Fountain in the morning

I have returned to the same fountain for the last time to observe it in the morning light conditions. It is about 9:15 am. The first thing I notice is that it is at its greenest, but this time it looks less like the water is actually green (which was the case at the other times). The sky is bright blue right now, and there are no clouds to speak of. The sun is shining from behind me, poking through the trees. The shadows are distinct, but long. They are not as stark or sharp as they were last time, but they are definitely longer. Unlike the last time I observed the fountain, this time it is off. There is much less disturbance in the water, however, than when I observed it at night. There is only one source rippling from the drops of water slowly falling from the center edge of the pool by the second level of water. However, as I continue to observe a second source on the other side of the pool becomes apparent in the ripples of the water, but it is obscured from my vision due to my position and angle. This time the reflection is nearly a perfect image of the surroundings. There are only a few gentle waves here and there. The reflected greens of the tree are in almost perfect focus aside from some movement of the water's surface. The reflections of the surrounding stone lip looks almost white as though it were being hit directly with an intense light (but that can't be so, because the sun is coming from the opposite direction). It appears to be almost metallic and has a silver quality to it. There are moving lines on the stone rims. During my other observations these were dark shadow lines that moved quickly, but in this light they look more like light glows. They seem to be lines on the stone that are just a slightly brighter color than the stone, and they are moving at a much slower pace than they were yesterday. This is likely because they are a bounceback of the water surface light, and yesterday the fountain was on and therefore there was more rapid movement. As time passes, the ripples begin to move a little faster. Another distrubance develops on the surface towards the outer side of the pool. I am not sure why it has happened, but the result makes the reflection of the surroundings look much more distorted, as if it were painted in impressionistic, Monet style brush strokes. By the end of my observation time, the glow of the water's movement on the stone (the glow lines) seem to have vanished. I think that this is because the sun's angle is a bit more steep than it was a few minutes ago, so the light has evened out the glows a bit more than they were before.

Fountain in the Afternoon

So, my subject is the same as my previous post, only a different time. This time I'm observing it in broad daylight at about 1:30 in the afternoon. Like the other night, there is not a cloud in the sky. Unlike the other night, my light source is all natural (aka the sun). From where I observe the sun is at about 11 a clock from my head. The world is bathed in a sort of golden, sunny light. People are walking around and enjoying the afternoon, but I sit at a nearby bench and watch the water, occasionally walking up to the edge to change my perspective.

The first big difference I notice between the lower tier pool at night and during the day is the color of the water. I still suspect this has more to do with the water quality than the light necessarily, but instead of looking like a dark blue green, it looks like a fairly yellowy green lime color. It appears more saturated in this light. Another big difference is the fact that the fountain is actually on now, making for more hectic waves in the water. Because of this, the reflection of nearby objects in the water is difficult to make out because it keeps moving. There is an echo of the image, however, and you can see the basic shapes and colors of the nearby objects like the buildings and the trees. The colors that are reflected from the surrounding area are mainly the yellow greens of the trees (which are difficult to distinguish from the green of the water), the yellow/tanish reflection of a six pack building, and a few spots of bright blue from the sky. Again, because of the amount and rate of water spilling from the above level, the ripples and waves of the surface distort the reflections. This pace, however, make for a little flicker and sparkle effect the way the lamp posts did at night.

As time progresses, I begin to notice tiny bubbles develop on various spots of the water. These bubbles look like little sparkling spots, as the light of the sun hits them and travels through their thin, transparent shells at a quicker rate than it can travel through the water of the whole pool. They pop and form at random rates, and there are around 20 to 30 of these on the water's surface at a given time. I am not sure why they form, but the light reflects brightly in a yellow-white glow.

Finally, I take stock of the possible shadows. The shadows of nearby objects are dark, sharp, and distinct, stretching over the ground at about the size of their corresponding object. This obviously has little effect on the water, but I see a really slight glow emitting from the water's surface on the stones surrounding the fountain. These aren't exactly shadows, but little lines of violet-grey shimmer on the light-tan (nearly white) stone. Again, the sky quality has changed very little over time, so the pool appears nearly identical at the end of 15 minutes as it did when I first started my observation.

Fountain at Night

I begin my observation at around 8:30 or so at night of the fountain at the six pack. I had hoped to start earlier and get a little more of the light from sunset, but I am running a little later than I'd like and so the sky is already set a dark violet/indigo. It is a cloudless sky, and this near to the city makes for too much light pollution to see any stars. As it has been the case with my other evening observations, unnatural light is unavoidable, especially in such a high traffic area as campus. It's alright, though, because the nearby street lamps make for an interesting effect on the water.

