Great job thinking on your feet and putting alcohol through highlighters to get a fluorescent dye, then capturing it in a “flavor blaster” syringe. I really like the time step effect of this image in particular. Good idea to combine multiple images together to show what’s happening over time without a video.
I think you made a wise choice to show the progression of the jet mixing to overcome the issues you had with image quality. With the level of lighting you were dealing with getting a low noise, well resolved image would be really hard. The mixing surface of the jet in the 2nd and 3rd frames reveals that cool textured interface you get from the range of scales of turbulent eddies.
This is a great idea! You’re totally right; the motion blur is not noticeable with the multiple images. I can almost see the flow moving before me. The shadows are really great and enhance the effect of the injected liquid.
1. Very interesting cool image.
2. The fluid physics are well shown.
3. The photographic technique is very well done.
This a good approach when trying to salvage the image’s resolution that you were not pleased with. I also like the discrete point sources on the bottom of the glass that appear to be the reflections of the two bulbs on the bottom surface.
I really like your decision to show the progression of the static photo. It is a very interesting process on how you were able to obtain the dye from highlighters. Great work!
Dan this is cool!! I love that you put all the images into one! So cool and the color is great.
Awesome process for extracting the fluorescent dye. I like the progression of the shot, and even thought the shot was at a slow shutter speed, I think the shots still show the progression great. The glass on the left disappears well into the background, but all shots weren’t edited the same, so the one on the right is more apparent and you cans see the image separation. If you use a batch processor to apply the same setting to all 6 images it could be better!
Really cool idea to portray the motion through multiple photos. The quality is great. The jet created such a cool puff, almost reminds me of a cloud.
I like the individual photos, put together to show the time. I would remove the last image, just because there is not much turbulent flow and the shade/color is slightly different from the other image. Its also interesting as more liquid is adding you can start to see the outline of the glass through reflection/boundaries.
I would want to see each of the photos individually. Off hand i would think that the second one form the left could be very interesting just by itself.
This is an original and very interesting idea for a fluid flow phenomena. The colors are amazing. Have you considered maybe editing out the purple reflections on the bottom of the glass and bringing out a greater contrast in the photo?
I think this is a very interesting experiment, I like that you were able to make something from some images you weren’t to happy about. I like the greens and the contrasts create a mysterious picture.
Good focus, I like how you can see the progression of the drop. Nice extraction of the fluorescein. The contrasts between the shadowing and the lighting is nice. Nice coloring.
I like the sequence of shots in the shot glass, they do a great job of illustrating the mixture process. The fluorescence of the image makes it look very cool. I actually really like the purple aftereffect in the bottom of the glasses, it gives a nice sense of contrast. I think if you used more ink and a bigger surface of water you could get a great standalone shot from either the second or the third shot.
Great work to show the progression of the flow injection. nice work capturing the image with such a low light situation. Capturing the detail within the flow as it progresses is nicely done
I love the display of time in this image! The fluid flow is very well displayed. The motion blur doesn’t take away from the image at all. Very well done.
Cool to see the progression of the dye as it diffuses within the water. The picture is of great quality and and the middle images are kind of like a shrub or push.
Interesting to see the flow development over multiple frames. However you might want to consider either keeping or removing the last image, as it is sort’ve cut out. The shape of the flow is excellent. Also you might want to crop out the purple on the bottom and the injector on top.
Great contrast and great flow visualization. I love the glow of the Fluorescein from the black light. Very aesthetically pleasing.
Very cool succession of images. Really helps to visualize the motion of the dye filling up the container. Would be really cool in slow motion!
Art: The color contrast between the background and the dye is very nice.
Flow: The flow is quickly understandable and recognized.
Photographic technique: The focus on the individual plums are great.
Art: Really awesome flourescent colors
Flow: The various stages really makes the flow easy to understand
Technique: Great contrast range
I like the use of only green for the flow. No distracting elements. Good example of turbulent flow.
– Great photo, this reminds me of something from a sort of sci-fi movie.
– I like the addition of the blue lighting at the bottom and the nice cloud progression.
