When photographing “almost” flat surfaces quality and direction of light plays a major role in getting textures within our subjects right – more so in macro photography. See the above image and the same one below. The only difference is the direction of light used. For the above I used light falling on the subject in a oblique angle and for the one below it is front light.
See the difference !!
Why oblique angle of light made so much of difference ? It is because “texture” is characterized by fine play of light and shadows as shown in below two small crops (100%) of the above images.
Next time when you are photographing almost a flat surface give it a consideration for angle of light falling on your subject !!

Some time back I had a request for a few high resolution images of critically endangered vultures found in India by a non profit organization. It may be noted that the population of vultures have drastically declined in India thanks to use of diclofenac by cattle farmers to treat cattle diseases which is highly toxic for vultures which feed on the carcasses of dead cattle. This particular organization was planning to use images of vultures to make posters for creating awareness amoung people to protect them.
After giving some of those images to them it occurred to me why not make all my images of subjects in nature which are labeled by as either Near Threatened, Vulnerable, Endangered or Critically Endangered by International Union for Conservation of Nature (IUCN) for use by non-commercial organizations working towards conservation of nature ?
This lead to quick scanning of all my images and tagging them with these key words for faster search of endangered subjects that I have photographed.
If you are a non-profit organization working on nature conservation and if you are looking for any of these high quality images I will be glad to donate them for free for this cause of conservation.
