Structure of Rose, photo by Harold Davis. View this image larger.
As flowers go, roses tend to present interesting three-dimensional curvilinear spaces. Looking head-on at a rose is different in scale but otherwise similar to an aerial view of badlands or canyon country.
I picked both roses out at a local florist, and used bright, but overcast sunlight. There was a blind on the window so I could control the intensity of the light.
Both photos are examples of hand-HDR and flower photography—I combined multiple captures at different exposures using layers and masking in Photoshop to create each final image.
