The photos show the complexity of turbulence, which occurs in many different situations involving fluid flow. It's amazing that so much https://www.ncahcsp.org/buy-valium-online/ detail and beauty can be found in such a simple thing as pouring some water in a glass.

In physics, chaos theory is used to understand turbulence. Chaos theory is useful to understand complex phenomena that are especially sensitive to small differences in initial conditions. For example, each time that I poured the water was different, resulting in totally different patterns in the water. Besides turbulence in water, chaos theory is used for mathematically modeling other complex phenomena such as weather, the stock market, and heart arrhythmia.

The full moon last night was a supermoon, and was the closest to the earth that it's been since 1993. Because the orbit of the moon is an ellipse instead of a perfect circle, its distance to the earth varies from about 357,000 km (perigee) and 406,000 km (apogee)  each month. When the full moon occurs at the perigee, it's a supermoon or super perigee moon. The supermoon is about 12% larger than the average full moon because it's closer to the earth. Then next time the full moon https://sdarcwellness.com/tramadol-therapy/ will be this close will be November 14, 2016.

I took the opportunity to photograph the supermoon because it was a clear night (rare for Vancouver in March!) and an excellent opportunity to get as detailed an image of the moon as possible with my camera.

I used a 50-200 mm zoom lens at 200mm with a 1.4x teleconverter (to give an effective 283 mm) at f/5.6 and 1/100s s and ISO 100. I used a tripod with a remote and a 2 second timer to prevent camera shake. The image was cropped and sharpened using Adobe Lightroom 3.3.

Deep Space 31 by David Hull

I contacted David to find out more about his faux space light art.

Lloyd: How long have you been doing light painting?

David: I've been doing light art in one form or another since late 2006. I say light art, as when I hear "light painting", I think more of the kind of technique one typically sees in Flickr groups such as Light Painting - The Real Deal, and Light Junkies...stuff more along the lines of LAPP, where the camera is usually stationary and artists are moving around with various light sources in front of their cameras paitning in light streaks, etc. While I have done this sort of thing, it's a minority in my imagery.

Most of my early works were Camera Toss (Kinetic series), exploring the interaction of physics and light...a bit redundant, I know, wherein the light sources are usually stationary and the camera is thrown into the air to be acted on by physical processes such as momentum, rotation, gravity, etc. This is usually on a similar scale to the kind of light painting described above, but Waterworld is on a much smaller micro/macro scale.

Lloyd: What inspires you?

David: I'm a scientist (professional geologist) and am intrigued by physics in general, especially as it applies to terrestrial and space phenomena. I'm endlessly fascinated with the interaction of light, motion, and various reflective and refractive media, and the organic patterns that can result from their interactions. The exploration of these interactions forms the basis for my Kinetic and Waterworld image series. The Deep Space (Faux Space) images are an integration of many things I've learned through these other techniques.

I sort of have this childlike idea at the nucleus of my explorations that the images I produce using these techniques allow me to see behind or beyond the immediate dimensions. I'm also inspired by natural light phenomena (sunsets, clouds, shadows, nebula...that sort of thing), as well as abstract art and artists, historical and contemporary.

Lloyd: What advice do you have for anyone who would like to try this out?

David: Be comfortable with and have a good understanding of all the usual photography parameters. Take a look around at what is being done with light art as there are many different kinds of light art being practiced, but don't restrict yourself to mimicking the work of others. Be willing to experiment; to spend countless hours getting nowhere. Although there is certainly plenty of planning and reproducibility involved, there is also a degree of serendipity, and more often than not this kind of light art/light painting is an iterative approach to achieving a desired effect. One also needs to foster a certain sensitivity to the subtle changes in input parameters that can result in significant changes in the end result. Take lots of pictures and analyze them. Piece of cake!

I'd like to thank David for agreeing to share his photos and insights with me and hopefully this will inspire others to experiment with light art. As a scientist-turned-photographer myself, I'm certainly inspired by David's work!
