Blur & Slow sync photography

Definition

Motion Blur-Motion blur is the apparent streaking of rapidly moving objects in a still image or a sequence of images such as a movie or animation. It results when the image being recorded changes during the recording of a single exposure, either due to rapid movement or long exposure.

Shutter speed-Shutter speed means timing and duration of opening and closing of the shutter curtain at the back of the camera. A fast shutter speed will freeze action while slower speed creates blurring effect.

Aperture-The aperture stop of a photographic lens can be adjusted to control the amount of light reaching the film or image sensor. In combination with variation of shutter speed, the aperture size will regulate the film's or image sensor's degree of exposure to light.

 

Slow sync flash-Slow sync flash combines a burst of flash with a slow shutter speed. On compact cameras slow sync flash is often known as night mode and you can't control the speed of the shutter or the strength of the flash but you can with a DSLR.

Rear curtain sync and front curtain sync-Flash Sync Mode, including Rear Curtain. Cameras typically offer a few flash sync modes. The "curtains" below refer to the focal plane shutter, which has a front curtain which opens to expose the sensor to light, and a rear curtain which then closes ,shutting off the light exposure .

Slow sync

This series of photos were taken in the studio at college, for this shoot we used a tripod, artificial lighting-lighting box a black back drop and a light metre to get an actuate reading of the lighting for our photos.  For these photos i used an aperture of 8 and shutter speed of half a second and two seconds. I chose all of those photos because to me all of them gave of symbolism ozone person having two sides to their personality or for the top photo, two people becoming one person. For the top photo i choose i asked my models to walk in a line by each other and so this created the long line of their bodies between the two of them, which to me appears ghostly. The model on the right side of the photo can be seen more visibly as she stood still in that position for a longer time until the end of the exposure, where as the model on the left is less visible and more moulded into the ghostly line. The second photo is just one of the models standing but she went to move but i had a very fast shutter speed of 1/2 a second so the lens only captured her slightly turing. However i ended up liking this photo because of the symbolism and deeper meaning to it. For me its like the other side of a persons personality trying to escapes of some out of the main personality/side of that person. The last photo leads on from the second photo. Even though its a bit hard to notice, just to the left of the centre my models body can be seen but is very dark, which blends it into the background. And then on the right side of the photo she looks like she's almost holding hands with the dark figure, so to me this looks like the main personality escaped the other personality but that personality is trying to hold her back and stop her from escaping. I enjoyed this shoot and i would love to incorporate slow sync as a technique in my further work this year, but for my current project on the environment, i don't think that i would be able to use this technique in a relevant way to the idea of my project.

Motion blur

For my motion blur I decided to go and try it on cars as my slow-sync was of people and so it would have been reparative. For this I had a tripod, all of these photos were taken in a short amount of time and so had the same aperture and shutter speed of(---) However for the top photo of the blue car, I did zoom in to get a different frame. Because I zoomed in on the photo of the car I managed to get a smaller frame for it as it was a smaller object and the background of the photo is darker which allows the whole colour of the motion blur be visible and its not ever exposed like the other photos because the clouds are not visible in the photo which makes the tone more even throught the photo. The other two photos are of larger vehicles so I had to zoom out in order to try and capture as much as possible. I choose the photo of the bus because I thought how the bus covers the last half of the photo was different to my others because I would normally capture them entering the frame of being in the middle, So I think its nice to see the majority of the back of the bus being in the most motion blur and so I have captured the colour of the bus in front of the building. I chose the photo of the van because it was just entering he frame of the photo, which has allowed for it to Cleary be motion blurred but you can still make out the shape of the van, and its not just coloured blur, which I like as its different to my others in this selection. The photo to me also appears to have a wide angle because the floor in the foreground of the photo appears to be curving, however for the both of the zoomed out photos I would prefer if the frame had been slightly higher, which would have allowed me to capture the whole bus. For this technique I don't intend on using it for my shoots because I try just to capture the landscapes without people being in the photos, but so far I have only completed two rural shoots, so depending  on my urban ones, it would be pretty hard and unrealistic to get all of my photos with out a single person, so if there is a person in the frame I may try and get motion blur from them if they are walking, or from a car.
