We will create a realistic briông chồng wall using Photoshop’s 3 chiều features, & a Depth map. We will also discuss Bump Maps và Normal Maps which can add more detail and realism to 3 chiều objects.
Bump Maps in Photosiêu thị 3D
Bump maps are grayscale images that allow you khổng lồ fake detail in 3D objects. The detail that they generate is simply a lighting triông chồng on the surface of 3D objects. The actual 3D geometry is not changed in any way.
The 256 different levels of luminosity inbump maps are used lớn tell the Photoshop how far to lớn push down or pull down.
Bump maps are really easy to lớn create using Photoshop’s 3 chiều filters. Go to lớn Filter > 3D > Generate Bump Map. This will bring up the Generate Bump Map dialog box which gives you an interactive sầu 3D previews, with controls on how to lớn generate the grayscale image that will hóa trang your Bump map.
After you generate your Bump map, you can edit it with any of photoshop’s regular adjustments, tools, or filters. One comtháng technique is lớn use the Dodge và Burn tools khổng lồ adjust the luminosityof certain areas.
Even thoughBump Maps can be very useful in many projects, their drawbachồng is that in certain angles they bởi not look very realistic.
Normal Maps in Photosiêu thị 3D
Normal Maps are very similar to lớn bump maps. They also allow you to fake the illusion of depth and detail on a 3D object without actually adding any 3 chiều geometry. But Normal maps vì it in a different way.
A normal map uses RGB information that corresponds to lớn the X, Y and Z axis in 3 chiều space. The RGB channels tell Photoshop the direction of the surface normals are oriented in for each and every polygon.
Normal maps are as easy khổng lồ create in Photosiêu thị as Bump maps. Go lớn Filter > 3D > Generate Bump Map.
The Generate Normal Map dialog box is almost identical khổng lồ the Generate Bump Map dialog box. It also gives you an interactive 3D pReviews, with controls on how to generate the image that will hóa trang your Normal map.

Unlike a Bump map, Normal maps can be very difficult edit in Photosiêu thị. Each RGB channel is adjusted to present a movement in a single axis in 3D. This means thatany adjustments would need to lớn be made the appropriateRGB channel, and not the whole image.
Depth Maps in Photosiêu thị 3D
Depth maps are 2 chiều images that use their luminance values khổng lồ create 3D objects. Unlượt thích Bump maps or Normal maps, Depth maps in Photocửa hàng do alter the 3 chiều geometry of an object.
In this tutorial, we use a Bump bản đồ as a Depth maps lớn create our 3 chiều object.
This image was also created using a Depth map 3D modeling technique similar khổng lồ the one shown in this đoạn Clip.

Hi J,
I did enjoy this lesson & spent a lot of time on it, as this is new information for me. I will split my lesson nhận xét sessions into smaller chunks for now though since, like an old file cabinet, too much new front load causes random files khổng lồ fall out the back!
I did have sầu significant difficulty following without frequent rewinds as the control panels are small và blurry, especially following along with a split screen (I use windows và have sầu a large desktop monitor).
I would vì much better with a separate window on your screen that shows the editing selections as (or more) prominent than the sản phẩm results. I have sầu the lathử nghiệm versions of Adobe & a strong machine, but my control options vary from yours at times, which is another reason why clear directions are imperative sầu for those of us who are unfamiliar with 3D controls on PS. Sidebar: my tools are mix to lớn mặc định & yet my selection marque only offers a 2D vertical or horizontal line without any scrolling rectangles (used lớn select render area). So, I just used the lasso (which looks different from yours too).
In this lesson, I really liked that there is not any background noise and that your voice is easy to understvà.
For me, watching a đoạn Clip has tremendous value but, having a hard copy flow sheet with simple graphics is handy, both would be amazing.
