At least one storage device having encoded thereon instructions which, when executed, perform a method comprising:
- detecting a first region and first position reference information, the first region being a region with contrast in a first image of an object for observation which is photographed under illumination with visible light, the first position reference information relating to a position of one or more features of the first image, wherein detecting the first region comprises detecting at least one border of the first region using one or more digital filters;
- detecting a second region and second position reference information, the second region being a region with contrast in a second image of said object for observation which is photographed under illumination with ultraviolet light, the second position reference information relating to a position of one or more features of the second image, wherein detecting the second region comprises detecting at least one border of the second region using one or more digital filters;
- defining, based at least in part on the first and second regions and the first and second position reference information, a specimen region, encompassing the first region and the second region, where there exists a specimen in the object for observation;
- and
- in response to the defining of the specimen region, causing at least a portion of the specimen region to be photographed.
