Take a number of shots using lines to create a sense of depth. Shooting with a wideangle lens (zooming out) strengthens a diagonal line by giving it more length within the frame. The effect is dramatically accentuated if you choose a viewpoint close to the line.
Looking at Images 1 & 2 even though I feel drawn in to follow the lines of the track to their distant point, I still feel somewhat detached from the photos due to the high vantage point the photos were taken, unlike Images 3 & 4 which were taken at almost eye level to the lines. These last two images also increase the depth perception than the first two images.
Take a number of shots using lines to flatten the pictorial space. To avoid the effects of perspective, the sensor/film plane should be parallel to the subject and you may like to try a high viewpoint (i.e. looking down). Modern architecture offers strong lines and dynamic diagonals, and zooming in can help to create simpler, more abstract compositions.
Review your shots from both parts of Exercise 1.3. How do the different lines relate to the frame? There’s an important difference from the point exercises: a line can leave the frame. For perpendicular lines this doesn’t seem to disrupt the composition too much, but for perspective lines the eye travels quickly along the diagonal and straight out of the picture. It feels uncomfortable because the eye seems to have no way back into the picture except the point that it started from. So for photographs containing strong perspective lines or ‘leading lines’, it’s important that they lead somewhere within the frame.
Images 5 – 8 were taken from a bridge roughly 20 feet above the railway lines. When I look at image 5 the tracks enter and leave the frame without the feeling of movement in other-words a static image with no depth, as soon as you start to angle the camera as in images 6 & 7 the feeling of travelling emerges as the tracks want to lead you somewhere. Image 8 shows how depth perception can be completely removed the tracks are 20 feet below the concrete girder and bridge but the image has been flattened due a direct overhead shot.
