Corel painter 2015 review is the latest release of one of the world's most popular digital painting programs. It is a full-featured painting and drawing application that works on most platforms, from Windows to Mac, Linux, Android and iOS. It is aimed at amateurs, photo painters and art enthusiasts who want to use an intuitive and powerful tool that will let them produce high quality artworks.
This new version introduces a whole host of innovations including Particle Brushes that flow, spring and gravitate on the canvas from a central point creating stunning effects. There are also two new tools for mirror and kaleidoscope painting, a vastly improved photo painting engine, better support for Wacom digital drawing tablets, real time effect previews, and more.
The user interface has been streamlined to make it more intuitive and easier to understand. The application is based on layers which can be altered and manipulated to achieve the desired results, and the brushes have been modified to make them more responsive, especially when used with the jitter settings that enable the brush properties to react to an audio waveform, as demonstrated by Karen Sperling in her video below.
Corel has included custom palette arrangements that are designed to save time and give you quicker access to the tools most suited to each type of work. For example, there is a set for 'Photo Art' which contains all the tools most suitable for that kind of work, and there are also arrangements that are suited to specific styles of painting such as 'Watercolor' or 'Illustration'.
