[edit]DescriptionKarpvähiline0424.jpg |
Eesti: Magevee karpvähiline perekonnast Heterocypris (Heterocypris sp.) pildistatud mikroskoobi all kasutades 8x objektiivi. Isend on kogutud Rakvere linna tiigist 2024. aasta aprillis. Pildil on selgelt näha karpvähilisele iseloomulik kahepoolmeline karp, mis on poolläbipaistev ning omab rohekaskollakat värvust. Eriti hästi on näha karbi servas paiknevad peened karvakesed ning iseloomulikud tundlad. Karbist väljaulatuvad tundlad on karpvähilistele olulised liikumisorganid.
Pilt on tehtud musta tausta peal, mis toob eriti hästi esile looma poolläbipaistva kehakatte struktuuri ning õrnad jäsemed. Valgustamisel ei ole kasutatud mikroskoobi tavapärast läbistavat valgust, vaid peegelduvat valgust, mille allikaks on fotograafia välklamp (speedlight). Selline valgustuse lahendus võimaldab tuua esile objekti pinna tekstuuri ja läbipaistvaid struktuure erilise detailsusega. Pilt on tehtud kasutades fookuse virnastamise tehnikat (focus stacking), mis võimaldab saavutada suure teravussügavuse ka mikroskoobi all pildistades. See tehnika on eriti oluline mikroorganismide pildistamisel, kuna võimaldab saada teravad detailid nii objekti lähemal kui kaugemal asuvates osades.English: A freshwater ostracod of genus Heterocypris (Heterocypris sp.) photographed under a microscope using an 8x objective. The specimen was collected from a pond in Rakvere, Estonia, in April 2024. The image clearly shows the characteristic bivalved carapace of the ostracod, which is semi-transparent with a greenish-yellow coloration. The fine setae along the edge of the carapace and the characteristic antennae are particularly well visible. The antennae extending from the carapace are important locomotory organs for ostracods.
The specimen was photographed against a black background, which excellently highlights the semi-transparent structure of the animal's carapace and its delicate appendages. The lighting technique used differs from conventional transmitted microscope illumination - instead, reflected light from a photographic speedlight flash was used. This lighting solution allows for exceptional detail in revealing the object's surface texture and transparent structures. The image was created using focus stacking technique, which allows achieving great depth of field even in microscopic photography. This technique is particularly important when photographing microorganisms, as it enables sharp details to be captured in both the near and far portions of the subject.العربية: نخريات المياه العذبة من جنس Heterocypris (Heterocypris sp.) تم تصويرها تحت المجهر باستخدام هدف 8x. تم جمع العينة من بركة في راكفير، إستونيا، في أبريل 2024. وتُظهر الصورة بوضوح الدرع ذو الصدفتين المميز للصدفيات، وهو شبه شفاف مع لون أصفر مخضر. تظهر الشعيرات الدقيقة على طول حافة الدرع والهوائيات المميزة بشكل جيد. تعتبر قرون الاستشعار الممتدة من الدرع من الأعضاء الحركية المهمة للصدفيات.
تم تصوير العينة على خلفية سوداء، مما يسلط الضوء بشكل ممتاز على البنية شبه الشفافة لدرع الحيوان وملحقاته الدقيقة. تختلف تقنية الإضاءة المستخدمة عن إضاءة المجهر التقليدية - وبدلاً من ذلك، تم استخدام الضوء المنعكس من فلاش Speedlight الفوتوغرافي. يتيح حل الإضاءة هذا الحصول على تفاصيل استثنائية في الكشف عن نسيج سطح الجسم وبنيته الشفافة. تم إنشاء الصورة باستخدام تقنية تكديس التركيز، والتي تتيح تحقيق عمق كبير للمجال حتى في التصوير المجهري. تعتبر هذه التقنية مهمة بشكل خاص عند تصوير الكائنات الحية الدقيقة، لأنها تتيح التقاط تفاصيل دقيقة في كل من الأجزاء القريبة والبعيدة من الهدفPilt on tehtud musta tausta peal, mis toob eriti hästi esile looma poolläbipaistva kehakatte struktuuri ning õrnad jäsemed.
