WR: Understanding Exposure *Read p. 72-91 + Take 1 & Study 1 Picture*

Had a busy weekend of picture taking - hooray!  If we're lucky, I'll get some of the pictures on here.

I realize as I cover these book chapters, it would be more helpful to actually summarize them, but time just does not allow.  So, I'll assume that you can read them yourself and keep on saying what I liked about the chapter.

This week's reading was about shutter speed.  Here were the things that I found really helpful this week:

-You need a shutter speed of at least 1/500 to 1/1000 to stop motion (p. 76).  I've attempted on a few occasions to stop motion, only to fail miserably.  Now I know what to aim for.

-Use slower shutter speeds when panning - 1/60 to 1/8.  Huh.  I'm still not sure how to do this and not get blur caused from the movement of my hand (ie, up and down /crooked blur).  Something to work on later.

-1/2 sec gives you the cotton effect with flowing water.

I suppose I already knew the basics of shutter speed, so what I took from this reading were numbers that will give me a basis when I'm out shooting.  It gives me an idea of what shutter speed to look for.

The picture this week:


This was a very good exercise in the use of light for me.  This is a wine glass with water in it and a candle behind the glass.  Moving the candle closer or farther from the glass completely changed the shape of the light around the glass.  Very interesting.

This picture kept looking slightly crooked and I couldn't figure out why.  I think the glass is actually now straight (after a little post-rotating), but the water is still crooked!  No wonder it looks funny.  I may attempt this shot again at some point now that I have a better idea of what results.
