Sketching with 2B and Oily Variable Pencils in Painter

Image
I tried out doing a digital pencil sketch using a Intuos 3 tablet and Corel Painter X. The experience and result are almost as good and as satisfying as doing it on real paper and pencil as shown in the sketch below. The steps I did are described below. Start up Painter and open up a photograph. Select File > Quick Clone . A clone of image window is created . In the Brush Selector , select the Pencils brushes' 2B Pencil variant as shown below. Now choose a dark grey Main Color  for the 2B Pencil in the Colors , Mixer or the Color Sets palettes. Zoom in closer in the clone window as shown below. On the keyboard, press B to activate the Brush tool. Use the tablet and pen to sketch over the clone image. Outline the object and block out the positive spaces and negative spaces. Note: the 2B Pencil variant uses a Buildup method i.e. the color values will darken as you repeatedly sketch over the same area . Now use the Pencils' Oily Var...

Corel Painter can be used to isolate objects from photographs as shown below. The result can be even better if a Wacom tablet is used to paint away the background. An example of an isolated image on white background is the tiger image below.

Removing the virus VirusRemoval.vbs

I found my home computer and a few thumb drives infected with this virus. The only indication that something was not right was that whenever I plug in my multi-card reader into my USB port, a message will pop up saying that the drive is empty or something to that effect; or in other words, something was trying to write to my multi-card slots. So I examined my thumb drives and SD cards and found these hidden files VirusRemoval.vbs and Autorun.inf on it. Luckily this virus doesn't do anything more damaging than changing the home page of Internet Explorer and propagating itself onto portable drives. And I was able to remove it with a few simple steps. Symptoms of the virus: If a computer is infected, then the following are true. The file VirusRemoval.vbs can be found in the Windows system folder c:\Windows\System32\ as a hidden, readonly file. The HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\WinLogon\ registry entry will be set to start up the VirusRemoval.vbs scr...
