Hi Everyone
My fellow colleague Bob Callawah and myself are proud to introduce you our new product :
UltraHD IRAY HDRI With DOF - Outdoor Pack 1
How is it different from other HDRI sets?
Unlike most of the others, this one is optimised to easily use Depth of Field. Please check the video for more infos on how it achieves that.
How is Depth of Field important?
It gives depth to your render, just like in photography, seperating the main subject from the background.
What if i don't know how to use or activate Depth of Field?
This set provides you a "ready to render" camera wih depth of field enabled, targeting the main character usual position (x0-y0-z0)
Can i use any camera with the environements?
Of course you can. The camera provided here has been put in the same height as the camera when the photos were taken to have the exact same point of view and no deformation at all. If you decide to move the camera or use any other camera at a different position, point of view may change a little but normally not enough to create dramatic deformation.
What if i don't want to use Depth of Field?
Each set (total of 6) is provided with 2 options :
- Depth of Feld enabled, giving you a sharp foreground and a nice blurry background based on your camera properties
or - depth of Field disabled, where everything will be sharp (you then need to use a camera where DOF is not activated or uncheck the DOF in your current camera).
You say Sharp, how sharp is that?
Each set is provided in 16K resolution (16 000 pixel X 8000 pixels)
Ok, that must be sharp but will my old PC/MAC with my old GPU handle that?
IF you think or fear your machine is not powerfull enough to handle 16K environment, we provide 4 different resolutions for each set.
- 16K - 16000*8000
- 8K - 8000*4000
- 4K - 4000*2000
- 2K - 2000*1000
The 2K is adviced to be used in production (so the scene isn't slowed down), and be replaced by at least 4K for final render
What kind of lighting will the environement provide?
The environement have been made to create a very bright sun, creating ultra sharph shadows on the ground and on the subjects.
What if i like one of the environment but the "sun" position isn't appropriate for the lighting i want in my scene?
We provide 12 rotation presets so you can easily move the sun position while keeping your character and camera perfectly aligned with the X and Z axis.
I like the bloom effect in the image you posted here. How can i achieve that?
The set includes 2 "bloom" presets. One to activate it and get the same effect as in the promo and one to turn it off.
Be aware the "Rainbow Halo" in this promo was made in Photoshop as light enhancement, and not in DAZ Studio as Studio is not able yet to create such halos.
What if my question is not answered here?
Feel free to post your question here, we'll answer it as soon as possible :)

Finally something that allows the use of DOF with HDRI's! Thank you!
You're welcome !
I do a lot of promo work and i kinda always use DOF to showcase the product from its environement.
I was really missing something like this so i thought i should create it and that if i needed it, other probably needed it too ;)
This will be an instant buy!
While I think that this is an interesting product for the HDRIs alone, I frankly don't understand the people that think DOF doesn't work with HDRIs. DOF is a camera function in Studio as in real life. Perhaps I'm missing something.
Here are two examples.
The difference from these is that the ground by her feet isn't part of the DOF. I've never been able to achieve that.
Hi Fastbike
In the exemple you post (the monster in the forrest), the background is blurred because of DOF but also the ground and well all the environment has become blurry...
When you want to have a character in full lenght (like in your monster exemple) a good thing is to have an environment that will have the forground sharp and the background blurry (due to DOF).
Point is, as you say, DOF and HDRI can perfectly work together.
This set is optimized in this direction.
In my exemple, the background is blurry like in yours, but the foreground, where the camera focuses, is completely in focus and sharp... If you take a look at the ground under or around her feet, it's perfectly in focus and not blurred at all.
Do you see the difference?
@Cake One
Oh, I saw the difference. Just to be pedantic, whether the foreground is blurry or not depends on where the focus distance is, relative to the depth of field.
I don't want to derail the thread and I agree that the product gives a more aesthethic result than Studio's DOF alone. Most of all, it makes DOF shots more accessible since many seem to struggle with the concept and the application. Studio's DOF is a bit trixy to use and setup since you typically need to switch out of camera view to see the actual field. Studio's camera also tends to have a narrower DOF than would be expected with an equivalent lens.
@Ice Dragon Art
I also agree. Studio's implementation of DOF seems to treat DOF as an "oval" field. In my examples, the area where the Werewolf is standing should be in focus.
In hindsight, I probably shouldn't have commented. My discussion is pedantic and I do like the product.
Don't worry, you didn't sound pedantic at all :)
When creating it, i had an exact idea of what i wanted to achieve.
When time came to explain to DAZ or to anyone how this was different and how it worked, well, it became a bit hard so don't worry...
My real fear was that it wasn't clear what this set could do.
I just hope it's clearer now :)
No worries, if one person is thinking it, I would imagine others are as well and it was a good question. I do struggle with DOF and I have never been able to get the ground under my main character to not blur when using DOF with an HDRI. No idea why but, after hours of frustration, I am more than happy to pay for somethign that works lol.
Hi, I was wondering if I can load any HDRI image into the Environment map and have it work with the presets?
Hi Cerrag
You can load any HDRI image into the Environment map.
The issue might be that if the map itself has not been carefully crafted to support the settings, you might get heavy deformation on the ground or on close items on the map (trees, walls, etc).
Tweaking the settings may help but also may not fully resolve the problem, it really depends on how the environmen map itself was created.
I hope it helps :)
Oh yeah, I totally understand and thank you much! :)
I just did this quick one for a new Tabletop Sci-Fi RPG coming out this fall. So easy to do. Love this product! (Attachment is 4x res)
