For this challenge, let’s go to extremes. Post a photo where you’ve taken some aspect of the photo to an extreme. Push your ISO as far as you can or, use the very short or very long end of your zoom lens, use your widest or narrowest aperture or determine how long of a shutter speed you can hand hold... Challenge yourself to go to several extremes at once or to improve your technique to better your previous day’s shot. Note in your post what extremes you’ve used.
