Andy - I've had a couple done at 30x20 and a good number at A2. Very impressive. I didn't mean to imply that Photobox prints were cheaper - they aren't - but overall, I didn't find that much in it.
Epson 1290 A3
- approx £2.50 (using Epson ink & premium paper) per print (though I believe 2100 inks cost more)
But that, as you say ignores the cost of the printer AND all the prints you don't get quite right first time! Factor in time and effort, and for me the A3
printer no longer seems worth while. If I were doing lots of A3
prints, I'd rethink it, but then again photobox prices drop for quantity ...
One other consideration - hi-res at A3
from a D60 will require some interpolation of the original. I think Photobox produces a sharper print than can be obtained from a Photoshop interpolated image though I would say my uninterpolated prints at A4
on the 890 are slightly sharper than Photobox equivalents.
