Q:
We would like to render an image at a DPI higher than 72. How do we
do that?
PPPLEEEEAASSSEEEE HHHHHHEEEEEEELLLLLLLPPPPP !
A:
72 is the dpi of your monitor. This is why every picture rendered is
written with 72 dpi. If you load the picture into Adobe Photoshop and
display it 1:1, you get the SAME SIZE as if you would print it. To
change this, render at a resolution you need, then go to Photoshop,
Image Size, LOCK BOTH RESOLUTION AND FILE SIZE on the bottom of the
dialog box, and then change the dpi. The resulution remains, the dpi
gets as you need it!
An example - if you need a 10x10 inch picture at 300 dpi, render at
3000x3000 resolution. If you change the dpi from 72 to 300 as described
above, the image size in pixels will remain 3000x3000, but the image
size in inches will change from 41,6x41,6 to 10x10.
