output for printing

[mon_stdnt]

Im planing a 13in landscape render of a glass bike. My question is what are the settings for that kind of render.

I have a resolution of 2000 something by 1000 something at 300dpi, but when I open it in photoshop the print size is around 4in.

Any suggestion, Oh and what is the differents between Resoultion and Film Format?

To render from a 3D soft you just need to care about the size in pixels and don't bother yourself with dpi.

That way for metric size it work like this : an A4 (portrait)document at 300dpi is exactly 2480x3508 pixels.
To know what is exactly the size in pixel (for print) of your document, create a new document in photoshop with the size needed at 300dpi - validate - and then go to menu image - image size and you will see the size in pixels too !

Sorry for my english, but i hope it will answer to your question

if its still image with a lot of glass or metal, I would render, at 7800 x 3000, (or at least 5200 x 2000) and then sample it down to 3900 x 1500 in PS.
You will get a much smoother final image for print.

Ive render it at 3900 by 1500px which took my about 6hrs, my computer (no-beefy) was sweating begging me to stop.

When Ive import it to ps the dimensions read 50in, so I reduce the size to the final size at 9 x 4.5in with 400dpi, still with the same pixels of 3900 by 1500px. It has multi-pass, which my current version of carrara5P doesn't have.

thank for the imput guys, and Rickei--I'll keep that in mind, I just don't feel like re-rendering it again.
