Photoshop Professor Notes - Volume 3
Understanding Layers ...
This is Volume 3 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.
As a fundamental concept of Photoshop since version 3 (not CS3 but version 3), Layers are probably one of the most flexible ways to work in Photoshop as far as editing our images is concerned.
Lecture 1: Let’s look at some Layers - An Overview of Layers
If you don’t already know what Layers are in Photoshop, this lecture will enlighten you to the fact that Layers are an integral part of any photoshop image and are used extensively in creating collages, montages and in scrapbooking projects. For example, if you wanted to type some text in your image, such as “Happy Birthday” or “Congratulations”, you would do this on a separate layer from the image itself.
Lecture 2: An In-depth look at Layers
In this lecture we explain what the different kinds of layer there are in Photoshop. As mentioned in Lecture 1, there are Type Layers as well as Adjustment Layers. Along with Adjustment Layers come Layer Masks. Layer masks help you hide portions of a layer.
Lecture 3: Creating New Layers
As with anything in Photoshop, there are approximately half a dozen ways to do something as this goes for getting new Layers into your image. Depending on what you are working on, you’ll want to choose one of the many ways there are to get that new layer into your image file.
Lecture 4: Drag ’n Drop and Copy ‘n Paste Layer Contents
These are two methods used to bring parts of other images into your main image. They both have their pros and cons and understanding which method to use with the task at hand is really important. You’ll learn all of the ins and outs here.
Lecture 5: Layer Groups
When you are working on a project that includes many layers in your image file, things can get a bit messy and disorganized but with Layer Groups we can keep a handle on this.
Lecture 6: Adjustment Layers
Since you already kind of understand what Layers in Photoshop are, then moving on to adjustable layers should be a smooth transition. If you performed an adjustment to a normal layer and for example say you made a change to lighten the image using Levels, then these adjustments would be permanent because you made the adjustment to the actual pixels in that layer. If you used Adjustment Layers, which are basically mathematical calculations floating above your image, then you could go back and make more changes for as many times as you wish. Nothing is permanent with Adjustment Layers.
Lecture 7: layer Styles
Layer Styles are the cool effects that you can apply to aspects of your image. say for example you did create that text I mentioned earlier, “Happy Birthday”. Well with Layer Styles you could add a drop shadow and a stroke to that text. There are others that can be applied as well and ... just like so many other things in Photoshop, these layer Styles are completely editable forever and a day.
Lecture 8: Layer Masks
Layer Masks are very very cool. They offer a way to hide and show portions of a layer or for that matter a complete layer. All adjustment layers come with white layer masks by default. You paint with black on that Layer Mask to hide portions. Unlike using the Eraser tool which permanently removes the pixels, painting with black on layer masks only temporarily hides those pixels because you can just as easily paint back over that area with white to reveal those pixels again.
Lecture 9: Layer Opacity and Fill Settings
Learning the differences between these two settings will make a large difference in your approach to designing your layouts in Photoshop. When I ask students if they know the difference between the two or to explain the differences, they go blank. It’s not difficult and once explained, it makes perfect sense. This is one of those topics that is better explained visually than with words.
In this lecture we discuss the various aspects of layers and the Layers Panel.
This lecture explains the concepts of Layers in depth using two different image files, each containing numerous layers which assist me in this explanation.
This lecture covers all of the many and various ways to create new layers.
Drag-n-Drop is probably one of the fastest methods of getting your images form one file to another. Here I show some of the secrets of doing this efficiently and precisely.
Layer Management is covered in this lecture. Taking control of your layers panel can take the headache out the dozens of layers you may end up with.
Adjustment Layers are another non-destructive feature in Photoshop allowing you to re-edit your adjustments forever and a day.
Layer Styles can "save the day" as they say and add creativity to your projects. They allow you to choose how effects on one layer combine with another.
Layer masks are a non-destructive way of concealing parts of a layer - very cool!
Understanding the difference between layer Opacity and Layer Fill is often over looked by many. In this lecture I explain how they work.
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>
