Types of digital capture and digital image types.

way s to image capture and why people use each. Digital cameras photo scanners are the main ways of image capture and generally you would use a photo scanner to try and copy a real life drawing or photo to digital this can be for many reasons including for easier use as reference when 3d modeling so you can zoom in on certain details or to move the image into a photo editing program to do things like remaster it in higher resolution or to experiment with to try new things without messing with the original there are cons to this though as scans dont always look as good as the real thing but can still be handy in the ways i've described. Meanwhile digital cameras are by far the most common way of image capture coming in all sorts of shapes sizes and pupuse from cheap £20 holiday cameras which don't do great photos but good for the price to cameras on mobile phones to the latest and greatest high end cameras going into the £1000s and there is many ways these can and will be used from snapping photos of people and animals to landscapes to using camera photos for textures or for architecture where you use a digital CAD model of a building and photoshopping it in to a photo to give a idea on how the building will look. They can be used for analysing data by capturing things the human eye may miss good example of this is the famous running horse photos which were used to figure out how they ran. In games development the main ways they are used is for textures for scouting places and environments to aid with modeling and a technology which is being used more and more called photogrammetry which can be used to create 3d models from photos by taking sometimes 100s to 1000s of photos of buildings people objects etc from different angles and importing them into a package like autodesk recap 360 which turns of the photos into models. In games development its best to use as high resolution photos as possible to all the detail you can though when texturing is best to lower the resolution so you don't have too many high res textures as this will use a lot more VRAM on your GPU Graphics Processing Unit. there are 2 main types of digital graphics in modern computing this may teh first is bitmap images which is the most common type and are used for most final works for textures etc andare normally saved in formats like PNG JPEG etc this images are a set image size so for example 1000 pixels by 1000 pixels this is fine for downscaling as there is not too many problems but does not scale up well at all normally making it pixelated. The 2nd type is vector image this is the type software like photoshop use and the main file types you see these in are things like .pdf and .ai. Vector images give you the best quality and infernate scalability with no pixelation and can be easily exported as a bitmap image for use in other applications once finished.

The use of digital graphics in video games.

There are mainly uses for digital 2d graphics in video games from 2d games to 3dgames textures and there are many styles and ways to do this. The main use in 3dgames is for texturing objects and makings things like sky boxes and menus and HUDS. when creating 3d models you nomaly want to texture them so you make uv maps of them model and import that into photo editing software like photoshop. You can also create textures for 2d and 3d games by making 3d models and burning the 3d model into a 2d texture this is a good way of making 3d looking brick walls etc while keeping it 2d and less demanding. One thing you must always take into account is making sure you dont make your files too big or too demanding on the final product it is useful to compress files when saving to cut down on files sizes or save them in a lower resolution otherwise your game will be extremely demanding on pc hardware for no good reason.

Video game developers also use 2d digital graphics editing programs like photoshop with drawing tablets or just there mouse and keyboard to draw concept art of games instead or in conjunction with hand drawn physical artwork this can be extremely handy as mentioned earlier for editing and making changes without destroying the original copy so you can try different styles or correct mistakes etc.

Some art styles used for digital graphics in video games

Firstly there is photorealism this style when it comes to 2d is mainly for texture work and for the concept art of photorealistic 3d video games. This style has a long history however photorealism is less of a style and more a goal as its has been nearly impossible to recreate photorealistic graphics in video games so the style more refrese to games that try to aim for this without exaggeration reality this is often seen in simulator games or “walkingsimulators” as the genre of story based game with little playing imput have become know like the game Everybody's Gone to the Rapture which tries to accurately recreate a british village to immerse the player in the game world.

Stylised realism this is one of the most common styles of games in the modern aaa scene from GTA 5 to Forza 7 to Battlefield these are hyper detailed games which aim for realism in many ways but will try and make the game look more appealing by having over exaggerated colours and post processing effects while still looking somewhat photoreal in some ways. This style helps devs get over the problems of modern tech when trying to create realistic looking games as even the most powerfull cpus and gpus struggle to do full Photorealism plus the style is made the make games look more like modern movies with colour palette and mood etc.
