"Warm-n-Cool" Filter

Two engineers and I have developed an image filter called "Warm-n-Cool". It can remove the influence of local colors and show the color temperature relationships of the light and shadow. Basically, it changes a full color image to a two colors (hues) only image. The two hues are orange (warm) and blue (cool). I have used "Warm-n-Cool" to filter my reference photos, and gain much better understanding the specific color temperature distribution across the image. In many cases, I can use orange and blue only to paint an entire painting realistically. The "Warm-n-Cool" filter is free for everybody to use. Please follow this simple instruction: Go to > Apps > Painter's Guide 3.1 > Load your image > Filter > Warmncool.

Digital Squinting


Life is short. How can we become good in painting QUICKLY? We all know we need to practice, but to accelerate the progress, my secret is: USING SMART TOOLS. The posted image shows that you can "squint" your ref photo digitally. Here is how to do it: Go to website) > click "Apps" > click "Painter's Guide 3.0" > load your ref photo > click "Filter" > click "Oilify". Now you have no worry you develop wrinkles because you squint a lot during painting time. I have quite a few apps on my website, which are free for you to use. I want to thank the engineers behind the screen for making these tools available. As a matter of fact, I have a workshop next month at the Scottsdale Artist School ( I will show you my techniques. Life is short. If you want to paint goodly (I mean well), I will teach you how to "cheat" correctly.

Cityscape Study


Master artist Hsin-Yao Tseng did a cityscape workshop here in Austin last November. I did this painting by using one of his reference photos. Combined what I have learned from Hsin-Yao and the color research I have been doing, I witness this painting gradually revealed itself in front of me. The color scheme is dominated by the warm and cool lights, while the local colors are rather subtle.
