I've been lookin at the P30 files which captureintegration sent me so kindly (I can provide a download link for one easily if you PM me, they agree to have them distributed) and I'm seeing that I can do 13x19 nicely from a 1.5Megapixelp portrait crop.

I uprez in PS CS2 with bicubic smoother - with my SLR going large from such a tiny crop would be painful - have you people found that the captures from digital backs uprez more easily than those from dSLRs ?

E.Ronald,

Try Qimage. I could not capitalize on it, but few friends found it appealing
as it yielded some good things.

Yes, yes, GF rocks - but this post was simply about my amazement at how uprezzable the Phase files were compared with my 1DsII.

I'd imagine that MF files enlarge much easier than files from DSLRs because the MF files don't fall apart as easily, however, it really depends what program you use to convert your 35mm digi files.  

Medium telephoto portraits hold up amazingly well with just about any high-end DSLR, but the same shot from a P45 or Aptus should have virtually unlimited enlargement.

I have found PhotoZoom Pro to be my favorite interpolation program (not the latest version with S-spline2, I prefer the original S-spline).

i find that with the files from the P20 @ 50 or 100asa and my rollei lenses there is almost no limit on how big you can blow them up...i think there is a couple of reasons: there is no noise whatsoever (true at 50asa, maybe at 100as well), so only the information gets enlarged, there is much less of a pattern in the enlargements (compared to canon files) second: i need no sharpening, (if i know i will blow it up real big, i never sharpen anyway... ) so the funkyness that comes with sharpened edges simply isn't there...a 5x10ft print won't be examined from 6inches (or it should not be)...i have never actually made a print that size and if i would, i would look at a P45...i have taken parts of images and enlarged and printed them (the full image would have been enormous)..and was surprised....
DMF provides better pixels, MF lenses provide much sharper images with better contrast (i am always blown away by the schneider-rollei lenses)...better base iformation makes for better enlargement...
as good as GF is, i almost never use it anymore, because the P20 gives me a native 11x14 without interpolation, if i have to crop, i mostly just rez up to 125% or 150% in C1...i honestly can't tell the difference...with GF you can go up to 400% and the difference is marginal...with a good starting file...
with the canons, blowing up an area where the detail is "digital mush" (hair, skin or foliage in shadow) it just amplifies that and it does not matter if you go 200 or 800% it just takes what is there and makes it worse...

there is a new product by alien skin called "Blow Up", looks pretty promising, but does not seem to have any advantage over GF...

I tried Blow-up expecting it to be some amazing, next-generation technology in interpolation, but I was surprised how awful it was compared to PhotoZoom Pro, or even PS bicubic.  It turned out to be a really weird, awkward looking algorithm, with awkward looking results.
