Thanks, guys!
Of course, I do post-processing with my photos, but not much really.
When I shoot my family, I 99% use JPGs, unless I screwed up white balance or exposure.
First, for watch shots, the best is to use a longer lens - less distortion. With Fuji's 18-55 kit lens (ca 250€ used) + macro extension you can get great photos at 55mm. The details and resolution are good enough. But, I think a manual macro lens like Laowa 65mm is better.
With my watch photos, my process in Capture One Express (free for Fuji X) is quite simple.
Of course, I could dial all the settings in the camera and set up the scene, so I could actually just use JPG.
FUJI X CAMERA SETTINGS
Always use Manual settings
Set ISO to the lowest possible and shutter speed the fastest. When shooting from a handheld depending on the light and aperture you probably can't use ISO 160 and 1/100s or faster speed.
1. White balance Daylight or Kelvin 5600. Of course, when shooting JPGs only, then you need to set the correct WB for the scene.
2. Noise reduction -4
3. Set Highlights -1
4. Set Shadows +1
5. Sharpness -1
6. Color +1
7. Classic Chrome or Pro Neg. Std film simulation (this does not affect RAW files)
* Expose the image at least 1 stop brighter, so there's less noise in the shadows.
* Because watch crystals are reflective, I sometimes cover the light that shines on the dial with some dark cardboard or whatever. This can be simple or complicated.
* Shoot from a tripod when you can!
* Use some white reflective cardboard or blank paper to reflect the light on the watch's case.
POST-PROCESSING RAW files
1. First I adjust exposure to my liking. I also use the calibrated display (DELL Ultrasharp 10-bit 32"). I prefer rather neutral exposure.
2. To bring out case structure I always decrease highlights. Sometimes -100
3. Increase the shadows, but not always and mostly like +30 max
4. Color + or - depending on a scene and watch. The outcome should look as close to the reality.
5. I like to add vignette to my shots. This emphasizes the watch more because the corners are darker. Matter of taste.
6. Add little sharpness if needed. The shot must be in focus first!
7. Export the result as a maximum quality JPG file (normally 25MB).
