Great idea to excite the fluid using a woofer. And good job experimenting with the viscosity of the fluid (by adding milk to latex paint) until it did exactly what you wanted it to do. I really like the use of lighting and shadows to show the suspended droplets, it dramatizes the reaction of the woofer vibrating the fluid. Good use of soft light red dye on about half of the image, and fluorescent greens and blues on the other half, not fully mixed in the milk and paint. It was probably pretty tough capturing this above-angle image in great focus, but you did it well and created your own perspective of the project. Nice job!
Cool idea for a flow vis photo. I like that this top view gives you some idea of a pattern or structure to the waves in the paint. The position of one paint droplet in the center of a wave trough suggests at least a temporary standing wave pattern to me.
Great color choices. I love the details and contrast. The floating drop is really spectacular, as well as the shadows.
This is an absolute joy to look at. The way the waves move across the fluid screen almost look like an image taken straight out of a Dr. Seuss story novel. With everything that is occurring, I feel as though it’s so in-depth that I can almost touch it. I practically want to touch it. The artistic merit that I see is how the colors curl into one another. Adding curvature to fluids or capturing their movement as its caught in some sort of flow adds a lot of merit and excites the image; there is nothing more boring than colored fluids which are not doing anything in their containers. The small bead of fluid caught midair is a nice touch; you were lucky to capture that. Although I wish it may have been better if it was shot from a diagonal angle instead of top-view, the top-down view does not detract from it any way. I look forward to seeing similar images like this in the future.
Unique way of shooting from the top view. It makes the viewer really have to think about what is going on in the image and what the structures look like.
I like how the mixing can be visualized so easily in this image. The angle this shot was taken from makes me think that this is almost a topological map. Nice colors and focus!
I appreciate how the opaque reds on the left contrast the bright neon, greens and blues on the right. It adds a gradient of contrast within the fluid effect being illustrated. The changing lengths of the shadows may offer implicit hints of the height of each node.
Cool image ! The contrast is cool but I’m not so sure about the color choices. I love the lighting and focus.
Really great focus and I love the marble pattern with the color gradient that you chose. It looks almost like a birds eye view of a landscape.
Good colors used. Like that it is more of a top view. I really like that you can see the divots and crests. The single droplet is very cool, attracts the eye to it.
Colors and swirls are gorgeous. Love the symmetry in the photo created by all the craters. The droplets are really cool, really draw your eyes to them. Photo is crisp and clear.
I really like the shadows, the swirls and colors are mesmerizing & you’re correct the one drop draws the eye.
Art: Love the the clash of colors between the right and the left
Flow: I really like the top view of flow creating a crater like effect in the paint
Technique: Great focus
Interesting formation of the fluid. The color choice is not normal but adds a unique effect. Great contrast.
Art: The use of dramatic colors is very well done.
Flow: The flow is quickly understandable and recognized.
Photographic technique: The focus on the fluid and the droplets are fantastic.
I really enjoy the perspective on this image. It fits well because of the great capture of shadows. The one droplet definitely captures your eye right away. I like the overall colors even though there is not much action in the green area.
1. The image is artistically excellent. The colors are very vibrant.
2. The fluid physics are well shown.
3. The photographic technique is very good.
Awesome colors and mixing. Droplets are really eye catching and make this image pop. The shadows also give this image some depth.
Brilliant colors, with excellent contrast. The mixing is very nice. The shadows add a nice effect, and I appreciate the single drop in the image, however, maybe center the image around the single drop?
Very interesting angle to view this vibrational phenomenon! Having the contrast between the colors displays the fluid motion very well.
Wow! The lighting of this photo adds a really nice effect, you can really see the textures of the liquid with the shadows, the bright colors are really nice, the few drop peaks on the left really draw in the eye. Interesting perspective of the fluid phenomenon.
the perspective of this photo is excellent. i really like the mixing of the colors in the photo caused by the motion. the drip silhouetted by the depression below is very cool. really nice work
Very interesting and complex composition. The focus is great. The contrast created by the shadows is really great. The popping color is really great.
This is a great photo! at first glance it looks like a topography map and not fluid on a speaker. I like the different view on this photo.
– Great image.
– I really like the dark spots in the food dye and the blue swirls.
– The photo is well resolved.
I really like how your team had such different photos documenting the whole phenomenon. The overhead view reminds me of satellite images of weather, especially with that nice spiral of paint on the right side. I really like the mixing of colors, with the left half pink and the green right half giving some color symmetry.
Great angle. Allows for good comparison of your other teammate images. Great color and detail as well.
