Resizing Photographs Accurately changing the old to new Resizing Counts! • If you resize a picture incorrectly it will be immediately noticed. Need to Shrink • Enlarging photos will likely have poor results. • The picture will end up being blurry or pixilated. 150% Bigger is Better • Reducing the picture size will not alter the quality or clarity. Real Applications • When working in any type of media you will have fixed sizes that a picture needs to fit into. • The customer does not want a poor quality reduction so you need to figure out the exact amount the picture needs to be reduced. Example • My total workspace for the web page is 1024 X 768 pixels. Example Pt 2 • The customer wants three pictures on the side of the page, they need to fit into an area which is 400 X 300 pixels. • One of the pictures we have is currently 900 X 400. • We need a way to accurately reduce this photo. Example Pt 3 • Current Size 900 X 400 • What would the width be if the length was 400? Second Example • We have a picture 800 X 600 • Will it fit into an area of 300 X 275 if we make the width 275? Second Example Cont. • We will use maximum length instead of width. Practice Original 800 X 600 New Length 120 New Width ? 1200 X 900 ? 500 1100 X 800 700 ? 900 X 525 ? 400 700 X 450 350 ? Practice Answers Original 800 X 600 New Length 120 New Width 90 1200 X 900 667 500 1100 X 800 700 509 900 X 525 686 400 700 X 450 350 225 Maximum Area • We have a photo that is 700 X 500 and we have an area on a web page that is 350 X 275. • If we use the length as our first dimension the picture would resize as 350 X 250 • If we use the width as our first dimension the picture would resize as 385 X 275 • The first equation uses all but 25 pixels and the second number is too large, so the size using the maximum amount of area is 350 X 250. Maximum Area Practice • Photo is 600 X 800. The space provided is 525 X 350. • What is the best size to reduce the photo to, using the maximum amount of area? Max area Practice • Using the length it ends up being 525 X 700, which is too large • Using the width the picture would be 263 X 350. This would be the best choice.
