DOF and Final Renders. Tip of the Day:

This Was Provided by Szark. Let's all thank them for the help.

When you have your DOF set up and it is time for the final render pay close attention the Pixel Samples X and Y settings in the Advanced Render Setting pane (refer to the images below). The default is 4 and with the changes made in Daz Studio 4.5 these should be good for most purposes. Pixel Samples X and Y are mainly there for anti-aliasing but comes in to play more with DOF. When it comes to DOF these need to be increased. Refer to the low quality render below and look at where the pixilation occurs, the arrows will guide you. smile. The Maximum in DS4.5 is 16 samples. The maximum used to be 64 in Daz Studio 3.


In conjunction with increasing the Pixel Samples X and Y, also increase the Shading Rate quality, lower being better quality. 0.2 should be good enough for most images but you may have to lower it more in some cases. All this super sampling will take care of the pixilation that can occur with DOF.


Super Sampling: This is when we tell the render engine to sample a pixel a number of times which results in a cleaner render. The higher the quality we set the more samples are taken the better the image may be. Yes I said “May Be” better as it most cases increasing the quality higher will just take more time to render with very little increase in quality. The real super sampling is needed when we use advanced lighting and surfaces shaders etc.


So in the Final render below with the Pixel Samples at 16 means the render engine is taking samples of one pixel 16 times on the X and Y axis of the anti-aliased edges.


This relationship between DOF and Pixel Samples depends on the Value of the F-Stop. The higher the F-Stop Value the less blur which requires less Pixel Samples. The lower the F-Stop value the more blur which requires higher Pixel Samples. Since I had a low F-Stop value of 10 meaning more blur (see image below) I used the Maximum Pixel Samples X and Y setting of 16.


Notice I also increased Shadow Samples to 24. This is because I was using soft shadows. The softer edge to the shadows needs more Shadow Sampling. 16 to 18 in generally good but since this image only took 15 minutes to render I set it to 24 to be safe. smile


I found this helpful in regards to Render Settings: http://rubicondigital.host22.com/index.php/articles/poserdazstudio/4-optimising-render-settings-in-daz-studio

We hope everyone finds it as much fun as you do Sasje. Depth of Field is one of those little things that can really help a render sometimes. And it's built right in to DS, Poser and most other programs. I hope to see some fun images this month.

I did this one about three months ago and haven't played with DOF since. I can't enter this because it has allready been posted in the old forums.

I would love it if you all could pick it to pieces and point out where I went wrong.

I was trying to get the focus on the mans face and the gun.

That's pretty darn good version3. I do see just a few things that might have made it better so here you go.

If the focus was more on just the mans face and not the gun and face, with the camera angle giving a full view of his face that would help.
If the DOF was sharper so your background faded more it would also give the image more impact.
I would also have expermented with lighting more. Lighting and DOF together can really pop things and make them stand out. High lighting just the action and having lower lighting for the rest of the scene would help.

Just my two cents.

I think all us Artist have this Blindspot when it comes to our on stuff. I know I do. I do a render and think it's fine, it takes others to show me what could be done to improve it. The feedback I get in the Forums is one of my favorite things about Daz.

I don't care how good some may think they are. The information you get from other users is priceless. There is always room for improvement. I know I'm always wanting input on my promos.

Totally agree. One reason why I gave JAderail one of my older Bryce renders as an example. If I was to do that one now, I would do it differently. I have my camera focused on the front dragonfly, nowadays I would probably focus on the one a bit further back.

My tip for this months competition is for people to check out lots of online photographs and make a mental note of exactly where DoF is most prominent in photos. There are very specific technical and physical reasons why DoF can be utilised in photography and certain constrains in photographic optics that can make avoiding DoF issues impossible... which is why we all need to learn how to use them to the best advantage. smile

Cool, depth of field! smile That's something I've grappled with a few times, sometimes with pretty good (albeit rather grainy) results--like in my July contest entry (http://www.daz3d.com/forums/viewreply/56704/) and sometimes it turns out like the render below...let's consider this a lesson in what not to do. rolleyes To add insult to injury, this render (at 2000x2000 pixels) took a full 24 hours. Imagine my disappointment when I saw the results... I may not have learned much about depth of field from that experience, but at least I learned about the value of test renders (and rendering to a new window rather than a file).

Edited to add: to clarify, this is not a WIP for this month's contest. I'm not asking for advice on how to fix it (although if anyone has advice of this nature and wants to share, by all means feel free). I'll be working on a different project for the contest.

Here are a couple additional tutorials I've found that may be helpful for those using DAZ Studio:

http://greywulf.net/2010/02/easy-depth-of-field-in-daz-studio-3/ (lots of good tutorials at this site)
http://docs.daz3d.com/doku.php/public/software/dazstudio/4/userguide/projects_quick_and_dirty/tutorials/tutorial_the_temple/start This tutorial mentions DOF but doesn't go into the details. Still, the tutorial is interesting, and the finished render is a great example of DOF in DAZ Studio.

Oh, I almost forgot...thanks, Jack Tomalin, for sponsoring the contest! That'll definitely add even more incentive for people to enter and give it their best shot.

Your F/Stop is set WAY to high for a close up render. Lower yours to something in the 30's to 40's range and set the Forward DOF plane right at the front of your figures nose. Also your camera does not have a Standard Focal Length. That is where 35mm 65mm ect, standard camera settings are easier to deal with than none standard ones. Here is what I get with a similar set up.

I try to make a baby portrait.
I never done this before the DOF, so I hope I do it right.
With the camera, I used the top view so I can see it better. smile
No post-work only Daz.
