways. The resultant image will appear very skewed.


COMMENTS and EXERCISES

Using the Deform (Pick) tool allows one to resize the perspective of a picture. There are various ways to create very interesting pictures using different combinations of this tool. To explore the use of the Deform Tools and ways to create interesting pictures check out this tutorial and related tutorials:

Create your own pictures using the Deform Tool and its options. Enjoy.
