GIMP: Chapter 7: Filters and Effects

PART 1: READ Chapter 2 in the GIMP book, then:

1. Answer all questions below, briefly but completely.
2. Change the color of the answer to BLUE.
3. Copy this information and paste in a new post in your DIGITAL GRAPHICS blog.

NOTE Regarding the Xtns menu: In Chapter 7, the author discusses the difference between FILTERS and EXTENSIONS found in the Xtns menu. The Xtns menu does not exist in GIMP any longer; the items have been moved to other menus.

1.      What is a filter? Is a general term for anything that can operate on an existing image

2.      What is the difference between a TOOL and a PLUGI-N? tools can respond to clicks in the image window. PLUGI-N can only make adjustment within the plug-in's own dialog.

3.      What is the purpose of motion blur? Makes a blur in only one direction, given an impression of movement.

4.      Briefly describe the purpose of the following ENHANCE filters: ·         Antialias looks for jagged edges and tries to make them look smoother. ·         Despeckle is used to remove small elements of “noise” from an image. ·         Destripe removes vertical limes that are left by some older scanners. ·         NL Filter Is a combination of smoothing,  despeckle, and sharpen in one filter.

5.      Briefly describe the purpose of the following  DISTORT filters: ·         Blinds makes it look like your image is painted on venetian blinds, and you’re adjusting the angle of  those blinds. ·         Curve Bend is useful for changing the shape of nearly any layer. ·         Engrave creates the black and white engraved look that you sometimes see in old illustrations. ·         IWarp (Interactive Warp Filter) let you change the images giving it deformities.

6.      Briefly describe the purpose of the following  filters: ·         Polar Coords wraps an image around a point at the top or bottom center. ·         Ripple makes an image look as though it’s being viewed through water waves. ·         Lens Flare is a way of putting a bright flare of light into the image. ·         Supernovais similar to Lens Flare but it makes flares with spike of rays. ·         Drop Shadow makes a shadow tilted at an angle to show perspective. ·         Glass Tile makes the image look like it’s been view through a wall made of many glass bricks, each of which refracts light a little differently,

7.      Describe various ways the EDGE filters are used in GIMP: Difference of gaussian, Edge, Neon, Laplace

8.      What does the FILMSTRIP filter do? Combines the layers in the image into a single image that looks like a strip of 35 mm film

9.      List and describe 5 filters found in the ARTISTIC filters group: a. Apply Canvas  gives a canvas-like texture to the image b. Cartoon simplifies colors and adds black outlines near edges with intent of making a picture look like a hand-drawn in inked cartoon. c. Predator turns image into something that should remind you of a video game of the 80’s. d. Softglow gives a “bathed in light” impression. e. Weave gives an effect that the image has been woven onto a basket.

10.  What does the FRACTAL EXPLORER do? It makes fractal patterns.

11.    What does ALPHA TO LOGO do? It creates interesting effects from a text layer.

PART 2: GIMP PROJECTS: Be sure to save these images in your GIMP folder before inserting them in this document.

1.      WARP text: 1.      Create a new GIMP image that is 600  X 400. 2.      Use the paintbrush, gradients, etc. to create a lovely background. 3.      Click on the text tool (letter A), and change the font, color (to coordinate with the background), change the size to fairly large (at least 200). 4.      Type your first name in the text box (this creates a new layer with your name on it). 5.      Warp the text: Make sure you are on the text layer. Now: FILTERSàDISTORTSàBEND CURVE. Drag the base line up/down to make it wavy. Click on PREVIEW ONCE to see the text distorted. When the text is distorted the way you want, click OK. 6.      You can also add a Drop Shadow if you like: FILTERSàLIGHT AND SHADOWàDROP SHADOW. 7.      Crop the image if needed, then save the image. 8.      Insert your warped name image here:

2.      Filter Car Image: 1.      Go to the web site for this book: http://gimpbook.com 2.      Look through the menus on the left to see the supplemental information provided for you about the book. 3.      Click on the PHOTOS FROM THE BOOK link, and scroll down to see the images for Chapter 2. 4.      Download and save the red car image from Chapter 7 (or get a car image from Google that you like) 5.      Try at least TEN different filters on the car image. Try to make the images as different and interesting you can.  Save each version with an appropriate name. 6.      Insert the 10 filtered car images here:
