How We Document Paintings for Submission: A Studio Guide

There’s a particular silence that settles in the studio when the last brushstroke lands. You step back, exhale, and let yourself believe the work is done. Then reality taps you on the shoulder: a juried show deadline is looming, and now you have to photograph this canvas so it reads true on a curator’s laptop in a room you’ll never see. For pieces from The Dark Don’t Hide It, where deep blacks and visceral reds carry the emotional weight, getting that photograph right isn’t a chore tacked onto the end of painting—it’s a separate discipline entirely. This is the workflow we’ve built to make sure what a selection panel sees is what actually hangs on the wall.

Why Good Documentation Makes or Breaks Your Submission

Selection panels don’t see your painting first. They see a JPEG on a calibrated monitor, often alongside three hundred other JPEGs, and they make snap judgements about whether your work belongs in their exhibition. If the file is muddy, skewed, or riddled with glare, the most arresting canvas in London won’t get past the first cut. We learned this the hard way with early entries from The Dark Don’t Hide It—paintings we knew held real tension were rejected purely because our photographs flattened the shadows into a single block of noise. The Royal Academy Summer Exhibition now runs a fully digital pre-selection round, meaning your image has to convince a complete stranger that the physical object deserves wall space. That’s a high bar, and it resets every single year. Jurors scroll fast, and the consensus from artists who’ve sat on panels is brutal: you have roughly three seconds before someone moves on. In that window, your photograph needs to communicate scale, surface quality, and colour relationships without any visual friction. A handheld snap taken under a warm ceiling bulb broadcasts a clear message: this artist doesn’t take the submission process seriously.

Our Pre-Shoot Checklist: Canvas, Light, and Space

Rushing into a shoot without checking the painting itself is the most common mistake we see in open-call forums. Even a flawless lighting setup can’t rescue a canvas that’s still off-gassing or carrying a fingerprint across a dark passage. We run through the same sequence every time, and it starts with the object, not the camera. We wait until the painting is fully dry and any varnish has cured completely—this can mean a week or more for the oil-rich layers in The Dark Don’t Hide It. Before the canvas goes near the backdrop, we inspect it under raking light to catch dust, stray bristles, or subtle scuffs. A large soft goat-hair brush and a hand-blower take care of surface debris. If the varnish is still tacky, we reschedule. Impatience here creates glare spots that no amount of post-processing can fix.

Our studio gets good northern light through a tall sash window, and on overcast mornings that diffuse grey sky is hard to beat. The catch is consistency. A cloud passes, and suddenly your exposure shifts by half a stop. For submission work, where we might need to match colour across multiple paintings, we rely on a pair of Rotolight LED panels. They’re flicker-free, colour-accurate, and let us lock in a setup we can replicate exactly six months later. We position them at 45 degrees to the canvas surface, equidistant, with diffusion domes attached to kill any hot spots. We shoot against a neutral grey backdrop—a wide roll of seamless paper from Cass Art in London. Grey doesn’t throw colour casts back onto the painting the way a white wall can. The canvas sits on a sturdy studio easel adjusted so the centre of the painting is exactly level with the lens. We use a spirit level on both the easel and the camera. Eyeballing it isn’t enough; even a degree of tilt introduces keystoning that will cost you in the crop.

Camera Settings and Colour Accuracy for Painters

This is where we stop guessing. Phone cameras and automatic modes make decisions based on algorithms built for skin tones and landscapes—they have no idea what to do with a cadmium red glazed over an umber ground. Our current setup is built around a Sony A7 III with a 90mm macro lens, and we treat the capture process as a technical exercise, not a creative one. We shoot at f/8 or f/11—sharp enough to hold texture across the whole canvas without dipping into diffraction territory. ISO stays locked at 100. Shutter speed varies with the light, but we’re usually around 1/10 to 1/20 of a second on a tripod, triggered remotely to eliminate any vibration. The 90mm focal length gives us a flat field with minimal distortion, which matters enormously when you’re trying to keep stretcher bars square to the frame edges.

We tether the camera directly into Capture One on a laptop, which lets us check focus and colour on a proper screen seconds after the shutter fires. The difference between a sharp image and one that’s slightly soft at 100% zoom is invisible on a three-inch camera LCD. Tethering also means we can overlay a grid to confirm alignment and compare successive shots side by side before we break the setup down. The reds and deep blacks central to The Dark Don’t Hide It are unforgiving. A slight magenta shift in the shadows, and the whole emotional register of a piece tips into something unintended. We use a Datacolor SpyderCHECKR in the first frame of every shoot—placed in front of the canvas, under the same light—to generate a custom colour profile. We also calibrate our monitors with a SpyderX every two weeks. When a juror opens our file, we know the colour they’re seeing is as close to the painting as a screen can deliver.

