I used my Sigma 10-20mm and Canon 50mm lenses for this exercise and stood with my back to a wall to keep the viewpoint the same. I kept the aperture at f22 in all photos to avoid pushing the further parts of the image out of focus and partly because the visibility was so poor.
As you progress you feel as though you are getting closer to the water’s edge but the field of view becomes much tighter so it’s almost like the scene is closing in on you. My camera has an ASP-C sensor so the focal lengths used are cropped, therefore giving a slightly longer focal length than stated.
The 20mm (which I believe is acting like a 30mm using the 1.5x crop factor rule) feels closest to normal vision in zoom but the 50mm (which I believe is acting like a 75mm using the 1.5x crop factor rule) has a more natural field of view.
For this exercise, I used an 18-55mm lens.
I started with the focal length at 55mm and then switched to 18mm and walked forward until the subject filled the same space in the frame. The first thing I noticed is the compression on the subject is much more flattering to the subject at 55mm although the field of view is much tighter. At 18mm you have more of the surrounding context in the picture but the face is distorted.
The low angle of the camera in relation to the subject can be seen to exaggerate the natural triangle created by the subjects posture. From looking at photos within my own research I have observed that men are most commonly shot from this lower angle, giving impressions of height, power and importance. I feel it has worked for this particular portrait shot but had I have taken the image from a lower angle and closer to his feet it wouldn’t have worked so well.
I like using the Canon 50mm lens because you can set the aperture to f1.8 and it allows you to push backgrounds completely out of focus. I like how these came out, the first one came out the best as the focus is very crisp on her eye but I slightly missed it on the second.
For this exercise I used my Canon 50mm as you can use f1.8 to really emphasize the out of focus part of the photos.
Your eye is naturally drawn through the photo in the second photo as that is the part that is in focus but with such a large portion of the photograph being out of focus, it quite uncomfortable to look at. I find the first image more interesting because, although the colour contrast draws your attention first, you don’t linger on it as its out of focus so you start to scan the rest of the photo and see the interesting textures.
I used my lensball as the point of focus and I used the Canon 50mm at f1.8 for the first photo, f20 for the second and f22 for the third. I found that the first photo doesn’t really work as you can see that there is something in the background and it’s uncomfortable to look at the blur but the second and third photos go the other way, the background has a soft focus that is more comfortable but not quite soft enough to draw the eye to the ball that is in focus. If I was to do this again I would try and find somewhere in between.
For these photos I used a tripod to keep the camera still and a remote to stop camera shake when taking the shot, set the ISO to 200 to reduce noise, sigma 10-20mm lens so I could use the 10mm focal length and between f20 and f22 to create the deep depth a field.
My initial thoughts are that I haven’t quite managed to keep the whole frame in focus and I think there are a number of factors, firstly this isn’t something I have tried to do before so lack of practice, secondly its not a very expensive lens so there may be limitations because of that and thirdly the weather was poor as you can see over the background it was raining and the light was starting to dim because of the cloud cover and because of this the shutter speed was slow and there was wind movement in the bushes blurring the image. It is definitely something I will explore more in the future.
