A. Cropping with Perspective (CS5)
The Crop tool has an option that lets you transform the perspective in an image. This is very useful when working with images that contain keystone distortion. Keystone distortion occurs when an object is photographed from an angle rather than from a straight‑on view. For example, if you take a picture of a tall building from ground level, the edges of the building appear closer to each other at the top than they do at the bottom.
Steps to transform perspective
- Select the Crop tool.
- Drag the cropping marquee around an object that was rectangular in the original scene (although it doesn’t appear rectangular in the image).
- Select Perspective in the options bar, and set the other options as desired.
- Move the corner handles of the cropping marquee to match the object’s edges. This defines the perspective in the image, so it is important to precisely match the object’s edges.
Do not move the center point of the cropping marquee. The center point needs to be in its original position in order to perform perspective correction.
- Do one of the following:
- Press Enter (Windows) or Return (Mac OS),
- Click the Checkmark button in the options bar,
- Double-click inside the cropping marquee.
- To cancel the cropping operation, press Esc or click the Cancel button in the options bar.
B. Image Adjustment Options
Quick Fixes in the Image Menu: these can be good starting point adjustments.
- Auto Tone
- Auto Contrast
- Auto Colour
Black and white type imagery can be switched to greyscale for a more accurate visual representation of the work. (This will remove yellow tones from photographs).
Image > Mode > Greyscale > (click ok).
Brightness / Contrast
This can be used to bring out more definition among the elements in the work (if images look washed out).
Used to adjust the values (highlights, midtones, shadows) in an image. Will also adjust brightness and contrast in turn.
Great for slight adjustments in colour images.
Burning / Dodging
This is a great way to clean up backgrounds (easiest with greyscale areas). It can help get rid of unwanted shadows, rips, paint marks, fingerprints, etc.
Be sure to use a large, soft edged brush, with Hardness set to zero, and exposure between 40-60%
Burning: makes darker
Dodging: makes lighter
