Identifying your artwork · Photo-based identification
Identify artwork from a photo
You can identify a lot about an artwork from photographs, provided you take the right ones: the whole front, the signature, the back, the edges and a close-up of the surface. Reverse image search finds famous or widely reproduced works; for everything else, the photos are evidence to be read for medium, period, school and maker.
What can a photo of an artwork actually show?
A good set of photographs shows the composition, the surface texture, the signature, the construction of the back and most labels and inscriptions. It cannot show the chemistry of the paint, what lies under the surface, or how the object feels and weighs.
Composition and subject
Enough to recognize a known image, place the subject in a genre (portrait, marine, still life, landscape) and spot dating details such as costume, architecture or transport.
Surface and technique
A close-up in raking light shows brushstrokes, impasto, palette-knife work, pencil underdrawing showing through watercolor, or the regular dot screen of a printed reproduction.
Signature and inscriptions
A sharp close-up lets you transcribe letters, dates and monograms that are unreadable in a full view, and shows whether the signature sits in or on the paint.
Verso construction
The back shows the support (canvas, panel, board, paper), the stretcher or strainer, nails, tacks or staples, and every label, stamp and handwritten note.
Edges and corners
Tacking margins on a canvas, the bevel of a panel or the deckle edge of paper show whether the work has been cut down, relined or remounted.
Scale
A tape measure in one shot records the size, which matters for both identification and market estimates: artists' standard formats and price levels depend on it.
How do you identify artwork from a photo, step by step?
Take a complete, well-lit set of photographs first, try image search for known works, then read the photographs as evidence: medium, period, signature, back, and finally candidate makers.
Take the core set of photos
Front, straight on and filling the frame; signature close-up; the whole back; each label close up; one surface detail in raking light; one shot with a tape measure. Use daylight from a window and avoid flash, which flares on varnish and glass.
Remove reflections and distortion
Keep the camera parallel to the artwork to avoid keystoning. For glazed works, shoot at a slight angle or turn off room lights so you do not photograph yourself in the glass.
Run a reverse image search
Google Lens, Bing Visual Search and TinEye are good at finding famous paintings, posters and mass-market prints. A match with a museum painting usually means you have a reproduction, not the original.
Read the medium and support
From the surface close-up and the back, decide whether the work is an oil, acrylic, watercolor, gouache, pastel, drawing or print, and on what support. This shapes every later search.
Transcribe the signature and labels
Write out every word, number and stamp visible in your photos, including supplier stamps on the canvas and pencil notes on the stretcher.
Place it in time and place
Use style, subject, materials and labels to propose a period and school. Compare with museum collections online, which you can filter by date, medium and country.
Search for the maker
Search the signature readings in artist dictionaries, filtered by the period and school you proposed. Compare signed works by each candidate with your photos.
Which photos make the difference?
In practice, one well-chosen photograph often unlocks an identification that the front view alone could not.
The raking-light close-up
A "painting" that shows perfect detail but no brushstroke relief in raking light, with a dot pattern under magnification, is an offset print. That single photo saves hours of artist research.
The back of a canvas
A Roberson stamp (the London artists' colorman at 99 Long Acre) on the canvas of a small oil places it in a British context and suggests nineteenth or early twentieth century, which narrows a signature search considerably.
A gallery label
A label from a New York gallery such as Macbeth or Knoedler, or a Paris dealer such as Durand-Ruel, gives a name to research and a stock or exhibition number that may still be traceable in archives.
The tacking margin
Paint that continues over the folded edges of the canvas suggests the picture was painted before being stretched to its present size, or has been cut down from a larger work, both worth knowing.
A known composition
Reverse image search identifies a rural scene as a well-known painting by Jean-François Millet. The owner's version is then investigated as a copy or print, and the question becomes when and how it was made.
Why do photo identifications go wrong?
Poor photos hide evidence, and image-search matches are easy to over-interpret. Most errors fall into a few predictable categories.
Only photographing the front
The back is skipped in most first attempts, yet it holds labels, stamps and construction details that date the work.
Using flash
Flash flattens texture and creates glare that hides signatures. Diffuse daylight is almost always better.
Assuming an image-search match means you own the original
If your painting matches a museum masterpiece, the overwhelming likelihood is that it is a copy or reproduction, and the original is still in the museum.
Cropping out the edges
The edges of a canvas or sheet show trimming, relining and printing borders. Include them in at least one photo.
Filters and heavy editing
Phone beauty filters and aggressive sharpening alter color and invent detail. Use the default camera mode and keep originals.
How can Veriso help?
Veriso is built around photographs. Upload up to seven images (front, back, signature, labels and details) and it analyzes them together: the medium and technique visible in the surface, the subject and the period it suggests, the signature reading, and the text of labels and inscriptions on the verso. It also checks for visually similar works in museum and reference collections.
The report lists what each photo contributed and where the evidence is thin, so you know which extra photograph, measurement or document would most improve the identification.
What is Veriso?
Veriso is an artwork investigation tool: it analyzes photographs of a painting or other artwork alongside the evidence that identifies it — subject, medium, technique, likely period and school, signatures, and verso labels — and sets out which attributions that evidence supports.
Veriso's findings are research, not a certificate: it does not authenticate artworks or replace a formal appraisal, and its market estimates are indicative ranges based on comparable sales. How Veriso works
Frequently asked questions
Can Google Lens identify a painting?
It is good at finding famous paintings and widely sold reproductions, because those images are all over the web. It rarely identifies unique works by lesser-known artists, which is most of what people own.
How many photos do I need to identify an artwork?
Five or six is a good set: front, signature, back, each label, a surface detail and a shot with a tape measure. More photos help only if they show something new.
Can a photo tell an original painting from a print?
Usually. A close-up in raking light shows brushstroke relief, and a macro photo shows whether there is a regular printing dot pattern. Some high-quality giclée prints with added varnish need an in-person look.
What if the painting is behind glass?
Photograph it at a slight angle with room lights off, or use a polarising filter if you have one. If it is safe to unframe, a photo without glass is far better, but do not force old frames or tapes.
Can a photo be used to authenticate an artwork?
Photos support research, not authentication. Recognized experts and catalogue raisonné committees normally require the physical work, documentation and sometimes scientific analysis.
