Adobe II: Entourage, Texturing, and Alignment in Photoshop

Today we will begin with a brief overview of Photoshop. Our focus is on how Photoshop can be used as a non-destructive editing program, looking specifically at region selection, creating image and layer masks, and adding entourage, texturing, and lighting.

In-Class Exercises

We will cover two complementary workflows in class today, one that illustrates the large scope of possible rendered effects that can be achieved by working purely within Photoshop, and a second that demonstrates how to use a rendering as a base layer for work in Photoshop.

Day-to-Night Photomontage

This workflow demonstrates how to realistically turn a building photo taken in the day into a night photo with rain, reflection, and additional scene elements. Emphasis will be placed on the use of layer masks as essential editing tools that overlay rather than corrupt the original image.

Post-Processing an Interior Rendering Using Photoshop

This workflow will teach how to use a variety of post-processing techniques in Photoshop to create an interior rendering that effectively conveys material and lighting effects.

Useful Workflows

Lighting Adjustments & Select Pixel Editing in Photoshop

This workflow teaches Photoshop as a tool for adjusting lighting properties within separate layers and manipulating select pixel groupings for an overall photorealistic effect. Adjustment Layers (including filters and transparencies) and basic pixel editing are emphasized. Students will learn an efficient process in lighting adjustments and pixel editing which can be used throughout the design process; from concept development through presentation renderings.

Layer Management and Image Merge in Photoshop

This workflow teaches Photoshop as a tool for merging separate images into a single unified composition. Layer management and the use of selection tools are emphasized. Students will learn an efficient process in photo editing which can be used throughout the design process; from concept development through presentation renderings.

Creating a Composite Image with the Selection Tool in Photoshop

This workflow will go through the many ways you can use the selection tool to divide images into separate layers of information that can be edited for specific purposes afterwards.

Entourage in Perspective

For this exercise, we will discuss the importance of using entourage in perspective architectural renderings. We’ll focus on how to interpret the relationships of space into the drawing’s entourage according to the horizon line in perspective, the methods used to obtain rendered perspective drawings, and the tools in Photoshop necessary to complete them.

The following workflows are of lower quality, but still may be of some value

Creating a Tilt Shift Rendering Using Photoshop

Tilt shift renderings are used to make a normal environment appear in miniature. This tutorial will go through the steps necessary to create a tilt shift rendering using Photoshop.

Interior Composite Render

We will use Vray to render a Rhino model using artificial lights. Then use Photoshop to compile and edit the final image.

Using Actions for Repetitive Tasks in Photoshop

Actions in Photoshop make performing repetitive tasks faster and reduces the chance of making an error. In this tutorial, learn how to record an action, save it, and use it.
