Art: I love the warmth coming from the pot, the condensation from the pot really makes it nice to look at!
Flow: There’s dissolved oxygen in coffee beans that gets released that provides the condensation when being made in a coffee pot.
Photographic Technique: Maybe make it more symmetrical, but the focus on the coffee is nicely done!
I really like that you are able to tell how warm the coffee is in the picture, the background with how steamy the pot is it really cool. I like the focus of the picture as well.
This is a good idea for a flow phenomenon. I like the warm background color and the narrow field of view. Try capturing the bubbles more close-up for a more fluid-focused photo.
Nice! Your image does a great job illustrating the turbulent flow caused by the drip as well as the warmth of the coffee itself. How close was the camera from the carafe? The condensation on the sides of the container seem to distort a lot of your image which would otherwise be in focus. You could try using a cooler liquid, but then again I like how it contributes to the feeling of warmth, along with that orange shape in the background. Would a liquid other than coffee demonstrate the same phenomenon of releasing oxygen into the bottom of the carafe?
You mentioned in class that when water is initially poured onto the coffee it releases some oxygen. IT might be a cool experiment to see if you could capture that flow release rather than just the filter final product.
I like how there’s an isolated pocket of bubbles which Is the only thing focused on in the image. I also think that if you closed the windows a little bit to prevent the glare on the glass.
This was a really interesting presentation, I didn’t know the physics of coffee beans and their oxygen content. I also think the steam on the far wall of the glass is really interesting. It itself has a unique pattern and it has a cool diffusing effect on the light reflecting off the objects in the background.
The idea here is pretty neat, I wouldn’t have thought of it. I liked how you framed the bubbles and unfocused the background so the coffee was clearly the focus. Also enjoyed the info about the oxygen stored in coffee beans. Yay coffee, good job!
I think the framing could use a little work. Maybe crop it on the right. I like the swirl of the foam but maybe put more contrast in it.
The physics of this is pretty cool. I like how you centered the falling fluid. Maybe crop some of the higher exposure on the left side of the photo.
The warmth and blurriness of the background are great being that this is coffee, I think that it adds to the image. I think that a slightly larger depth of field would add to the picture so that more of the bubbles would be clearly visible.
This is a warm image. The bubbles are a nice caramel color. I was wondering what is the focus of the image? Is it the stream or the bubbles?
Great image! I think the difficulties of focusing is the biggest issue here. The light coming through the back of the coffee pot is cool as it passes through the condensed water on the side of the pot. The color of the bubbles on the dark coffee adds a good warm feeling to the image. Well done.
It’s a good composition in this image. The bubble above the coffee is cool.
The idea is great. The bubbles are clear but maybe another angle would better to show them. The back ground is well thought of. Great work on the picture and the idea.
Given the shooting conditions I think you actually caught a pretty clear and pleasing image and I like the natural contrast between the coffee and the bubbles is great! I think some lighting underneath the pot would help you capture a clearer image of the stream entering the pool of coffee but definitely try to maintain the neat steam distortion effect!
I like how you are using coffee for this image, it’s a very dark fluid and it makes you focus more on the top layer of the fluid. You can see all the condensation and it makes the outside of the glass have a nice warm distortion.
The glare in the foreground is a little distracting. I wonder if you could crop it differently or take the image in a different way. The bubbles are a little blurry, maybe they could be more in focus. I like that you can see the condensation.
Nice! I liked how you could see the coffee entering the cup and how the rest of the fluid is pushed out to the side. The color scheme of this image turned out really well. If it’s possible to get a sharper image of this, I’d love to see it again
I like the different colors in the image. The bubbles looks awesome. The background is blur which helps to catch the attention on front object.
I like your inspiration of photographing something you see every day, but now you are making the image larger. It’s nice how simple and natural this image is. Maybe in the future try photographing the drip from the maker itself into the pot.
I think this is an interesting image! I think you mentioned that you liked seeing the bubbles as the coffee goes down, but I think it’s a bit blurry – I might suggest trying to get more of the image in focus. I love the back wall of the glass, and I think that creates a really cool effect.
I like this image because it is relatable. The oxygen bubbles are a cool effect and the reflections in coffee are aesthetically pleasing.
This image is depicts something that most of us do every-day but don’t really think about. I find the colors a little dark for my taste, I feel like some color inversion could show the details you would like to bring out a little more. The condensation shows a very cool effect.
It shows the bubbles well, but is a bit out of focus. I like the color of the bubbles compared to the dark liquid. Maybe you could play with the reflection and focus a bit more. Otherwise it looks quite good!
Perhaps a little bit more practice with the focus, but the image of the hot coffee with bubbles gives a certain warmth to both the image and the audience.
Like the nice warm feeling that can be taken from the photo. Like the oxygen coming from the dripping. Could get a clearer photo though.
I take it you like coffee? Blose up on bubbles with such a dark background is actually a great thought! It would be cool to get a better and closer focus on the bubbles themselves and remove everything else from the frame.
