Chapter 1A b r i e f h i s t o r yHistory ofPhotographyPhotography stands today as one of the most influential visual technologies inhuman history. Its invention radically transformed how societies documentedreality, preserved cultural memory, and communicated ideas. From earlyexperiments with light-sensitive chemicals to the digital and AI-driven systems oftoday, photography’s journey reflects the evolution of human curiosity, creativity,and communication.This chapter explores the historical origins of photography, the needs it wascreated to fulfil, the functions it serves across various contexts, and thedevelopment from black and white imaging to colour photography as a powerfulvisual communication medium.
Photography is far more than the act of pressing a shutter button. It represents asophisticated visual communication system that emerged from humanity’s needto record, interpret, and understand the world. Since its invention in the 19thcentury, photography has quickly evolved into a vital medium for historicaldocumentation, scientific inquiry, mass communication, creative expression,cultural preservation, and personal memory. Its existence is rooted in a universalhuman desire to freeze time, preserve experiences, and bring home visualevidence of realities that words alone often struggle to describe. Thedevelopment of photography is thus a reflection of how humans continuouslyseek better tools to see, remember, and share their experiences.Recognize the need & functionsof the existence of photographyChapter 1
Portrait photography emerged as one of the earliest and most influentialapplications of photographic technology. Prior to the invention of the camera, thecreation of portraits relied heavily on painting a process that was expensive,labour intensive, and accessible only to the wealthy. With the introduction ofphotography in the 19th century, portraiture became significantly moredemocratized, allowing a much wider segment of society to document theirlikeness affordably and efficiently. This shift marked an important culturaltransformation, positioning photography as a medium that preserves identity,memory, and social history.Portrait photography serves several key functions. It enables identity preservationby providing individuals with visual records of their physical appearance atmoments in life, forming valuable personal and familial archives. Portraits alsocontribute to social documentation by capturing details such as fashion trends,cultural practices, hairstyles, and accessories that define specific eras.Additionally, portraits express emotional depth conveying personality, mood, andpsychological states through facial expressions, gestures, and posture. Beyondpersonal value, portrait photography plays a significant role in cultural memory bypreserving images of leaders, communities, and marginalized groups who mayotherwise be overlooked in written historical accounts. As early processes likedaguerreotypes and later studio-based photography became more accessible,portraiture evolved into a widespread cultural practice, highlighting the medium’simportance in self-representation and collective memory.Chapter 1The plenitude of PotraitsSTUDIO LIGHT PORTRAITUREF2.8 | 100s | 50mmSony Alpha A7iiiSyakir Saidin
The plenitude of portraits today reflects the versatility and enduring relevance ofthe genre. Portrait photography exists in multiple forms, each serving distinctcommunicative and aesthetic purposes.Formal portraits often utilize controlled lighting and composed poses, typicallyproduced in studio environments for official or family records.Candid portraits capture unplanned, spontaneous moments that revealauthenticity and natural emotion.Environmental portraits situate subjects within meaningful settings such asworkplaces, homes, or cultural spaces providing added context to theiridentity and lifestyle.Self-portraits, an early practice adopted by photographers themselves, haveevolved into the globally widespread phenomenon of modern-day selfies,further emphasizing photography’s role in personal expression.Through these varied forms, portrait photography continues to shape howindividuals and societies represent themselves, remember the past, andcommunicate identity.Chapter 1The plenitude of PotraitsA MAN PLAY GUITARF2.8 | 150s | 50mmiNikon D60Razif Mustapha

Architectural photography, meanwhile, plays a crucial role in chroniclingbuildings, monuments, and structural designs across different eras. Throughcareful attention to geometry, perspective, and spatial composition,photographers document the evolution of architectural styles, constructiontechniques, and cultural identities embodied in built environments.Such images aid architects, historians, and researchers in studying thedevelopment of cities, heritage sites, and iconic structures. They also supportpreservation efforts by providing accurate visual records of buildings that mayundergo renovation, deterioration, or complete disappearance over time.PUTRAJAYA BRIDGE 2025Hani Qistina | DRG1B | Sem 1 Session 1: 2025/2026Chapter 1Documentation of Landscapeand Architecture
