improvements to technical file
- 1. Vector Vector graphics make an The lines and curves image much sharper and used to make this shape make it smooth more clear. Bitmap images all the way round and look more blurry and you can you cant see where the shape starts or see all the little squares that changes. create the shape the closer you get. The edges and image Bitmap You can see all aren’t smooth. A vector image the squares that are put together can be stretched and made to make the as big as you want without it shape. looking blurry or pixelated unlike a bitmap image which can only be stretched so much. Usually bitmap images are more photographic images and then vector are shapes and lines and text. That’s why when you make text a big size on word or some software it doesn’t blur it looks exactly the same just bigger.
- 2. Resolution are lots of tiny squares of colour and the higher the resolution the better the little squares all add up and blend together to create a picture that looks clear sharp. Where as if the resolution is low the squares of colour will be more In this image we can clearly In this picture we can see noticeable and the image will see the man and his facial the outline of the man and look blurry and un clear. If you feature, the lines on his face what he is doing. However have a high resolution picture and his expression clearly. we can’t see his facial and try to stretch it bigger This is a high resolution features clearly or the lines though it will eventually picture. We can see the on his face. There are two become pixelated because letters on his top clearly even men in the background if we can’t read the full word. but we can only just see your making it to be from the There are two men in the the one to the right original size. So all the background which we can because the resolution is resolution settings are for that see clearly even though they very low so blurs the size not a bigger picture. are far away because of the picture and makes him resolution of the camera. We blend and blur with the can see the expressions on all background. You can only the 4 closest people so this is just tell the man in the blue why people always want top is wearing glasses high resolution cameras to because of how blurry it is. get the best possible picture they can.
- 3. Aspect Ratio is the width and the height of an image. One of the most popular resolutions is widescreen because of the TV’s and how big they have now become, its also becoming more common on newer laptops. Lots of touch screen phones can be turned to the side and the screen will turn to match the way the phone is being held and the aspect ratio stays the same. The screen sizes are all different but the first and last When watching videos on one show the same thing on both screens but look perfect in both ones. This is because the aspect ratio websites like YouTube you can is adjusted to fit each iPad. The first and second one click a button with the option both have a 7” screen but look different because of of full screen. This makes the the width so the aspect ratio of the width is video full screen without different, but the picture in all of them in clear and breaking the aspect ratio. doesn't looked stretched. The screen orientation is changed when the phone is turned to the side but it stays the same and still fits to the screen. The aspect ratio adjusts to the move.
- 4. This is an example of an animated GIF. This picture moves as you can see the two screen shots of the image show that he moves by taking his hat off then putting it back on. Gifs allow an image to move whether it’s a real picture or animation like this one. A JPEG is a format that you can change files from word or excel or other things into to make it a picture. When you scan a picture to a computer you can choose an open to save it as a jpeg so you can send a picture to someone so they can read it exactly how you see it because its just a picture of it. This is an example of someone saving a file as a JPEG so it will be saved as an image. People use the option Tiff file to save their work if they are saving something big or of high quality because a Tiff file is specifically for very large and high quality images. People who are scanning and faxing things usually use Tiff to save it. This is an example of a fax someone has been faxed and opened as a tiff file. There is a lot of information so it might be a big file so this is why this format has been used.
- 5. An EPS file is one of the most versatile file formats and can be used to save text, graphics and images. A file like this would need to be saved as an EPS file. It is a Photoshop file and has many layers of graphics and has the original image file underneath. PSD files are Photoshop files. All work that you save on Photoshop is saved as a PSD unless you change it to another file format. This is because it saves the file as it is in photo shop with all the layers, text, clipping paths and anything you might have done on the document. This is so that it can be saved and nothing will change and the image won’t flatten or change without you knowing. This file is called beach has the .psd at the end because its being saved a s a Photoshop file. People save a file as a PDF sometimes because then they don’t have to worry if the person they are sending it to won’t have the right word processor to open it. These files can be opened with adobe reader which can be downloaded free and shows the file as a picture so people can read it without even have the same programme it was made and saved in. This is a PDF file opened with Adobe Reader.
