If you are looking to expand your depth of field (which is an issue that I struggled with in my photos) and keep the images crisp, you may want to think about adding a few more light sources. This would help you close the aperture a little bit (increase depth of field / reduce your focusing issues)
The smoke rings may be a bit overexposed, so that may be worth adjusting. However, I do like the strong white/black contrast in the lower black band of the image, below the wood-grain texture. I think the image would be stronger overall if the background was that same solid black.
I thought this was a very cool example of laminar flow, I think you did a good job of setting up the image and making the rings the subject of the image.
I like how you’ve captured two rings instead of just the one. It gives us a sense of how the rings were moving. What do you think of the focus in the top right corner? I like how we can see some vortex details on the leftmost side of the left ring.
I like how you were able to capture multiple phases of the smoke rings, maybe next time try to enhance the focus on the rings so they are captured more clearly.
I love how we can see the procession of different smoke rings! That’s a really cool effect. Did you dampen the light in your lighting set-up in order to photograph the smoke? Also why did you choose the background with the wood grain?
I really enjoyed how you can see the full processes of the smoke ring and how you can it see how it flows from the middle until it “dissolves” back into the air. I definitely recommend using a faster shutter speed (like at least 1/100 of a second and a wider aperture (above F 8.0) to be able to better focus on the smoke rings. This will reduce the light sensitivity of your camera but you can increase your iso and add more lighting options to your image so you can see the ring better.
How do you think the image would look if you crop the black line underneath leaving you with only one background color/material?
I appreciate the fact that you show the progression of the smoke rings in one image.
I like how you can see the direction of the rings as they fly across the frame. The direction gives a sense of intention and care when taking the picture.
How far away were the smoke rings and the table from the camera?
I like the flow physics you captured, specifically the instability of the left vortex can be seen developing into a wavy shape before it breaks down completely.
Hey Faisal, Overall very good job. However, I think you can spend more time playing with the lightings, shadows, and other background stuff to make it perfect.
I love seeing the different stages the rings are in, however I find the glare from the background to be a bit distracting. Did you consider creating a more neutral background?
What do you think about the contrast of the wood background with the smoke rings?
I really like the contrast between the dark table and the light smoke rings. I know that it can be hard to capture smoke rings, especially several in one image, but you were able to achieve it. It would have been interesting to see a time lapse of one ring!
It is great how the picture shows multiple smoke rings in multiple stages. I think if the background was just the wooden color that would make the picture better.
I enjoyed how the picture shows the different stages of the vortex from formation to dissipation.
To capture the fog from the vortex ring seems to be a hard photograph to take in 10 seconds. The multiple rings from the tapping from a balloon seems to be an excellent idea! The shutter speed might have been short 1/25 f5.0. The aperture is small and things should be in focus, put a object and manually set the focus, before taking the photo.
The rings are prominent in the photo, but what do you think about the shutter speed length?
I like that we can see the rings are at different stages of dissipation and the contrast between the white and dark wood in the background.
I appreciate how the vortex rings show a transition of laminar flow at three different stages
I think the fact that you created this smoke ring contraption by yourself with your own material. I really like how you captured two rings as opposed to a single ring. It shows multiple phases of the ring formed together and then beginning to dissipate.
The focus could have been adjusted a little bit to fit more the smoke rings. However, the beauty of the image is undeniable.
I like the multiple rings in the image. It gives the image a sense of progression of the rings.
It’s really a good picture, I like how you were able to make a ring of smoke using only a bottle. Also, having a black background was helpful to make the rings look crystal clear.
The use of colors with the background gave an almost black and white feel to the picture, even though this is a full color photograph. It gives a unique aesthetic that helps the focus of the photo (the smoke rings) stand out.
I appreciate the evolution of the smoke ring, from almost a perfect ring in the first picture to a dissipation in the final stage.
I really like the idea behind the photo! But I think the background is too distracting, a total black background could have made the flow much more recognizable and prevented the focus to be on the wood instead of the smoke.
I like how the smoke rings are at the bottom of the picture, the contrast of the background really makes it pop
It is very interesting to see the trail coming from the center of the vortex ring. This does show the interesting fluid mechanics of the vortex and can tell us the direction of the spin of the ring as well as its direction and even perhaps speed.
I could recommend using a “cleaner” background that is a solid color to avoid any distraction from the smoke subject. But I do think you could argue that it adds an aesthetic.
I have an opinion about the focus of the photo. Would you like to hear it?
What do you think about the way the light reflects off of the wood in the background? I like the texture the background adds to the image.
I like your choice of background, although it may be a bit distracting when trying to look at the smoke rings since that is the main focus.
The capturing of the transition is fascinating in terms of being able to see it dissipate!
The focus is on the background not the smoke rings.
This photo beautifully shows good utilization of the rule of thirds.
What do you think about the change in background on the bottom where the rings are?
The smoke rings are really cool, but I wish you used a less distracting background- i.e. a black sheet that was consistent behind the smoke rings so the viewer’s attention is solely focused on the smoke.
