How to Resize Images Basics
You have taken some great pictures and now you want to share them. You can email, put on a website, add to a document, upload to an online photo album or burn to disk. As you get ready to one of these things you hit a major problem, the pictures are too big and need to be resized with an image resizer but how do you do that?
The images need to be resized an image resizer, the next step is to learn how to resize pictures.
The following article will guide you through the basic steps to learn how to resize images. This involves 3 basic things, the right height, width and quality of the image, if you set these three things correctly, you will resize images properly every time.
Need to know basic terminology:
Medium
(Plural media) are the print (newspaper, magazines, etc.) and electronic (email, website) communication devices used for sharing information.
Height
How high your image is.
Width
How wide your image is.
Quality
In laymen terms image quality is how much detail is in the image, the lower the quality the less detail there is, if the quality is too low then the image looks blocky, if the quality is too high then the file size grows and this really matters if you are emailing or showing the image on the web.
Quality of an image in a document printed out should always be higher than the quality of one being viewed on the internet as when a image is printed out it needs higher quality than an image that you view on your computer.
Aspect Ratio
Easiest way to explain aspect ratio is to say that it means the ratio between the width of the picture and the height of the picture. When you resize a picture you need to ensure to calculate the aspect ratio of the new size to ensure the picture is not stretched or skewed. Most resize tools such as Picture Resize will do this for you.
Every medium such as email, websites and online photo galleries show pictures differently, each one need their pictures resized to different heights widths and quality.
The problems that you will face are; pictures hare too big, too small, appear stretched or skewed or appear blocky and may even have bits missing here and there, these are all signs of an image not being resized properly to fit the medium they are on.
Images are too big:
If the pictures are too big then the Height and width of the image is too large.
Blocky looking pictures
Height and width too small on the image
Or the quality is too low.
Images appear stretched or skewed.
This has the affect of like looking into a fun mirror at a carnival, things either appear too tall or too short and too wide. The reason for this is because the aspect ratio has been compromised
These are all symptoms of images being resized incorrectly, they need to be resized properly for the medium they are appearing on.
