Started a bit late this morning, but got everything done that I wanted to do.  For business study, I watched more podcasts from the Art of Photography.  The first one was on handheld light metering.  I don't have a light meter but I can see that it might be a good investment in the future.  A light meter helps you decide how to arrange your aperture and shutter speed.  My camera has a built-in light meter in it, as probably does yours.  When this is the case, the camera "decides" automatically on the shutter speed and aperture.  Again, that's not something I have control over in my point-and-shoot but it is something to be aware of.  The other two podcasts I watched were about lenses.  All cameras have lenses, and most actually have more than one inside. On an SLR you can change the lenses to suit your needs.  My camera doesn't have this option, but it does have settings that simulate different lenses.  I don't know if these have problems with distortion or not, but I expect they would because all lenses cause some type of distortion.  The trick is to get the distortion you want for your particular photo.  These podcasts make me really want an SLR!  But that is not an option at the moment and I can live with what I have.  I haven't always been lucky enough to have any camera at all, so I can't really complain.

In my design book, I studied space.  I actually started studying the chapter a couple of days ago but didn't finish it until now.  There is a lot of wordiness that I didn't understand in this chapter, but I understood as soon as I saw the picture illustrating it.  Unfortunately, I can't show you the pictures from the book, so my words will have to do.  There are two major types of space in two-dimensional art: decorative space (flat-looking surface) and plastic space (looks like it has depth).  Plastic space is further divided by shallow space and deep or infinite space.  Shallow space looks like the picture has some depth, but not very much. The artist might have manipulated some tricks to make the image look flat.  Deep space looks like how we would actually see something in the real world (again, the artist uses tricks to make us think that it is as we would see it) and infinite space is just what it sounds like.  There are spacial indicators.  Sharp detail looks close to us, and diminishing detail looks far away.  Larger items appear closer than smaller items.  The position of a shape can make it appear closer: the horizon line is usually at eye level, so shapes below that on the canvas appear closer than shapes above it.  If an item is overlapping another item, it appears closer.  Transparency can be used with overlapping items to make them appear closer.  Interpenetration is when planes or objects pass through each other, and depending on what is pictured, can create shallow or deep space.  Fractional representation, which is seen in ancient Egyptian art, is when we picture a subject using those parts that best represent it in our heads.  For example, in Egyptian paintings the head is a side view while the eye is full on, the torso faces forward but the hips and legs face the side.  Converging parallels is when two sides of an object, which we know to be parallel, have sight lines pointing toward the same vanishing point.  Linear perspective is a way of representing sizes  and distances of objects in space.  There are three major types of linear perspective: one-point, two-point, and three-point.  One-point perspective has a single vanishing point in the picture, and was used frequently in Renaissance art.  Two-point perspective has two vanishing points, usually located off the canvas.  A view of a city might be a good example of two-point perspective.  Three-point perspective is used when an exaggerated view is pictured.  This can either be bird's-eye view or worm's-eye view.  There are formulas for making sure that shapes in the picture will be spaced in a way that seems to suggest distance to our eyes, which I won't get into because there are so many of them.  There are some disadvantages to linear perspective: it does not actually show things as we see them, you can only see things from one position in space, it can be monotonous, and the items pictured are distorted.  There are other projection systems as well.  Oblique projection does not have vanishing points, but does show a the side as well as the front of a shape, with the side at a 45 degree angle.  It is used by engineers and architects.  Isometric projection shows two sides of the object, both at 30 degree angles, as well as the top.  Again, there are no vanishing points.  It is used by drafters.  Orthographic drawing, all objects are drawn perpendicular to a base line.  It is used in engineering and industrial settings.  Reverse perspective is seen in traditional East Asian art, in which the back of objects are wider than the front of them.  Intuitive space is the creation of space without rules or guidelines.  Lines can create space, appearing to recede or advance.  Shapes can create space through overlapping.  Value can create space as well: usually the lighter something is, the closer it appears, and the darker it is, the further away it seems, although this can be reversed.  Texture can influence space: sharp, clear, and bold indicate closeness, and fuzzy, dull, and small textures usually suggest distance.  Color can also indicate space: analogous colors create limited space, while contrasting colors create a lot of space.  There is a way to create space called structured ambiguity, in which the shapes in the foreground and background seem to switch depending on what colors are around it.  For this reason, beginning artists are usually encouraged not to frame their work with a black mat.  Space is also crucial in three-dimensional work.  Sculptures could be flat, or they could have open voids.  They can be spaced apart enough that the viewer has to walk around or through them.  Instillations are works that the viewer has to walk through to experience, and they use space as part of the art.

I worked some more on my commissions and items for my online store.  I had a lot of fairly boring work to do, involving prepping the fabric.  However, I did get to do a bit of dyeing, all immersion this time.  I am doing some pole-wrapped bookmarks and some tie-dyed ones.  I also did a pole-wrap of a sample for the commission I am doing for my brother and his wife.  They want green and brown natural-looking placemats and napkins, but they wanted to see a sample first.  Fair enough: this gives me a chance to work out any kinks (like, how do I make brown?) before I start working on their actual project.  I also washed out a cloth I dyed yesterday, using pleating, but it currently looks so unimpressive that I didn't bother to take a photo.  I will use it to figure out how to create layers when the background color is dark.