Historically, both genres have produced influential works. Photographers likeAnsel Adams documented the grandeur of American national parks, contributingto environmental conservation movements. Architectural photographers havecaptured world-famous structures such as the Eiffel Tower, ancient temples, andheritage buildings, offering scholars valuable visual data to analyse structuralchanges and cultural significance. Together, landscape and architecturalphotography form an important visual archive that strengthens our understandingof the relationship between humans, nature, and the built world.This image, reminiscent of Ansel Adams' iconic work, captures a breathtakingnatural landscape in monochrome, highlighting the dramatic interplay of lightand shadow, and the majestic scale of nature. It perfectly illustrates howlandscape photography preserves the visual information of natural environmentsand contributes to environmental awareness.The Ansel Adams Publishing Right TrustCourtesy of Museum of Fine Arts, BostonChapter 1Documentation of Landscapeand Architecture

Photography plays a crucial role in recording both the material culture of societyand the significant events that shape human experience. The documentation ofobjects includes the systematic photographing of artefacts, artworks, scientificspecimens, machinery, and commercial products. These visual records supportcataloguing processes, facilitate academic research, assist conservation work, andserve as essential resources in journalism and advertising.This image depicts a professional meticulously photographing an ornate, antiqueclock in a studio setting. This type of systematic photography is crucial forcataloguing museum artifacts, assisting conservationists in monitoring an object'scondition over time, and providing detailed visual records for academic researchor exhibitions.Chapter 1Documentation of Objects andEventsMuseum artefact visualdocumentation
In parallel, the documentation of events serves as an essential visual archive thatanchors historical understanding. Photographs of political activities, socialmovements, public ceremonies, natural disasters, and periods of conflict provideauthentic, unfiltered accounts that help societies interpret both past andcontemporary realities. These images function not only as reference points forhistorians and researchers, but also as evidence that shapes public awarenessand collective memory.Beyond their historical significance, documentary photographs carry substantialvalue in professional fields that rely on factual accuracy. In investigativejournalism, they support the verification of claims and strengthen narrativecredibility; in forensic science and legal contexts, detailed and accuratelycaptured imagery plays a critical role in analysis, case reconstruction, and judicialinterpretation. At the personal and cultural level, event documentation preservescherished memories of celebrations, rituals, and important milestones. Thesephotographs safeguard emotional and cultural heritage, ensuring that keyexperiences and traditions are remembered, appreciated, and transmitted acrossgenerations.Malaysian Funfair 2025VIVO X100 UltraSyakir Saidin
Furthermore, the visual documentation of objects and events enhancescommunication within educational materials, research reports, exhibitions, andmedia publications, providing clarity and context that written descriptions alonecannot achieve. Through these diverse functions, photography remains anessential medium for preserving knowledge, supporting analysis, andcommunicating the richness of the human story.Ultimately, documentation of objects and events bridges the gap betweenobservation and historical continuity. It provides visual proof that supportsresearch, education, cultural preservation, and informed decision-making. Bymastering both the technical and ethical dimensions of this practice,photographers contribute to a global repository of knowledge ensuring thatimportant objects, moments, and narratives are preserved with accuracy andcredibility for future generations.Malaysian Independence Day 2025
IntroductionPhotography, since its inception, has transcended mere technical mechanism; ithas evolved into a complex system of visual communication, fulfilling humanity'score need to record, interpret, and understand the world. The development of thismedium reflects a universal desire to freeze time and convey realities that wordsoften struggle to articulate. This chapter will critically analyze the transformativeshift from the dominating world of black and white (monochrome) to the masteryof color (chromatic) that defines contemporary visual communication.Chapter 1The Transformation fromMonochrome to Chromatic :Photography as a Medium ofVisual CommunicationHistory of photographyPhotography traces its origins to the early 19th century, beginning with black andwhite images produced through pioneering chemical processes such as thedaguerreotype and calotype. These early techniques relied heavily on theinteraction of light and shadow, establishing the foundations of visualcomposition and influencing both documentary and artistic practices for decadesto come. As photographic technology continued to evolve, film becameincreasingly sensitive, reliable, and accessible, paving the way for the emergenceof color photography in the 1930s.The introduction of Kodachrome marked a major breakthrough in visualcommunication, enabling photographers to record vibrant, true-to-life colors thattransformed storytelling in journalism, advertising, cultural documentation, andpersonal archives. This shift not only broadened creative possibilities but alsodeepened the emotional resonance of photographic imagery. In thecontemporary era, digital photography has further expanded these capabilitieswith precise color management, advanced sensor technology, and instantaneousimage production making photography more versatile, efficient, and globallyaccessible than ever before.
