Francis Bacon
CINEMATOGRAPHY
Muybridge chalked lines and numbers on a board behind the track to measure progress. As Stanford's horse raced on the track, it tripped the wires and recorded 24 photographs that proved that all four of the horse's feet were off the ground at the same time.
Stanford won his bet, and Muybridge continued experimenting. During the early 1880s, he traveled to Paris to demonstrate his multiple camera system for other photographers and scientists. One of his hosts was Etienne Jules Marey, who was experimenting with the use of a single camera for recording images in motion.

Fluorescence Digital Imageing
The word Angiography comes from the Greek angeion, "vessel" and graphien, "to write or record". Angiography is the imaging of vessels, and the resulting pictures are angiograms. Angiography of the retina of the eye requires the injection of a small amount of dye into a vein in the patient's arm. The dye travels through the blood stream and is photographed using special cameras and colors of light as it travels through the vessels of retina.
Fluorescein Angiography is performed with a dye called Sodium Fluorescein. When illuminated with a blue light, the fluorescein dye glows or fluoresces in yellow-green. Special filters in the camera allow only the fluorescent yellow-green light to be photographed, producing high contrast images of the retinal vessels. Fluorescein angiography can be performed using either standard black and white photographic film or using digital cameras.The first time i did FFA I was absolutely amazed that how fast the dye circulates around the body. 5 to 8 seconds after the fluorescein has been injected I could start taking the photographs.
Indocyanine Green (ICG) dye is used in conjunction with infrared "light" for angiography in very special cases where fluorescein angiography proves inadequate. Because infrared energy is not in the visible spectrum and can not be imaged well with photographic film, high-sensitivity digital cameras are used for ICG angiography.

3D world!
We live in a 3D world , and we become aware a 3D world. However, how we actually achieve 3D vision is a mysterious psychological question. After all, we only have a 2D retina , so where does the extra dimension come from?
To be continued ....... more information will be add to this section....
Eadweard Muybridge
He bridged the gap between art,science,and technology with with his thousands of sequences of motion photographs.

Lennart Nilsson
LN: We put in a light with the fibers all the time. And sometimes we put in another light from the side too, when we have space. But the piece I just worked on in Göteborg was unbelievable. The fetus was moving, not really sucking its thumb, but it was moving and you could see everything—heartbeats and umbilical cord and so on. It was extremely beautiful, really beautiful! And I did some panning ... I was extremely satisfied with the 0.8. So this is a new way.

Topcon TRC-50IX
Topcon TRC-50IX
Topcon TRC-50IX The ultimate camera for all photographic applications! This tri-functional camera sets the standard for ICG, fluorescein, and color imaging, and is designed with the added flash settings necessary for today's sensitive digital cameras. A large eyepiece and alignment dots enable the photographer to easily and comfortably align the camera. Superior optical coatings eliminate flare and assure maximum image quality.
A modern fundus camera system is a semi-mobile floor mounted ophthalmic instrument costing £50,000.This complex system is used to produce high-resolution photographs of the patients retina.
I used this camera to take Fundus photographs. Fundus is the bottom or base of anything. In medicine, it is a general term for the inner lining of a hollow organ. The ocular fundus is the inner lining of the eye made up of the Sensory Retina, the Retinal Pigment Epithelium, Bruch's Membrane, and the Choroid. Basically this type of photography involves the patients head to be immobilized and the camera positioned close to the eye.So I have to observes the retina by adjusting illumination and carefully positioning the eye using external and internal fixation points.

Emotion and Motion in human body
“Vision itself is a dynamic process. There is little in the world that stands still, at least not as imaged in our retinas, for our eyes are always moving. The visual system is almost exclusively organized to detect change and motion.” Haldan K.Hartline
Hartline,H.K.1972.’Visual receptors and retinal interaction’ In Nobel lectures,Physiology or Medicine 1963-1970.Amsterdam:Elsevier Publishing Company,P.281
The eye is free to explore the space it inhabit. It flicks, glances, pans, tilts-all in, literally, the blink of an eye.
Our eyes provide us a magical picture of the world. They record every moving image unlike the camera they don’t record what is really out there.They highlight the things we are interested in, enhance them in countless ways, and always put the object with the most interest in the middle of the frame
How can I show this beautiful part of body which invisibale to the naked eyes?!
I quite often ask myself what is so essential to our experience and our behaviour? I think emotions are central to human experience and behaviour.Our feeling and passions are so essential to our experience and our behaviour and they can condition the way of dealing in different situation and in all forms of communications .
It is by combining successive attitudes in to a single pose that a work creates the illusion of movement: ”If people in photographs, caught in action, seem suddenly frozen in midair, it’s because of their body are reproduced in the same precise fortieth of a second. And so they lack the progressive unwinding of a gesture that we find in art”
Auguste Rodin,19II
The body in motion is expressed as a transformation, from one shape to another.looking at human motions i came across a few artist which I am going to look at them: the german Renaissance artist Albrecht Durer,Edward Muybridge
References : Philippe Comar ,The Human Body Image and Emotion ,1999,Thomes & Hudson Ltd,London
The more I research about this subject the more i came across lots of questions!Questions of appearance and representation are central to regarding emotions as emerging from motion: How do emotions present themselves? How are they represented in motion? Whatis their relation to the specific media contexts of the arts – how can an embodied relation with,for instance: a printed text or a two-dimensional image, be conceived of and habitualized? Howare embodied emotions brought into visibility, audibility or readability? How can media processes? How could i Record that with my photography skills?!
I am hoping to find answers to these question by end of this project!
Eyes and movement
One of the less obvious, but extremely important common features of our eyes, is the way they move, either by themselves or as part of a moveable head or body.
I would like to record this movement with my photographic techniques by producing a set of Anaglyph images in which they‘ve been used to provide a stereoscopic 3D (3 dimensional Imaging effect), when viewed with 2 color glasses.
Humans are foragers;we take a more than visual interest in what things are.But even our eyes are tubed,first and foremost,to motion.In 1875 the Viennese physiologist Sigmund Exner showed that two brief,stationary dots into moving objects makes a great deal of scene in nature,where prey and predators disappear and reappear constantly,as they move through glass ,run behind trees,and peer around rocks.Every film and TV programme ever made depends on the power of phenomena (called the phi phenomenon).Both display still images quickly enough for our eyes to read them as a single moving image

Eyes and Science
Personal background and Inspiration
Medical Photography at Whiston hospital is part of the Plastic & Burns Unit. I commenced photographing people/patients. I loved the idea of being able to present the facts visually for benefit of both the doctor and patient using the medical techniques; however It wasn’t always a pleasant situation .My interest in this science has lead me to develop and combine my two loves, looking at the narratives with the technical expertise. My main inspiration was Lennart Nilsson who is regarded as the greatest scientific photographer in the world. For my final project I focused on human’s skin and looking at this creation with a microscopic view, so this project is an extension from there.
Recently I have been employed by St Helens and Knowsley Trust as an Ophthalmic Photographer. Before I began this job, I had never taken into account how much we take our visual abilities for granted. The more I learn about the eyes, the more I realize how fascinating, amazing and mysterious it is.
For me photographing eyes is a new world of photography and by end of this project I am hoping to be able to show part of this mystery!
