Capturing Your Artwork: A Step-by-Step Guide to Professional Quality
In today’s digital world, the internet has become a prime platform for artists to share and promote their work. With a quality digital camera and basic editing software like GIMP, artists can create a portfolio and share their masterpieces through email and social media. However, capturing professional-quality images of artwork isn't as straightforward as it may seem. There’s a distinct art to photographing paintings in a way that preserves their color, texture, and true character—without glare or distortion. While you could always turn to a professional studio (some places even offer artwork scanning services), that can be costly—sometimes upwards of $250 for a single small piece. Instead, with a bit of practice and the right equipment, you can achieve comparable results at home.
Here, I’ll walk you through the essentials for photographing paintings, offering practical tips that help achieve a studio-quality finish. You’ll need a DSLR camera, and ideally, some basic photography knowledge.
Why Glare is an Issue and How to Eliminate It
One of the main challenges in photographing artwork is glare. Paintings, particularly those with impasto (thick paint applications), can reflect light unevenly, creating undesirable highlights that detract from the image. The best solution is a technique called "Cross Polarization" using a polarizing filter, which significantly reduces glare and preserves color accuracy.
Essential Equipment for Artwork Photography
DSLR Camera with a 50mm Lens
While various lenses can capture quality images, a fixed (non-zoom) 50mm lens is often preferred for its sharpness and accuracy, thanks to fewer internal elements. If a zoom lens is used, it’s best to set it at 50mm or higher; otherwise, lower focal lengths, like 35mm, can distort the image and affect the artwork’s proportions.
Polarizing Filter for the Lens
Attaching a linear polarizing filter to your lens is key. It’s important to avoid circular polarizing filters, which are more common and easier to use with autofocus. Linear filters do the job better for this purpose and will work fine with autofocus on modern cameras. Insist on this filter type at the camera store to ensure you get a glare-free image with richer, truer colors.
Lighting
Lighting is critical. Ideally, use two 500-watt tungsten bulbs (3200 Kelvin) positioned at a 45-degree angle from the artwork. You don’t necessarily need these exact lights, but the more powerful your light source, the more flexibility you have in distance, especially with larger paintings. With small works, a single light source can suffice, but be aware that the polarizing filter reduces the light reaching the camera sensor, so bright light is preferable for sharp images.
Tripod
Because this method requires longer exposure times due to the filter, a tripod is essential to keep the camera steady and eliminate any blur from hand movement.
Step-by-Step Photography Setup
Position the Lights: Place the two light sources at 45 degrees on either side of the painting to achieve even illumination. If you want to enhance the texture of brushstrokes, place both lights on the same side. For a smoother, flatter look, set the lights opposite each other at 45 degrees in an equilateral triangle formation with the camera at the peak.
For best results, photograph at night or in a room where you can control ambient light. Any stray, unpolarized light, such as sunlight, can reintroduce glare.
Set the Camera: Switch the camera to manual mode (M) and set an exposure of around five seconds with an aperture of f/10. Keep the ISO at the lowest possible setting, ideally 100, for optimal sharpness. If you’re shooting in JPEG format, set the White Balance to tungsten (or manually adjust it to 3200K if your camera allows). If shooting in RAW, this can be adjusted afterward during editing.
Adjust the Polarizing Filter: Look through the camera viewfinder and rotate the polarizing filter until the artwork appears slightly darker and any glare disappears. If it’s hard to see, move closer to adjust the filter, then step back to your original position.
Use the Self-Timer: To prevent blur, set the camera’s timer for a short delay (3-10 seconds), giving the camera a moment to stabilize before taking the shot. This prevents any shaking from pressing the shutter.
By following these steps carefully, you can capture beautifully clear and true-to-life photos of your artwork, with no need for heavy post-processing. A little practice, patience, and the right tools can make all the difference in presenting your work professionally online.
