Photo of the month

We have some very talented photographers in the Quekett, and there are hundreds of their images in the Photography showcase and the Slide showcase in the password-protected Members’ area. This page allows everyone to see some examples of their work, including photos that have received Barnard Awards at our Annual Exhibition of Microscopy. Copyright in these images belongs to the photographers, so please do not copy them without permission; if you contact the Club we can put you in touch with the photographer.

Photographer: Mike Crutchley

Subject: The fungus Pilobolus crystallinus (F. H. Wigg.) Tode on cow dung, showing fruiting bodies. This fungus is nicknamed ‘the dung cannon’ because it can shoot the spore capsule some distance to aid dispersal of the spores.

Photographer: Graham Matthews

Subject: Musculature of phantom midge larva (Chaoborus sp.).

July 2016

Larval paddleworm on Phaeocystis colonyLarval paddleworm on Phaeocystis colony

Photographer: Julian Cremona

Subject: Larva of a paddleworm stuck to the surface of a colony of the diatom Phaeocystis globosa Scherffel. These diatoms form a colony by secreting a ball of gelatinous slime with large numbers of diatoms over the surface. Taken at the Dale Fort Marine Microscopy Weekend in May 2016.

Equipment: Canon EOS 7D Mark II attached with several extension tubes to a 65mm MPE lens held vertically. The MPE lens was set on 5× magnification and with the extension tubes this would make it around 7×. Canon Twin macro flashes were used one above and one below the specimen but offset. A black card was below the stage so a translucent dark background resulted. The digital image was cleaned up with some cloning of detritus and slight adjustment of levels and curves in Lightroom.

Conjugating Paramecium, by Wim van EgmondConjugating Paramecium – sex amongst the Protozoa!

Photographer: Wim van Egmond

DIC image showing conjugation in the protozoan Paramecium, a sexual phenomenon in which paramecia of compatible mating types fuse temporarily and exchange genetic material. During conjugation, the micronuclei of each conjugant divide by meiosis and the haploid gametes pass from one cell to the other. The gametes of each organism then fuse to form diploid micronuclei. The old macronuclei are destroyed, and new ones are developed from the new micronuclei.
