Okay, so the conventional wisdom regarding image print resolution was that if your image had a native ppi between 180 and 480, you were better off not up-res'ing. So, I just watched the LL L2R video that covered the print module, and seems like the 180-480 thing may be changing. I'd be very interested to hear from you Jeff on what the "new math" findings are pointing to.

In Lightroom 2.0, I've found that "some" images may benefit from setting a higher PPI setting in Lightroom and then let LR 2 do the output sharpening at that high resolution. Generally, only a 50% or so increase would show any benefit and only on a few images with a LOT of super high frequency textural detail (and I mean super high frequency and it only helps a "bit"). And, that's only with images with enough base resolution to work with.

So, going from 300>360 or 360>480 may show better high frequency detail...but trying to go from 180>480 is a waste of time.

got it - thanks

My question - these numbers you state - these would be printer independent, or would you use different values for a Canon printer vs an Epson vs HP.?

thanks
