Additional Information[edit]
en: Longines pocket watch, model 4 Grand Prix
- Manual winding
- Silver casing (800/1000)
- Rear view, clockwork exposed, visible wear marks
- Case diameter (width): 47 mm; height including crown: 61 mm.
- Manufactured in Swítzerland
- According to the serial number (S/N) 1999795 this pocket watch was produced in approx. mid 1907.[1] Production commences with S/N 1,950,000 (approx.) in 1907 and subsequently with 2,100,000 (approx.) in 1908.
- Presumably ersatz hands (both hour and minute hands).
- Very surprising fact: the caliber (i.e. the actual inner workings of a watch) is a true mirror image of similar Longines 4 Grand Prix pocket watches (yet correct writing direction in both cases).
- This image was taken at an acquainted collector's residence in Germany. It is in dire need of a thorough re-oiling.
- See below for technical details concerning the "making of" this image.

Technical Details / Making of this Image[edit]
- Preamble: This image is not a focus stack, but is instead composed of 4 images taken at identical focus position by the proprietary Sony Alpha 7RIII PixelShift function.
- Sony lens FE 90mm F2.8 Macro G OSS, magnification ratio 1:3.2
- Shutter speed 1/40s, aperture 11, 16-bit RAW (.ARW), bias(=exp.comp.) -0.7, WB=7000K
- [1.] Sony Alpha 7RIII PixelShift function + selftimer: 4 RAW images shifted by 1 pixel (initial pos., up, right, down).
- [2.] Sony ImageViewer: processed these 4 pixel-shifted RAW images into one TIFF/16 bit file.
- [3.] Photoshop: Photoshop: (a) converted to smartfilter, applied camera RAW filter (b) applied Preset 002 (Presence+Sharp+NoiseRed) (c) expos.+1.00 (d) square crop (e) removed remaining dust and sensor specks (f) exported as JPG/max quality level.
- Result: improved colour rendering and slightly enhanced resolution due to above described quadruple imaging (via Sony Pixelshift function).

Ephemeral Glory 02: POTD on Wed., 2019-08-29: this image was featured as "Image du jour / Picture of the Day" on the main page of the French Wikipedia (scroll to Image labellisée du jour).

As to now the following wiki code for the Ukrainian link "{{w|uk:wikipedia:Шаблон%3APotd/2020-05#9|"POTD / Picture of the Day 2020-05-09"}}" stubbornly refuses to function. I'll perseveringly try to remedy this sometime.
