I do hard edge a lot and was hoping I will learn some technique by watching this video, but sorry to say, the technical part it is utterly disappointing - and frighteningly not accurate. The teacher says that no matter what you will have brush marks, so not true. Only if you use as thick paint as demonstrated and try to make it one layer or two. He says about the value of patience but displays not much of it. To have a flat coverage you add medium thinner to the paint, and apply lightly in layers. Yes, patience is important, some colors, especially yellow, require many layers, sometimes I do the-twelve layers, to get proper density of color and no strokes. There is also a fantastic quality paint Golden SoFlat Matte Acrylic that is already perfect consistency and leaves no paint brush marks. Also there is no need to suffer with cutting your own flexible tape, there are several brands of flexible tapes for curves available on amazon. And waiting half hour for the medium to seal the edge? Really ridiculous. There are way better options. Search here on youtube. For example Golden Fluid Matte Medium works and dries instantly.
Great explanation about Simultaneous Contrast. The teacher is clear and demonstrates with examples all the way. I have been looking for different videos to understand these concepts better, and this is the best video I found. Thanks for posting it!
At the time 37:00 I had an epiphany,- the Law of Diminishing Returns applied here. Instead of outlining your shape with tape, carefully cut it out of a thick glossy paper (e.g., bristleboard) or plastic. Now fasten the outlined shape using hot glue applied close to the perimeter of your shape. When you press it down on the surface, you want glue to bleed out everywhere along the inner perimeter. Let cool. Remove the bled out glue with a knife. Now fill the shape with paint using whatever tools you are accustomed to. Let dry. Cut around the perimeter of the mask, and peel it off. Reserve the cut out shape for later masking when you are painting around it.
