No tricks of Photoshop here. A just by chance combination of depth of field and the angle the butterfly is positioned, and perhaps its dark colouration, gives a three-dimensional impression to this image. I think it does, anyhow. Can anybody else see this, or it just me?

Yes, I agree it seems everything came together to give a really nice 3D impression. I used to run across this many years ago when shoot Kodachrome slide film indoors with a flash. It occurred mostly with dark red objects. I think the combination of background separation due to depth of field and contrast are responsible. It was always a pleasant surprise because I was never trying for a 3D effect.

Thank you for your interesting comment, David. I hadn’t even noticed this before, and I had taken the image back in 2007! I can imagine these surprises for you and your shooting, because it was for me!

The wings seem curved towards the viewer. Is that a trick of the light too?

It might be a a combination of the light reflecting off the bottom of the wings and the perspective, but I hadn’t noticed until you pointed it out, thank you 🙂
