Bonbai~

Bonbai? What is that you ask? Well it is a bonsai ume(plum) tree and I got one!

I went to Nagahama to blow glass and also happened upon a bonsai exhibit. Now being American it is always interesting to see things that are, well, older than my country. I know that sounds weird but hang on a moment I shall explain. Japan, China and some parts of India have some of the longest, static, by static I mean continuous culture/tradition/history, which I find fascinating. Of course some things have changed but as a whole compared to the rest of the world there hasn’t been and huge revolutions to the heart of the culture and tradition. So when I saw these little trees that were 400 and some years old it made me stop and think. This art, this piece of culture has survived so much and has been passed down successfully that it makes one want to be part of it, to be a small piece in the bigger picture. So, I bought one and will attempt to not kill it!

 

Its actually quite a bit of work once every 3 years or 5 years. The repotting process is daunting but I will attempt it this December. In the meantime I get to enjoy the lovely blossoms this year and will have to prune and water only until December. It also makes a great subject for photography~ So there shall be many more photo experiments to come that include this new little member of my family.

My first experiment was with time lapse. I know, I don’t start small. So for my first ever time lapse I would have to consider it a success! It was actually much easier to do than I assumed it would be. As you know, I have a Canon 7D and thats pretty much all I really needed. I didnt have to purchase any special software. I used the EOS Utility and iMovie, as I have a Mac but I am pretty sure you could do it in just about any regular movie editor.

Using the timer in EOS utility you just have to make sure your live view is off. Set your camera up on a steady tripod and fix the focus, DON’T use autofocus as it may search each time for a new focus point or be unable to find it. I ran my camera in Manual but you could also do this in AV, TV, P or B. Depending on the length of time you need between your shots or the length of your shots I have read you may have to have it in B, given that I was throwing mine together before work and have yet to attempt another one I am not sure if this is true or not. I set mine to take a photo every 30 seconds and just let it go. I had originally had it set to take 500 photos but it only took 372 as the light and my camera both died. I highly recommend starting with a fully charged battery! Mine was down to the last little bar when I started, fail on my part.

I stuck around for the first ten or so actuations and then left for work. Came home and threw all of the photos into one folder and then imported them into iMovie. Set the display time to 0.1 seconds and fixed the crop so I didn’t have that goofy, ahem, I mean supposed cinematic effect. All in all 372 photos became about 50 seconds of movie. So not overly long but considering I didn’t do a lot of work on my own not bad. Now I did take all of these photos in RAW so I could go in and batch edit or fix a few if it seemed necessary, however, as this was my first attempt I was more worried about it actually working rather than the quality of the images. Bad, bad, bad Anne! I know, but now that I have this part down on my next one I can work more with the quality of the images. My biggest worry was to do a lot of intensive work and then have it fail somewhere along the way. Now that i know the first few steps I feel more comfortable putting more work into the next one. I would like to try a night time lapse but we will see how it goes. I would need to get out of the city and into the countryside to actually be able to see the night sky. But when i get this down I have a new reason to climb Mt. Fuji this year, because there is this great little spot near the top that I think would look great in a time lapse with the stars.

Camera History: Early Fixed Images

It’s another installment of Camera History!  Last time, we covered the precursor of the modern camera, camera obscura.  Today we’ll delve into the very beginnings of photography with the earliest cameras and experiments in capturing an image without having to trace it.

The first partially successful photograph was taken in 1816 by one Nicéphore Niépce.  When I say “partially successful,” I mean that the photograph was not permanent and eventually darkened completely.  Niépce used a small camera of his own design and a piece of paper coated with silver chloride, which darkened where it was exposed to light.  He didn’t know how to remove the unused silver chloride, which is why it was not permanent.

Before the photographic process was perfected, there was no way to truly preserve the images.  After some experimentation, in 1826 Niépce used a sliding wooden box camera (made by Charles & Vincent Chavalier in Paris, France) and bitumen to create a permanent photograph that still exists today.  It’s not a perfectly preserved image, but it was a huge step forward.

I want to get in to the chemical details of both silver chloride and bitumen, but first I just want to give a sort of shout out to Johann Zahn.  Zahn envisioned the first camera that was small and portable enough to be used for practical photography in 1685.  It wasn’t until about 150 years later that his vision would be possible, but gotta give credit where credit is due!

