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.
