Well, seems we disagree that time
. For me it's a great way to learn how to photograph, especially if you change some extremely small detail in those pictures.
I'd add IMO it depends also on a thing you're photographing. I personally experience objectives and small arrangements close to you are easier but especially landscapes are harder, since all the details are so tiny there. I do a lot latter ones even I'd say I'm still practising some way.
I think the biggest reason my multiple photos is still our camera and how it works. You can predict a little what kind of photo it's when you check the display after taking that photo, but the final quality in the bigger version can be horrible.
ETA: My very personal view is that some arrangement, thing etc that looks pretty good in small scale when activating the shutter, doesn't perhaps look that good in bigger scale. That's also why I prefer multiple pictures (some small parts changed, like I said) when practicing.
