Thank you for the explanation. I wonder though why does Adobe or Gimp seemingly auto noise reduce my images when saving my work? I have noticed that if i dont use a sharpening tool, my images get softer every time i open them to work on them, or is this simply compression issues
Hard to know without looking at the samples, but in theory every time you save a .jpg the image gets compressed a little, which would make them softer. This was a problem 25 years ago, but you will hardly notice a difference today, especially if you save your .jpgs with the highest quality offered.
The 10" wide example was meant for people who are emailing images. For websites you have to go with a fixed pixel dimension (for example, all of the category images on the home page of the FriedmanArchives.com website).
Great history and information, Gary. Thank you.
Thanks professor!

Great information, thanks! But why do you talk about 72dpi and 10" when you want to use an image of a certain pixel size for the web?
