Just completed a bunch of quick image quality degradation experiments using various techniques following last week’s consultation with Randall – some working much better than others.
Results as follows:
#1 – Window screenshots
Didn’t quite give me the image degradation but produced an interesting stacking effect nevertheless.
#2 – Manual screenshots
I tried the same idea again but this time using manual screenshots (not screen grabbing the entire window). Almost negligible difference in image quality.
#3 – Save For Web at ‘Low’ settings
This method gave me very similar results to method #3. There was some loss of image quality when observed unclose but it was not at a level I was hoping to produce. Could possibly work if I saved it numerous times over (100-200 times perhaps?)
#4 – Resizing
This method produced the most dramatic of results. I resized the image to a small pixel dimension of 49px and enlarged it subsequently to 1965px. Mostly my preferred method amongst the four attempted. I can control the rate of the degradation by altering the range I reduce and enlarge the image.