I focus on the lowest of the three tiers of pools. The fountain is on at this time, but some water from the upper levels is still steadily dripping into the otherwise still pool. The water appears to be a very dark green, almost even black. I cannot tell if it has the green tint because of the quality of the water or because of all of the nearby trees. This is because the dark quality of the water makes it highly reflective. Since the water is mostly still, the image that is reflected on the surface is nearly identical to the actual object (whether it be a building, tree, or the rim of the pool). However, the detail of the image is a little fuzzy due to the really subtle movement of the water. It ripples slightly because of the incoming water from the above pool, but it also looks like otherwise isolated there are small ripples forming in areas of the pool that are far from the previously described waterfalls. Most notably, this gentle current in the water makes the reflection of the lamposts that line the sidewalk just beyond the pool flicker and seem to sparkle. The light from these looks yellow at the source, but in the green-tint of the water the light is rendered bluish. The spots of light grow and shrink with the flow of the water, making the reflection of reality a far more interesting picture. Another thing I notice is the way the reflection changes with my angle of perspective. The closer to the ground level, the less reflection is apparent. This is also true if I look at it from a perpendicular angle. As I get close to the end of my observation time, I take notice of the way the shadows on the stone around the fountain move. It is not very clear in my video, but to my eyes a very obvious set of sharp shadows (which look like really thin lines) seem to run up from where the stone meets the water through the topside of the stone. The lines move quickly, perhaps quicker than the apparent flow of the water. The shadows aren't very dark, as there isn't much light to make the contrast in the first place, but they are a sort of blue grey on the light tan of the stone. Since the sky conditions changed very little over my observation time, I can't say there is any big difference between the beginning and the end of my observation. Still, there was a lot to take in, so I may have missed a subtle change in conditions.

Jar of beans

I found myself in a more covered outdoor area of the coffee shop and noticed the tables had interesting little glass jars filled with white beans as centerpieces.  I thought they made for a good subject for my light journal.  Since I am in an outdoors but primarily covered area, it is sort of dim.  However, the light from the overcast sky diffuses inside through the open windows and makes for a soft light on everything.  In addition, although it is a mostly outside area and it is only mid afternoon, the bar-style neon signs are still on, emitting blues and reds around various areas of the room, including some areas of the glass jar.  The glass of the jar is completely clear.  It is shaped somewhat light a cube that rounds out into a cylindrical opening.  There is a ribbed  metallic covering over the lip of the jar, perhaps a modified version of what was originally the jar top.  The grooves of this catch the light and make shadows here and there.  As this part is metallic, it is not opaque and it has a shiny, smooth surface aside from the ridges of the grooves. The rim is also wrapped in a small, mostly opaque but slightly see-through, tattered ribbon.  The light hits this but does not reflect shiny the way the other materials do.  Inside of the jar are hundreds of little white beans.  I'm not actually sure what kinds of beans they are because I am pretty sure navy beans are bigger than that, but they looks like hundreds of tiny little taupe eggs.  They all have enough shadow and light around them that each is outlined and separate looking from one another.  In the shadows, some of the beans appear to be different variations of grey, lavender, light brown.  For the most part, the light hits the jar pretty directly, but towards the top where the mouth rounds out, the reflections distort and bend.  As it is an overcast day, I begin my observation without rain, and a mere minute or so in the rain begins to pour outside.  I am mostly covered, so the rain just drips along the walls and by the windows, making for soft shifting of shadows on the jar.  The jar is not really affected much, but when people pass by on the left, the red/orange and blue reflections from the neon and the white reflections of the overall light disappear.  A few minutes before my observation ends the rain properly lightens up.  Again, there is little obvious affect on the light on the jar.  By the end, little has changed with the light quality.  I suspect this is because there are so many clouds in the sky that the movement of the sun has little influence on the way the light is diffused across the sky

Cuppa Coffee

It is an overcast afternoon as I begin my observation here at the coffee shop.  With the threat of rain, I choose my location wisely and sit underneath a tin roof.  Unlike before, I've decided to place my subject before me, rather than look around for one.  Today my subject is my half full/empty coffee mug with a thin, wooden stirring stick.  It is blue, but has a red/purple quality that the camera does not seem keen to pick up.  I have placed it on a dark wood table, atop a dirty white napkin.  One of the first things I notice is how reflective the mug is.  The rim of the mug lips out slightly, and since the light is sort of diffused through the clouds and hitting in every direction, the outer most protrusions of the rim have a little specular reflection on either side of the cup.  the handle of the mug also has a little reflection on the interior of its curvature inside of the shadow.  The best example of this mug's reflectivity, however, is the body of the cup itself.  Where the bottom meets the napkin, there is an obvious mirror reflection of this napkin on the cup's face.  I move my hand around to see just how much reflects into the cup's body and at a short distance my hand also reflects into the cup. Although it is close to noon, there are no apparent shadows because of how soft the light is.  Only about a minute into my observation, the threat of rain becomes true.  For a couple of minutes we are hit by a hard rain from a side angle.  I take out my colorful umbrella to protect my observation area (and myself!) from getting drenched.  I keep my umbrella covering us for the remainder of my observation period, but for the last 10 minutes the rain is more gentle.  The red from my umbrella does not make for too much of a color change on the mug, but it does keep the light extra soft.  Although the umbrella is opaque in appearance, the surrounding light passes through and diffuses without casting any real shadow.  By the end of my observation, little has changed from the beginning outside of the rain.  However, the overall softness of the light through the clouds makes the changes almost entirely unapparent.

