#2) Inside the red circle marked #2 is the zoom factor. I recommend you set this to 200%, which doubles the viewing size (it does not change the actual size, were only zooming), so at the end of step #5, we can scroll around and verify the quality is acceptable. If we scroll MORE than 200% were going to see things that are just not visible in normal viewing mode and therefore irrelevant. On around the counter-clockwise circle.#3) Click the 2-UP tab. 2-up is not a soft drink or ghetto talk (I just could NOT think of anything funnier to put there. Sorry), it just allows us to do a side-by-side comparison between our newly optimized version and our original photograph. See, step 3 was duck soup, a piece of cake, a walk in the park; getting carried away again...#4) Set the #4 box to JPEG. JPEG was made for photographs, actually thats what the P in JPEG stands for, photographic. If you are doing line drawings or illustrations, JPEG is not the best choice. We photographers have a compression format thats our very own. Awww.
