I’m looking for D7100 users who shoot/shot raw to try out a DNG camera profile I’ve built. The profile is built from scratch using spectral data, not using any other profiling software.

Very briefly, I’m a former D7100 owner (still regret selling it!) who has been shooting for 20 years and also worked extensively in printing and colour management. I developed a model for estimating the spectral response of a digital camera as part of a science research project, and then realised along the way that I can use it for building camera profiles.

Compared to the Adobe Color profile in Lightroom/Photoshop:
  • The profile has a gentler contrast curve, showing more detail in highlights (eg clouds, hair etc) and shadows.
  • Colours are more accurate. For example, purple flowers are purple, not blue, and red earth/rocks stay red, not yellowish.
  • Consistent hue. No changing of colour (hue specifically) in transition from light to dark. This really helps skin tones (and everything else).
  • Neutral shadows, they lose the red cast often present with Adobe.
  • Overall richer, more lifelike colour.
I’m really keen to have other people try it out and let me know what they think.

If you’re interested, just let me know and I’ll send you a Dropbox link.

Any questions, then fire away.
