Motion: Capturing and Blurring / by Amanda Liew

Another thing we've been learning about in Digital Photography is capturing motion and blurring motion. In order to capture motion, your shutter speed must be very quick (to capture the motion instantly). This is usually pretty easy to grasp. I personally find blurring motion to be much more interesting. With blurring motion, you set your shutter speed to higher/slower. So instead of a quick shutter speed of 1/120, you can do a shutter speed of 2 seconds, 5 seconds, etc. I just started experimenting with it today, and luckily I have great friends to help me out! In this photo, I had the shutter speed set to 4 seconds. I had Janet cover her face for 2 seconds, and then remove her hands for 2 seconds. This is the effect! Notice how her face is the same throughout the entire shot, but her hands (what is moving) is transparent. Image

Something important to note is that with a longer shutter speed, a lot more light is coming through. Therefore, you're going to have to offset all that extra exposure by turning down your ISO and making your aperture smaller. I had to use a ISO of 100 and an aperture of F22. (Remember the larger the F-Stop, the smaller the aperture).

Here,  I had a shutter speed of 6 seconds where I placed the "M" in each position for 3 seconds each. I'm a little bummed about this photo because even with an ISO of 100 and an FStop of 25, it still looks underexposed. I can process it a little bit, but our professor wants us to gain the technical skills first before we start playing with Camera Raw & Photoshop.


This photo is capturing motion (Shutter Speed: 1/250, F/3.5, ISO 1600). Ideally I would have liked to make the shutter speed even faster so that the picture could show all of her hair strands without blurring them, but I was hesitant to make the ISO any higher for fear it would come out too grainy.Image

I also had a little bit of fun setting up my own studio in my housemate's room (she has the best lighting with her bay windows!) and played with sprinkles. (1/200, F/3.5, ISO6400). This time around, I wasn't as concerned with the high ISO since I was only shooting sprinkles and a non-descript bowl. I'm not sure if that's the right way to be gauging things, though!Image

And finally, my favorite image of the day. I made Janet slap Kevin a couple of times, but none of the photos really came out. Still hilarious, though! Image
