What does Program do?

Well, you can use Photoshop to "alter" images like photos.

Altering an image includes doing such things as

Editing
    - Contrast   
    - Brightness
    - Invert
Compress image
   - Dither – such as 2*2 matrix or 4*4 matrix
   - Lookup – create lookup Table
Filter
   - Blur,Sharpen, Border, RGB Adjust, Gary

 

 
Contrast [demo]

Contrast is easy to understand visually.  Artistically, contrasting colors are colors that are opposite on the color wheel -- colors that are opposites.

 In a high contrast image, you can see definite edges and the different elements of that image are accented.

In a low contrast image, all the colors are nearly the same and it's hard to make out detail.

Brightness [demo]

lThe Brightness of an image may be thought of as the overall luminance of every pixel. 

To increase the brightness, all that needs to be done is to add the Adjustment value to every color channel.  The only difference in darkening an image is you subtract the value.

 

Dither [demo][technique]

The main strategy is to replace a pixel value by a larger pattern, say 2×2 or 4×4 binary matrix, such that the resulting black and white dot pattern approximates shading.

 

Filter - Blur [demo][technique]

remove fine detail from the image by using 3 * 3 matrix

Filter - Sharpen [demo][technique]

enhance the edge of the image by using 3 * 3 matrix

Filter - Border [demo]

Add a border around the image, the size of border is depends on the user input for each side (left, right, bottom, top)

 

Filter - RGB [demo][technique]

increase or decease the value of RGB value.

 

Look up Table [demo][technique]

There are two methods ( convert 24 to 8 bit and medium cut algorithms ) to compress the image.
