Hi all, Someone on the list approved of my posting links to microscope pictures.
Recently I've been subverting my instrument in the direction of 'arty' stuff. I've posted a large gallery of new crystal pictures to my website. There are no 'Back' or 'Home' buttons. To get back one needs to close the page (or tab). I have found that because I'm working with four different servers on three different ISPs I get into an awful lot of trouble with links. I'm trying to sort all this out but putting in navigation is fraught with difficulty (for me) now since after six years or so I have no real idea of what the hell's going on. There are many redundant files and I'm very slowly cleaning up the mess.
The new gallery can be found via the red 'Prints' button on the main page and then by clicking the 'Prints' button on the bottom of the blurb page -- 'mimosa' is faster than 'personal'. All the pictures were made with the *ist D on a Lomo Research (polarising) microscope. Levels were adjusted and in some cases unsharp masking was used to perk the image up a little. There is no camera lens involved. The camera sits on a trinocular head and the image arrives at the sensor via a highly corrected transfer lens. The objectives used were 10/0.25 and 40/0.65 Leitz Fluotars. These objectives provide a completely flat field and are semi-apochromatic. The sensor collects about 50% of the projected field. Mirror lockup (2sec delay) is used and the camera determines the exposure -- set to 'other than A'.
