Floral experiments

Changing colors in flowers are attractive, especially if you approach them closely. A group of 3 flowers looks like communicative group. With targeted overexposure and instant images on the laptop, the compositional decision is easier and the colors become more picturesque, without too much processing with the computer.

Photography of flowers in a vase in an exposure series (HDR) is complicated by their light sensitivity, which causes a change of position in short time scales. Plants constantly rearrange their leaves and blossoms. This results in blurring, which can be compensated for e. g. by repeating the shot series, shorter exposure time series or tools for aligning the images. Or you can do your image without HDR, because the dynamic range of the camera data is sufficient.

The center of a Gerbera blossom is richly structured. Due to the high resolution of the camera back (150 MP), it is possible to crop out the center still in good resolution.

The transparent representation of the petals is achieved by using a light box. The light should be relatively bright, but does not have to be fully homogeneous. The heat of the light does not matter, it is adjusted using RAW format in post-processing. More informations about this method see web-pages of Harold Davis, who invented this method.

I like to make things visible the naked eye isn't able to see. That's part of my profession as a radiologist, too.
