<<But You know those agencies that reject 18 MB original files, but happily accept Genuinely fractalled ones if those surpass 50 MB limit, although each pixel is simply mathematically/geometrically quadrupled. Why not make THEM happy...?>> Peeter OK, that's a good enough real-world reason. But too it's no reason to stop "campaiging" against the idiocy of such "50 Mb" requirements. At the camera level the dumbest of all (hello Fuji) are those cameras that digitally extrapolate upwards to produce bloated file sizes / higher pixel dimensions. The reason (picking through all the spin) was that customers had come to ask solely about output pixel resolutions instead of the sensor ones. At the print agency level: maybe they don't employ people with enough brain cells to operate Irfanview? Maybe (on a kinder note) they prefer to let the customer do the upsizing because it removes the responsibility (blame) of doing a bad job ... that is failing to obtain full feather detail from a 50-pixel high robin bloated up to 80 by 60 inches ;o) I agree though: there are times when you just have to go with the flow even when it's going the wrong way !!!
