LO3 - Lesson 7 - File Formats
The document discusses different file formats for images, audio, and video. It describes the properties and limitations of various image file formats like JPEG, GIF, and PNG. These file formats differ in features like color depth, compression levels, and file size. The document also explains the concepts of compressed and uncompressed files as well as lossy and lossless compression techniques used to reduce file sizes.
Basic of photo editing
Image editing applications allow users to crop, touch up, and organize digital photos into albums and slideshows, though they typically have fewer filters than professional programs like Photoshop. Cropping removes outer parts to improve framing or change aspect ratios. Resizing and compressing optimize file sizes for intended uses after editing. Correcting and sharpening or softening are global corrections often applied to digital images. Layers, selections, resolution, image size, and color mode are key terms related to editing digital images.
Lesson 1 • Introduction to Photoshop
This document provides an overview of key photography concepts including pixels, megapixels, resolution, color modes, histograms, and preparing images for print in Photoshop. It defines pixels and megapixels, explains how to calculate megapixels from image dimensions. It also outlines the differences between screen and print resolution, RGB and CMYK color modes, and how histograms can be used to analyze image exposure. The goal is for the learner to understand these essential digital photography and editing fundamentals.
Basic principles of photo editing
Raster images use pixels while vector images use mathematical formulas. Common image editing features include selection tools, layers, cropping, cloning, sharpening/softening, saturation, and adjusting contrast and brightness. Photo manipulation differs from simple photo editing by including techniques like erasing elements, adding objects, and changing features to create unrealistic effects.

K to 12 Entrep-Based Photo Editing Learning Module
Technology and Livelihood Education (TLE) is one of the nomenclatures in the implementation of the K to 12 Basic Education Program (BEP) consisting of four components, namely: Agri-Fishery Arts (AFA), Home Economics (HE), Industrial Arts (IA)-0 and Information and Communication Technology (ICT). In this module, the focus is on an ICT mini-course – PHOTO EDITING.
Now that the workforce lags behind in increasing the number of available jobs, the Department of Education is revitalizing its resources to prepare the young minds by honing their skills as graphic designers or the like to gain a competitive edge. Thus, this module aims to provide students with the knowledge, skills, and motivation in the field of photo editing.
In this course, you will be introduced to different learning activities preparing you to be skillful before you take the plunge into the world of work as a photo editor and to feel more confident while providing support where needed.
This module is specifically crafted to focus on Process and Delivery enriched with hands-on activities. Learning procedures are divided into different sections such as: What to Know, What to Process, What to Reflect and Understand and What to Transfer. Examine and perform the suggested tasks to practice developing a sustainable program, prioritizing needs and building vision. So, explore and experience the K to 12 TLE modules and be a step closer to being a photo editor.

2.01 graphic formats
The document discusses graphic file formats and the factors to consider when choosing one. There are many graphic formats that vary in color depth, compression, portability, and whether they support transparency. Color depth determines the number of colors an image can display, from 1-bit to 24-bit. Compression reduces file size, either losslessly by removing redundant data or lossily by altering pixels and degrading quality. Portability refers to how easily files can be opened across systems. Transparency allows parts of an image to be see-through. The best format depends on an image's intended use and priorities like quality, speed, and file size.

Graphic formats
There are many graphic file formats that vary based on factors like color depth, compression, portability, and transparency. Color depth determines the number of colors an image can display, ranging from 1-bit (2 colors) to 24-bit (over 16 million colors). Compression reduces file size, with lossless maintaining quality and lossy decreasing it the more an image is compressed. Portability refers to how easily files can be opened across devices, while transparency allows parts of an image to be see-through. The best format depends on an image's intended use and priorities like quality, speed, and file size.

Technical File Presentation Version 2
Higher resolution images contain more detail, which can be measured by pixel count. Raster images are composed of pixels in a grid, while vector images use mathematical relationships between points and paths. Bitmaps are best for photos needing subtle shading, while vectors are more suited to illustrations. Common file formats include JPEG for photos and GIF/PNG for web use, with different compression levels and capabilities. Optimizing images balances file size and quality for different purposes.
Final use case_scenario_dbh
The document discusses compressing images for mobile media. It begins by explaining the importance of understanding different media formats as a designer. It then discusses organizing assets by creating clear folder structures and file naming conventions. The document demonstrates compressing images using different Photoshop functions like Save As, Save for Web, and Export As while evaluating how the quality and file size changes. It analyzes common image file formats like JPG, PNG and GIF as well as compression techniques for finding the right balance of quality and file size.
Technical Files Presentation
Image resolution refers to the level of detail in an image, measured by pixel count for digital images. Raster images use a grid of pixels that can vary in shade and color, while vector images use mathematical relationships between points and paths. Higher resolutions allow for more detail but require larger file sizes. Common file formats include JPG for photographs and PNG for internet use, with different compression levels and quality tradeoffs.

Raster graphics use pixels that can be manipulated but result in lower quality when stretched. Vector graphics use mathematically based paths and shapes that do not lose quality when manipulated. Common file formats include JPEG for compressing images, TIFF for lossless compression, GIF for animations and logos, and BMP for individual pixel editing. Optimizing images reduces file size and improves viewing but also reduces quality. Proper naming conventions and use of folders helps manage and organize graphic assets.
File types pro forma
This document provides information on different types of digital graphics file formats including raster graphics (made up of pixels), vector graphics (made up of paths and strokes) and the key differences between the two. It then outlines several specific file formats for raster (JPEG, TIFF, GIF, BMP) and vector (PSD, AI, FLA, WMF) graphics and provides details on what each is used for, advantages and disadvantages. The document also discusses topics like compression, image capture methods, optimizing images, file size considerations, naming conventions and asset management.
Fileformats
There are different types of file formats used for different purposes in graphic design work. A common file format is PSD, which is the default format for Photoshop files that allows images to be saved with layers for future editing. Another popular format is JPEG, which compresses file sizes but can reduce image quality when resized. Other formats discussed include GIF, PNG, TIFF, RAW and EPS, each with their own advantages and disadvantages for uses like vector images, photos, animations and printing.
