About the Nikon Small World Competition
The Nikon Small World Competition was founded in 1975 with the aim of recognizing excellence in photomicrography, which is the art and science of capturing images through a light microscope. Over the decades, it has grown into one of the most respected competitions for scientists, artists, and imaging professionals working at the intersection of science and visual creativity.
The competition accepts entries captured using a wide range of light microscopy techniques, including:
- Phase contrast microscopy
- Polarized light microscopy
- Fluorescence microscopy
- Interference contrast microscopy
- Dark field microscopy
- Confocal microscopy
- Deconvolution microscopy
- Mixed or combined light microscopy methods
In addition to still images, the competition features a Small World In Motion category, which accepts digital videos and time-lapse microscopy footage. This category gives participants the unique opportunity to capture dynamic processes unfolding at the microscopic level, adding a new dimension to scientific storytelling.

Application Deadline

Selection Criteria
The Nikon Small World judging panel assesses entries based on a combination of scientific significance and visual artistry. Here is what the judges typically look for:
- Scientific relevance: Does the image reveal something meaningful, new, or significant about the microscopic world? Images that communicate scientific value alongside visual appeal tend to perform well.
- Technical skill and execution: The judges evaluate the quality of the microscopy technique used, the sharpness and clarity of the image, and the entrant’s command of their equipment and method.
- Originality: Is the subject matter fresh, unexpected, or creatively framed? Entries that present familiar subjects in surprising ways or capture rarely seen phenomena stand out.
- Aesthetic composition: How well is the image composed? Judges look at lighting, color, balance, and the overall visual impact of each submission.
- Video dynamics (In Motion category): For video entries, the judges assess the quality of motion capture, the clarity of the dynamic process being shown, and the narrative value of the footage.
- Compliance with rules: Only submissions that meet all the technical and ethical requirements of the competition will advance through the judging process.
Important Tips for a Winning Entry
- Use the best equipment available to you: Image clarity and resolution matter enormously. If you have access to advanced microscopy equipment at your institution, make the most of it and ensure your camera settings are optimized before capturing your images.
- Choose your subject wisely: Look for subjects that are visually striking and scientifically interesting. The most memorable competition entries tend to combine beauty with meaning, showing the viewer something they have never seen before.
- Submit your maximum allowance: You can submit up to 3 still images and up to 3 videos. Use all your available slots to maximize your chances. Each submission is an independent opportunity to impress the judges.
- Write compelling descriptions: The description you provide for each image is your chance to connect the judges emotionally and intellectually to your work. Explain the subject, the technique, and why this image matters, clearly and concisely.
- Avoid AI-generated images entirely: Any entry using AI-generated imagery will be disqualified immediately. Ensure that every element of your submission is captured and processed by you using a genuine light microscope.
- Do not submit previously awarded work: If an image or video has already won an award in another photomicrography competition, it is not eligible. Review your portfolio carefully before selecting your submissions.
- Submit early: Do not wait until the 30 April 2026 deadline. File upload issues, internet disruptions, or portal traffic can cause last-minute problems. Submitting a few days early removes this risk.
- Review the official rules before submitting: The competition has specific technical and ethical requirements. Read through the full ruleset on the official portal to ensure your entries comply on every point before you submit.
- Consider time-lapse or video submissions: The In Motion category is highly regarded and competitive but still has excellent prizes. If you have captured compelling microscopic processes on video, consider entering this category as well.
