Lightwave rendering for 300DPI printing Please?

[nixx]

In Photoshop, you can change just the dpi without affecting the pixel size (only the physical size will obviously change accordingly). You just have to uncheck "resample image" in the resizing panel.

There is a rule for the render size: Multiply the Inches of your width and height by the dpi you need.

For example:

8.5 by 300 DPI = 2550 Pixels
11 by 300 DPI = 3300 Pixels

That would be for a letter size page. 2550 x 3300. Later in Photoshop you can change the dpi to 300 and it will have the size you need.
If I remember well, I read that in a Lightwave manual, long time ago.

DPI is irrelevant when you render.

What you need to do is find out the resolution (pixels) for a given DPI, for a given physical size.

A4 (8" x 11") @ 300 DPI = 2400 x 3300 pixels
A3 (11" x 16") @ 300 DPI = 3300 x 4800 pixels

and so on...

Actually, A4 is 3508 x 2480 ;)

yes best thing really is too render as big as is humanely possible..

i once had to render a 7000 x 6000 image , would only work with Fprime and the low memory TGA option..

then in PS as was said alter the DPI without re sampling the image..

cheers

A very BIG MMMiaww to you all for this help, I had a feeling it had to be in photoshop or maybe even in Fprime (I've heard), thanks again for the rapid response..

go to photoshop
create new image at the recommended size (24 * 36) at 300 dpi

go to image and resize, untick resample image, change 300 dpi to 72 dpi and what the dimension it give in the pixel section is what you render in LW

Or use Matt Gorner's DPI_Camera (http://www.lwplugindb.com/Plugin.aspx?id=c76cd70b) plugin.

You don't even need to do that, go to resize and change the cm's to pixels and it'll tell you what size it is. I think that's where a lot of confusion sets in, it doesn't matter how many dots per inch, just how many dots in total.

I believe some one over on the lightwave forums made a free plug-in that helps you set up for print renders.

[Lightbase]

Use this Free LScript: DPI Camera v1.2