Silhouetted Tree

As I took an evening walk around the perimeter of my apartment complex, I came across a really nice image of a tree branch full of leaves silhouetted against the sky.  I really liked the dark quality of the picture, so I decide to use it as another light observation.  As it was the last time I tried to find a subject in natural light this late in the day, manmade lamps are nearly unavoidable.  However, the tree I am looking at does not have very much manmade light hitting it directly.  In fact, this side of the street has no lamps, making for a relatively dark area compared to the light on the other side, where lamps are distributed about every 20 feet.  Tonight, the sky is pretty cloudy, but bluish white light of the moon pokes through every so often.  The sky looks like a desaturated shade of purple or lavender, with the smokey clouds influencing the way it appears.  From where I stand the leaves of the branch I focus on appear almost black.  The little leaves on the left side of the branch are especially dark and look blackest, where as the leaves on the bottom right region look to be brown or even yellow.  At first I think this is an indication of the fall season and that the leaves are dying, but upon closer investigation they are actually quite healthy leaves that probably look green in daylight.  I can tell, however, that the leaves look brown/yellow as a result of the reflection bouncing back up from the grey/dirty street (probably an area of road in a pool of light from the lamps across the street).  There is no obvious cast shadow that I can see from these leaves specifically, but if I turn my head and look to the left behind me I can see the the shadows are long, dark, and sourced at the root of the tree.  The shadow from the leaves is probably somewhere far off behind me, give or take 20 feet.  I continue to watch the leaves as they move gently in the breeze.  Over time the moonlight's influence becomes more intense because the clouds move around, and the leaves on the left side pop out a bit more than they did before.  Also over time, the light on the leaves changes because of cars driving past in either direction, or the cars driving through the nearby intersection.  The lights from these are almost always blue-white, and the intensities from them vary as they move.  For example, the cars driving at the intersections only subtly cast a light on the edges of the leaves, making the individual leaves more apparent.  When cars pass on the street where the tree is, the leaves are nearly entirely illuminated by artificial light, making their color a washed out version of their green pigment.  By the end of my observation little has changed.

 

I had a little trouble capturing what I saw with my camera this time, primarily for lack of light.  I tried several settings and video settings, but in the end I think the only one to closely capture what I saw was the "foliage" setting of my camera (as it realized to open the aperture to f2.8 and used no flash).

Metal Chair

Moving away from nature after doing 4 entries, I decided to look at something manmade. My subject today is a metallic chair, much like the one I sat on while observing. It is about 5 pm, and I am sitting outside of Which Wich under the shade of the concrete overhead. The way the chair I am observing is situated, however, the sunlight hits it directly from an angle on it's left (my right) side. The chair is primarily in the shade except for the one spot of light that spans less than half of the back of the chair in height and about 2 inches in width. Here, the light reflects off the chair in a slight yellow and grey. The material of the chair, as implied by the entry, is metallic and grey. There is also some light hitting the base of the seat and reflecting back, and a subtle reflection of the light bouncing from the brick on the ground. The legs are made of a cylindric pipes on either side that were bent into arches (for arm rests) and connected to the rounded seat outlined by a similar pipe as the chair legs. It was obviously painted metallic, but it wasn't overly shiny like iron or aluminum. The actual seat of the chair also had a mesh texture made up of hundreds of tiny eyelets. From my perspective these eyelets appeared to shift in size where the curves of the chair rounded and warped. Although the chair was in the shade, each eyelet had a tiny reflective spot of specular light at the bottom. The color of the chair in these shaded areas was a cooler grey, on the blue side. Because it was in the shade, there was no stark shadow of the meshes but there was a slight indication of the leg cast shadows that diffused immediately into the shade of the area. As time passes, the spot of light disappears for a couple of minutes, but returns by the end of my observation (however, it has shifted slightly towards the direction of the base of the seat).

Here is the video I took. Again, the camera is overwhelmed by the light, and I need to figure out a way to get my camera to handle this!
