Daz3D 4.8 save render as 16 or 32 Bit per channel tiff or png using Iray

Is there an option to save rendered images as a higher than 8 Bit files so the render has trillions of colors instead of millions?
Just trying to see if I can get more dynamic range into the file for compositing, color grading purposes like recovering highlights or lifting shadows in post after the render.
Thanks

only options I see are, tif, bmp, jpg and png, sadly
In the Advanced tab check the Canvasses option, click the + to add a Beauty pass. It will be saved as .exr.
Thank you!
If I do this, my render comes out as fully transparent, no content. I'm not prompted for an EXR filename, either. I tried adding all the nodes to a node list. I tried toggling the alpha checkbox. No Joy :(
I'm trying with a test scene of a character and a couple of props, using HDR environment lighting and nothing else just to make sure I've got the concept down - which I clearly don't.
When you save the render, as MyImage.jpg say, then a folder will be crated called MyImage_canvasses with the .exr file. I should have added that you need to create a Node List, then click the ... button and add the items in your scene to the list, then tell the Beauty pass to include that node list. Also, if you are using Photoshop, you will need to use Image>Adjustments>HDR Toning to get anything useful.
Aha! That did the trick. Thanks Richard!
This should be on page 1 of the daz site or as a pop up option when the app is launched. It's THAT important to professionals who would otherwise not know.
Baby-steps... The IRay thing is new... Still have a few bugs to work-out, and limitations to lift... Then I am sure they will have those streamlined options more readily available.
I am still waiting for them to get the depth-maps and other components to function, for similar reasons. (Canvases all show as pure white or black, for many of the options.)
The canvasses, if you load them into Photoshop, need the application of Image>Adjustments>HDR Toning. I believe you may be better off using soemthing like Fusion or Autodesk Compositor, though I haven't yet tried either.
A nice, full featured, OpenSource (free) compositor...that can do stills (single images) is Natron. It can deal with the output of the Canvases...

Mr. Haseltine, thank you kindly for the responses in this thread. Totally took care of a number of questions I had. :)
Glad to have helped.
Okay so I've tried this EXR thing .. I have rendered a PNG and an EXR .. but the EXR is mostly white with sime detail and colour. My version of photoshop is old and doesn't have and HDR features .. but I could open the EXR in Final Cut, and I did downoad Natron too but frankly I don't get that program. My question is .. what the hell are you meant to do with the EXR? Are you meant to composite it with the PNG file that you also get ... isn't that pointless .. mixing a 32 bit file with an 8? .. The whole point is a just want a 32 bit render.
So did I do something wrong with rendering the EXR or is that how it should look ... mostly white?? If I didn't do anything wrong then what's the deal with just getting a 32 bit image.
The reason I wantm and need a 24 or 32 bit image is because I'm doing animation and when trying to apply filters to an 8 bit image you very quickly start to see colour banding .. so I need the higher definition of colours, and colour space.
Many thanks in advance. Atleast now I know what tht canvas thing is. Why the hell DAZ can't put out a thorough manual is quite anyone's guess.
In Photoshop, depending on the version you're using, you can either do an exposure adjustment for the whole image, or add an exposure adjustment layer, and reduce the exposure down to between -10 to -14. The actual amount will depend on the scene and how much (or little) light there was.
I have CC 2015 now, and personally, I don't think you're missing much by not having the HDR Toning option. 9 times out of 10, I end up using just an exposure adjustment because the HDR Toning tends to make the image look overworked to me.
I kept seeing references to canvasses and rendering exr files, so I decided to take the plunge and figure out how to do it. That's how I found this thread.
The first thing I noticed was how apparently unusable the image was, mostly blown-out white. So I came back here and finished reading all the posts!
I have Photoshop CS6. Using the HDR Toning adjustment, I was able to adjust the Exposure and Gamma and get the image I was expecting. On a hunch, I opened another exr render and used the adjustment layers to change the Exposure and Gamma and found that worked just as well. And as an adjustment layer, I have the option of going back and changing the settings. (While I prefer using the adjustment layers, you can also go to the Image > Adjustments menu and select Exposure to open a window with the same options as the adjustment layer. When you apply the changes, they will be applied directly to the image.)
Like KursonDax, I thought the HDR Toning made the image look "overworked," even after tinkering with the settings. The only thing the HDR Toning appeared to be good for was using the Exposure and Gamma method to restore the missing details of the image.
But I'm a curious lady, so I did some testing and discovered the Exposure and Gamma needs to be adjusted and applied separately before applying anything from the Local Adaptation method. By separately, I mean if you use HDR Toning to adjust the Exposure and Gamma, you need to click the OK button and let Photoshop apply those changes first. Then reopen HDR Toning and make your adjustments using the Local Adaptation method.
I've attached two images. One is a side-by-side comparison of the same image, the left has the default HDR Toning applied without using Exposure and Gamma first, the right has default HDR Toning applied after the Exposure and Gamma adjustments were applied. The other image just shows the dialog window for HDR Toning, with the Method drop-down window exposed. I figure it will come in handy for somebody.
Thanks to everyone who posted here. Your conversation helped me a lot.
You can also create a node list from selected objects. That's how I did it. But somehow, two objects parented to body parts, (hair to head, pistol to hand,) weren't selected within the Node List. (I didn't click the … button so I didn't realize it.) The gun is black and so is most of the hair. The area where these two objects should have been was rendering as black, (which wasn't obvious in this particular image,) and I wondered why using the canvas should affect them. Oops. I discovered my mistake when I decided to see what checking the Alpha box did, and the checkered background showed through in the render window.
Anyway, just thought I'd mention this in case it can prove helpful to someone else, somewhere down the line.
Excellent. Thank you!
Couldn't agree more......BTW, for the non Adobe minded crowd.......I just downloaded Gimp 2,9.6 and it didn't make my computer explode but it can use .exr files like DAZ pukes out so beautifily, love it!
Greets, Ed.
BTW, thanks SoldierOffFortune for the exelent question as well.......
