Well, thanks to everyone, I really appreciated the help you've provided. To be more specific, the effect I'm talkng about, is the high definition klight that strikes the face, making able to see anything, the beard, the reflection in the eyes, the reflection of light on the hair. I can't really tell, but it's pretty different from any other picture taken from any common used cameras.
I think the question is what filter is used on the photo (cross-process/LOMO, antique, etc.) I don't know about the official names much, but it does look like a type of cross-processing. Check out some of these examples
Well, if my guess is correct. I'm guessing you're talking about the hue changes to the picture. From the looks of it, you aren't too familiar with photo editing. But in photoshop there's many ways to edit photos. From the looks of this they probably had a few duplicate different Hue layers. With a few layer effects. Aka they probably used overlay or something of that sort.
If you don't want to experiment yourself with these types of things, you can always take a shortcut and use photoshop "actions". Actions are a little tool in which there are already preloaded layer effects and such that change the outlook of your image. That's why its a shortcut, because someone else has done the work to use certain effects on images and layers and saved the procedure to use again. Check out some of the "actions" tutorials or downloadable stuff on this site. It's only for Photoshop if I'm not mistaken. But can be accomplished differently in other programs. Hope I helped, if that was your question.