From Black and White to ColourChapter 1The Transformation fromMonochrome to Chromatic :Photography as a Medium ofVisual Communication
Straight image of photographyStraight Image Photography refers to photographs presented as accurately andnaturally as possible, with minimal manipulation. The intention is to preserve theintegrity of the real-world scene as observed by the camera.Chapter 1The Transformation fromMonochrome to Chromatic :Photography as a Medium ofVisual CommunicationKuala Perlis 2025Canon EOS 7D Mark IIIf/3.2 | 1/1000 sec | ISO 100| 70 mmRazif Mustapha
The Core Principles of Straight PhotographyThe concept of straight photography is an aesthetic doctrine that emphasizesclarity, sharpness, and an unadorned representation of reality. It emerged in theearly 20th century as a firm reaction against Pictorialism, a style that sought tomimic painting through heavy manipulation and soft focus.Sharp focus & high detailThe image must be crisp, clear, and show the true texture of the subject. Nointentional artistic blur is used.Minimal editing / manipulationOnly basic adjustments such as exposure or contrast are applied not alteringshapes, adding elements, or manipulating reality.Emphasis on realityThe photograph presents the world as the human eye sees it. The goal ishonest and “pure” documentation.Direct, clean compositionThe composition is straightforward no excessive drama, no gimmicks, justclear visual presentation.Use of natural or realistic lightingLighting is used to preserve the subject’s true mood, without creating overlystylized or artificial atmospheres.Chapter 1The Transformation fromMonochrome to Chromatic :Photography as a Medium ofVisual Communication

The Communicative Function of Straight ImagesThis emphasis on visual honesty established the ethical foundation of themedium. The straight image was crucial in cementing photography's function indocumentation, forensic science, and investigative journalism its legitimacy reliedon the assumption of non-manipulation. Consequently, straight images serve asessential visual archives, providing the purest and most detailed visual data forhistorians, architects, and environmental researchers, thus reinforcing thecamera's role as an objective witness. emphasizes sharp focus, detailed rendering,and unmanipulated imagery.Chapter 1The Transformation fromMonochrome to Chromatic :Photography as a Medium ofVisual Communication
Photo manipulationPhoto manipulation is one of the most significant and sometimes controversialdevelopments in photography. In the early days of analog photography,manipulation was done entirely in the darkroom using physical methods.Techniques such as dodging and burning allowed photographers to lighten ordarken selected areas to improve mood or contrast. More complex approaches,like composite printing, combined several negatives to create a singleconstructed scene. Photographers also performed manual retouching with dyes,airbrushing, or scratching to enhance facial features or perfect the appearance ofsubjects, especially in portrait and commercial work.With the arrival of digital photography and editing software like AdobePhotoshop, manipulation became far easier, faster, and more precise. Digital toolsmade it possible to remove objects, blend multiple images, change colours, andeven create visuals that do not exist in real life. These new capabilities greatlyexpanded creative possibilities in advertising, design, and fine art.However, digital manipulation also raises ethical concerns. In fields such asphotojournalism and documentary photography, altering an image can misleadaudiences and damage trust. For this reason, strict rules exist to ensure thatimages used in news or factual reporting remain accurate and unaltered.Chapter 1The Transformation fromMonochrome to Chromatic :Photography as a Medium ofVisual Communication

Overall, understanding photo manipulation involves recognising both itscreative potential and its ethical implications. A manipulated image mayfunction as artistic expression or visual storytelling, but it must be clearlydistinguished from photographs intended to document reality truthfully.Uses darkroom techniques or digital tools to alter images creatively. From earlycomposite prints to modern Photoshop artistry, manipulation exploresphotography's potential beyond pure documentation.SummaryPhotography has grown from simple black-and-white images to modern colourand digital photography, changing how we record and communicate visualinformation. Early photography focused on showing the world as accurately aspossible, known as straight photography, which is important for journalism,science, and documentation.Over time, technology improved from early cameras to film, and then to digitalsystems making photographs clearer, faster to produce, and more expressive.This development strengthened photography’s role in education, culture, andcommunication.At the same time, photo manipulation became an important part ofphotography. In the past, editing was done in the darkroom through dodging,burning, or combining negatives. Today, digital tools like Photoshop allowmuch more advanced editing, from simple touch-ups to fully constructedimages.Because of this, photography now has two sides:Accurate documentation, where images must remain truthful.Creative manipulation, where images can be changed for artistic orcommercial purposes.Understanding these differences helps viewers interpret photographs morecritically recognizing whether an image is a factual record or a creativeinterpretation.Chapter 1

