Weeek 5 task – Shutter speed (and ISO) – Lucas Heslop

The image above is capturing my fellow classmate mid-jump. This was taken through the use of the burst mode setting on my iPhone. The burst mode is a tool that emulates fast shutter speed which in turn allows me to take many images at once in order to pick out the best result. The image came out okay, you can tell that the model is jumping based off his body language and movement however his toes are out of shot so his full body isn’t captured. Next time I would stand further back or use a wider shot so that I could capture the full movement.

This second image, is of the same model but this time standing completely still aside from moving his hands around to create a blur affect. In order to get this shot, I used a tool on my iPhone called Live Photo. This tool uses long exposure to mimic slow shutter speeds, and in turn can’t capture frames as quickly as a high shutter speed can, creating this blur affect. I believe this image came out at a decent standard. You can tell that the model is standing still aside from his hands moving and the blur affect is quite successful.

Shutter speed and ISO research –

The amount of time a camera’s shutter stays open to let light onto the sensor or film is known as the shutter speed. It is crucial when figuring out motion and exposure in a picture. In sports photography, for example, a shutter speed of 1/1000 of a second is perfect for freezing fast-moving subjects because it allows in less light. A lower shutter speed, on the other hand, such as  1/10 of a second or more, lets in more light and can produce motion blur, which is helpful for photographing nature. In order to prevent camera shake, a tripod is usually required during exposures of 10 seconds or longer.

Together with shutter speed and aperture, ISO is one of the three essential elements of exposure and describes how sensitive your camera’s sensor is to light. P oor ISO values, such ISO 100, show poor sensitivity to light and are best suited for bright settings or tripod use since they result in cleaner photos with less grain. The sensitivity of the sensor is increased by higher ISO values, such as ISO 1600 or ISO 3200, which makes it simpler to take pictures in low light without using a flash. But raising the ISO also results in more digital noise or grain, which may affect the clarity of the image. The ideal balance between brightness and image quality, as well as the lighting circumstances, will determine which ISO is best.
