@hannahm, what would have made you guess a 1/20 sec. exposure? 🙂 You actually guessed it correctly!
The reason I’m surprised is, most people would have guessed probably 1/1,000 at least, if not more! After all, it takes a very high (or fast) shutter speed to capture a water drop in mid-air! Just curious, did you have a good reason for guessing as low as you did, or were you just taking a wild guess?
Normally, unless you have a steady hand, you’re going to get motion blur with a shutter speed of only 1/20 of a second! To tell the truth though, since flash was involved, the literal exposure time was much shorter, even though the camera’s physical shutter speed was only 1/20 of a second. If you’re interested, I could try to give you the technical explanation… Actually, you could ask @emilym about it, I think that was covered in the lessons she had on flash photography. 🙂
Here’s a hint… Remember that any time you use a flash, you’re actually working with 2 separate exposures.
