Hello everyone, I'm Wei. I'm delighted the whole course is now fully online, and I hope you all paint happily throughout your learning! During this course I've also seen several questions students commonly ask, so I've gathered them here to answer one by one. First, the most common question: "If the software I use isn't Painter, will it affect my learning?" Before answering, I thought a while about how to reply, and decided to answer directly: "Yes, it will!" With different software, it's impossible to say there's no effect at all. But the part affected is "tool usage". It's the same reason a drawing made in pencil feels different from one made in watercolor. But painting concepts — how to use color, how to light a scene, how to draw faces, and so on — don't change at all with different tools. Comparison of a portrait before and after using Painter's brush knife tool Take this gender-swapped Lü Bu from our class demonstration as an example. On the left is a screenshot of the portrait as I first finished it; on the right is the curly hair created by brushing over the base with Painter's distinctive "brush knife," then lightly refining — and that brush knife is a tool unique to Painter. Photoshop has similar brushes (such as the "ribbon" brush in Xuego Yang's brush set), but the feel in use is still slightly different! So, do the concepts of painting hair change with different software? No, they don't — the concepts stay the same! To sum up the question "If the software I use isn't Painter, will it affect my learning?": My answer is "Yes!" — but what's affected is "tool usage", while learning the "painting concepts" is unaffected. Students can start with the "trial version" and paint with Painter first. If it really feels good to use, then consider whether to purchase and continue. Personally, I believe what matters in painting is the concepts; as for tools, whatever feels smooth in your hands is right. Any software, tool, or brush is fine! I hope this answer helps, and you're always welcome to raise any questions while learning. Thank you, everyone!
