how to savi render as tiff with dpi settings (?)

[mm-dga]

I always save my renders as a .tif file with an alpha channel.

 

I just use the standard settings ( 8 bit color, no compression and 300 dpi) but is this right?

When I will use the render in eg. indesign, I have to scale it up ( which I guess is not so good for quality ( a samll test shows that when I save as 72 dpi I have to scale down)

well.... didn´t finished there....

 

.- could anybody explain to me if the dpi settings have any impact on the render at all ( I mean a pixel is a pixel)

And what about the image type. would 16 bit color improve the image.

The DPI settings don't matter. Those are more of a sort of calculator for yourself so you if you want to print on 8.5x11 at 300dpi (should be ppi) it'll figure out what your final resolution will be. But like you say, a pixel is a pixel so it doesn't really do anything physically to the rendering.

 

16 bit color will almost never make an image look 'better' in my opinion. What it is good for is for when you get into Photoshop. You can make a lot more color adjustments and such to the image without seeing any sort of banding and that sort of thing. So if you're doing postprocess to the image, go 16 bit. If you're just printing 8 bit is fine.

To get the size you need to render in order to achieve a print resolution of 300 at your final print size (let's just use 8.5x11), all you need to do is multiply 300 (your target print resolution) by each of your paper sizes. So (8.5x300) and (11x300) gives you your render size of 2550x3300. If you render out to 2550x3300, you will get your 8.5.x11 print at a print resolution of 300.

 

It also works in reverse. If you have a 800x600 image and you want to know how big you can render it at a print resolution of 300, divide the image resolution by print resolution (800/300 and 600/300) and that will give you a max print size of 2.6"x2".

 

When rendering for print, it's your rendered image size that determines your print resolution and maximum print size. You can't add resolution in Photoshop or InDesign or any other program.
