Artists have benefited immensely from the internet, as it allows them to showcase and sell their work to a vast audience. Digitizing artwork is a crucial skill for artists who want to sell their work online. There are two main ways to digitize artwork: scanning and photographing. Scanning is a more straightforward process, but it may not capture the depth and texture of a painting accurately. Photography, on the other hand, offers more control over lighting and composition but requires additional equipment like a camera and tripod. Editing software like Photoshop can enhance digital files, ensuring colours are accurate and making any necessary adjustments. Artists can then upload these digital files to print-on-demand sites, creating products like art prints, home furnishings, and more.

What You'll Learn
Scanning vs. photographing
There are two main ways to digitize a painting: scanning and photographing. Both methods have their own advantages and disadvantages, and the best choice depends on the specific needs and constraints of the user.
Scanning a painting is generally a more straightforward process that yields consistent results. It is easier to control the resolution of the final output, and there is less concern with color correction measures due to improper lighting. Scanners are also easily accessible, and there is no need for bulky camera equipment. However, scanning can be challenging for larger paintings, as most scanners have size limitations. Additionally, the texture of the painting can affect the scan quality, with grooves and textures causing light reflections that can be difficult to control. Scanners may also struggle to capture the subtle nuances and details of certain mediums, such as oil paintings.
Photographing a painting offers more flexibility in terms of capturing large or 3D artworks. It is also better equipped to handle textured pieces, as expert lighting techniques can be employed to assess shadows and eliminate shine. Photographers specializing in artwork reproduction can capture the fine details and colors of the painting, ensuring a high-quality reproduction. However, photographing artwork requires appropriate camera equipment, such as a tripod, camera, sharp lens, and lighting setup. It also demands a certain level of skill behind the camera to achieve proper color balance and high-resolution results. Post-processing work, such as color correction and white balance adjustments, is often necessary to ensure an accurate reproduction.
When deciding between scanning and photographing a painting, it is essential to consider the intended use of the digital file. If the goal is to create Giclee prints or reproductions, scanning is often preferred as it provides a clear and consistent digital copy. However, if the painting is particularly large or textured, photographing may be a better option, provided the photographer has the necessary expertise and equipment. Ultimately, both methods can produce high-quality results, but the specific characteristics of the painting and the desired outcome will influence the chosen approach.
To ensure the best possible outcome, it is recommended to inspect the digital file thoroughly before submitting it for printing. This includes checking for color accuracy, sharpness, and overall fidelity to the original painting. Seeking feedback from trusted individuals can also help determine if the digital file resembles a photocopy or a photograph of the artwork. By taking the time to prepare and inspect the digital file, artists can ensure that their paintings are accurately and attractively represented in their digital form.

Adjusting brightness and colour
Adjusting the brightness and colour of a digital image is a crucial step in enhancing your painting. This process can inject vibrancy and contrast into a dull or washed-out image, making it more eye-catching and visually appealing. Here is a detailed guide to help you adjust brightness and colour effectively:
Brightness Adjustments
Brightness adjustments can make your digital painting lighter or darker, depending on your preference. Here are some specific methods to adjust brightness:
- Using Brightness Tools: Most image editing software, such as Microsoft Paint, provides a Brightness adjustment tool. Go to the Adjustments menu, select Brightness/Contrast, and use the slider to adjust the brightness. Moving the slider to the right increases brightness, while moving it to the left decreases brightness.
- Adjusting RGB Channels: You can also adjust brightness by manipulating the RGB (Red, Green, and Blue) channels. Select the RGB channel in the Edit menu and adjust the brightness by dragging left or right. Moving the slider to the left makes the image brighter, while moving it to the right makes it darker.
- Utilising Curves Adjustment: The Curves adjustment tool, found in the Adjustments menu, allows for fine-tuned brightness adjustments. It lets you modify the luminosity and RGB colour curves of the image, giving you precise control over brightness and contrast.
- Playing with Opacity: If your image has multiple layers, try adjusting the opacity of a specific layer, such as the "Multiply" layer. Reducing opacity can brighten up parts of the painting that are too dark.
Colour Adjustments
Adjusting colours can add depth and emphasis to your digital painting. Here are some techniques to manipulate colour:
- Saturation Adjustment: Saturation adjustments can make colours more vivid and vibrant. Increasing saturation adds richness to colours, while decreasing it makes them appear washed out. This is a simple yet effective way to enhance the overall colour palette of your painting.
- Overlay Layer Blending: Overlay layer blending is a technique that makes light colours brighter and dark colours darker. It adds colour to previously colourless areas, reducing monotony and creating a more dynamic image.
- Colour Balance: Adjusting the colour balance involves changing the balance of each RGB colour. You can use sliders or input values to fine-tune the balance of colours, such as cyan and red, magenta and green, or yellow and blue.
- Multiply Technique: The multiply technique increases shadows in your image, drawing attention to the lighter areas and creating emphasis. It adds depth to your painting and can be especially useful when you want to highlight specific elements.
Remember, when adjusting brightness and colour, it's essential to strike a balance. Play around with the settings, use preview features, and compare your adjustments to the original image to ensure you achieve the desired effect without distorting the integrity of your artwork.

