PSP 8 Apprentice Class

Week6

 

Screen Capture

 

Many Features

 

 

 

Test
1. JPEG permits a greater degree of compression than the GIF alternative, enabling quicker downloading times for larger graphics. And JPEGs appear to retain almost complete image quality for most photographs.
Where special effects such as transparency or animation are desired, or where simple graphics with few colors are used, GIF is essential.. For most complex graphics and nearly all scanned photographs JPG is clearly the superior choice for webpage graphics.
The background of a GIF can be made transparent, so you see the background color of the browser window you're in,a GIF can be interlaced.
Finally, GIFs can also be animated. Poor old JPEGs just have to stand still.

2. JPG should be used only for the final image, any manipulations should be done before applying JPG compression. The reason is that applying JPG multiple times causes extreme loss of quality.
Where 24 bit original material is available and 256 color "indexed" format proves to be inadequate, JPG files often look better than their GIF counterparts which have 2 to 4 times the file

3. To crop an image means to cut away part, to resize means to make the whole image larger or smaller.


4. Anti-aliasing: To take away the rough edges by shading them with gray colors.


5. Always save work periodically because the good old lockup and program closing for errors pops up suddenly and you lose everything you don't have saved.

more in the next level of PSP8
