A Musing 5b: It's Just an Illusion (Part 2)

Let's talk some more about optical illusions.  If you missed the first part of this series (and this may be the last part, unless I think of something else worth saying) you can catch up here.  That's not required reading to understand this part, but it may be of interest.  So, illusions! Fascinating things.  In the previous part I discussed how illusions help us understand art.  This time I'll be looking at how they can also make the artist's life hell by lying about what we're seeing when we are trying to reproduce it.  This issue doesn't effect all artists - some people just have the natural power to overcome at least some of these illusions, and for others you can either learn tricks to get past them, or use "mechanical" means to do the same.  That is not what this post is about though.  I'm not going to go into every optical illusion that causes problems, just a small number of prevalent ones or I'd be here all week.

Interlude: Thoughts on the Blog's Future

So I've been debating with myself for some time over certain aspects of the Blog (there's probably a dirty pun there if you look hard enough). Every post so far has some images, and those images are either exclusively by me, or reference for something done by me, and this was fully intentional.  This has its advantages; after all, this is an art blog, but also some disadvantages.  For one, it means that I can only post about subjects I have images for, rather than any old thing, and for another it means I can only post as often as I have work to show.  Sometimes though I want to talk about other things, sometimes art related, sometimes just random things that I want to vent about.  Sometimes I want to write something that may require images that I didn't take, or paint, or use as reference.

I think this post is only the third time I've written written a post with no image content, although this one at least has an icon, the others didn't.  Interested in what I have to say rather than show?  Carry on then dedicated follower (you mad crazy fool).
