I could not have taken this with my DSLR, at least not without damaging the tulip.
I could stick the small lens of the GRD through flower leaves and take the photo.
Arend, what a great macro shot. I like much the geometric pattern. Like Sandy said, it looks like a kaleidoscope art. First one with GRD3? So you will make even better? Cannot wait for more then.
Having shot many similar shots myself, I have wondered how you managed to engineer (or to construct the appearance of) uniform lighting across the entire surface of the subject (as the camera at such an evidently close distance would seem to block some of any light that arrived from behind the camera).
I considered that you may have used the camera's on-board flash - but the light does not show evidence of arriving from any particular angle relative to the center of the lens itself. Further, it does not appear that the lighting arrived from behind the body of the tulip, either (though I am not sure about that). The inner portions of tulip petals are semi-translucent (an optical property that I use to photograph the inside of the tulip when sunlight is shining on the outer surface of the petals of the tulip, and correspondingly illuminating the inside of the tulip).
No need for you to disclose and proprietary procedures here (should you prefer not to) ...
At any rate, observing the Histogram in PaintShop Pro 9.011, I see that your image has very high mean and median (composite) luminance. I found quite a bit of interesting details in your image that emerge by reducing the Brightness - accomplished by shifting the white-point downwards while maintaining a zero-valued black-point (thus linearly scaling the histogram components downwards). Have you played around with post-processing it? The EXIF data indicates that it is an unaltered in-camera produced image. It would be interesting to see what such post-processing might do for an already robust image.
@ Detail man, I have no big secrets behind this image and quite some luck with the circumstances (e.g. light)
First I tried with the onboard flash but indeed that gives an uneven lightning.
Then I have put the tulips outside and tried without flash. At this low ISO (64) and literally putting the lens in the flower I still had just enough light to get a sharp picture without tripod (1/24s at f4, but it took me a few shots to get a decent one).
What helped is that I shot in DNG and later developed in Capture One. I did not change exposure but increased contrast a bit and saturation quite a bit.
