Droste Effect Sunflower. Created with the Mathmap GIMP plugin and the Droste script by Josh Sommers.
How it's done:
Starting with a sunflower photo with a nice plain sky background I
used the select by colour tool to select the background. Then by
promoting the background layer to a proper layer I cut out the sky to
leave the sunflower on the transparent checkerboard. On the first go
with Mathmap I found the petals still had bright edges because they
used to be against a bright sky, which looked wrong against the dark
flower centre. So I went back so the selection stage, grew the
selection by 3 pixels so it cut off the edges of the petals and then
feathered it by 3 pixels. Then I cut the sky off. Now I had just the
flower with gradual transparency around the edge. I grabbed a nice
brown from the middle of the flower using the eyedropper and created a
new layer under the flower layer filled with that colour. Then I
flattened and again cut out the flower from the background using fuzzy
select this time. Now at last I had a flower with a brown fringe
around the edge.
Finally I stuck it in Mathmap, selected Droste and turned on ExternalTransparency because that's what it has. Tweaked the parameters and here is the result.
Parameters:
InnerRadius 29.56
OuterRadius 91
Periodicity 1.02
Strands 1
XCenterShift 2
YCenterShift -4
StartingLevel 5

Wicked effect - gotta see it bigger for best. Is it intentional that all the green leaves are in the lower half?

Bigger and then zoom in on the middle and it's like you're not zooming at all! It just gets more pixely. The leaves are in the lower half because that's where they were in the original. They start to twist within the spiral. If you could keep going then they'd go all the way round.

I don't know if you know this, but someone on tumblr seems be saying it is a real flower from the UK. They are crediting you for taking a photo of it.

Fine by me as long as it's credited and linked. :)