Framing, Cropping, and the ‘Straight-On’ Rule

Every major UK portrait prize—including the Herbert Smith Freehills Portrait Award—publishes guidelines that effectively demand a dead-on, square-to-the-sensor photograph with no background clutter. We follow those guidelines as a baseline for every submission, regardless of the competition. Keystoning happens when the camera sensor isn’t parallel to the canvas, causing vertical lines to converge or diverge. The solution is mechanical: measure from the lens to each corner of the canvas. When all four distances match, the sensor is parallel. We then frame the painting so it fills roughly 80% of the viewfinder, leaving a small border of the grey backdrop. That border proves we haven’t cropped into the painted surface, and it gives us room to fine-tune alignment in post. The frame should contain the full canvas face—edge to edge—plus a narrow, even border of backdrop. We exclude easel clamps, skirting boards, light stands, and anything else that identifies a studio rather than a gallery. If the painting is framed, we shoot it framed, but only if the frame is clean and the glazing is removed. Glass is a nightmare for reflections.

Post-Processing and File Prep for Online Portals

We keep editing to a minimum. The goal is to make the file match the painting, not to produce a more flattering version of it. Over-processed submission images fall apart when the physical work arrives and doesn’t deliver the same pop—if you get caught, you burn trust with curators. We import into Lightroom after the Capture One colour work, but only for final global adjustments. A slight contrast curve to match the perceptual depth of the paint surface, a modest clarity bump (never more than +10) to preserve brush texture, and occasionally a luminance adjustment on a single colour channel if the camera sensor has misread a pigment. We never clone out texture, dust, or canvas weave. If a juror zooms in and sees digital smoothing, your file looks like a reproduction, not a painting.

Most UK submission platforms—Zealous, OESS, and bespoke gallery portals—ask for sRGB JPEGs with a long edge between 2000 and 4000 pixels and a file size under 5MB. We export at 3000 pixels on the long edge, sRGB colour space, quality around 85%. That gives us a clean, detailed file that uploads quickly and displays consistently across browsers. And while you’ll still hear people insist on 300dpi for digital submissions, that number is meaningless on a screen—DPI is a print instruction, not a pixel dimension. We set it to 300 in the metadata because some portals expect it, but we don’t let it drive the export.

Archiving and Reusing Submission Assets

A good submission photograph is an asset that pays out repeatedly. We don’t re-shoot a painting unless it’s been reworked or re-varnished. The files we generate for competition entries also feed our website, social media, and print-on-demand tests. We name every submission file using a consistent format: Boilini_Title_Year.jpg. No spaces, no special characters, no version numbers that leave you guessing which file was actually sent. For a painting called “Vigil” completed in 2024, the file reads Boilini_Vigil_2024.jpg. This makes searching across drives and cloud folders trivial, and it looks professional when a portal displays the filename to jurors. From one tethered session we generate the submission JPEG, a full-resolution TIFF for our archive, a web-optimised version for laurenboilini.net, and a 1:1 crop for Instagram. Organisations like The New English Art Club and ING Discerning Eye run annual open calls, and having a clean archive means we can apply to several in an afternoon without touching the camera.

Frequently Asked Questions

Here are answers to the questions we hear most often from painters preparing their first digital submission.

• Can I use a smartphone instead of a DSLR? Yes, if you control the light and stabilise the phone. A recent iPhone on a tripod, with natural northern light and an app that locks exposure and white balance, can produce acceptable results. The limitations show up in colour accuracy and texture detail—our tethered workflow gives us confidence we’re not leaving those to chance.
• How do I stop glare on glossy varnish? Position your lights at 45 degrees to the canvas surface and use diffusion panels or softboxes. If you’re using natural light, wait for an overcast day or hang a sheer white sheet across the window. Polarising filters can help, but they may desaturate colour if not used carefully.
• What’s the biggest mistake first-time submitters make? Rushing the photograph because they’re exhausted from finishing the painting. They shoot under warm domestic bulbs, handheld, with the painting still on the kitchen table. The result is a yellow-tinted, soft-focus file. Treat the documentation as a separate session, with fresh eyes and a checklist.
• Do I need to remove the canvas from its frame? Not necessarily. If the frame is part of the work’s presentation, photograph it framed—but remove any glass or glazing. If the frame is purely protective, shoot the unframed canvas edge-to-edge so jurors see the full painted surface.
• How often should I recalibrate my monitor? We recalibrate every two weeks with a Datacolor SpyderX. Ambient light changes with the seasons, and monitors drift over time. If you’re in the middle of a submission cycle, calibrate before you start editing and again before the final export.

Documenting paintings for submission isn’t a detour from the creative work—it’s the final, necessary act of presentation that decides whether that work gets seen. For a series like The Dark Don’t Hide It, where the paint surface carries as much meaning as the image, a faithful photograph is an extension of the studio practice. We’ve built our workflow around that principle: respect the painting enough to show it truthfully, and give the people behind the screen every reason to say yes.
