My only other frame of reference with me out here is my iPhone screen, and they all look okay to me (in other words, they match what I see on my laptop). The only one that frustrates me is that 'Paradise' photo. I even went back at a different time of day to see if I could improve it, but didn't work. The scene faces north, and I think it needs a completely cloudy day, which out here can be a bit of a challenge to get 🙂
Before I left on this trip I calibrated and compared images on my laptop screen to the same images on my 27" iMac. When I started to work on the shots out here, they all looked kinda brown to me, so I recalibrated my screen and adjusted the white point. They look more neutral to me now. And perhaps as far as 'hitting all the zones' goes, it may just be my personal aesthetic approach/interpretation of a given scene, which may not necessarily result in having tones in every single zone. Honestly, I never look at the histogram - I go more by feel and what I think corresponds to what is in my 'mind's eye'. Even with this what some might consider a 'seat of the pants' method, I've generally never had an issue with blocked shadows or blown highlights in either CCD Monochrom or Monochrom 246 files and their resulting prints. Most likely the way I'll continue to work, though I'm sure many won't agree with that particular working method. Oh well.