Alright, time for some science mixed in with this history!

First up is Silver Chloride (AgCl).  It’s known for it’s low solubility in water.  How it works in photography is that when silver chloride is exposed to light or heat, it changes into silver and chloride.  The silver appears as a grey or purple coloration where as the chloride dissipates into the air.  It is also used as/in:

  • an infra-red transmissive optical component that can be hot-pressed into window and lens shapes
  • an antidote for mercury poisoning
  • a way to create yellow, amber, and brown shades in stained glass manufacturing
  • bandages and wound healing products

Then we have bitumen, aka asphalt (that surprised me, too!).  It’s used in the oldest surviving photograph.  It can still be used for photography today, but it’s a long process to get any outcome.  First, you have to thinly coat a pewter plate with bitumen.  It takes many, many hours of exposure to light to create a picture.  Exposure to light hardens the bitumen and makes it insoluble.  When the final picture is rinsed with a solvent, only the sufficiently light-struck areas remain.  However, ultimately, using bitumen in photography is extremely impractical.

And that wraps up our lesson for today!

I’d like to take a moment to apologize for getting off schedule.  I was at a wedding over the weekend, and Anne was on a photojournalist gig.  She’ll be posting on Sunday and then starting on that Sunday, posting is going to get more intensive!  We’re going to attempt to post every day of the week!  So stick with us through September to see all the cool things we come up with!

Get out there and shoot!

Camera History: Camera Obscura

If you’ve come to this post looking for Camera Obscura the band, you’re now stuck reading the whole thing to get to the video at the bottom.  I’m using the honor system here, so no cheating!

Alright, my dear readers, it’s time for a history lesson.  Today I will be writing about the history of the camera.  Well, part of the history of the camera.  There’s a lot more to the invention of the camera than I thought, and a lot more steps from that to the DSLRs we use today that I think are important to cover more in depth.  Especially since the history of the camera goes back farther than the history of photography.

To get to the invention of the camera, we have to start with it’s predecessor, the camera obscura.  This device dates back to ancient Greece and ancient China and was a tool that helped mankind learn about light and vision.  The term “camera obscura” is Latin and means a darkened chamber (camera = vaulted chamber/room, obscura = dark).  German astronomer Johannes Kepler – you might know him from Kepler’s Laws of Planetary Motion, if you paid attention in science class – coined the term in 1604.  The basic purpose of a camera obscura is to project an image of it’s surroundings on a screen or wall and is used for entertainment and drawing/painting.

A basic description for this type of device was first mentioned by Chinese philosopher Mozi (470 BC – 391 BC).  He described what we now call a pinhole camera-type device, referring to it as a “collecting plate” and a “locked treasure room.”

Alhazen, an Arabic scientist and astronomer, gave the first clear description of a camera obscura as well as an analysis of the device and what it does.  He was the first to demonstrate that what was being projected is an image of everything on the other side of the hole, instead of just light, as previously used.  He did this by successfully projecting an entire image from outdoors onto a screen indoors.

In the 9th century, Chinese scientist Shen Kuo attributed the fact that the image is inverted to it being projected through a small hole.  Earlier beliefs held that the reason for the image being inverted was caused by other things.  For example, one earlier Chinese philosopher wrote that the inversion of the image was caused by the camera obscura being set up next to the sea and the image being of the sea.

While the camera obscura had mainly been used for entertainment as well as studying various aspects of light, in the 13th century Englishman Roger Bacon suggested that the device could be used to safely observe solar eclipses.  It’s use as a drawing aide wasn’t widely seen until the early 15th century.

Giambattista della Porta ‘perfected’ the camera obscura by adding a convex lens to the hole to make the projected image both brighter and more in focus.  He used this as an easy-to-understand example of how the human eye works.

Early models of the camera obscura were quite large, needing an entire darkened room or tent to function correctly.  But as advances in science were made, the camera obscura became more and more easily portable around the 18th century.

The camera obscura, while not an actual camera, is still used today.  It’s main purpose continues to be entertainment, education, and is still used as an artistic aide.  Basic ones are fairly easy to put together, as seen in the picture below, but more complex configurations exist as well.  You can see a neat visual of the timeline of the camera obscura here.
