Aperture, Focus, and Lighting: Scanning Vinyl Covers for CD Art

A well-made CD transfer deserves artwork that feels equally considered. A record sleeve can carry the character of an album through its typography, colour, photography and ageing, but a careless scan may flatten those qualities into a dull, blurred image. Getting the cover right is a practical part of preserving the music.

Scanning album artwork is different from photographing it with a phone. A flatbed scanner gives consistent geometry, even focus and useful control over resolution, while careful lighting helps when you need to capture a gatefold sleeve, poster or textured insert that will not fit neatly on the glass. The aim is a clean digital master that can later be resized for a CD booklet, jewel-case insert or digital archive.

This guide looks at aperture, focus, exposure and colour management in plain terms, with the needs of Australian record collectors in mind. Whether your collection came from a Melbourne market, a Sydney second-hand shop, a Brisbane garage sale or a family music room in regional Queensland, the same principle applies: preserve the sleeve as faithfully as practical before making a smaller copy for the disc.

Preparing Sleeves Before Digitising

Begin by examining the cover under neutral light. Look for fingerprints, loose dust, surface grime, creases and curled corners. A soft photographic brush or air blower can remove dry particles, but avoid household cleaning sprays and rough cloths. Glossy laminated sleeves can show every smear once scanned, and moisture may damage paper, inks or old adhesive.

Allow records and covers to adjust to the room before scanning them. This matters when bringing a collection home from a hot car in Adelaide or from a damp storage area near the Queensland coast. Sudden changes in temperature can encourage condensation, while high humidity may make paper feel slightly soft. Keep the sleeve flat and give it time to settle.

Remove records from the jacket before working with the artwork. A disc inside the sleeve adds weight, creates pressure against the paper and can worsen ring wear. If the cover has a fold-out design, scan each panel separately and leave a small overlap so the sections can be aligned later. Photographing or scanning a valuable original should be done with clean hands and a clear workspace.

Choosing Resolution And File Format

For most 12-inch LP covers, scan at 600 pixels per inch when the artwork will be edited, restored or printed at a useful size. A 300 ppi scan can be sufficient for a small CD insert, but 600 ppi gives extra room for cropping, removing borders and correcting perspective. Very high settings may produce large files without revealing more real detail, particularly when the original printing is soft or heavily textured.

Use the scanner’s optical resolution rather than an advertised interpolated figure. Optical resolution describes the detail captured by the scanner hardware; interpolation enlarges existing information. Save a master as TIFF or another lossless format, preferably in 16-bit colour when your software and scanner support it. Make JPEG copies only for delivery, web pages or compact working files.

For CD art, scan the whole front cover or sleeve panel first. Do not crop tightly during capture. Extra edges provide room to straighten a tilted image, remove a scanner border and create consistent margins across a set of albums. Keep a plainly named archive copy, such as Artist_Title_front_600dpi.tif, before making an edited version.

The site’s DIY transfer guidance sits within the same practical spirit: preserve the source carefully, keep a high-quality working file and create convenient copies only after the original has been secured.

Aperture, Focus And Exposure

A flatbed scanner does not have a user-adjustable camera aperture in the usual sense. Its light source and sensor move across the artwork at a fixed optical arrangement. For that reason, aperture becomes relevant when you photograph oversized sleeves, three-dimensional packaging, framed artwork or inserts that cannot lie flat. Understanding it helps you make sensible choices with a camera.

A wide aperture, represented by a small f-number such as f/2.8, admits more light but creates a shallow depth of field. That can leave one edge of a slightly bowed sleeve sharp while another edge is soft. A narrower aperture, such as f/8 or f/11, gives more depth of field and is usually safer for flat-lay artwork, although very narrow settings can introduce diffraction and reduce fine detail.

Use manual focus when photographing covers. Focus on the artwork’s surface rather than on a nearby table or the front edge of the camera. If the sleeve is flat, focus around its centre and check all four corners at full magnification. A stable tripod, parallel camera alignment and a remote shutter release are more valuable than simply increasing sharpness in software.