Photography has entered a transformative era where innovation drivesevery stage of image creation. Once dependent solely on mechanicalprecision and chemical processes, the medium now thrives on digitalecosystems powered by advanced sensors, computational imaging,artificial intelligence, and seamless connectivity. These emergingtechnologies have not only enhanced the technical quality ofphotographs but have also redefined how images are captured,manipulated, stored, and shared across global platforms.Today’s photographers operate in an environment where traditional skillsintersect with digital fluency. High-performance cameras, intelligentediting software, cloud-based workflows, and smartphone photographyhave democratized image-making, giving creators unprecedented controland creative freedom. At the same time, these advancements raise newconversations about authenticity, ethics, automation, and the evolvingrole of the photographer.This chapter provides a comprehensive overview of how newtechnologies continue to shape photographic practice. By understandingthese developments, learners and practitioners can better appreciate theopportunities and challenges of modern photography—and leveragethese tools to produce impactful and meaningful visual work.Chapter 2Photography and NewTechnology
Conventional photography relies on a fascinating interplay of optics, chemistry,and mechanics. The journey from a fleeting moment to a tangible photographinvolves several key stages, each perfected over decades of innovation.Conventional Photography: Technologyand Basic ProcessesAt the core of conventional photography is the camera, a light-tight boxdesigned to precisely control how light interacts with the film. While designsvary greatly, all cameras share fundamental components.Camera Body: This is the main enclosure that houses all the internalmechanisms and protects the film from unwanted light.Lens: Arguably the most critical part, the lens gathers light from the sceneand focuses it onto the film. Lenses are complex optical systems, oftencomposed of multiple glass elements to correct for various aberrations andcreate sharp images. The focal length of a lens (e.g., 50mm, 200mm)determines its angle of view and magnification.The Shutter: The shutter is a mechanical device that controls the durationfor which light exposes the film. Shutter speeds are measured in fractions ofa second (e.g., 1/60th, 1/250th, 1/1000th) or full seconds. A faster shutterspeed freezes motion, while a slower shutter speed allows for motion blur.Aperture (Diaphragm): The Aperture: Located within the lens, the aperture isan adjustable opening that controls the amount of light passing through tothe film. It's often described in \"f-stops\" (e.g., f/2.8, f/8, f/16). A wider aperture(smaller f-number) lets in more light, creating a shallower depth of field(more background blur). A narrower aperture (larger f-number) lets in lesslight, resulting in a greater depth of field (more in focus).Parts ofthe CameraChapter 2
Film is the heart ofconventionalphotography, the mediumthat records the image. It'sa marvel of chemicalengineering, consisting ofseveral layers, eachplaying a crucial role.FilmChapter 2
The Base: This is the support layer, typically made of transparent plastic (cellulosetriacetate or polyester). It provides structural integrity to the film.The Emulsion Layer: This is the most critical layer, containing light-sensitive silverhalide crystals (silver bromide, silver chloride, silver iodide) suspended in gelatin.When these crystals are exposed to light, they undergo a chemical change,forming a \"latent image\" – an invisible record of the light pattern.Anti-Halation Layer: Located beneath the emulsion or on the back of the film, thislayer absorbs light that passes through the emulsion, preventing it from reflectingand causing halos or blurring around bright areas.Protective Layer: A thin, clear layer on top of the emulsion protects it fromscratches and abrasions.Film Speed (ISO): Film speed, or ISO, indicates the film's sensitivity to light. Ahigher ISO film (e.g., ISO 800) is more sensitive to light and can be used in darkerconditions or with faster shutter speeds but often produces more \"grain\" (visiblespecks in the image). A lower ISO film (e.g., ISO 100) requires lighter but producesfiner grain and better detail.Types of Film:Black and White Film: Contains a single layer of silver halide crystals that reactto all visible light.Color Negative Film: Contains three separate emulsion layers, each sensitiveto a different primary color of light (red, green, blue). During development,these layers produce complementary colored dyes. The final negative imagehas colors reversed from the original scene.Color Reversal Film (Slide Film or Transparency Film): Also has three colorsensitive layers, but it's processed to produce a positive image directly on thefilm, suitable for projection or viewing.Chapter 2
