Bumping to a 10. Nice job!

Back to comment: Two basic photographic rules are not complied with in this image, the horizon is tilted and the main subject is not well focused. Although the top of the head is in focus, the body and leg are not and that is where the angle relationship draws the viewer's eyes.

Lamp post amongst a sea of triangles
by hsvhoon

Comment:
The lamp post gets lost in the sea of triangles. I would have scored this higher if the lamp post was featured and you found an angle to shoot that would show at least 2 different hues of trianges.

Sailing Angles

Back to bump and comment: The image size is under what is allowable for DPC challenges. With a larger size (640 pixel) and a bit more contrast and saturation, this image would have a lot more pop to it. I do love the composition.

Using Airborne Molecules to capture the MacHaggis Muncher
by Kemptonreporter

Comment:
Back to comment: Airborne molecules are a bit tough to see in a 640-pixel image. Thus, your image shows everything but the challenge topic. However, my vote was based on the image itself with minor influence by whether or not it meets the challenge. With that being said, I have a couple of suggestions for improvement. First, you might want to do a little bit of adjustment in PP, as the Muncher has blown highlights on the left side. Second, I really would have liked to have seen a bit more of the cage on top, as it took me a few seconds to recognize that this was a cage being held up by a stick. I assume the MacHaggis Muncher is a regional character and I hope to read a bit about him in your comment section after the challenge concludes.

Back to comment: Although the spirits shown are a product of a chemical reaction, this image doesn't really convey chemistry very strongly. On the technical side, there are a couple of things that could be done to enhance the appeal of this image. First, the image doesn't really look all that sharp in focus. This could be a result of resizing the image, using a wide-open aperture (shallow depth of focus), or from camera shake from hand holding the camera when shooting in low light. Second, the image could use a little post processing adjustments to bring out the colors.

Wild Iris: God’s Chemistry

Back to comment: Sorry to say but I don't feel that flowers fit the challenge description very well. Even if it did, there are a few technical issues with your entry. First, the image could use a bit more depth of focus so that all of the flowers are sharp. Second, this would have been a nicer image if taken at a different time of day. Since the sun in coming from the left, the tallest flower is casting a large shadow right in the middle of the grouping. If the sun was on the right, this shadow would have been prevented and what shadows would have been produced would have contributed to giving a 3-D effect to the grouping instead of causing a distraction.

Heat - Oxygen - Combustibles

Back to comment: A burning match definitely shows a chemical reaction; however, the subject has a very low creativity factor and the glare from the flame is very unappealing to look at.

Red bubbles

Back to comment: An interesting choice for a chemistry challenge. Bubbles definitely show a reaction between water, soap, and air; however, I think that is more of a physical reaction instead of a chemical reaction. The good news is that I considered this as meeting the challenge when I voted. The bad news is that there are some technical issues with the image that I'm afraid will not help this image score well. First, it is hard to find a bubble that is focused sharply. Did you sharpen your image after resizing? If not, most people at DPC us Unsharp Mask (USM) after resizing their images. Second, the red coloration doesn't really show up all that well in the image. I would suggest a little adjustment in curves or levels to see if this feature could be brought out more. Third, the straight on perspective you used to take the image makes the bubbles look very flat. If you could have taken this shot at a little sharper angle, the bubbles would have had a bit more 3-D effect.
