Using image filters

Using the Built-in Filters

To best experience the image filters, you will open and edit a real photo image now.

1. Download your picture from your web page.
2. In your PaintShop window, choose "Open" from the File menu.
3. Locate the picture you just downloaded and open it.

The image should show up in its own window within the PaintShop window. As before, adjust the Zoom Level to your preference (If the control is not there, click on the magnifying glass to make it appear). Notice that you can edit and resize this image in exactly the same way as you did with the other image you just created.

1. Check the Color Depth by choosing "Image Information" from the View menu and looking at the figure next to "Max # of Colors".
2. If the Color Depth is less than 16 Million Colors, choose "Increase Color Depth" from the Colors menu and change it.

Now we're ready to try the built-in image filters. All of them can be found at the bottom of the Image menu, under "Special Effects", "Deformations", "Edge Filters", "Normal Filters" and "Special Filters".

Try at least 3 of the filters and save the results as different files using the "Save As" option. You will be submitting these at the end of the lab.

Creating a custom image filter (optional)

If you're interested in how filters work, try creating your own.

1. Select "User Defined Filters" from the Image menu.
2. Click on the "Help" button and read about how image filters work.
3. Choose "New".
4. Using what you learned in the "Help" section, edit the matrix of values to some new pattern and then press OK.
5. Click on "Apply" to try out your new filter on your image.

If you create your own filter, be sure to save the results and submit them for extra credit.
