Much like in the building of a truly passive solar house, taking a photo often requires some understanding of the elements which are involved in the process. Many people pick up a camera and begin shooting away at whatever they think appears to be a moment suspended in time worthy of a lifetime of memorialization, however, proper understanding of photography can produce a photo well beyond what was originally intended to be captured. If light is understood when working with photography; understanding overhangs, and how to minimize or maximize light, how light will play off of or interact with the subject, impressive things can be done with a simple camera.
This really makes you think about energetic light is. By controlling the amount of light entering a building one can drastically change the temperature of said building. Sunlight does this over an incredibly large area which is extremely impressive to think about.
I also agree with what Natasha was saying: It is important to understand light when taking pictures. Since photography is basically capturing light it makes sense that you need to understand light in order to do this well. A photographer not understanding light would be like a painter who was confused by paint.
Looking at a "passive" solar home, it is hard to imagine who gave it that name. The process involved is far from passive! It is a multi-step process to get from point A to point B. The same can be said for taking photos. From the point of taking the photo to actually printing it out, there are many steps that have to be considered. All of the processing, developing, and enlarging takes time.
I know we all like to think that light is full of energy, but it really is not. First off, light is a form of energy; therefore, light itself cannot contain energy. Secondly, and more importantly, photons carry very little energy on average. A red photon has around two electron volts of energy, while the energy equivalent of the mass of a single hydrogen atom scales to be on the order of 10^9 more energy.
I think this article was interesting; the author clearly against the idea that you can assign rules to create a "true passive solar house". I do agree that some types of rules are somewhat necessary in terms of government regulation- perhaps providing tax relief and rebates to owners of passive solar houses- and in real estate listings as well, however theoretically this is wrong. Assigning a list of regulations such as window angles etc cannot be done because there really is no right or wrong way to create a house with passive solar energy as long as it truly does utilize it.

ReplyDeletelight IS energy.
Deleteeverything is energy.
