Photography the scientists retina: ver 3.0
Digital imaging and image processing means that we now have capabilities far beyond what was possible with silver technologies including; High dynamic range imaging (HDRI), stitching and focus stacking and combinations of these techniques. This presentation will show examples of what is possible and how photography can aid your research and its visual impact. “The sensitive photographic film is the true retina of the scientists . . . . for it possesses all the properties which science could want; it faithfully preserves images which deposit themselves upon it, and reproduces and multiplies them indefinitely on request; in the radiative spectrum (electromagnetic spectrum) it covers a range more than double that which the eye can perceive and soon perhaps will cover it all; finally it takes advantage of the admirable property which allows the accumulation of events, and whereas our retina erases all impressions more than a tenth of a second old, the photographic retina preserves them and accumulates them over a practically limitless time.” P.C.Janssen 1888 Version 1.0 Silver technology Version 2.0 The New Photography from 1895 i.e. X-rays Version 3.0 The development of digital image processing

Notes de l'éditeur
- To begin with all that digital photography was doing was replacing film with a chip. Version 3.0 has moved on massively from the original digital cameras which in all honesty looked just like film cameras. Need view of Nikon F90 from above compared to D7000
- Video of back of a D7000 or other showing Intervalometer built in.
- This order is kept if only Stack and Stitch
