Intro to Digital Photography Course

Week 1 - Page 4


Notes: (This page takes 36 sec to load at 28.8 baud.) On this page, I took one of my spider web photos that was a little fuzzy and tried to sharpen it up without distorting the details of the photo. On these examples, I did use jpg compression, because that is what I would normally do prior to uploading a photo to the web. The exercise is to refine a blurry photo for use, without ruining it.
1600 x 1200 This is the original photo. The white box shows the area that I cropped out of it for experimentation purposes.	800 x 600 This is the cropped section. I did not want to reduce the photo's size at this point, because that would have added more distortion.
800 x 600 This photo is the result of applying the sharpen filter one time.	800 x 600 This is the result of applying the sharpen filter twice.
1200 x 300 Warning!! Be prepared to wait! Here's the comparison of all three photos. Original to the left, Sharpen X 1, then Sharpen X 2.
800 x 600 Here I cropped out a good example of the detail from each photo for closer inspection. I think the sharpening had the desired effect.	1200 x 900 This is the finished product. I applied sharpen filter twice, tweaked the contrast just a bit, resized from 1600 x 1200 to 1200 x 900, and saved in jpg format with a compression ratio of 35.
