You can use Photoshop's Vanishing Point filter for this. It's easiest to use a 3D-capable version of Photoshop,¹ which I presume you have, since you haven't mentioned any other 3D software. There is an alternate path for those using a version of Photoshop that lacks the 3D features, which I will cover inline below. This technique works best with a ...

Lab is one of those colour spaces that people are either 'in the know' and use when it's appropriate or they just see as a bit of a scary place to be avoided. It's not a one-size fits all space and it takes some getting used to. The main reason to use Lab in a professional setting is that, once you get a handle on it, having Luminosity and Colour kept ...

In the Save As function the 0-12 quality scale is used, but in the Save For Web function a 0-100 scale is used. That 0-100 scale is probably close to the 1-99 scale specified in the standards. I compared the file sizes from the different settings, using a 21 MP image (so that the metadata is tiny compared to the image data), and came to this approximate ...

If you are doing much of this sort of work I would seriously suggest investing the time to learn Blender 3D - it will not cost you more than time and the sweat on your brow as it is completely free, (both without cost and Open Source), to get and to use for any purpose. It is cross platform but obviously needs a reasonable amount of storage and processing ...

Either you do it manually or by building a 3d model in a third party 3d modeling tool (or from a 3d scanned point cloud converted to a surface) and applying textures in Photoshop using Photoshop Extended's 3d model support. As far as I know, Photoshop doesn't have an automatic tool for figuring out geometries of a scene by image processing magic. (And even ...

Personally, I make use of Photoshop plugin - Alien Skin with which you can simulate the film behavior to your image, applying filters(to simulate for example polaroid film effects). The basic Alien Skin plugin is the Exposure. You can use it either as a Photoshop plugin or separately. Moreover, there exist another similar software called nik software. As ...

First, the color balance looks plausible in the picture you post, but of course I wasn't there and I don't know what the guy's skin color really is. Second, stone is a bad gray reference unless you have specifically measured it. I think your basic mistake is assuming the stone is supposed to be gray. Since you give not justification for that, I'll assume ...

The high pass filter is not something that can generate a mask of the skin tones within an image, hence why you wouldn't see much success trying to use it for this purpose. One possible solution would be to use PhotoShops Select → Color Range... option. I think in CS6 onwards there's an option in the Select drop-down box of "Skin Tones" This can be used ...

The contrast is low. If you open up curves in Photoshop, and take the point on the bottom left and drag it up, you'll notice that hazy look becoming more apparent. To keep the black tones however, also take the middle point and drag it down a bit to bring shadows back in, and experiment until it looks how you like. As for the color, a simple warm photo ...
