Head Drawings, Oil Sketches, and Quick Poses - Page 12 Gesture Drawing Notes Thank you for all of the support. Here's is a lecture on Gesture Drawing. I've wanted to write down my conversations with students for a while. This pretty much my first day lecture on setting up gesture drawings and the function of the time constraint. Notes on Gesture DrawingI will talk about the purpose of gestures. Usually the first mistake I see from students is the placement of the AC being too far out and the arms being drawn to far away from the ribcage and shoulder girdle. Bummer! Picasa’s Creative Kit is Gone If you click on the button in Picasa to ‘Edit in Creative Kit’, today this is what you’ll see: What was Creative Kit? If you don’t know what Creative Kit was, here are some articles I wrote about the useful tools in Creative Kit that do not exist in Picasa3 proper. Now they don’t exist for Picasa/Google+ users at all! Picasa Tip: Speech Bubble on Your Pictures (put text into a speech bubble right on your picture – using Creative Kit)Picasa Tip: Merry Christmas Photo! What is the Replacement? If you have joined Google+, there is a new Edit button when you’re looking at a single photo. Are there other Options? The Creative Kit button began as a plugin to the Picnik photo editing website that Google bought a few years ago. Picmonkey.com has it’s own look and feel, but seems to include all the features you could possibly want for editing, enhancing, and embellishing your pictures. Why did Google Make this Change? We REALLY don’t know! All comments are welcome! p.s.
Light and Color Table of Contents Back to Index Introduction This tutorial is about color, which is no doubt a very important aspect of computer graphics. First is explained how light is built up and why we actually see different colors. Then a some color models are explained: first the RGB color model used by computers, and examples showing how to do color arithmetics in RGB, and then the more intuitive HSL/HSV models are explained. Then code is given that allows you to convert between color models, for example to allow a user to pick a color using the HSV color model and then convert it to RGB so the computer can use it, or to create rainbow gradients, or to change the color of images. Light Before starting about color models, it's important to know how the human eye and brain turn light into color. Light itself is an electromagnetic wave. Monochromatic light is light made up of one single pure frequency (this is certainly not the general case, most light you see is multichromatic). The RGB Color Model

Picasa tonal value Painters do not have the apparatus problems of a photographer, but they do face a similar value design problem: anchoring the middle value of a painting in a way that communicates the intended feeling of light or dark without sacrificing a complete representation of the tonal range. Our visual system naturally adjusts to the average luminance in our environment to produce the best visual representation. Because this adaptation also affects the appearance of any physical gray scale, the key to the value design of a painting lies in the distribution of gray values across the luminance range. What should this distribution look like? The CIELAB L* scale, which is a benchmark measurement of surface reflectance and the vertical scale used in the artist's value wheel, represents the basic reflectance range; this is overlaid (in orange) with the value range used to describe paints in the guide to watercolor pigments. Creating a Value Scale (Grayscale). 1. a naive value scale 2. 3. 4.
Selective Colorization Text and images Copyright (C) 2002 Eric R. Jeschke and may not be used without permission of the author. Intention In this tutorial I will explain how to convert a color photograph to a B&W one with color restored to selective areas. The basic technique is to duplicate the color photograph, convert the duplicate to B&W, and paste it as a new layer on top of the color image. Giving credit where credit is due: I did not come up with this method. The Procedure Here is the original example image, loaded into GIMP. Step 1 Duplicate the image (Ctrl+D). In this example, I tried the channel mixer, but ended up in this case preferring a simple conversion to grayscale (Image → Mode → Grayscale), then back to RGB. Step 2 Open the Layers dialog (Ctrl+L). Step 3 Go to the B&W image and select all, then copy (Ctrl+A then Ctrl+C). Step 4 In the Layers dialog, right-click on the B&W layer and select “Add Layer Mask”. Step 5 Make sure that Black is selected as the foreground color in the toolbox. ). Step 6 Step 7

Article by: Mateusz "seir" Piaskiewicz Composition in Level Design When designing a level you're able to freely compose your virtual environment with any objects you want. When you should care about composition? When and where you can apply composition rules: Environment Composition - Big picture, everything that the player sees, both visual and gameplay areas. There's a thin line between composing everything you can and imitate nature or natural mess. Composition Basics Composition is an arrangement of scene elements. The opposite to composition is chaos. Composition Layers Composition can be divided into three main sets of layers: Foreground, Center of Interest and Background. Foreground Layers Layers that are the closest to the observer.
