A couple of clues: 1. In the image you posted, when opened in Photoshop, there are several paths, possibly used to aid retouching. 2. The added "light source" is very suspect, not matching any light source in the original photo (see attached - where is that light?). My guess is that it was all done using traditional retouching techniques in Photoshop, without the use of 3D. But that's just a guess. And yes, it was probably HDR, and probably retouched in 16-bit.
Note reddish lines, projecting flat-plane shadows on the floor to the non-existent light-source ...
I am pretty sure there were multiple photos with different light conditions (please note the table shadows). Photos were combined later in the final composition with color correction and enchansement involving or not HDR workflow (16 or 32 bit photos can provide a lot of room for tweaking themselfs).
I have the experience of that kind of images. Here is a good sample of how that can be done: http://www.euphoria-imaging.com/portfolio/interior-hotel-marriott.html
Thank you DrStrik9. You are right...There are several path in some photos. I agree with you that there are no any lighting source in orginal photo even though HDR. In this point; it seems to be made of the traditional high-end re-touching. I think the most important distinction in here and espacially in VRX and Atticfire's site; photographs does not look artificial. They are looks very impressively natural. Retouching is completly different subject but espacially interior and hotel re-touchs, but i could not find any satisfying interior high-end retocuhing educational video on net.
Thank you Yahor. I also thinking that was multiple photos to combine final image as HDR. I also looked your site that you mentioned above. That was also good referance for this question. If i understand correctly, you are also saying there are no extra lighting plugin for this kind of works. Just traditional but high-end re-touchs will be enough for ideal results. May be i can ask that which professional HDR program can you suggest for this process. HDR Efex Pro from Nik Software? or more other programs?
Interior retouching for hotels is much like many other forms of image manipulation: it requires good source photography, each photo with 5-7 exposures to get HDR, a good eye, and knowledge of general retouching/enhancement techniques. As in other kinds of image development work, the artist learns what works for his client's success, and develops techniques and procedures to accomplish those goals. Although there may not be many (or any?) tutorials out there for the very specific hotel interior market, it is possible to learn about the many capabilities Photoshop has for image development, which apply to many markets.
I learned, for example, how to get great HDR from an 8-bit desktop scanner in my efforts to restore antique photographs. I did this by learning what HDR is and how it is created by photographers, and then applying that knowledge to imagery from a source other than a camera. At the moment, not all tools are available for retouching in 32-bit in Photoshop, but 16-bit allows a great amount of flexibility and control over the image data. As you learn about Photoshop, I'm sure you will be able to apply that knowledge to whatever kind of work you choose to do.
Your sensitivity to what looks real and what looks artificial will serve you well as you develop knowledge, techniques, and procedures.
EDIT: Oops, forgot to mention: HDR Efex Pro 2 is an excellent tool.

For HDR merging I used HDR Pro build in Photoshop. The aim was not special-looking effect but to get 16bit document with a lot of details in shadows and highlights. Then I used dodge-and-burn technique to bring more attention to desired details.
Thank you for this useful informations and kindly support. I agree with you. Photoshop and re-touching is quite different world and as you gain experience, you are better. Hotels industry also another different world. It's like a city and you can find every aspect of photography.
I'll also try HDR Efex Pro. Thank you.
Thank you for the feedback. I'll keep that in my mind. I'll also try some HDR program to get best interior results. PS application will be one of them. Thank you.
