I got a new computer for xmas and now I can render large images using Poser 7.  It sure is fast and fun to play again.

I have one problem.  I go into RENDER DIMENSIONS and set my width and height and set the resolution at 300 and click the OK button.  I render my piece and it looks good.  So I go to FILE / EXPORT / IMAGE to save it.  When I save it , my images are not 300 ppi/dpi but 72 ppi/dpi.  I saved them as a .png, .tif. bmp and .psd for a test and all of them save as 72 instead of 300 ppi/dpi.  I double checked to make sure the setting was at 300 not 72 before I rendered.

Can anyone please tell me what I am doing wrong or give me a tip on how to save the setting at 300 instead of it changing to 72?   Also, what format (.png, .tif, .bmp, .psd) do you save your images?  I always used .tif before in other versions and the 300 took.

Thanks for any help you can give me.

for some reason Poser always saves at 72dpi - what I do is to take the actual dimensions I want to render at (say 10x8 inch,) multiply by 300 (3000x2400) and then resize it in Photoshop.

Open the image, go to Image -> Image size
untick resample image and in the DPI box type in 300 and Voila - the dimensions change to 10x8

I usually save as PNG

Thank you so very much.  I have been going crazy trying to figure this out.  I wonder why it changes to 72.

Appreciate your time.

But that is the probleme of Poser 7 to save the images with such a low quality. With Poser6 I can save in much better quality. A point why I still prefere Poser6 for closeup renders. 
I really wonder why I can set the resoluton to 300 or more, if I only can have 72 at the end? That´s nonsense, isn´t it?
I´m still not a fan of Poser7.

There have been lots of threads about this if I remember correctly.  The dpi (actually ppi - pixels per inch) that you render at has no effect on the final print. 

a 3000x2400 72dpi image is exactly the same as a 10x8 inch 300 dpi print

Very interest! Once somebody told me that more dpi would show (print) more colortones. Isn´t it true? So by sample, if I render an image 1200x1200 and 600 dpi hasn´t it not more quality as 1200x1200 and 72 dpi?

1200x1200px at 600 dpi has exactly the same quality as 1200x1200 at 72 dpi. The only difference is the print size: 1200x1200px at 600 dpi is 1200/600 x 1200/600 = 2x2 inches, while 1200x1200px at 72 dpi = 1200/72 x 1200/72 = 16.7 x 16.7 inch.

Oha! So thanks! I never will learn out as I see ;-)

A lot of people want the 300 ppi for their prints.  I know I do.  72 ppi makes bad prints.  It seems to me this would be something important for the people who produce the Poser program to fix.  I will be using a different version of it now until it is fixed.

Thanks so much for all your help.

I don't pay any attention to dpi when I save my rendering.  When I print out on photo quality print, it always looks great-providing I don't run out of ink.  As for what format I save the master in, its .tiff because of the mask (alpha channel)-then I can use it in VUE as a billboard-4 polygons render a little faster than .pz3 polys.  Sorry drifted off topic a little--Plutom 

The ppi/dpi settings are ONLY useful when you specifiy your render size in inches/centimeters.

The calculations are simple: number of pixels=dpi*number of inches. (both in horizontal and vertical dimensions). This is what Poser uses to calculate how many pixels it should render.

At what resolution you're going to print the image - well, that's up to the user. Do you want to print the image at 600 dpi? Fine, but the print will be smaller by a factor of 2 in each dimension. 150 dpi? Then it'll be poster size. 

Remember, you first determine how big you want your print and at how many dpi, then you set those dimensions in Poser/Vue/Max/whatever, render, export the image, and don't worry about the dpi settings the rendering app happens to put in the .psd, .tiff, .whatever. You can and should set the right print settings in your 2D graphics program (Photoshop, PSP, Gimp, whatever).

100% agree with svdl.  DPI settings are irrelevant except when it comes time to actually print the image.  If you know the physical size of the image to be printed and the DPI to be used by the printing device, you render (pixel dimensions not dpi) to that size.  So if the print is going to be on a device using 600 dpi and the print will be 6x8, thats 6600 and 8800 or 3600x6400 pixels - period.   You can go higher if you want a higher quality source but you don't want to go lower unless you want interpolation. Setting the dpi in the render to 600dpi won't make it print at any better a resolution if  you are only rendering 360x640 pixels, for instance.

Although the dpi setting in the file may impact printing, most 2D software lets you specify everything (paper size, type, print dimensions) including the dpi setting to use.  It is rare these days for the dpi in the file to take precedence over the print settings.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
