ARCHITECTURE PHOTOGRAPHY: PRACTICAL TECHNIQUES & TECHNOLOGIES

Many of the challenges involved in capturing spaces realistically can be overcome using High Dynamic Range (HDR) techniques and Tilt-Shift technologies.

  • Tilt-Shift Lenses
    • Remove keystoning & Keeping lines straight
    • Allow you to use movements to make "stitchable" panoramas
    • Reduce wide-angle distortions
    • Help you get into tight spaces
       
  • High Dynamic Range (HDR) techniques
    • Can appear more "realistic" 
    • Better reveal architectural details
    • Improve visibility of lights and darks  
    • Reduce the need for expensive external lighting

There are some negatives to using these techniques and technologies.

  • Tilt-Shift Lenses
    • Prohibitively expensive ($900-$2300) for many
    • Don't have a wide range of uses (no auto-focus)
    • Complex to use... confusing.
    • More moving parts
    • Heavy!
       
  • High Dynamic Range (HDR) techniques
    • Unrealistic if you're not careful
    • Overused
    • Huge file sizes (25MB per exposure
    • Long exposures... opportunity for errors
    • Expensive 3rd party software

 

TILT-SHIFT LENSES (AKA PERSPECTIVE-CONTROL LENS)

WHAT IS A TILT-SHIFT LENS?

What is a tilt-shift lens and what are the benefits?  What we are working with today: a Canon 5D Mark II or 7D and a 17mm Canon TSE.


"The image captured at your camera's digital sensor is in fact just a central rectangular crop of the circular image being captured by your lens (the "imaging circle"). With most lenses this circle is designed to extend just beyond what is needed by the sensor. Shift lenses, by contrast, actually project a much larger imaging circle than is ordinarily required—thereby allowing the photographer to "shift" this imaging circle to selectively capture a given rectangular portion."

Mason Marsh is a Portland, Oregon-based photographer. In this video he shares his techniques for combining multiple images taken with a tilt & shift lens into a single high-resolution panorama.

 

HDR (HIGH DYNAMIC RANGE) PHOTOGRAPHY

WHAT IS "DYNAMIC RANGE?"

Dynamic range, abbreviated DR or DNR, is the ratio between the largest and smallest possible values of a changeable quantity, such as in signals like sound and light.

HDR TOOLS:

LR/Enfuse - http://www.photographers-toolbox.com/products/lrenfuse.php
More subtle... what I use for most of my work.  Fewer options.  Easy and quick.

Photomatix Pro - http://www.hdrsoft.com/ 
More extreme but has a huge following & lots of options.  

HDR Pro (Photoshop Photography Bundle) 
http://blogs.adobe.com/creativecloud/introducing-the-photoshop-photography-program/
It's free with photoshop.  Maybe I should be using this instead?



PERSPECTIVE CONTROL - POLE PHOTOGRAPHY

 

In this video, we introduce the concept of High Dynamic Range and how it is used as a photographic technique.

In this video, we are going back to the basics to explain the concept of a "stop of light", which is probably the most fundamental subject for new photographers to learn.

In this video, we will discuss a technique known as bracketing to broaden the dynamic range of your images.

Before we continue on with tutorials discussing how to capture and produce HDR photographs, it is important to understand when to shoot an HDR bracketed sequence.

In this video, we will talk about improvements in sensor technology and exactly what you are paying for when buying a high-end professional DSLR.

The tilt/shift lenses can be a rather technical set to wrap your head around.  Here's another vid to help you learn a little bit more about what these lenses cand o.
