Help with picture clarity
I love working in Daz but my one big problem is and always has been one thing. Reliable clarity in my renders, especially with indoor scenes. Outdoor scenes seem to work pretty well for me but when I am shooting indoors, most times, my characters seem to be just a little fuzzy. When I do a spot render to check and see what their faces look like, I'm satisfied but when I render the whole scene it lacks a crispness. I know that is due to the fact that it is only render a small portion and can focus more on that area. I've tried experimenting with spot lights but then I have unwanted shadows. I've also gone into the Render Menu and made adjustments to the Quality(?) dial from 1.0 to 2.0. That's atually what I do to every render. A series I'm working on right now is a good example. I have an indoor Iray lighting set, some ghost lights as well as Spot and Point lights. So I'm starting to think more lights isn't going to do the trick.
Would a better GPU help me at all? If anyone knows any tricks I would be so grateful for a point in the right direction.
Oh, I render in Iray and have a GTX 960

A better GPU would only speed up rendering times and only if the scene fits in the card's memory.
Most of my renders are pretty basic. This one for instance is a small sized living room with two characters.
Just because the scene is 'basic' doesn't mean it won't eat up a lot of video memory. It doesn't take very long for a few very high res image files to eat up all available video memory.
So should I be allowing more render time?
Without seeing the results, it's hard to say, but probably.
As far as I know the type of GPU or CPU doesn't have any influence on the quality only on speed. (samples/min)
The only influence on pure render quality is the "Photoreal" and "Interactive" settings in the Render Mode settings.
These are differnt Iray render types, where "Photoreal" gives the maximum result. "Interactive" uses approximation to get a faster result.
http://www.nvidia.com/object/iray-features.html (the motorbike in the middle shows the difference)
The Quality dial in the render settings... it's a bit mystical I think. I always turn off "Render Quality" and let it render a max. no of samples.
Render Quality doesn't change the "Quality", it only decides when it's time to stop the render. If it stops after 3000 than rendering 3000 without "Quality" enabled is the same result. You also can always stop the render manually and save your result.
For me that just sounds as if your camera is out of focus, or maybe you are rendering in perspective view?
Kind regards, Eagle99
Thanks for that insight Eagle99. I do make "MC" (My Camera) each time I start a new scene. I'll navigate around the page in Perspective View and then when I am ready, I position MC where I want it and hit Render. I didn't know there was a way to focus it. I have little to know experiance with photography. I just assumed that the camera would render as clear as it could. I have never messed with the F-Stop idea (yet) I just makethe camera, position it and render.
I made the same expierence as you some time ago... until I found the focal distance... ;-)
When using the "Univeral Tool" (Tools menu) in perspective view you can see it quite clear in the cameras focal line.
That little ball with the small colored xyz axes. You can position it with the slider in the camera settings.
The F/Stop in the camera settings only controls the Depth of Field if you are using it, as far as I know.
If you want to change the F/Stop for you scene same as a photographer does, you find that in the Tone Mapping section of the render settings.
Kind regards, Eagle99
Thank you! Just to make sure I'm understanding this right...(see picture)
Pardon how rudimentary it is. But if that's what you're saying you may have just saved my Daz Life lol. I would have never thought of that. I've just been crowding my scene with lights and yelling "Now show thier face gooder!!"
Try posting some example images of what is happening...then it will be easier to give specific help/pointers.
If that's a scene from the top with 2 people at the right, and the left thing is the camera with the focus, then you are on the right path.
Kind regards, Eagle99
Yes, that is what I was trying to represent. When I opened a scene that I was having this problem with I saw that the "little ball" was actually outside of my scene, through the wall and out into the nether-regions. That's all the time I had though. I would still like to do a side by side though as soon as I'm able and post for any further advise...or to show that it worked.
Hi Agent Unawares
Where do I find that setting?
Also, the advice on setting the depth of field was sooooo helpful! I am getting the type of renders I hoped for now. But the pixel thing would be good to know too!
It is in Render Settings>Filtering at the bottom. It starts at 1.5. Lowering it can help if edges are coming out too blurred.
EDIT: This only will help if you are rendering high resolution, though. I'm glad to hear you got good results with DOF.
@agent unawares : I didn't experiment with this pixel filtering much so far. Thanks for the hint!
@DDCreate: I made a few shots where you can see the differnces. 0.0 , 1.5 and 5.0.
So you can see it really makes a difference even between the standard 1.5 and 0.0, mostly seen in the eyes.
On close shots like this it can really help to make the image very crisp.
Kind regards, Eagle99
