However, I'm still a bit confused by the Adobe PS statement under "Change the Print Dimensions and Resolution":-
"For highest print quality, it is generally best to change the dimensions and resolution first, without resampling. Then resample only as necessary."
Doesn't the above mean that there would be an arithmetically awkward (non-integer) relationship between pixels per inch (say) and dpi in the printer - which I would have thought would lead to a non-optimal translation, analogous to looking at a monitor image at 103% or 19% rather than 100% or 25%?
Anyway, how does one determine when such resampling is then advisable?
Lance: "worry" about resolution in LR? Yes and No. LR allows selecting a print size (standard or created custom) and Print resolution, but offers no control over resampling. Good and bad. Photoshop guru Jeff Schewe swears by LR's Print module.
Thanks again, Larry, for the link to the Michael Reichmann's tutorial on resolution, which is, thank goodness, very clearly written. I am now confident that I have indeed been doing the right thing all along!
