Anyway, I have purchased Adobe Creative Suite 6 Master Collection Student & Teacher Edition. I will install it when I recieve my New Tablet PC. As suggested by my friend here online,I would tweak the settings and see if Photoshop can deliver the screen display clarity which I desired? Then I would test some more aspects of Photoshop. As declared earlier,I would then see if I really need to buy the other two softwares that is;OpenCanvas and TV Paint Canvas. These three (TV Paint,Photoshop and OpenCanvas) are the ones who have passed the preliminary tests during the tenure of their free demo for a month or so.I tried allmost all Sketching softwares for windows OS. Rousing said on some other thread: I don't care if I was not aware of advanced features of Photoshop before buying it. Logic is simple:If you can do basic stuff with it,you select it as a first round selection in a competition. Advanced feature would be tested in second round. I don't like your attitude. Simple:If I fill colour in a space and if it does not fill properly at the boundries,tell me a single reasion why I should know the advanced features of Corel Painter and why should I ever buy it??????? You have to know about the advanced features only during second or third phase round of the competition within softwares. A light advanced feature which Designers really can really take advantage of is the mirror symetrical painting.Designers don't use all of the tools and features available in photoshop which is used by photoeditors,its limited in design applications.Symetrical painting is I think available in OpenCanvas,but I think its not available in Photoshop OR TV Paint Animation.
