Shell with Holes
This is the unprocessed version
This is a segment of the above, enlarged, and processed using the "Wave" (sine) filter in Photoshop.
Shell with Polar Coordinates (original version
This is another detail of the first image with a filter called "Polar Coordinates" applied. If this is used with an asymmetrical image (as this one is), it creates an elliptical image in which both halves are slightly different.
Shell with Polar Coordinates 1
To make this image, I copied the left side, flipped it horizontally, then (carefully!) joined the two to make a symmetrical image.
Shell with Polar Coordinates 2
This is the right side of the original "polar coordinates" image, copied, flipped, and placed as above.
Shell with Polar Coordinates and Twist
This is the image above with the "twist" filter (180 degrees) applied.
Shell Detail with Polar Coordinates
This was made by selecting the bright, central part of the right polar coordinates image, enlarging it, then applying "Polar Coordinates" again. Because the image was symmetrical, it created a symmetrical "polar coordinates" image.
Shell Detail with Polar Coordinates and Twist
This uses the left Polar coordinates image with the "Twist" filter.
Glass Sponge 1
This image of a glass sponge was taken through a magnifying glass to enlarge the detail.
Glass Sponge with Wave
This is the image above with the wave filter applied.
Glass Sponge 2
Another view of the glass sponge through a magnifying glass.
Glass Sponge Twist
The image above with the twist filter applied. Hope you enjoyed these images!
