I just bought a R3000 because I wanted a very good photo printer along with all the paper profiles I needed. I was tired of limited profiles or the need to pay to have a custom profile made for the regular printer I have.
I am an amateur photographer but not new to the computer end, color workflow etc. I use LR4 and PS CS6, NEC monitors, profiled regularly with an Eye1, the correct printer & paper profiles, decent full spectrum lighting so everything matches nicely except for the usual slightly darker print (fixed with a final mask in CS6 or +6 in the photo LR module). I also know how to technically use my camera, ISO, aperture/depth, WB (though I shoot RAW), histogram, etc.
I bought the sample pack from RR papers and printed similar images on glossy, lustre, satin, linen, canvas etc. papers and can see the significant differences in the photos with the different finishes, I even adjusted for smaller gamuts and what would have been washed out on some of the fine art papers. So now, for the more artistic and what I know to be a subjective and personal taste question by this very literal engineer...
What paper (texture, whiteness/warmth, brightness) for particular subjects, ...
Portraits (I know some pros use canvas)
Well Lit Landscapes
Photos with "flat" water.. Such as harbors with boats
Water with waves
Any other nice matches one can think of, for example...
"I like to use matte papers with ?? photos"
I have looked around allot and can't seem to find this kind of advise.
