S.:Die Möglichkeit der Auflichtfluoreszenzmethoden bei Untersuchungen von Zellen in Durchströmungskammern und Leightonröhren. Xth Symposium d. Gesellschaft f. Histochemie, 1965. Acta Histochem. Suppl. 7, 339–343, 1967. Ploem, J. S.: The use of a vertical illuminator with interchangeable dichroic mirrors for fluorescence microscopy with incident light. Zeitschr. f. wiss. Mikroskopie 68, 129–142, 1967. However, micrographs were acquired on colour film, but it's not clear if that was double exposure on the same frame. _________________________________________ Philippe Laissue, PhD, Director of Bioimaging Unit School of Biological Sciences, Room 4.17 University of Essex, Colchester CO4 3SQ, UK (0044) 01206 872246 / (0044) 07842 676 456 [hidden email] privatewww.essex.ac.uk/~plaissue On 25 June 2014 08:30, Jeremy Adler <[hidden email]> wrote: > ***** > To join, leave or search the confocal microscopy listserv, go to: > http://lists.umn.edu/cgi-bin/wa?A0=confocalmicroscopy > Post images on http://www.imgur.com and include the link in your posting. > ***** > > Out of curiosity and wanting to give the correct citation, does anyone > know when and where the first overlay image was published ? > Overlays typically put different images into separate layers of an RGB > image to show areas of overlap. > > My guess is the early 1990s, possibly limited by the charges made for > colour printing, so references to the use of overlays, even if not printed > would also be interesting. > |

Certainly in 1854 John Snow created a coloured overlay map showing the location of Cholera victims deaths overlaid onto a street map of Soho in London which enabled him to correctly identify the source of the epidemic (a water pump in Broad Street). Coloured overlays were regularly created manually using tracing paper (invented in 1809) or sheet glass, which may or may not have been photographed in colour. Microscopes that can overlay images from two different samples (one head, two microscopes), i.e. the bridge or comparison microscope, was regularly used with photography, e.g. in 1929 Goddard's comparison microscope was developed for forensic ballistics in order to compare two bullets thought to have been fired from the same gun (and modern colour camera variants are still used for this today). Back in the 1969 the Quantimet 720 image analyser was introduced that overlaid a single orange coloured binary thresholded image over that of a digitised B&W image captured from a microscope, following on from pioneering work in the 1960s regarding digitising and quantifying images from the microscope, although typically the images analysed were B&W (as indeed are our fluorescence images today). Given that Disney created triple B&W silver grain film masters of his original colour Snow White film, one each for the red, green and blue channel, back in the 1930s, seems likely that those 1960s digital pioneers also experimented with RGB colour overlays. So the first multi-colour overlay was no doubt created a while ago, the exact date probably lost in history and also depending on how you define 'colour overlay' (normal fluorescence microscope R-G-B layering typically only works with up to three B&W channels, so you could easily go beyond that today with say up to 8000 layers in Photoshop CS6). Interesting question. Regards, Keith *In fact it is likely that Thomas Wedgewood (son the Josiah the potter and a relation of Charles) took the first B&W photo of an image down a microscope around 1799, as the Solar Microscope, an magnifying variant of the Camera Obscura, was also available to him, but sadly Thomas couldn't find a way to fix the photographic image and so make them relatively immune to effects of light. Some of Thomas's unfixed photos did survive at least to the 1890s as his B&W photographs didn't fade if kept in total darkness. Thomas's pioneering photographic work was published by his friend Humphrey Davy in 1802. ----------------------------------------------------------- Dr Keith J Morris Cellular Imaging Microscopy Core, The Wellcome Trust Centre for Human Genetics, Roosevelt Drive, Oxford, OX3 7BN, United Kingdom.

We double exposed slide film with images collected from FITC and Texas Red. Just changed filter cube and re-exposed the same piece of colour slide film. Where the image became orange/yellowish was the overlapping signal. I don't think it was the first lab to do this. But it was fun! Look in the journal "Cell" around that time.
