Often, we need to combine images side by side for comparison, control versus…positive, a high resolution close up from a larger source image. By combining…two images in a single reference, a reader is able to understand the direct…comparison and appreciate the differences or lack thereof.…If you are following along with me, open up in the Chapter 12 Exercise Files,…ORO_Normal and ORO_Plaq. Here we want a comparison of two images, one a normal…coronary vessel, the other one demonstrating atherosclerotic plaque. These are…two relatively large images, both 5.5 megabytes, and we are going to reduce each…of their sizes prior to combining them.…
We'll first select the normal image. Go to Image > Image Size and we are going…to reduce the Width to 3 centimeters and increase the Resolution at the same…time to 300. In shrinking the image, we are reducing its size, but we are also…increasing the Resolution slightly, so we'll still have an appropriate fineness…of detail for this image. We hit OK and if we double-click on the magnifying…
