What three objects, and what three liquids, did you use for this picture?
It looks grainy to me like it was cropped or taken in low light, so I think more light or getting closer would help that. I also slightly disagree with the general consensus that you need a cleaner background. I think your depth of field is shallow enough that the whole background is blurred enough to not distract me.
I live how many layers there are here very interesting looking.
Besides using a neutral background, I think this image would be stronger if there was more “motion” involved- perhaps drop something dense like a marble to watch it break through both boundary layers?
Nice image. The background is a little fuzzy, maybe consider draping a white or black table cloth behind it so the focus can be placed on the fluid
I love the idea of demonstrating how certain objects go to certain fluid densities.
This reminds me of a triple-layered shot. I like the comparison of densities, and how the grape is breaking the barrier. I also like how there’s seemingly a tornado-like formation in the top-most layer just above the grape. Were any processing techniques applied?
I like how different densities and buoyant effects are shown in this image, but I would like the different layers and objects to be more clear.
I would take the extra effort to buy a new glass so the objects would be more visible
The blurred background go well with the picture when it comes to colors. I like how you used different objects along with the three fluids to demonstrate the density difference.
Loved the style it gave me “Stranger Things'” feels. I do not get the ping pong ball but great job.
I think the background is a little distracting, but I like that you can see the grape staying steady in the middle of the glass. That is very cool!
I love how the grape bends the surface, it really shows the boundary layer.
I actually really like your background. It has these pretty specs of light that mimic the circles. The colors go well together.
I like the red color and the contrast of it next to the yellow oil. I also like the tiny drops of syrup in the top layer.
I like the image, I would recommend a white background and using backlighting to illuminate the relationships between the liquids.
Did you drop the ping pong ball in the fluids or did you just have it sitting on top?
I like the background. It gives it a more realistic feel to the image
I wonder if this would’ve benefited from a lower ISO
As opposed to other pictures that show the density of fluids its really cool how you put different objects in to use a real life example and adds more meaning.
What kind of processing was used on the image?
Shows the effects of varying densities well, like you said, I think it would’ve been nice to have some sort of back drop to draw attention to the fluids.
How did you decide the different objects to put into the glass? How did you decide on the different colors of the objects? I enjoy the crispiness of the the fluid layers.
I think it would’ve been cool to see the objects as they were falling into the liquid and gone to rest somewhere inside the liquid mix. Maybe even a slow-motion video would’ve worked!
Its interesting to be able to see all of the layers of the fluids and how they interact.
The photo looks a little grainy in the back ground. It looks like you had plenty of light so lowering the ISO would still get a clear image without the “noise” from a high ISO.
As you mentioned, I wish the image was lighter. I also wish that there was a plain background instead of something blurred out.
I like the physics demonstration involving different densities shown here however, I agree that the background is slightly distracting.
