It looks very grungy like that’s a place I don’t want to be. Makes me think of moldy food in a refrigerator. In that case, it communicates the aesthetic well and is a very detailed image focused on the subject.
Great contrast of black, white, and green colors that really make the image pop. Good camera focus and image editing to ensure an appealing and crisp picture. Interesting experiment and overall good image.
Very nice, artistically it has great colors and focus on the subject. The flow also looks dynamic and is intriguing, I also like the technique of the photo. You have cropped the image well and it is focused really well, the picture is high quality.
The colors are beautiful! everything is in great focus
Great focus and color spectrum! The bubbles make the image feel as if we’re underwater in a lost world; reminded me of Star Wars or Avatar.
Really good focus. I like the way it looks sort of grainy. I’m curious what it would look like zoomed in more.
The drops of red makes the contrast of the colors better. But maybe some more drops of red would help. Very good focus the intent of this was definitely realized.
art: Nice choice in post processing. It reminds me of a Netflix intro.
Flow: Nice flow! lots of drama and interesting viscous effects.
technique: Well done. You can darken things with a masked exposure filter.
The physics of this setup is really interesting. The bluish shape in the background is omninous and is a nice contrast from the crisp focus of the image.
Nice Image, really like the contrast of the food dye. I would try a different dye just to see what would look better.
The focus is really good. The reflections on the side of the glass really give the image depth. Cool multitude of colors.
Very interesting picture, very colorful. Good focus, exposure and timing. Flow is understandable.
I really like the colors here! The right side of the glass is a little distracting, but the phenomenon is pretty sweet!
Is the focus on the edge of the glass or the center of the fluid? Really like the colors.
The focus is pretty nice in the image. I would like to see a little more color i this image. It’s a lot of clear liquid and dark droplets.
Great image, I love the focus and framing. The small amount of red really adds to the aesthetic
Nice composition. The inkiness of the die is strong and really creates a unique aesthetic. Good focus and lighting too.
Good image, the idea is very creative, I like the red color, highlights the image. Good focus, the blue is a little too dark, maybe try some editing on it.
I like how speculating and fragmented the droplets are. It has nice depth, like a star field, and the focus and cropping are nice. Overall an interesting aesthetic captured well.
The image looks like holding a lot of colors in the wine glass. I like the bright background so colors are more visible.
The dark blobs in the front really stand out against the eggshell/light blue background. I feel some of the motion.
The picture looks cool with the different colors in the glass. The flow is cool how some of the liquid gets stuck to the side of the glass. The focus is good.
Good choice of adding red to change the contrast. The edges of the glass are a bit distracting, but I think cropping them out would be too much.
very strong and vibrant juxtaposition of colors and great focus. Maybe adjust the brightness through the background.
The lighting in this image is great. The flecks of red color throughout the image are great. The focus in this image is great as well. Interesting that the food coloring stuck to the sides.
Art
Real cool!
Flow
The drop with the circle on its top is nice
Photographic Technique:
The focus is really good. I like the narrow depth of field, it helps the aesthetic.
Great job using the tablet to create an internally driven flow. I really like your focus and lighting choice.
Very strong bold colors. The darkness gives it mystery where as the use of different lighting and reflections help shape the image.
The image is well focused, and I like how the droplets become more out of focus the further into the glass they are. Good contrast, and the droplet formation is interesting.
The colors in this glass are vivid and grungy and your usage of depth of field really puts the user’s focus at the right place.
Beautiful focus, and I like how this image is different than the other lava lamp experiments. Nice background, lighting and focus. Great job.
Cool picture with food dye and oil. Little more bright color would be kind of better. I love the focus and lighting.
Nice job Casey, the colors work really well togeather. I also like how you zoomed in onto the glass. The red specks are a nice touch.
I like how the food coloring in the front is in focus but the colors on the back side are not in focus. The difference is aesthetically pleasing
The flow physics are very visible and the image itself is very clear. There is great detail in the little dots throughout the mostly black bubbles. It is pleasing to look at.
I love the greens and blues of this. The viscous effects on the side of the glass is really cool. I love the droplets and bubbles too.
Maybe crop it a bit more or zoom in?
I really enjoy how close you zoomed into this picture. It allowed the focus to really be on the fluid flow, and you aren’t distracted from anything else.
I like all the different colors, It looks ghostly. My only suggestion is getting a better focus, maybe with the edges in focus.
Very cool photo. I like the really dark colors paired with the greens and blues in the back. I like the cropping in the photo as well, it really focuses on the fluid flow.
Contrast is nice, and provides a strong aesthetic.
I really like how the colors came out actually, and the photo was well lit and well taken. Very strong compositionally.
Very nice colors in this picture. The idea is cool and the zooming looks great!
Really like the color and the contrast between the food dye and the oil.
Aesthetically it is an unsettling image, which is a nice change of pace from the other images. The flow is demonstrated nicely
I thought it was very creative of you to include an alka seltzer tablet to initiate some sort of turbulence within the water and create a fluid motion. Overall, great image and everything is in focus.
