在传统暗房中,要使产生透视变形的建筑物恢复正常形状,一般是在放大照片时,将放大承影板倾斜,让建筑物较窄的部分靠近放大镜头,较宽的部分远离放大镜头,再结合遮挡技术让画面均匀曝光,便可放制做出矫正了透视变形的建筑物照片。但是,倾斜放大法不易掌握,容易出现建筑物两端模糊或曝光不均匀等现象。 用计算机Photoshop软件矫正建筑物变形却非常简单,而且矫正效果可在屏幕上任意调整至满意为止。下面将制作方法简介于下: ①将需要矫正透视变形的建筑物照片输入计算机(图1) ②用“选择／全选”命令将全图选为选区,再用Ctrl+-命令将图像缩小; ③用“编缉／变换／透视”命令组打开“透视”命令,这
In the traditional darkroom, to make the building with the perspective distortion to restore the normal shape, it is common to zoom in the picture board when the photo is zoomed to make the narrower part of the building close to the magnifying lens and the wider part away from the magnifying lens, Combined with occlusion technology to make the screen even exposure, we can make a correction of perspective distortion of the building photo. However, the tilt amplification method is not easy to grasp, prone to blurring the building ends or uneven exposure and so on. Using computer Photoshop software to rectify building deformation is very simple, and the correction effect can be adjusted on the screen to any satisfaction. The following method will be introduced in the following briefing: ① will need to rectify perspective deformation of the building into a computer picture (2) with “Select / Select All” command will be selected as the constituency constituency, then Ctrl + - command to reduce the image ; ③ use “Edit / Transform / Perspective” command group to open the “Perspective” command, which
