I was thinking about what to write in my next (meaning this one) blog post. I decided to post a few links on perspective that i've found useful. Perspective is, of course, drawing to a vanishing point or leading the eye. It's what gives a picture depth.
So, without further adieu here they are:
The first link deals with single point perspective. It's very basic.
The second link deals with 1, 2 and 3 point perspective. I found it very easy to follow and very useful.
The third link is an interactive site that has six different scenes for you to play around with.
The final link is very comprehensive. It deals not only with 1, 2 and 3 point perspective, but also eye level and horizons.
Hope they prove useful to you.
