The quick answer
Position the phone square to the artwork, illuminate the whole surface evenly and include all four edges in a reference frame. Check a center detail and the corners before moving anything. Make a faithful full-work photograph first, then separate detail images for texture, signatures or condition.
Choose a record of the work before a styled photograph
A portfolio image should let the viewer assess the artwork. A studio photograph may instead show the work, room and artist together. Make those different pictures intentionally. Do not use a dramatic room view as the only record of a painting whose colors and proportions matter.
List the required files before setting up: full work, one texture detail and a signature or condition view if relevant. Record the title and dimensions in your notes so they remain associated with the correct files during editing.
Align the phone with the work itself
The University of Iowa recommends even light and aligning a two-dimensional work with the camera frame; larger work can be photographed on a neutral wall. Smith College advises centering the camera at the artwork’s midpoint. Keep the phone’s image plane parallel to the surface, including any tilt in the work.
For a rectangular painting, compare opposite sides in your preview. If one side appears much shorter, adjust the camera position before cropping. Leave a small border in a reference image so you can verify the shape later. Avoid a very tight capture that conceals an accidentally missing corner.
Check the full surface for glare and uneven light
Iowa advises against the phone’s built-in flash for documenting artwork. If you use two lights, Smith College describes placing them to either side and adjusting their positions to avoid reflections. Its camera-specific aperture and lens settings are not universal phone settings.
Inspect several points rather than judging the center alone: top, bottom, both sides and a region with subtle color. A bright patch that moves when the light moves is a capture problem to solve before editing. On glossy or framed work, try another lighting position instead of making the whole image darker.
Do not unframe a fragile work or touch its surface just to remove glare. If you cannot make an acceptable record with a safe setup, use a specialist reproduction service or document the limitation alongside the image.
Use a consistent capture and review sequence
Full reference. Include the entire work and a narrow surrounding border. Keep this frame even if the final submission requires a closer crop.
Geometry check. Compare straight edges and corners in the saved file. Correct the physical setup if a large adjustment would be needed.
Detail check. Inspect a fine mark in the center and near a corner. A sharp center alone is not enough for a faithful full-work reproduction.
Separate detail image. Photograph texture or a signature with its own framing. Keep its filename associated with the full-work image.
Edit to match the object, not a fashionable look
Compare the capture with the work in a stable viewing situation. Do not increase saturation simply because the phone display makes the picture feel subdued. If a color is important to an application or print, a casual screen comparison is not a substitute for a controlled color workflow.
Keep an untouched capture and a delivery copy. Record any perspective correction or significant color adjustment. Cropping a border is different from removing a mark that belongs to the work. For a submission, follow its actual file and framing requirements rather than assuming every portfolio wants the same format.
Common questions
Is this the same as scanning an old printed photograph?
No. A large painting or drawing requires attention to its plane, surface, illumination and faithful appearance. A detail view may need different light from the full-work record.
Can I use Portrait mode to blur the wall?
For a reproduction, start with a normal photograph that preserves the work’s boundaries. Make a separate styled image if you want a more decorative presentation.
