Drawing Perspectives by Hand

Perspectival projection from plan using the 'office method'. Both one point and two point perspective drawing will be introduced, as well as shadow projection for the more advanced students.

Fluency in the canonical methods introduced in this workshop will be reflected in the ability to:

  • Understand the principles of one and two point perspective drawings and use them to create a drawing.
  • Apply the techniques of linear projection in order to produce an accurate depiction of shadows in perspective drawings.

One Point Perspective

One point perspectives can seem a bit more boring or static than two-point perspectives, but are a lot faster to draw by hand. Often, one-point perspectives are often used to depict the space between walls or a pathway rather than the building itself.

One-Point Perspective Workflow

Two Point Perspective

This is the most common method of compiling a perspective from both a plan and section drawing. The problem set for this session will be on this topic.

Two-Point Perspective Workflow

Shadow Projection in Perspective Drawings

Properly projecting shadows in hand-drawn perspectives is one of the more challenging tasks in technical drawing. The mastery of this technique reflects a high-level of understanding of graphic projection, and is an excellent grounding for 3d modeling techniques.

Introduction to Photoshop

Photoshop is a pixel based program and should be used to manipulate images/photos. Photoshop is most often compared to Illustrator, a vector-based program that is used for vector layout and graphics. Unlike the vcetor graphics produced by Illustrator, images in photoshop are built on a grid of pixels. Today we'll discuss the distinction between (and uses of) these two very common two-dimensional data structures used in architectural design .

The number of pixels in one inch determines an image’s resolution. Enlarging/zooming into a pixel-based graphic to a certain extent will produce a jagged and clunky appearance according the image dpi and resolution.

Photoshop Topics We'll Cover

Image Dimension, Size, and Resolution
The number of pixels in one inch determines an image’s resolution, will demonstrate how to edit the resolution or size of an image.
Canvas Size
Edit the artwork space within the file (often used when you are adding numerous images together)
Image Mode
Change from Grayscale to Color. RGB = Red Green Blue, the way a computer defines the color. CMYK = Cyan Magenta Yellow Black, the way a printer defines the color from the computer.
Layer Manager changes the layers of artwork. The order of the layers will change visibility. Layers can be hidden / locked / merged.
Selections and Masks
How to work with only select parts of an image.
Move / Crop / Pan Tools
to work around and select work
help edit and adjust the image. We will explain these more in depth later.

The PhotoMerge Tool

Check out the photomerge workflow for a full discussion of Adobe Photoshop's photo-merging feature.


Students should come together to create a contact list with cell phone numbers. This way, if someone doesn't show up for a review, we will be able to contact them. Often this is because students have overslept, accidently. Also, students should put together funding to purchase a simple First Aid kid (with bandaids) for the upcoming term. Safety first!