Using Photoshop
There are several ways to turn a painting into a digital file using Photoshop. Here is a step-by-step guide:
Scanning Your Painting
Firstly, you need to scan your painting. Make sure your scanning bed is clean to avoid including any dust or debris in your scan. Scanning your painting will give it a more professional look and allow you to create a high-quality image that can be scaled up for prints or products. Scan your artwork at 300 DPI or above to ensure a high-resolution digital image. 300 DPI is the standard resolution for printing, but scanning at 600 DPI will allow you to scale up your artwork without losing resolution.
Opening and Cropping in Photoshop
Once your painting is scanned, open the image in Photoshop. You can then crop the image to remove any unwanted areas and ensure only the painting and the background are visible. Use the Marquee tool (keyboard shortcut: M) to draw a box around the parts of the image you want to keep, then click Image → Crop to finalise the crop.
Duplicating the Background Layer
Your artwork will initially be set as the background layer. To unlock this layer and make it editable, double-click on the background layer. Then, press Ctrl+J on Windows or Command+J on Mac to duplicate the background layer.
Applying Filters
With your new editable layer, you can now apply various Photoshop filters to transform your painting. Go to Filter → Artistic → Paint Daubs to open the Paint Daubs dialog box, where you can adjust the Brush Size, Sharpness, and Strength to achieve your desired effect. Alternatively, you can use the Oil Paint filter (Filter → Stylize → Oil Paint) for thicker brushstrokes that mimic oil or acrylic paint.
Removing the Background
If you want to remove the background, you can do so by duplicating your original background again and dragging the new layer above your painting filter layer. On this new layer, apply Filter → Stylize → Find Edges. Change the blending mode on the Layer panel from Normal to Multiple to blend these new outlines into your painting, removing the background.
Saving Your Digital File
Once you're happy with your digital painting, go to the File menu and select Save As. You can then choose the file format you want to save your painting in. It's a good idea to develop a naming convention for your artwork files to keep them organised and easily searchable. For example, you can include the date (YYMMDD) and the name of the piece in the file name.

Printing requirements
Resolution and DPI:
The resolution of your digital file is crucial for maintaining the quality of your artwork when printing. The industry standard for printing on paper is a minimum of 300 DPI (dots per inch). Scanning your artwork at 300 DPI will allow you to print it up to the original size without losing resolution. If you want to scale up your artwork, you can increase the DPI accordingly. For example, scanning at 600 DPI will let you print up to twice the original size, while 1200 DPI will enable printing up to four times the original size. Higher DPI settings result in larger file sizes but offer more flexibility for printing on various products.
File Format:
When preparing your digital file for printing, it is recommended to use specific file formats for optimal results. TIFF (Tag Image File Format) is often the preferred choice as it retains image data integrity and supports CMYK color data for accurate printed colours. JPEG is another option but is better suited for RGB colour data used in digital formats. Additionally, JPEGs lose quality each time the file is opened and closed. However, JPEGs are useful when you need to reduce file size for online display or when creating files for web viewing, where the standard resolution is 72 DPI.
Colour Accuracy and Editing:
To ensure colour accuracy, use the CMYK (Cyan, Magenta, Yellow, Black) colour mode for printing, as it matches the inks used in colour printing. RGB (Red, Green, Blue) colour mode is typically used for screen viewing. You can edit your digital file using photo editing software like Photoshop to adjust colour variations, brightness, sharpness, and contrast. Play around with these settings to achieve the desired outcome and ensure your artwork looks professional and true to the original.
Printing Options:
Once your digital file is ready, you can choose to print it yourself or use a print-on-demand service or a professional printing company. If printing yourself, select the appropriate paper type, such as glossy or matte, and consider the type of ink to use—dye-based inks for vibrant colours and quick drying, or pigment-based inks for longevity. Always check with your chosen printer for specific file requirements, and proofread your artwork before submission to avoid any errors.
