H4D-40 Print size

Hi - I'm considering purchasing an H4D-40 - could you tell me what is the largest size prints that can be made without loss of quality and without up-resing?

Thanks in advance!
 
Larger prints are no problem.
Super large is possible by software that calculates missing pixels for extreme print sizes.
 
On One Software Perfect Resize 7

This is the industry standard for making huge prints beyond the native output resolution of any digital camera. It previously went by the name Genuine Fractals, and this latest version is now part of On One Software ... makers of other industry standard post-processing software like Define 2 noise reduction, among others.

They offer a 30 day trial .... so you can see if it'll work for you.

Be aware that to go really large, your shooting technique has to be perfect whether up-sizing a H4D/40, or shooting with a H4D/60 ... every error is magnified.

In past, I have made excellent 8' wide display panels for trade show applications where viewers are only a few feet away from the photograph ... and that was back when I was shooting with a H3D-II/31. The H4D/40 would be even better.

All images larger than the sensor are up-res'ed, are they not?

The linear density of the pixels in a sensor are different from linear density of print.

Modern sensors have 5-6 micron spacing, while prints at 300 DPI are about 84 micron spacing. So you get a straight magnification of 84/6=14 for 6 micron and 84/5=17 for 5 micron while printing.

Lets us calculate it for H4D40
6 micron sensor spacing
43.8mm sensor width
7304 pixels
at 300DPI printing width is 43.8 * 14.1 = 619mm
at 360DPI printing width is 43.8 * 11.6 = 508mm


So for prints larger than mentioned above you will need to calculate the extra pixels, and that is up-res.

Just an interesting note, I did an image for the studio

it measured 1189 x 3000 mm.

bearing in mind it was a high key image slightly desaturated. Shot H4D-40 with 35-90 lens
