Photoshop Professor Notes - Volume 4
Colour Corrections and Dynamic Range ...
This is Volume 4 of 5 in my “Photoshop - Beginners to Intermediate” series. I have developed this series over many years of teaching at both the College and University levels in a variety of departments including the Multimedia Program, Graphic Design Program, the Fashion Program, and the Creative Photography Programs both daytime and evening diploma and certificate programs. These courses in Adobe Photoshop (Volumes 1 through 5), start right at the very beginning assuming that the learner has no experience in using the application.
Lecture 1: Understanding Auto Tone, Auto Contrast and Auto Colour
This lecture introduces the basic “Auto” image correction features available in Photoshop and compares and contrasts them with an explanation of what each are doing.
Lecture 2: The Colour Balance Feature and Hue/Saturation
There are many ways, methods and features in photoshop that allow you to change colours in your image. In this lecture we discuss two of the most commonly used approaches and in using them as adjustment layers, we can always go back and make any changes we feel are necessary.
Lecture 3: Using Photo Filters
This approach to changing colours is one of the forgotten methods. Using actual Photo Filters over a camera’s lens was one of the only ways film photographers could change colours in their images with out getting into the colour darkroom. Not many went into a colour darkroom and left that task to the darkroom technicians.
Also, using these filters over a lens affected the entire image whereas in Photoshop with the use of Adjustment layers, we can affect certain ares of our image and leave the rest unchanged.
Lecture 4: Using Levels, Colour Balance and Hue/Saturation
In this lecture we use a variety of approaches on images to make colour changes to our images in order to enhance them so the look more like what our mind’s eye saw when we first thought about taking the image in the first place.
Lecture 5: Using Levels to Adjust Mid-Tones
This lecture adds to all of the previous methods and techniques discussed. Adjusting the mid-tones to either lighten or darken the individual red, green or blue channels or components of an image can make some amazing results.
This lecture introduces the basic Auto features available in Photoshop and compares them with an explanation of what they are doing.
The color balance feature is discussed in detail as well as the Hue / Saturation dialog box.
The Photo Filters option is often over looked or not completely understood but in this lecture this feature will be explained.
Using Levels, Color Balance and Hue/Saturation to correct a family portrait In this lecture I show how I would fix a family portrait that is too dar, has a colour problem and is over saturated in a specific area.
This lecture introduces the concept of tone matching images and prepares the image for the next section on retouching and repairing images.
John's background is in photography. He was first introduced to photography way back in highschool and has been developing film and making prints ever since. He has had a variety of jobs in the photographic industry ranging from motion picture lab technician to portraits & weddings to commercial studio work to medical photography lab technician to newspaper photographer and most recently shooting virtual tours and panoramic images.
John first started teaching, actually the unofficial teaching assistant, at the School of Modern Photography in Montreal back in the early 70's when he himself was still a student. The lead instructor recognized John's ability to explain photographic principals and lighting techniques to other students and asked him to participate as the unofficial teaching assistant. The same thing more or less happened when he studied at Dawson College years later.
When John moved to Toronto in the early 80's, he found employment with a portrait studio company and when he completed his training and probation period he became the new West Toronto Photography Trainer. He also helped develop the corporate training policies & procedures for that company's North American operation.
After working for the Metroland Group of Community Newspapers as a photographer for over 8 years, John began teaching at Humber College and in 2003 he recieved the Digital Imaging Training Centre's "Teacher of the Year" award. In 2005, John was the first ever recipient of the Dean Collins Photoshop Educator Scholarship Award presented by Scott Kelby, President of the National Association of Photoshop Professionals (NAPP), at the PhotoshopWorld Convention in Boston September 2005.</p>
