Kaleidoscope Experimentation
Base Image
I cropped the image so when I duplicate it it will connect up
I then changed the canvas sizes’ width to be double
I filled in the blank space with red so I can see later if there is any gaps between the images
I selected the red area with the magic wand selection tool and did an inverse select so it would select the image instead
Then I duplicated the layer, moved it over the red space and flipped it horizontally and then flattened the image
Then I doubled the height of the canvas
There is a gap in the middle of the image because you can see a red line so we have to make the image overlap
Then i cropped the image so there is no more red showing
I duplicated the image and flipped it 90 degrees
Then I flicked through the blending mode until i found one that looks good
I repeated this process
