Above is an image I took when pouring olive oil into a glass of vegetable oil. As you can see, the different oils do not mix and can be individually seen in the photo.

I am enthralled by the striped streams in the fluid – and all the shades of yellow.
The lighting is perfect! You did a great job with the framing as well! I’m interested to see what different colors would of showed
Nice focus and lighting! Also like how there’s so many shades of yellow all blending together
Love the subtlety. Really neat interaction. Lighting and focus is good too. Maybe the strands could have been accentuated more but overall nice capture
Art: Beautiful and subtle color change. The streaks are especially alluring.
Flow: Very neat! Cool bubble capture!
Technique: Post-processing might bring out the streaks more. Beautiful though!
The streaks in the top left look awesome.

Great lighting. How long did you allow the mixture to settle? It’s very subtle and the streaks almost look like hair.
This is a really cool photo! The physics of the flow are clearly visible and the image itself has great clarity. I really like the swirls of color in the top left
Great choice of colors, I would personally frame the subject more towards the center, and increase the contrast so that the dye and the oil are easier to tell apart. The image does make the fluid look more viscous than it is in real life.
-The color is very intriguing.
-The lighting is perfect.
-Interesting idea
I can see how two different oils mix together. Beautiful color!
The color of the oil pops with the white background. The bubbles in the flow really make the image, I like the overall composition of the flow.
The effect here is really interesting, but subtle. I would like to see more contrast and focus on the lines mixing on the left. Otherwise I like the lighting and off-centrr composition.
The lighting works great in this image. The bubbles draw the attention around the glass.
This is pretty beautiful and the air bubbles add somewhat of a cozy feeling to this picture, was that intentional? Maybe some more cropping to capture more of the essence of the picture and using different colors because it’s hard to differentiate the colors of the fluids.
The mixing is very subtle, however, it is a lot of fun
I like the subtle flow the occurs between the two oils. Everything is focused, and the framing is well done. The contrast between the two oils is a little hard to see.
Nice idea and looks pretty good. I think the lighting is a bit too bright, especially in the left corner. You may want to turn down the flash or lighting on the left side.
The picture looks cool especially with the bubbles in the oil. The color is cool and the background is a nice bright white which makes the image pop.
I like the concept a lot, at first I only noticed the air bubbles however. The bubbles are very interesting, maybe a future image could focus on the bubbles while having more contrast. Overall great work.
I like how you can visualize the movement of the flow in the still photo. Well done on focus and framing composition.
Mixing two different oils is a cool idea. I like the air bubbles within the mixture, it adds a nice texture. The colors are nice as well. The left side is a bit blown out (too bright) maybe consider cropping or masking that part to bring the highlights down.
Interesting experiment, however the flow isn’t super clear. I like the light contrast on the background.
I find myself focusing more on the air bubbles suspended in the oil. I actually didn’t even notice the two different oils mixing at first. The differing materials is hard to see.
I like the closeness of the image with respect to the glass. I would like to see this liquid a little more centered in the frame. This image might benefit from a little softer lighting so that we can see the two liquids more distinctly. A nice image nonetheless
I really like the flow in this image. The colors are also really nice. The background is nice and simple too.
Maybe crop out the bottom on the glass?
The lighting used really captures the air bubbles trapped inside. It’s difficult to see the oils mixing but the bubbles add great effect for these fluids.
Art
It’s super subtle. Maybe you could play with the colors?
Flow
The turbulent mixing effect you went after is pretty cool. I see it now.
Photographic Technique
The picture focuses the viewer on the bubbles, which maybe distracts a little from the mixing fluids.
Cool color, and good use of fluid flow. I might change the setting of the picture, the background seems overexposed. I like the faint swirls in the fluid.
The movement of the flow is subtle yet are aesthetically pleasing. The bubbles and said movement work in harmony to make a compelling image.
I think because of the similarity of the colors of the two oils, the bubbles sort of take over, and I like the way the bubbles look galactic.
The mixing of the two oils does create an interesting wave effect that looks like atmospheric patterns almost. I would consider playing with contrast in this image to bring that out
Very nice lighting, the image is in focus! Would be better to see more flow in the image. Well done overall.
Very beautiful picture, interesting idea. Very colorful and good focus. Good framing.
Nice picture. The focusing is cool as well.
I like the subtle streaky flow in the background. Interesting concept.
It took me a while to notice the two oils mixing, it’s a great contrast and a very subtle detail, I think that makes it very interesting. The flow is shown well here. The colors look nice and the focus is also great
I like the subtlety of the flow in this image, you see more as you look at it longer. The framing is great and conveys everything very nicely
I think you could have maybe dyed the olive oil somehow or have chosen a different fluid so the viewer could easily distinguish the two from each other and observe the phenomenon occurring. Otherwise, the image is in focus and I can make out the fluid flow in the image.
