Using Photoshop Version 7
We shoot images in medium-high resolution. I use the SHQ setting on the Olympus, giving me a 2272x1704 image, 2 megabytes, which looks really good in print or projected. The PC120 yields a 1360x1020 image, 1 megabyte, which still looks good printed or projected. These file sizes are too large for Internet use, so I resize them before uploading.
To resize an image, select from the menu Image, then Image Size. Overtype the numbers so the long side is 400 pixes and the short side is 300 pixels.
Alternatively, if an image benefits from cropping, predefine a crop tool size as show in this screenshot, with the width of 5.5 inches and the height of 4.16 inches, resolution 72 pixels per inches. That crop yields an image of 400x300 pixes.
Example: Cropping and Sharpening
Image 2. The same image after the cropping tool shown above.
Image 1 is the original shot of an antheius on a reef in Micronesia. These are quite small fish, fast and hard to photograph.
Example: Sharpening the Cropped Image
The cropped image is a bit soft in focus. The Unsharp Mask enhances the contrast, making the image sharper.
Image 3. Sharpened with the parameters shown in the filter.
