Camera Review – First Thoughts

Posted by Caz on Wednesday, 21st February 2007

As previously mentioned, my new digital compact is a Canon IXUS 850 IS, and having had it for about 10 days, I can now put down some initial thoughts on its features and ease of use.My main reason for the purchase was so that I could take it to the likes of PubStandards and BarCamp, or other conferences, as a lightweight and small alternative to my EOS 350D SLR. Lovely though that is, when I’m out using it on a “proper” photographic day out, I was finding I often left it at home (or took it reluctantly) to such events.

The other side of the coin was the perennial problem – I wanted a camera which had a high enough technical spec that when I did see an impromptu picture of the more “arty” variety, it would be up to the job of recording the scene in enough detail so I would not be cursing not having the “proper” SLR with me. So I’ve been on the fence for ages, waiting for something to tip me off. Cue the IXUS 850.

It allows me to take manual control of things like the flash, (on, off, auto and even slow-sync mode); white balance, and most importantly, ISO speed. It has a decent zoom range, about 28-105mm equivalent in 35mm terms – which is fine for indoor subjects where I’m most likely to use it.

Most of the pictures I got at last week’s PubStandards XV were a bit grainy and dark – I turned the ISO up to 1600 as I didn’t want to use flash very much (you just get the rabbit-in-headlights look), but the ambient lighting was not very bright. As such, some were a tad disappointing, but to be honest, I think any camera would have struggled.

[grainy stuff with the flash off and ISO1600 selected]

I also did a few with flash, and these were generally better:

[ISO turned down to 400 and a bit of flash – fine for most party/pub situations]

So much for small venues – how would it cope with the prospect of a larger auditorium? Well, I’m happy to report that it’s performance at BarCamp was very impressive. Again, most of the time I left the flash off and was running at ISO 800/1600, but the ambient lighting was much better and so I got some nice coloured lighting and natural looking shots without the flash burnout and colour washout that can occur.

[ISO at about 800, taken from the back of the auditorium]

Admittedly, the auditorium wasn’t as big as some conference rooms, and there was a great rake to the seating so everyone was pretty near and got a great view.

Later on (much later, I think this one was taken around 2:30am), we were playing Werewolf and I experimented using the Slow-sync flash option. This sets the camera shutter speed to something like 1/15th or 1/20th, and fires a less powerful burst of flash, which balances the ambient lighting with a bit of highlight pickup.

[ISO at about 800, and a burst of slow-sync flash]

I haven’t really taken many photos with the camera out of doors (I don’t get out much!), but I did spot this scene whilst waiting for a train the other morning:

The tree surgeon was hacking bits off a tree 30 feet in the air. The swinging chainsaw was still running… I did a bit of Photoshop tweakery afterwards to get a better B&W silhouette.

Composition #1 – The Rule Of Thirds

Posted by Caz on Tuesday, 20th February 2007

Theory
Try to put the main point of interest in your picture at one of the intersections of the thirds.

Or devide the sky/land line on a 1/3rd 2/3rd ratio. Try to avoid putting the horizon half way down the picture.

Examples

[Over The Rainbow – horizon on the lower third, protruding flower is on the horizontal and vertical third intersection]

[Sunrise, Calanais – horizon on the lower third, sun is on the intersection of the horizontal and vertical third]

[Pienza Hillside – high horizon on the upper third]

[Pencils IV – point of focus on the left hand third, but half way up this time]

Composition #2 – Lead-In Lines

Posted by Caz on Tuesday, 20th February 2007

Theory
Try to encourage the viewer’s eye to go deeper into a picture. Lead the eye around the frame by using:
[straight lines, gentle curves]

[imaginary lines formed by picture elements]

Always make sure there is an object at the “stop” point where the line finishes, which reinforces the lead into something tangible.

Examples

[The Time Tunnel – lines converge towards the figure in the bottom left hand third]

[Sunlit Cloisters – imaginary lines formed by arches and shadows converge towards the two windows at the end of the corridor]

[The Long Trek For Water – curved line formed by the footprints lead to the figures at the water hole]

[Lights On London Hill – the snaking s-curve leads off into the distance, but the presence of the car heading towards us stops the eye wandering off too]

Composition #3 – Using Symmetry

Posted by Caz on Tuesday, 20th February 2007

Theory
The rule of thirds is useful for many subjects, but not all.

If you see a symmetrical subject, it’s often better to compoase so that the line of symmetry is right in the middle of the picture.

Take care to make sure the symmetrical subject really is in the middle – slightly off-centre and it will look odd.

Examples

[Transporter Bridge – I stood right in the middle of the roadway (waiting for the bridge to com back to our side) and got everything balanced]

[Southwark Roof – taken from the middle of the aisle, also showing lead-in lines pointing to the stained glass window at the end]

[Victorian Hangar – carefully composed, with all lines leading towards the window at the end of the room]

[Picture Window – sometimes you get lucky with two planes of symmetry – here the horizontal and vertical framing was very carefully controlled to be equal on opposite sides, even though the main content (the reflections) are not perfectly symmetrical]

Composition #4 – Framing Elements

Posted by Caz on Tuesday, 20th February 2007

Theory
There are two aspects to framing your pictures:

  • Make sure unwanted things don’t cut into the side of your photos – always look around the viewfinder (or LCD screen) to check
  • Pictures can be enhanced by carefully framing the view – eg. with tree brances



Examples

[Le Chat Qui Pêche – the foreground path and overhanging trees frame the scene top and bottom, and the leaves cover up some boring sky]

[Ingatestone Hall – the horizon is placed high up, while the tree and its shadow appear to wrap around the building]

[The Castle Keep – I moved into a position where the archway framed the buildings beyond and the sunlight reflected from a window appeared behind the lamp fitting]

[Scrum Between The Posts – a scrum at the other end of the field, framed through the posts, provided a shot which showed more context to the situation]
