My name is John Ross from The Art of Retouching Studio. In this video I want to clear up the usual common misconceptions about Color Modes, Color Models, Color Profiles, and Color Spaces. Give me a few minutes of your time, and you will no longer be confused by it.

The base cause of this confusion stems from my research in this topic. Half the websites say one thing, and the other half say something else. Rest assured that I am a qualified professional. I’ve done my research, and this is the correct information.

8-Bit vs. 16-Bit - What is the Difference of 8-Bit and 16-Bit Images - Bit Depth and Tonal Range

This video is available with Free For All.
Running Time: 12 minutes

This Digital Fundamentals tutorial is on the difference between editing images in 8-bit color and 16-bit bit depth. While it should be obvious that 16-bit color is twice as good as the 8-bit color, it just doesn't seem that way to the naked eye. This is because humans can only see less than 10 million colors. Since 8-bit already exceeds 16 million colors, why in the world do we need to work in a bit depth that moves us into trillions of colors? Visually, they both look the same, why use the higher resolution?

This very quick Digital Fundamentals tutorial is only a few minutes long, but guarantees you will never work in the 8-bit bit depth again! With two adjustments using

What is the 300 DPI Myth? What are DPI, PPI and LPI? John Ross will explain to you the differences between Dots Per Inch, Pixels Per Inch, and Lines Per Inch. You will learn how to use them to supply images for Print magazines.

In this video we are going to cover a topic that nobody ever talks about. DPI, PPI and LPI. More specifically, dots per inch, pixels per inch and lines per inch. In the magazine and advertising industry, they throw around the acronym DPI all the time. Designers and advertisers keep telling everyone “I need that image at 300 DPI”. However, more often than not, they really mean 300 PPI.

Photoshop Tutorial - JPG vs. RAW File Formats

This video is available Free for Everyone.
Running Time: 6 minutes

This Adobe Photoshop Tutorial Video compares and contrasts the JPG and RAW File Formats. Now that we’ve spent some time delving into the twists and turns of JPGs and RAWs, it’s time for us to show you some differences of the two formats when it comes to editing an actual picture.

You already know by now that because JPGs have a smaller file size, it also means that they can’t handle the same amount of information on colors as much as the RAW file can. This results to banding whenever you zoom in on a JPG photo.

Photoshop Tutorial - What is RAW File Format?

This video is available Free for Everyone.
Running Time: 8 minutes

This Adobe Photoshop Tutorial Video is going into detail about what is so good about the RAW File Format. When you shoot, the picture taken by your DSLR Camera is stored in the RAW File Format, which essentially keeps your image quality exactly as the camera sees it. The Raw file is made up of ones and zeroes that your computer can process. If you know little about the Raw File Format, then you will soon discover why professionals use it... exclusively.

Photoshop Tutorial - What Are JPGs?

This video is available Free for Everyone.
Running Time: 7 minutes

In this digital world we live in, you see the ubiquitous JPEG everywhere—practically all images you can find online are in this format. Short for Joint Photographic Experts Group, JPEG pictures are compressed images that have the .jpg file extension. Basically, JPEGs or JPGs compress images in order to make their file sizes smaller.

The most annoying thing about sending files and pictures online or via email, is to find that your file attachments are too big; and we wouldn’t want that now, would we? Waiting all that time trying to send over files only to have them rejected due to file size…JPGs solve that issue by reducing image file sizes so that they don’t take up too much space, be it in your hard drive or USB or in your camera.

This video is available Free for Everyone.

This is an Adobe Photoshop Video tutorial that explains Color Models, Color Modes, Color Spaces, and Color Profiles. This is one of the modules from the Photoshop Basic 1 Video Course.

Photoshop Tutorial - Tonal Range, Levels and Curves

This video is available Free for Everyone.
Running Time: 10 minutes

This is an Adobe Photoshop Video tutorial that explains Tonal Range, and the difference between Levels and Curves. While each of these topics is technically different, they each work with the same basic principals, so I thought it would be helpful to understand them, if I covered them all at the same time. Before you seriously get started working with RAW Files, you need to understand Tonal Range, and how the different Sliders affect different aspects of the image.
