This image displays the Background Oriented Schlieren effect of a flame. This image is specifically showing the air density gradient when the flame is lit, created by comparing the flame at two different moments in time. This image was created with help from Josh the Engineer who has a great blog post here: https://www.joshtheengineer.com/2019/10/20/how-to-take-pictures-like-nasa-using-background-oriented-schlieren-bos

I really enjoy the sharp black outline of the hair dryer and lighter and how it contrasts with the colors of the density gradient. Cool photo!
The color scheme that you used does match a “temperature” profile pretty well! If we could record the temperature in all areas of the image, I would be interested to see how it lines up with the “temperature” profile colors you included in this image. Would the hottest areas of the image be the red part of the image? Would the coldest areas be where there is blue?
