Does anyone know what technique was used to generate this image?

I would like to be able to achieve a similar result to that of the image, being able to put Daz figures in "real" images. Does anyone know if a result like the one in the photo can be achieved in Daz or another software was used to generate the shadows and the feeling that the figure is really sitting on the washing machines?

Thanks in advace

Make a cube, align it with the washing machines in the background picture, put the figure on it, do the necessary clothing simulation and deformations, sort out the lighting, apply a shadow catcher shader to the cube, render, composite in Photoshop.

Oops, forgot a step. Together with aligning the cube you also have to align the camera position and focal distance.

Interesting, I will be making some test and probably get back with more questions. There are lots of interesting challenges along the way.

There is this product in the store, but I don't own it and can't say how good it is.

wow, thanks, I was not aware there were products like this on the store. I will check it out

My guess, I don't think it's a completely 3D figure.  The face & head is 3D, but I think it's being faceswapped or Photoshop'ed onto a real person.  That's why I think the shadows are real, and not 3D rendered.

For real? I did not think of that alternative. I was sure it was about Daz + some other technique. The hads look 3D too though

Well, every picture is different, some pictures have more 3D elements than others, probably to keep you guessing.  The head and hair is obviously 3D, but there's a lot of suspicious shadows and blurring around the neckline (in other pictures, not this one), making me think it's been Photoshop'ed in.

He could do it like this:
- Put a camera on a fixed stand.
- Take a photo of an empty background.
- Take a photo of real stand-in person.
- Render a 3D model in the exact same pose.
- Use Photoshop to blend in all 3 pictures.  Like, keep the real person's shoes or shirt, and blend in everything else.

I don't think you can do that when you have a non-static background with motion, like traffic or people walking, so his technique will change depending on what's in the background.  Of course, this is all assuming he was the one who took the photo.  If he was downloading random photos from the Internet, he would need to fake the lighting and camera angles.

I think she's all 3d. Here's a link to a bigger picture. The hands are a dead giveaway. I think the thumbs are actually clipping through each other.

They did a good job though. It looks like they used dforce and dformers to compress the pants/legs where she's sitting on surfaces.

But, when you render something in Daz Studio with no background, does it still cast shadows onto the transparency parts?  I don't think so.  I  think shadows are only casted on non-transparent pixels.  So, where do the shadows come from?  Are they 3D shadows, photoshop'ed in, or are they real shadows from a real stand-in model?  If they are 3D shadows, then how do you cast shadows on transparent pixels?

There's a fix for that. It's the matte surface in Iray advanced node properties. It does a lot of cool things, but in this case, it can catch shadows in mid air basically.

Here are a few links: https://www.daz3d.com/forums/discussion/57051/how-do-you-create-a-shadow-catcher-in-iray, https://download.daz3d.com/forums/discussion/comment/1420136/#Comment_1420136

Once you get the hang of it, its a lot of fun to play with.

Edit: Sorry, in that first link, you have to follow DesignAnvil's link to get to the instructions.

Cool, one more thing I never knew about Daz Studio.  Shadow catching is pretty neat.
