After working for many professionals in Marketing, Business Development and Sales, I have found even though these professionals use the computer every day, hardly any of them would have spent the time to understand about the images they use on a day-to-day basis.
I can see that this is fundamental in causing issues when working with them, and I can confidently say it will affect their Sales skills as this knowledge would help them when communicating to potential leads on the internet and e-mail.
I think when you’re at school, the focus is on getting everyone educated in Maths and English, as this is crucial to get ahead in the world. But I think it’s the same with technology and there’s no shying away from the fact you need to learn some techniques.
Which, should include the understanding, of all the extensions on the end of images and what they mean.
Raster images are more common in general, such as jpg, gif, png, and are widely used on the web. They do not scale up optimally – Image must be created/scanned at the desired usage size or more extensive — standard raster programs: photo editing/paint programs such as Photoshop & Paint Shop, GIMP. Once the image is created at a particular dimension, you may not be able to use this image at a larger size without losing quality.
Vector graphics can be scaled and printed at any size without losing quality. It can be written as significant, and at the highest resolution, the printer or the output device allows — standard vector programs: drawing programs such as Illustrator, CorelDraw, Inkscape.
Knowing this information will help when handling documents, and understanding what can and cannot be done with them can help beat time issues on getting projects done.
Please note: if you come across a PDF document they can hold any file extensions, from raster to vector. Which means without exporting the image from adobe reader or writer software you do not know what you are working with.
I hope this helps. It is worthwhile learning this complicated subject and will improve your day-to-day work on the computer tenfold.