Recognize film development and printing processThe true magic of conventional photography unfolds in the darkroom, where theinvisible latent image on the exposed film is transformed into a visible negative,and then into a positive print. This process is a careful dance of chemistry andtiming.Film Development (Processing the Negative)This entire process must be done in complete darkness (for black and white film)or with specific safelights (for color film, depending on the process).Loading the Film : The exposed film is carefully loaded onto a developing reeland placed inside a light-tight developing tank. This ensures that chemicalscan circulate evenly over the film.Developer : The developer solution converts the exposed silver halide crystalsinto metallic silver, forming the visible image. The time, temperature, andagitation during this step are crucial for controlling the contrast and density ofthe negative.Stop Bath : A dilute acid solution (often acetic acid) is used to halt the action ofthe developer, preventing over-development.Fixer : The fixer (usually sodium thiosulfate) dissolves away the unexposedsilver halide crystals, making the image permanent and no longer sensitive tolight. Without fixing, the negative would eventually darken completely.Washing : The film is thoroughly washed in running water to remove allresidual chemicals. This is vital for the long-term archival stability of thenegative.Wetting Agent/Drying : A wetting agent (like Photo-Flo) is often used toprevent water spots, and then the film is hung to dry in a dust-freeenvironment.`Chapter 2
Chapter 2
Chapter 2
Printing Process (Making a Positive from the Negative)Once the negative is dry, it can be used to create positive prints. This also takesplace in a darkroom, under specific safelight conditions for black and whiteprinting.Enlarger: An enlarger is a specialized projector that shines light through thenegative and focuses it onto light-sensitive photographic paper. It allowscontrol over the size of the print and fine-tuning of focus.Photographic Paper: Paper coated with a light-sensitive emulsion.Exposure: The negative is placed in the enlarger, and light is shone through itonto the paper for a specific duration.Paper Development: The exposed paper undergoes a similar chemicalprocess (developer, stop bath, fixer, wash) to reveal the final positive print.Chapter 2
Chapter 2
Recognize health and safety protocol in the darkroom.Working in a darkroom involves handling chemicals and operating electricalequipment in subdued lighting conditions. Therefore, adhering to strict healthand safety protocols is paramount to prevent accidents, chemical exposure, andensure a safe working environment.Chemical Handling and StorageThe chemicals used in photography can be irritants, sensitizers, or even corrosiveif handled improperly.Gloves and Eye Protection: Always wear chemical-resistant gloves (nitrile isrecommended) and safety goggles or glasses when mixing, pouring, orprocessing with chemicals. This prevents skin contact and eye splashes.Ventilation: Ensure the darkroom is well-ventilated, ideally with an exhaust fan,to remove chemical fumes. Some chemicals, especially fixer and certaindevelopers, can produce strong odours and irritating vapours.Proper Labelling: All chemical containers must be clearly labelled with theircontents, concentration, and any relevant hazard warnings. Never useunmarked containers.Chapter 2

Functions and features of digital photography technologyDigital photography has revolutionized how we capture and share images,offering instant feedback, immense storage capacity, and unparalleled flexibility.At its core, digital photography replaces film with an electronic sensor thatconverts light into digital data. This data is then processed by the camera'sinternal computer and stored as a digital file (like JPEG or RAW) on a memory card.Key functions and features common to most digital camerasincludeImage Sensor: The silicon chip that captures light and converts it intoelectrical signals. The size and resolution (megapixels) of the sensorsignificantly impact image quality.Camera Sensor Size Comparison ChartChapter 2
Image ProcessorThe camera's \"brain\" that takes the raw data from the sensor and processes it intoa viewable image, applying color, contrast, sharpening, and noise reduction.Memory Card Slot: For storing the digital image filesChapter 2
