Water Fountain Week - Day Five

51mm, 1/800 sec f2.8 @ ISO 320

Alright, let's try for another truncated lesson - For those of you not interested, stare at the pretty picture and move on! Deal!

K, so like in the previous lessons photos, you might notice something distinctly different about the water in this photo versus the water in the photo from yesterday. Today, you can see practically every drop of water as it falls, whereas yesterday the water looked more "misty", more "blurred", more like our eyes see it as it comes out of the tap. This effect in photography is caused by the shutter speed/it's exposure time or, in other words, how long the camera is "seeing the image for".

Now compare the exposure time of this photo (1/800 of a second AKA 0.00125 seconds) to the exposure time from yesterday (1/4 of a second AKA 0.25 seconds) and it may start to make a little more sense. The difference is that 0.25 seconds is a 200x longer exposure time then 0.00125. This is like the difference between you staring at a flower, right now, for 1 second versus you staring at a flower for 3 minutes and 20 seconds. That's a pretty huge difference in time. Ergo if your subject has any motion in it, like water, or fast cars, or athletes you are going to want to take into account the exposure time. Because the longer your exposure time the longer your going to see every bit of motion that is happening.

SO hopefully that helped. I won't be talking about ISO anytime in the immediate future but I will someday. Until then, I'll just go back to posting photos without commentary. See ya tomorrow!
