These are determined either by tapping into an OS X application such as “Subdivide”, or tapping into an iOS app such as “Pro Metronome” on an Apple iPad, or alternatively calculated from the time taken for a given number of beats — in either case looking for a section without too much rubato, and typically not the very beginning of a movement.
Unless noted otherwise, durations are without eventual applause, and possibly corrected for excess blank trails at the end (or at the beginning) — they may therefore deviate from the actual (CD or download) track duration.
Most metronome & timing tables are generated as MS Excel spreadsheets that I export to PDF and then convert into a suitable graphics format (typically PNG) — how I do the color coding in MS Excel is far too quirky to be explained here.
CD & Booklet Front Pages — Updated
For ripped CDs from my collection, CD & booklet front pages are typically scanned and processed through Adobe Photoshop using the following procedure:
- scan at 1200 dpi (HP OfficeJet Pro 276dw MFP)
- straightening & cropping
- possible removing spots etc. / image repair
- Gaussian blurring (“Filter” -> “Blur” -> “Gaussian Blur”, just enough to remove print pattern, typically with a radius of 3 – 4 pixels), possibly followed by selective sharpening (“Filter” -> “Sharpen” -> “Sharpen Edges”)
- the Color gamut is expanded using “Image” -> “Image adjustments” -> “Curves”
- scaling down to 150 dpi (final size around 700 x 700 pixels),
- saving in high-quality JPEG format
