My Dear Bee's I have been asked to please do something on the Arithmetic tool. Though this is a very interesting tool and I will encourage you all to play with it. It's a simple tool to use.

The Arithmetic tool gives you the effect of a double exposure. You will have the reflections of one graphic over another. You make the choice which one you would like to put over the top of the other. Granted many of the effects you can get you CAN do with using layers, however there are still some effects that can't be obtained without using Arithmetic. Using arithmetic is also a lot of fun and you can get some amazing results. It will depend on the two images that you choose as to how your final image will come out. The size of image #1 determines the size of your new image.

Lets Start out with what PSP had to say about this tool:

Paint Shop Pro sets the standard for affordable, professional image editing. Version 9 builds on Paint Shop Pro’s legacy of creative innovation with a new set of art media tools, professional photo correction filters, and precision graphic design capabilities to offer users limitless creativity. You can greatly reduce time spent on production tasks with Paint Shop Pro’s streamlined production tools. Edit photos, create graphics, draw, paint, and animate, all within a highly customizable workspace environment. Paint Shop Pro 9 provides advanced tools for advanced imaginations.

Combining Two Images

Paint Shop Pro can combine two images into a third image. The new image is the product of the color data from the two source images. The color data from the two images is combined on a pixel-by-pixel basis according to the function you select.

To combine two images:

Open the two images you want to combine.

Choose Image > Arithmetic to open the Image Arithmetic dialog.

Choose an image for Image #1 from the drop-down list. The size of Image #1 determines the size of the new image.

Choose an image for Image #2 from the drop-down list.

From the Function group box, select a method for combining the images:

Add Image 1 Value + Image 2 Value

Subtract Image 1 Value - Image 2 Value

Multiply Image 1 Value x Image 2 Value

Difference Absolute Value of (Image 1 Value - Image 2 Value)

Lightest Maximum of (Image 1 Value, Image 2 Value)

Darkest Minimum of (Image 1 Value, Image 2 Value)

Average (Image 1 value + Image 2 Value)/2

OR Binary Or

AND Binary And

XOR Binary And/Or

From the Channel group box, select the color channel from each image to use for combination. Mark the All channels check box to use all the color channels in both images. This will produce a 24-bit image.

In the Modifiers group box, choose modifier options. The modifiers are applied to the color values produced by the Function and the Channel selections.

Divisor This number is used to divide the color values. It can reduce the effects of the other selections.

Bias This number shifts each color value by a fixed amount. The number is added to the color value produced by the Function, Channel, and Divisor selections.

Clip color values This check box determines how Paint Shop Pro handles final color values greater than 255 and less than 0.

Clip Color Values
Value less than 0
Value more than 255

Marked
Value = 0
Value = 255

Cleared
Value = Value + 256
Value = Value - 256

Click OK.

Mathematically Combining Two Images

Paint Shop Pro can create a variety of effects using the Arithmetic effect, which combines two images to produce a third one that is determined by settings the user selects.

To combine images using the Arithmetic command:

Open the two images you want to combine.

Choose Image > Arithmetic to open the Image Arithmetic dialog.

In the Source image #1 and Source image #2 drop-down boxes, select the images to combine. The size of Source image #1 deter­mines the size of the new image.

In the Function group box, select a method for combining the images. The color data from the two images is combined on a pixel-by-pixel basis according to the function.

Function
New Color Value Equals

Add
Image 1 Value + Image 2 Value

Subtract
Image 1 Value - Image 2 Value

Multiply
Image 1 Value x Image 2 Value

Difference
Absolute Value of (Image 1 Value - Image 2 Value)

Lightest
Maximum of (Image 1 Value, Image 2 Value)

Darkest
Minimum of (Image 1 Value, Image 2 Value)

Average
(Image 1 value + Image 2 Value) / 2

Or
Binary Or

And
Binary And

From the Channel panel, select the color channels to combine

Mark the All channels check box to use all the color channels in both images. This will produce a 24-bit image.

Select a specific color channel for each image to produce a grayscale image.

Set the Divisor and Bias modifiers. The modifiers are applied to the color values produced by the Formula and the Channel selections.

The Divisor number is used to divide the color values. It can reduce the effects of the other selections.

The Bias number shifts each color value by a fixed amount. The number is added to the color value produced by the Formula, Channel, and Divisor selections.

Mark or clear the Clip color values check box to determine how Paint Shop Pro handles final color values greater than 255 and less than 0.

Check box Setting
If value is less than 0
If Value is more than 0

Selected
value = 0
value = 255

Cleared
value = 256 + value
value = value - 256

Click OK.

Now your asking with a frown on your face and hand to your head. What does all this mean?!

**giggles**

Let me see if I can clear this up a little for you and put it in more simple form.

Your going to need two Images for this Lesson. Here are the two I used for this part of this lesson:



As you can see I have a Tube for one of my Graphics and a Photo for my second. Now I have to decide which will be the top and the bottom graphic.

Lets go to Image / Arithmetic

You're going to get a window like this:



Now you can see there are a lot of choices we can make but we are going to start out simple and then you can play with it a little more.

Here are the settings I've used for this one:



As you change the numbers in the Bias it will change the amount of black and white you have in the Blend.

Here's another example:



As you can see now we have more white in our graphic.

I want you to play with this.. and show examples of what you came up with.

Now lets make a Tag out of this:

Open a new image 500 x 500 transparent background

flood fill with a color of your choice

right click on your flood filled layer and go to New Mask Layer/ From Image

Here's the mask I used:



Apply Effects/ Plugins/ Xenofex 1.0/ Distress

Settings:

Edge 20
Irregularity 90
Click the check

Now Activate your graphic and add Effects/ Texture Effects/ fine leather:

Settings:

Angel 210
Blur: 6
Transparency: 247
Number of furrows 14
Length of furrows 6
color.. your choice
Click ok

Now Add the Same Mask and Stress to this Graphic as you did with you new Background.

This is what you will have:



Now copy and past this as a new layer over the top of your background so now your going to have this:



Add new raster layer and drag it to the bottom

Flood fill with a color of your choice

Crop off the extra and merge / merge flatten

Now create your own frame for your project:

More Examples of the effects you can get with this tool:





ASSIGNMENT

1. A finished tag using the Arithmetic tool:

2. 3 Examples of what you came up with after changing the settings in the Arithmetic Tool.
