Part 2


Photo Enhancing Features and Filters of Photoshop Elements

Use Enhance --> Auto Level + Auto Contrast


Use Enhance --> Adjust Lighting --> Fill Flash


Use Filter --> Render --> Lighting Effects followed by Crop

or, even more dramatic,


Use Enhance --> Adjust Color --> Color Variations


The imperfections on older or worn scanned images are readily removed. Consider:

Simply blurring to remove dust and scratches ruins the eye sparkle and facial features. So we use "layers" to store the faces and blur the rest.

  1. Use Clone Stamp tool to clean up major flaws, particularly along bottum.

  2. Create a "Mom" layer, use lasso tool to copy her face from Background to Mom

  3. Create a "Dad" layer, use lasso tool to copy his face from Background to Dad

  4. Use Blur Filter repeatedly to eliminate dust specs.

Another nice image enhancing trick for producing card scenes, invitations, etc. is "Feathering".

Consider our last three Christmas cards:

How is feathering done?

1. Select the image to be feathered and crop appropriately

2. Select a selection tool [rectangle, oval, or lasso]

3. Enter a pixel value from 1 - 250 in the feather box [typically 50 - 100]

4. Select the "Selection Tool Brush" from Toolbox and select a soft edge brush from menu

5. Now use selection tool to select feather boundary in image

6. Select "Copy" from Edit menu

7. Select "New from Clipboard" from file window. A new feathered image will appear.


Results:

Feathering with Rectangular Selection

Further feathering with Oval Selection


Problems of achieving the desired image may be solved by the photo editing process of merging elements of two or more images. Consider family portrait from last year's Christmas card:

Here are two of eight or so images trying to get four grandchildren to pose:

The problems are obvious. The solution is to paste Ray's head from the second photo into the first.

Results:



Finally, Elements provides many fancy type styles through Layer Styles






F. Interactive 360° Images - QTVR

Apple introduced a panoramic image file format called QuickTime Virtual Reality (QTVR) which allows the user to view a scene in full 360° field of view and zoom in and out on objects of interest. It has become an industry standard and plug-ins are available for browsers on both Mac and PC platforms.

QTVR Navigation Rules:

1. Position cursor over image, press button, and move left, right, up, & down

2. To zoom in, use <Shift> key

3. To zoom out, use <Control> key


Examples:

Let's look around my front yard:


Let's look out the windows of the sunroom:



Steps to Produce QTVR Panoramas

1. Mount a reasonably good digital camera on a tripod with a degree scale

2. Take 12 pictures at 30° intervals

3. Download images to folder (e.g., "BackYard")

4. Open a "Stitching" program such as Canon's PhotoStitch

5. Transfer the 12 images into PhotoStitch using the Open button

6. Click Arrange and select "360 Degrees"

7. If you have taken pictures in CCW direction, click Switch

8. Click Merge All

9. Once merging is successful, click Start

10. Save QTVR file to BackYard.qtvr
