Amaryllis stamen
These are the stamen of the Amaryllis flower that featured in my last post. Photographing at a very close distance with high magnification presents serious challenges for the photographic equipment. Depth of field is very limited, which means you can only get sharpness on a very small part of the subject. In this case, it was impossible to get each of the stamen sharp at the same time. Luckily, modern photo editing software offers a solution: photo stacking. The idea is to photograph separate 'slices' of the subject, moving the point of focus from the front to the back and merge these 'slices' on the computer to create one image with a large depth of field. The process of recording and merging can be automated using special software, but this image was created manually from 6 separate images, which I stacked in Photoshop.
