Sharpness Of Rendered Image Files

PrestonArtworks

I have been using Daz for about 4 weeks and rendered a few portrait images using both the default render settings, and also with the Depth Of Field setting enabled to set the focus point / DOF manually. To my eyes, the sharpness of these images is ok, but not 100% sharp. Photography has been a hobby of mine for decades and I spend quite a lot or time using an image editor to view and assess image sharpness from my camera lenses, and would say my Daz rendered images are in the region of about 85-90% sharp.

Being new to Daz and 3D generally, perhaps I have unreasonable expectations about sharpness of image files from such software, but wondered if what I am getting is as good as it gets, or whether there is some specific settings I could tweak to get (ideally) 100% sharp images?

I have attached an example image to show what I am currently getting.

Thanks in advance for any comments.

In the Render Settings pane's editor tab you may want to tweak the options for Pixel Filter - in the Filtering group.

Richard, in Pixel Filter, my render setting was Gaussian which is a word associated with blur for editing photos, I tried setting it to Mitchell (suggested on a YT video I saw recently) but didn't really see any difference between the 2 outputs.

I guess there is probably a trade off between render times and render output quality, ie, the better the quality the longer the render time, so think I will try some different settings over the next few days and make comparisons. I think zooming in on just the face would also make comparisons a little easier on the eye.

Given that no (real) camera is used to produce these rendered images, have to admit that the quality is very good despite my minor criticism above!

If anyone else has additional suggestions, I would be interested to hear them.

The Render Quality setting cotnrols how fussy Iray is about counting a pixel as converged ("done"). Turning it up will  slow rendering but reduce noise - whether that will ease the perceived fuzziness I don't know (I am bad at seeing noise), it might.
