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 1200 X 900 1100 X 800 900 X 525 700 X 450 New Length 120 ? 700 ? 350 New Width ? 500 ? 400 ?
Practice Answers Original 800 X 600 1200 X 900 1100 X 800 900 X 525 700 X 450 New Length 120 667 700 686 350 New Width 90 500 509 400 225
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.
