Digital Imagе: The First Steps Toward Professionalism

You will learn about the professions and programs that work with images, as well as get acquainted with the instructor and her professional path. We will also discuss intellectual property and artificial intelligence in the creative industry.

– Acquaintance with the lecturer

– Course description

– Software options for working with digital images

– Intellectual property in the creative industry

– Artificial intelligence

We will provide a detailed explanation of the analog and digital worlds, clearly explaining how they differ from each other.

– Features of the analog world
– The analog path to the digital world
– Features of the digital world

You will learn what a digital image is, and we will discuss the various sources of these images that many encounter in everyday life.

– What is a DI?
– Sources of DI
– Internal generation
– External generation

Cameras have undergone an interesting evolution that you will learn more about in this lecture. We will also help you understand the principles of modern photo and video camera operation.

– Camera obscura and its use in painting
– Methods of image fixation
– Types of modern cameras and their use in the film and photography industries
– Cameras with CCD sensors
– Cameras with CMOS sensors

We will discuss recording formats and the transmission of information from devices in detail. You will gain a better understanding of pixels, image bit depth, color depth, resolution, FPS, and other important concepts for those already working with digital images or just beginning.

– Recording formats
– Light-sensitive elements – pixels
– The impact of pixel size and quantity
– Image bit depth and color depth
– Working bit depth and representational bit depth
– Conversion of digital images with and without loss of quality
– Codecs
– Resolution and FPS

You will learn more about the influence of light on shooting and the characteristics of artificial and natural lighting. We will also discuss the exposure triangle and other influencing factors. Additionally, you will understand that terms like ISO and Depth of Field (DoF) are not as intimidating as they seem.

– Light as a primary factor
– Natural and artificial lighting
– Exposure triangle
– Sensitivity (ISO)
– Depth of Field (DoF) and the influence of aperture
– Focal length of the lens
– Focusing distance

Together, we will dive into the diverse world of image defects. You will learn to distinguish these artifacts and discover how to avoid or, conversely, use them to your advantage. Many artifacts can enhance your creative vision! We will also explain how to differentiate between noise and grain in an image.

– Optical system artifacts of the camera
– Aberrations, flares, ghosting, vignetting
– Artifacts of digital camera sensors
– A group of artifacts caused by the rolling shutter method
– Moiré
– Digital noise ≠ analog grain
– Dead pixels
– Interpolation, blooming, haloing
– Compression artifacts
– Color mixing and blurriness

We will discuss raster and vector digital images. We will explore their advantages and disadvantages, and explain where to best apply raster and vector graphics. We will also cover mixed images.

– Raster digital images
– Vector digital images
– Mixed digital images
– Advantages, disadvantages, and applications

We will examine in detail what digital images consist of and how to use them in image work. We will thoroughly discuss channels and layers and explain in simple terms what each one is responsible for.

– Brightness, saturation, contrast
– Color correction, grading, and image control tools
– Image layers
– Image channels
– Alpha channel
– Metadata

We have created a foundational guide on color management for you. This is one of the most important topics for understanding how to work with digital images.

– Hardware-independent and hardware-dependent color models
– RGB-based color spaces
– CMYK-based color spaces
– Digital image transfer functions: linear, gamma corrections, and logarithmic
– Popular color spaces
– Industry standards (SMPTE standards)
– Academy Color Encoding System (ACES)
