300 ppi render shows as only 72ppi in Photoshop. What gives? Poser 7 and Photoshop CS3. File saved as a PSD.  High res images from elsewhere show proper ppi. But never poser.

FYI - DPI just means a bigger render, displayed in a smaller space(usually for printing purposes).

Show us a screensot of the Photoshop Image Size dialog.

Check the Dimension in Photoshop(Edit > Image Size.)  If you check Resample Image, and need to make the dimensions smaller (to match what you had in mind with Poser) does the DPI change to 300?

If not then you did'nt render at the size you want yet.  Next time you render, change Posers render dimensions(Or just change your Preview window size) to 4.167(300 / 72) * (times/multiply) what it is at now, and render.

Yep, DPI is meaningless in this context. If you render at 1000 pixels x 1000 pixels, changing the DPI - or more correctly PPI (pixels per inch) - doesn't alter the total number of pixels.

And anyway, this is one of the annoying little glitches that seems to have disappeared after applying the most recent service pack.

I usually go to Render>Render Dimensions> then change the Resolution to 300 dpi and increase the size to ...Height x Width pixels or what ever size you need and  your machine can handle. It's usually a good idea to make the image larger than needed, then reduce it. 

Then Render>Rendersettings>Quailty, Firefly, auto setting, and moving the slider to Finial. This should give you a decent render. You can really puch things up with more options, but I think this is a good start.
 
If your Dimenisions are not proportional to the window size, be sure to deselect Constain Ratio proportions.

If you're doing an image that is going to be layered in Photoshop you can export it as a PNG file. 

Have you installed the service releases. There was a problem with DPI put right by SR1 the readme for SR1 stated

*- Now exporting images at resolution (pixel per inch) specified on Render Dimensions dialog.

*Sounds like your problem
