Coed Walk

Introduction

Three 35mm photographs from a Carlo walk on 21 April, with commentary on the Padlock close-up.

Padlock

This is padlock on one of the garages at the Coed end of Granville Terrace. It was taken at 19:34 with the 35mm lens in aperture Priority mode – 1/100s at f/2.8, ISO 400. Some extraneous background has been cropped out from the left and bottom.

Padlock

1/100s at f/2.8. ISO 400

The colours are really nice, but there is a focus problem. I think there are two issues:

Composition Decision-Making

It isn’t really obvious what was meant to be in sharp focus. Is it the padlock, the bolt or both? A bolder, clear decision before taking the picture would help.

Depth of Field

When you’re this close to the subject, even f/2.8 is going to give a very narrow depth of field. The camera was probably only 30-50cm from the padlock. Some figures might help to reinforce this point:

  1. At 30cm, the total depth of field is only 7.3mm. 3.6mm in front of the subject and 3.7mm behind the subject.
  2. At 50cm, the total depth of field is 2.15cm. 1.05 cm in front of the subject and 1.1cm behind. That’s still not enough to get the padlock and the bolt.

Follow up to Silhouette – Focus & Depth of Field

As a follow-up to the focus and depth of field comments in the previous post, here’s another effort.

Better Focus & Depth of Field

1/400s at f/8

This picture was taken at 19:24 on 12 April. The idea was to capture the last of the sunlight on the top branches of the tree.

The narrower aperture and more careful focusing on the hight branches paid off.  There would have been scope to close down the aperture even further in order to put more of the tree in sharp focus. Still, it’s better – and the light on the top branches make it a slightly more interesting composition.

Silhouette – Focus and Depth of Field

This is a set of silhouette photographs taken on 10 April 2012 in the Cae. There are some lessons to be learned about composition, focus and depth of field. There is also a more fundamental conclusion: it’s important to take the time to plan a photograph, prepare the camera accordingly, consider the scene and then, finally, shoot deliberately.

Subject

As shown in the landscape version below, the subject is tree branches silhouetted against the evening sky. The pictures were taken at around 7.30pm on 10 April 2012. The sun had not quite set, but was obscured by clouds on the horizon.

Preparation

There was no particular plan for these pictures. The camera had just been used for Carlo photos and no time was taken to make proper adjustments to accommodate the change to a landscape scene.

Commentary

Focus

The biggest issue with these pictures is focus. They were taken with the 35mm 1.8G lens, and the aperture was left at f2.8. A much deeper depth of field would have helped keep things in focus.

Silhouette 3

First (and worst) version

Silhouette 2

Better focus

The picture on the left (120304_Portrait_3) has the most obvious focus problem. Focus was actually set on the sky, so the branches are blurred.

The camera was focused properly on the branches in the picture on the right (120304_Portrait_2). The shallow depth of field means, however, that the backlit cloud is quite fuzzy.

Composition

For all the pictures in this set, the idea was to try to catch the silhouetted branches and the backlit cloud.  In both these picture, a nice beam of sunlight is just about visible rising up from the main cloud. The view on the horizon underneath the cloud was cluttered and distracting. That’s why the bottom of the frame is much higher than it probably should be. It would have been nice to show more cloud and a straightforward plain horizon at the bottom of the picture.

The composition is OK in the left-hand picture. There’s quite a lot of cloud shining in the sunlight, and the branches fill the top half of the frame in quite a nice diagonal.

Unfortunately, less of the cloud is visible in the right-hand composition. Maybe having the top-right ends of the branches visible in this version is a bit better than just showing the branches going off the edge of the frame.

Best Version

Silhouette 1

Best Portrait Version

This is probably the best portrait version. The branches are in focus, but there’s still the problem of the shallow depth of field.

A reasonable amount of cloud is included and the sunbeam is quite visible. You can see one of the rugby training pitch floodlights at the bottom of the frame – directly below the sunbeam. That’s part of the cluttered horizon. It would have been nice to have at least the existing height of the cloud added to the bottom of the frame.

The shape of the branches in this photo is quite nice, framing the brightest part of the sky. The branches reach the top-right corner of the frame, which might not be ideal. This version and the landscape one above are probably the most satisfactory.

Conclusion

The photos were taken in a hurry and the aperture setting is wrong. Focus was also set on the wrong thing in the first version. Apart from those technical issues, the biggest problem is that the composition was hurried too.

There was no plan for these pictures and no time was taken to prepare the camera beforehand. Some more time taken to look at the scene would have helped. In summary, more deliberate shooting might have made these photos better.

Larger versions of each of the photos can be viewed in the Gallery below.

First Camera Outing

Introduction

These are photographs from the new camera’s first outing. They were all shot in manual mode.

The purpose of this post is to see what issues came up and to list them for future reference.

Issues

  1. Depth of Field
    • Even with the 18- 55mm f/3.5-5.6 kit lens, depth of field can get out of control. More care is needed when the lens is open more than (say) 5.6 – especially close up.
  2. Shutter Speed
    • It’s surprising how fast you need to set the shutter in order to properly capture motion.
  3. Single Shot v. Continuous
    • Moving Scottie Dogs are hard to capture in one frame.
  4. Composition
    • Lots more care needed here – related to #3 above.

Summary

I think a couple of themes are emerging already:

  1. It’s important to try and slow down and compose pictures properly. Where it’s difficult to deliberately shoot one frame, continuous mode can help.
  2. Shutter speed and aperture settings need to be more bold. Tentative increases or decreases are a bit pointless.
