First Prize – I love how the fluid spikes up with movement and the different colors in the photo contrasting with the black background.
THIRD – I really appreciate the contrast and the way the colors pop. I’m also impressed by the negative space and the way the motion of the paints is captured against the black background.
Second prize – I really like how the different paint colors react to the induced acoustic ways to create a wonderful flow effect with a ton of visual appeal. It looks like an incredibly fun and interesting image too, which I really like!
Second Prize – Honestly this is just super cool. The way that they were able to separate the colors so clearly is astounding and its just super fun to look at.
Third Prize – I love how the dynamics and the vibration of these fluids show contrasts and beautiful colour saturation.
First Prize – I’m really impressed by how separated the colors remain, and the motion of the paint combined with the clear focus really highlights the displacement caused by a speaker.
Second Prize – I love the mix of colors and how clearly they are separated and contrast well with the black background. The clarity is also done very well.
