Poser Pro HDR output

Let's talk about Poser Pro. One of the new features in Poser Pro is the ability to export HDR or "High Dynamic Range" images. These are written out from Poser Pro as a .exr file and that file is a 32bit per channel image. I'll show you examples and hopefully this will demonstrate why this is so valuable and HDRI is such a buzz word these days. Better I just show you than go on with my usual long winded approach.

When rendering in Poser Pro you will now be able to make the choice to Render High Dynamic Range Images as opposed to a standard image format. This is particularly useful when integrating your 3D Renders into other projects. I've included two files for download at the bottom of the page. The first is a .exr file rendered from Poser Pro, and the second is a .png file also rendered from Poser Pro. You'll need image editing software to see the real difference but here are some screen shots made from those files:

HDRIExposuresSm.png

 This first one demonstrates the range of an HDR image. This was opened in Photoshop CS3 and the Exposure slider was adjusted from about -4.0 on the left to around +4.0 on the right. You can see that there is a tremendous amount of information available.

 

ExposureSM.pngThe range is even more apparent in this example. The image on the left is a .png rendered from Poser Pro and the image on the right is the same .exr file as the example above. The exposure sliders are both set at +3.48. My lucky number of course. Actually I was too lazy to redo the first screen shot. If you look at the image on the left you can see the posterized figure in the background. This of course is partially due to the compression on this file. It's only 8bits per channel. In the image on the right you can of course see the additional information and how smooth the background figure looks.    

I've included both of these files for you to download and mess around with yourself. You'll need an image editor that eats .exr files such as Photoshop CS3. In that particular application you can choose Image>Adjustments>Exposure, from the top menu.  Sorry no Poser Pro UI screen shots just yet but I will post some soon. However aside from UI related to additional features it will be the same UI as Poser 7. I'm hearing the cheers and the boos already.

Steve,

Wold love to see what shaders can do for a very tricky material like East Asian Jade ( not plastic imitation, but the real thing ).

Also, it would be great to see a gallery of amateur-ranking renders done by the existing non-art staff at Smith Micro (i.e. non-e-Frontier people), using Poser Pro. Just for fun.

What are the minimum and optimal requirements to run Poser Pro? And will the 64-bit render engine work on a 32-bit machine?
