Microscopy Photo Contests: Where to Enter and How to Win
Microscopy photo contests reward images made through a microscope, and the best-known ones are free or inexpensive to enter. For photographers in the United States and Europe, the main routes are the Nikon Small World competition, the Evident Image of the Year contest, the Microscopy Today Micrograph Awards, society-run contests such as BINA’s, and close-up competitions with a studio or macro-adjacent category. This guide explains what each one offers, who may enter, which rights you grant, and what the judges look for, so you can choose the two or three worth your best frames.
TL;DR
Nikon’s photomicrography competition is free to enter, pays $3,000 for first place and requires a light microscope, with up to three images per entrant.
Other contests have narrower audiences: some are limited to society members or institute staff, so check eligibility before you prepare files.
Judges consistently weigh originality, scientific or informational value, technical skill, and visual impact. A beautiful image with no story or poor technique rarely wins.
Read the licence clause. Most contests let you keep copyright but grant the organizer long-lasting promotional rights.
Deadlines recur on an annual cycle, so confirm the current dates on each official page before you enter.

What counts as a microscopy photo contest
The field sits between art and science. Photomicrography, sometimes called microphotography in everyday speech, means an image captured through a microscope: a crystal grown on a slide, a stained tissue section, the eye of an insect at 20x, a slime mold fruiting body. Some competitions insist on light microscopes only. Others accept electron micrographs, video clips, or reconstructed 3-D data.
Three kinds of competition cover most of what you will find:
Manufacturer-sponsored contests, open to anyone with the right equipment and a strong image. These carry the largest audiences and the strongest editorial visibility.
Society and community contests, often tied to a professional body, with eligibility rules by membership or region.
Institutional contests, run by universities and research institutes for their own staff and students. These are useful to know about if you work inside one, and irrelevant otherwise.
A fourth group deserves a mention: close-up and macro competitions that include a microscopy or studio category. If your work lives at the edge between macro and micro, our guide to macro photography competitions will show you where those images fit.

Nikon Small World
Started in 1975, this is the contest most people mean when they search for microscopy photo contests. According to the official rules, it is free to enter. The cycle that opened on July 24, 2026 stays open until April 30, 2027, which tells you the pattern: entries open in summer and close in spring, with winners announced in autumn. Check the page for the schedule of the cycle you are entering.
Prizes run from $3,000 for first place down to $300 for places 11 through 20, according to the same rules page. A press release on the 52nd competition adds that winners also gain international media recognition. For a deeper walk through the brand’s contests, see our Nikon photo contests rules and entry checklist.
Evident Image of the Year
The sixth annual edition of this contest accepted entries from around the world until January 30, 2026. The prize structure is unusual: the global winner receives an SZX7 stereo microscope with a DP23 digital camera or UPLXAPO objectives, while regional winners in Asia, Europe, and the Americas receive a CX23 upright microscope or an SZ61 stereo microscope. Prizes are instruments rather than cash, so they suit entrants who will keep using a microscope. Expect the next edition to follow a similar winter close; verify on the official page.
Microscopy Today Micrograph Awards
Published by the Microscopy Society of America, the Micrograph Awards include a published category, an open category for still images by any microscopist, and a video category for clips up to 15 seconds. Judges choose first ($500), second ($300), and third ($100) prizes in each category, and the community votes for a people’s choice award. Up to three images may be submitted per year, and the images do not have to share a category. Because the open category welcomes any microscopist, it is a realistic first target for a photographer who has recently started shooting through a scope.
BINA Light Microscopy Image Contest
BioImaging North America’s 2026 contest was open to bioimaging scientists, and monetary prizes were limited to BINA members based in Canada, the USA, or Mexico. It is a good example of a contest where membership, not skill, decides whether you are eligible for money. If you work in an imaging core facility, it is worth joining; if you do not, move on.
Close-up Photographer of the Year
Based in the United Kingdom, CUPOTY is a macro and close-up competition rather than a pure microscopy one, but it matters to this audience. The 2026 rules show paid entries closing in mid-July, adult fees from £22 to £44 depending on the number of images, and a Young CUPOTY section for entrants aged 17 and under at £5 for up to 15 images. Post-processing is allowed if it does not deceive the viewer or misrepresent nature, except in the Studio Art category, where any creative technique is permitted.
Institutional contests
University and institute competitions appear every year, but most are closed to outsiders. The Madrid-based ICMM’s Matterimages contest for materials-science images, for example, was limited to institute staff and paid training-travel funding of up to 1,000 euros for first prize. Imperial College London’s NHLI Image Competition included a microscopic-images category for NHLI staff and students, with winning images framed and displayed in institute buildings. Unless you belong to the organization, treat these as inspiration for what a strong caption and scientific context look like.
Who is eligible, and what the files must look like
Eligibility is where most microscopy entries fail before a judge sees them. Using Nikon’s rules as the benchmark:
Entrants must be at least 18, or older if that is the legal age of majority where they live.
The image must be made with a light microscope.
Files must be digital .jpeg, .png, .psd, or .tiff.
You provide equipment details and a description of the image.
AI-generated images are ineligible, as are images already recognized in an active or ongoing photomicrography competition.
That last rule has a practical consequence. If an image wins a smaller contest while a larger one is still open, it may no longer qualify for the larger one. Sequence your entries so the biggest prize gets first claim, and keep a simple log of what is entered where. Our guide to photo contest eligibility checks covers the broader set of disqualification traps, from age limits to prior publication.
How to submit, and what rights you grant
Nikon takes up to three images through an online form that asks for registration information, equipment details, and image descriptions. You must own the rights and have the authority to submit. Winners keep copyright but grant Nikon a perpetual, worldwide, royalty-free promotional licence, per the rules page.
CUPOTY’s terms differ in length: entrants retain full copyright and grant the competition, its sponsors, and supporters a non-exclusive, irrevocable, royalty-free licence to use winning, Top 100, or shortlisted images for competition-related purposes for five years after the winners are announced.
The Microscopy Today awards add another wrinkle: if someone else owns the copyright to the image, such as a lab or employer, the entrant needs permission, and the contest asks for a signed permission form. If you shoot in a university or company lab, settle this before you submit, not after you win.
Before you click send, ask:
Do I own the image, or does my lab or employer?
How long does the licence last, and does it cover commercial use?
Is the licence exclusive? Non-exclusive terms leave you free to sell prints or license the image elsewhere.
May I enter the same file in other contests at the same time?
Taking a photograph through a microscope that meets the rules
The rules make one thing plain: the entrant must capture the image personally with a light microscope, and Nikon may ask for the original file for verification. That shapes your workflow.
Keep your raw material. Save the original captures, stack source frames, and any acquisition metadata. Verification requests arrive after you have forgotten which settings you used.
Record the optics. Objective, magnification, contrast technique (brightfield, darkfield, polarized light, differential interference contrast, fluorescence), and camera. Entry forms ask for it, and judges read it.
Use stacking and stitching openly. Focus stacking and tiling are ordinary practice in photomicrography, and a 2018 report on Nikon’s winners is not needed to know it: just state the method in your description. Hiding it is what causes trouble.
Edit conservatively. Adjust exposure, white balance, and contrast the way you would in any scientific publication. Heavy manipulation that changes the structure is a quick route to disqualification in most competitions outside studio-art categories.