Exposure should retain detail in pale paper and dark photographic areas. Use the camera histogram and avoid clipped highlights, especially on white borders or metallic lettering. Two diffuse lights placed at equal angles can provide even illumination, while polarising filters may reduce reflections from glossy lamination. Keep lights away from direct contact with the sleeve and avoid hot lamps that could warm or warp old paper.

Lighting And Colour Accuracy

Scanner lids generally provide even illumination, which is why a flatbed is the first choice for most LP jackets. If the lid cannot close because of a gatefold or thick booklet, cover the setup with a clean, opaque sheet to block room light. Stray daylight from a window can create uneven colour, particularly during a long scan on a cloudy afternoon in Hobart or a bright summer morning in Perth.

Set the scanner to colour mode even when the sleeve appears black and white. Warm paper, faded ink and subtle grey printing are part of the object’s history. A neutral grey card or colour target can help establish a reference, though it must be kept outside the final artwork area or cropped afterwards. Calibrate the monitor if possible, since an overly bright or heavily saturated display can lead to poor editing decisions.

Avoid automatic corrections until you have saved the untouched scan. Auto contrast, sharpening and dust removal can alter fine type, halftone dots and deliberate ageing. Make gentle adjustments on a duplicate file: correct the white balance, neutralise an obvious colour cast, then adjust levels rather than pushing saturation. Record whether the sleeve has been digitally cleaned so future viewers can distinguish restoration from the original condition.

When photographing artwork, use softboxes, diffused LED panels or indirect daylight rather than a bare flash. Reflections from laminated 1970s covers are especially distracting, and flash mounted close to the lens tends to create a bright hotspot. A pair of lights at matching brightness produces more reliable results than moving a single lamp around between shots.

Editing, Layout And CD Printing

After capture, straighten the image before cropping. Use the sleeve’s printed edges, lettering baselines or geometric borders as guides. Correct minor perspective carefully; aggressive transformation can stretch faces, circles and type. If a gatefold has been scanned in sections, align the panels using fixed details such as text, lines and repeated colour blocks.

Dust removal should be selective. Small white specks in an empty background can be safely retouched, but scratches, ring wear, writing and faded patches may be genuine evidence of the cover’s life. For a personal CD copy, a discreet clean-up may improve readability. For an archival version, keep the original scan untouched and save restoration work as a separate file.

CD artwork needs accurate dimensions as well as good resolution. A standard jewel-case front insert is smaller than a 12-inch sleeve, so reduce the image only after editing. Apply modest sharpening at the final output size, because sharpening a large master and then shrinking it can make edges look harsh. Print a test on ordinary paper to check trimming, margins and whether small catalogue text remains legible.

Some album covers have artwork that reaches the edge, while others depend on a deliberate white border. Do not assume every design should be filled to the printable area. Preserve the original proportions and make a note of any missing spine, inner sleeve or back-cover information. For personal collections, consistent file naming and folders by artist or label make the finished archive easier to browse than a collection of anonymous image files.

Practical Scanning Recommendations

A simple workflow keeps the creative decisions separate from the technical ones. Capture a complete, high-resolution master first, then make a working copy for cleaning, resizing and printing. This approach is particularly useful when replacing worn CD copies of records that are hard to find locally or costly to import into Australia.

• Clean the scanner glass and sleeve surface before every group of scans.
• Use 600 ppi for master artwork when storage space allows.
• Keep the camera or scanner perfectly parallel to the cover.
• Save an untouched TIFF before applying colour correction or retouching.
• Use diffuse, balanced lighting for glossy or oversized sleeves.
• Print a paper proof before committing artwork to a CD insert.

Keep storage in at least two locations, such as an external drive and a separate backup. A collection built over decades can disappear through one failed drive, accidental deletion or a damaged laptop. Include catalogue numbers, edition details and scan dates in filenames or a simple text record, especially when several Australian pressings have similar covers.

The latest site notes can be useful when checking related transfer and preservation topics, but the central habit remains straightforward: capture carefully, edit conservatively and keep the first scan safe. Good digital artwork should support the music rather than distract from it.

A few minutes spent levelling the cover, checking focus and balancing the light can transform the result. Start with one sleeve that matters to you, create a full-resolution master, and compare the printed proof with the original under neutral light. Once the workflow is reliable, work through the collection methodically and give each CD copy artwork that reflects the care invested in preserving its sound.
