Photographing your painting
Photo quality changes everything: to track a painting's progress, archive it, share it or compare it to its reference, a bad photo gives bad information. Glare, perspective, distorted colours, crushed values… all faults that betray the real work. The good news: a few simple principles are enough to get a faithful photo, even with a phone.
Light: diffuse and even
Light is the number-one factor. Look for diffuse natural light: near a window without direct sun, or outdoors on an overcast day. Direct sun creates shiny reflections on the paint (especially oil or satin acrylic) and hard shadows that distort the values. The ideal is soft, even light that lights the whole surface the same way.
For even more even lighting, place two identical sources on either side of the canvas, at 45°, at equal distance. This symmetrical setup removes cast shadows and spreads the light uniformly. Avoid mixing sources (a yellow lamp plus a bluish window): the different colour temperatures create casts that are impossible to correct cleanly.
The angle: square to the canvas
Place the camera parallel to the canvas, the lens centred on the middle of the painting. A tilted or offset camera introduces perspective: the canvas becomes trapezoidal, one side larger than the other. For a rectangle to stay a rectangle, the camera must look at the surface perpendicularly — not from above, not at an angle.
A tripod helps enormously: it guarantees stability, sharpness and a repeatable framing. Step back a little and zoom rather than putting the lens right up close: wide-angle lenses, very near, distort the edges (a «bulging» effect). Backing up and zooming slightly flattens the perspective and restores the true proportions.
No flash, no glare
Never use the built-in flash. It crushes the values, creates a bright spot in the centre and casts a cold, flat light that kills the relief of the paint. Use the ambient light described above. If reflections persist anyway — common on varnish and thick impasto — tilt the canvas very slightly or change your position until the shiny area disappears, without introducing perspective.
On very glossy surfaces, a polarising filter (on camera or lens) strongly reduces reflections. Failing that, the diffuse light of an overcast day remains the best ally: it produces very few specular reflections, unlike a point source.
Framing, settings and consistency
Frame tight on the canvas alone, without the stretcher edge, the easel or the wall — you'll crop precisely afterwards. Set the exposure so you burn out neither the whites nor the blacks: on a phone, tap the mid-tone area of the screen to lock exposure, and lower it slightly if the highlights are «blown». For colour, photographing a grey card or a plain white sheet in the frame gives a reference point to correct the white balance later.
Finally, to track a canvas from session to session, consistency is key: same camera, same spot, same light, same distance for every shot. Two photos taken under identical conditions are comparable; two photos taken any old way are not. It is this regularity that turns a series of snapshots into a true visual record of progress.
Correcting the photo after shooting
Even in good conditions, a light edit almost always improves the result. Three adjustments are enough. Cropping and straightening: cut away everything that isn't the canvas and correct any residual perspective (most phones offer a «perspective» or «keystone» tool). White balance: if you photographed a white sheet in the frame, set the white point on it to recover neutral colours. Exposure and contrast: adjust so the lightest white of the canvas is white and the darkest black is black, without crushing the detail.
The goal is not to «beautify» the canvas but to render it faithfully: the corrected photo should look like the painting as it is under good light. Resist the temptation to saturate colours or push contrast beyond reality; an over-edited photo becomes a lie that will mislead you when comparing with your reference or when printing.
Which gear, and for what use?
For everyday use — tracking progress, sharing on social media, comparing to a reference — a recent phone is more than enough, provided you respect light and angle. Its limits show mostly in low light (digital noise) and on very large formats. A tabletop tripod and a small remote (or the self-timer) eliminate camera shake, which is the most common cause of failed sharpness.
For archiving, selling prints or submitting to a jury, the bar rises: you aim for a much sharper image with controlled colour, often achieved with a dedicated interchangeable-lens camera, two equal light sources and a colour chart. But don't let the search for perfect gear paralyse you: a phone photo taken in soft light, well framed and corrected, is a thousand times better than a «pro» shot rushed under a fluorescent tube.
The checklist before you shoot
To turn these principles into reflex, keep a short list in mind before each shot. Is the light soft and even, with no glare or hard shadow on the canvas? Is the camera square to the surface, centred, without tilt? Is the framing tight on the canvas alone? Does the exposure preserve the whites and blacks without burning them out? Have I stabilised the camera to avoid any blur? Five questions, ten seconds: that is the price of a usable photo on the first try.
This rigour pays off most over time. A canvas tracked over weeks, photographed each session under the same conditions, produces a series of genuinely comparable images — a true visual journal where you can measure progress, revisit a decision, or spot the moment a colour went astray. Photo quality is not a technical detail: it is what makes tracking your work reliable.
Practical tips
- → Diffuse natural light, never flash: direct sun and flash crush the values and create glare.
- → Camera square to the canvas and centred: back up and zoom slightly to avoid distortion.
- → Same camera, same angle, same light every session: comparison only makes sense if the conditions are stable.