What judges look for
The criteria repeat across contests, with slightly different wording. Nikon’s judges assess creativity and originality, informational content, technical proficiency, and artistic and visual impact. Evident’s jury looks at artistic and visual aspects, scientific impact, and microscope proficiency, in a contest that celebrates art, science, and technical mastery.
In practice that means a winning entry usually does four things:
Shows something unfamiliar. A well-lit diatom is lovely; a rarely imaged structure or behavior is memorable.
Explains itself. A two-sentence description naming the specimen, the technique, and why it matters gives the jury a reason to rank you higher.
Is technically clean. Even illumination, controlled noise, accurate color, sharp where it counts.
Holds the eye. Composition still matters. Leave space, use the diagonal, let color carry the structure.
A useful exercise is to study last year’s winners and write down, for each, what it shows, how it was made, and why it works. After ten images a pattern appears.
Our perspective
We do not run contests. We research them, and the pattern we see after years of tracking international competitions is that microscopy rewards patience more than any other genre. The photographers who place repeatedly are rarely the ones with the most expensive instrument; they are the ones who treat a specimen like a portrait subject, returning to it, changing the lighting, and writing a caption that a curator or editor can use.
We also notice that microscopy contests are quietly under-entered. Search interest is modest, many entrants are scientists who have never considered the photographic side, and a photographer who brings composition and a disciplined eye to a lab image has a genuine advantage. The risk is entering blindly: eligibility rules vary by membership and region, and licence clauses vary by organizer. A calm half hour with the rules saves a wasted entry.
Our advice is to build a small portfolio of three to six images, enter the open competitions first, and treat every result, including a shortlist, as editorial visibility you can cite in your portfolio.

Keeping track of deadlines without the spreadsheet
Microscopy deadlines scatter across the year: some close in winter, some in summer, some in spring. Tracking them by hand means revisiting a dozen sites. Our PhotoContestsClub directory gathers more than 320 active international contests on one chronological page, including over 100 free to enter, with deadlines, fees, prizes, and genres. It costs €6 per month or €40 per year, and a free trial is available. If you shoot macro, science, and nature together, it lets you plan one season of entries around all of them rather than discovering a closed contest after the fact.
A simple entry plan for your first season
Pick two or three contests whose eligibility you clearly meet. Start with the free, open ones.
Select your best three images per contest and match each to its categories.
Write the description first. Specimen, technique, equipment, and why it is interesting, in plain language.
Check the licence and any permission needed from a lab or employer.
Submit early, not on deadline day, and keep your originals.
Log everything: file names, contests, dates, outcomes.
The same discipline works if you want to widen the net beyond microscopy, for instance with our list of amateur photo contests.
FAQ
Are there free microscopy photo contests?
Yes. Nikon’s photomicrography competition is free to enter according to its official rules. Other contests charge fees or limit entry to members, so read each page before preparing files.
Do I need a research microscope to enter?
You need a light microscope you can capture images through, and Nikon requires that you capture the image yourself. Instrument class matters less than technique and the idea behind the image, though some contests judge microscope proficiency explicitly.
Can I enter the same image in several contests?
Only if the rules allow it. Nikon, for example, rejects images already recognized in an active or ongoing photomicrography competition, so enter the contest you most want to win first.
Who owns the copyright if I win?
In the contests cited here you keep copyright, but you grant the organizer a promotional licence. Nikon’s is perpetual and worldwide; CUPOTY’s runs five years from the announcement of winners. Read the licence before you submit.
When do microscopy contests open and close?
They follow annual cycles, with different seasons for each organizer. Nikon’s cycle opens in summer and closes in spring, while others close in winter or summer. Confirm the current dates on the official page of each contest.
