PART 1: IMAGE FORMATS

a)Find out the most common formats for images and write a short description of the features of each of them.

The most common image file formats, the most important for cameras, printing, scanning, and internet use, are JPG, TIF, PNG, and GIF.

• JPG compresses the data to be very much smaller in the file. Digital cameras and web pages normally use it.
• TIF is considered the highest quality format for commercial work. 
• GIF was designed by CompuServe in the early days of computer 8-bit video, before JPG, for video display at dial up modem speeds.
• PNG can replace GIF today (web browsers show both), and PNG also offers many options of TIF too. PNG was invented more recently than the others.

JPG and GIF preserves better the quality.

c) Which formats are more suitable for web design?

JPG and GIF.
