下面的过程请大家先把图片下了，跟着用幻灯片播放，作者本身是没文字说明的，就是这个原因．我自己也临摹过，如大家有问题的请提出，理论我想我还是能充充的．
process 01 - hidden industry
Tutorial page for the "hidden industry" picture. Ten steps where i have tried to describe the way i work.
STEP 01
this is the first sketch i did on the wacom. no other drawings necessary. major dark blocks. the background cavern is already quite there, but remains voluntarily brighter than the first closer area. the dark squarish areas on the buildings are just reminders of tones i'd like to obtain later on. no opacity on the background.
步骤1
这是用数位板画的第一张速写,也没再画其他参考草稿. 先填充主要的大块暗色区域.背景洞窟是留空而成 ,比靠前一点的区域都亮.而建筑物上的块状暗色是暗示稍后将要用到的色调.
STEP 02
defining the foreground : adding details, and orange lighting under the main building, hanging cables... docks added on the water.
步骤2
开始定义前景:添加一些细节,主建筑物下面的橘黄照明,悬挂的电缆....还有在水面加入了船坞.
图片如下：
STEP 03
defining the background. it is really too dark and too detailed for my taste, but i'll push it away later by adding brightness. i feel logical to paint the background with cold blue tones, not only because of the sky opening, but also in order to keep the action and interest of the picture on the foreground.
步骤3
定义背景:觉得背景建筑物部分有点偏暗及细节太多,稍后要增加亮度.至于用色,用了蓝色的冷调,这是合乎逻辑的做法,不仅仅因为朝天洞穴的光线偏冷,更是为了对比,以突出前景.
图片如下：
STEP 04
decided to make the background building even more detailed than what i expected. quite dangerous for the image balance, i will have to hide it later on. i'm beginning to paint the sky and the cavern with more opacity.
步骤4
决定在背景建筑物添加比预想要多的细节.处理不好的话会影响到画面构图的平衡.稍后必须抹掉多余的东西.并加大画笔的不透明度来细化天空,洞窟.
图片如下：
STEP 05
minor step. i just need to reassure myself by adding temporary lights here and there. i'll keep the lights on a layer during all the process.
步骤5
次要的一步,作为调剂.这里那里的添上临时灯光,都画在单独的一个图层上哦.
图片如下：
STEP 06
this is the "detail" process. concentrating on adding realistic touches here and there. probably the longest and most rewarding step. i leave the background for now, working on the middle of the image, and leaving the rest for later on.
步骤6
这是"详述"的步骤.将注意力集中在增加各处的真实感上.可能是最耗时但亦最得到满足感的一步了.把背景和其他部分留到后面,集中处理中景部分.
图片如下：
STEP 07
the "background" stage. important stage : with the help of color dodge, i try to make the cavern even wider and brighter than it is, in order to separate it from the foreground building. the main idea is to give a realistic distance to the background. before doing so, i worked on the rocks in order to remove that airbrush feeling that we could perceive on ealier steps, upper right.
步骤7
轮到处理"背景"阶段,很重要的一步:为了使作为背景的洞穴与前景部分分离,以增加其真实的距离感,使用了color dodge(此为何物？我的ps是中文版，好象是个图层模式吧）让洞穴看起来要更宽更亮．在这之前还得消除画岩石时留下的喷笔痕迹．
图片如下：
STEP 08
finishing ground and liquids. warm tones, in order to make a link between the building and the lower water. this way, all the foreground becomes warm.
步骤8
完成地上及水面部分，因为灯光的关系使用暖色调，将建筑物与水面之间的空间联系起来．
图片如下：
STEP 09
Painting process is over. the background has been flattened a bit with the use of the linear gradient tool : blue layers that i erase on the foreground. i'm satisfied now with the difference between the two main areas.
步骤9
作画过程结束，开始调整各部分层次关系．增加了一个半透明的蓝色渐变图层，使前，背景的层次更加分明．
图片如下：
STEP 10
the very last touches. duplicated the main layer in order to add the "watercolor" filter in some areas. especially in order to force some contrasts. removed the filter effect on all the light halos. i finished the picture in approximately 7 hours. during a period of two days. a fast drawing indeed, compared to some of my other works.
步骤10
添加最后的高光．用watercolor牌滤镜做出灯的光晕 ．
sparth在两天里用了大约７个小时完成这幅作品，说是已经很快了比起他另外的那些．
