Another year, another post about fire

My favourite annual festival is bonfire night. It's an event which knows exactly what it is, hasn't really been corrupted by commercial interests (cough Christmas) and is very local - that is, it's done at a village level and keeps its small-scale feel. It also comes with fireworks and a bonfire. I love it.

Every year I look forward to heading to my parents' village for their event (living in a historic city, there isn't much taste for huge pillars of fire ... go figure) and every year I take a load of pictures of the bonfire, trying to capture the flickering tongues, the heat and the evocative nature of a pile of burning wood in the dark.

This year, we had the fun of the bonfire going up rather quicker than expected resulting in a huge cloud of steam and smoke washing over the crowd then a fireball which was gloriously hot before the marshals hurriedly made us retreat, pushing back the safety rope.

For the photos, I tried a variety of approaches. I wanted to capture the moving tongues, so shooting a fast moving target, but it was all at night so I needed to be mindful of light capture. This year I got best results with a high shutter speed, to freeze the movement, and then countered the limited light by pushing the ISO up to very high levels to pick up everything I could. Obviously the flash was of no use and there was only so much I could do with a wide aperture.

I was pretty pleased with the results, and I always enjoy the technical exercise of trying to figure out how to set up the camera to take these shots as effectively as I can.

I also took a few with my phone, which went with a similarly fast shutter, but instead of pushing the sensitivity just applied AI and fixed it up in post. I think. Pixel photos are somewhat magic.

Anyway, here are the results:

Minchinhampton Bonfire 2022

And if you're interested, this is last year:

Minch bonfire 2021

Which was set up in a similar way, although using less of the extreme settings.

Maybe one day I'll figure out how to capture fireworks.

Getting off auto

I take a decent number of photographs and as well as running a monthly photograph website I am taking it increasingly seriously as a hobby. Most of my photographs are taken using a camera phone thanks to the convenience of it always being in my pocket and, although I've dabbled with manual settings and know (very roughly) what they do I've never really been able to get consistently decent shots on manual mode. Never one to have a hobby and not get nerdy about the details, this month I got myself a proper camera and went with my Dad on a course to learn how to get off auto.

Buying a camera is hard. There are a load of nearly identical models and so much comes down to personal preference at a time when one doesn't know enough to have a preference. Given how expensive lenses can be, this is also a decision about which ecosystem to buy in to. It's a similar lock-in to the Apple / Windows or iOS / Android world in that it's reversible, but change can be tricky, unfamiliar and expensive. I may write about this in the future, but for the moment my key learning was the big choice if buying an SLR is Nikon / Canon. I ended up choosing a Nikon 5600.

Not all the way off auto


I've played around with manual photography before and have a (very) basic understanding of what the various settings do. When switching to manual mode on the phones I've used, the interface has encouraged taking full control - that is handling aperture, shutter speed, ISO and white balance all at once. This has always been too many interconnected, unfamiliar settings to learn and embrace at the same time. Possibly the single most useful tip from this course was to view it differently - take control of one of these aspects and let the camera do most of the rest automatically. This gives priority to a particular setting and therefore set of techniques (indeed, the modes on a proper camera are called aperture or shutter priority so ... yeah).

Aperture


We focused on aperture, letting the camera adjust shutter speed automatically and making corrections for exposure with the ISO setting. A wider aperture (aka a smaller f stop setting) lets in more light, allowing a faster shutter speed. It also allows control of the depth of field, enabling the blurred background effect used to create useful negative space and draw attention to a specific area of a picture.

This is often seen in portraits. Some useful tips for portraits - the eyes are the most important bit and should therefore be in the sharpest focus. So far, fairly obvious. Less obvious is that the camera may well actually focus on the closest part of the face - the tip of the nose - so for a really good picture some manual adjustment is necessary.

Another counter-intuitive tip is that portrait pictures are best taken on maximum zoom or with a dedicated telephoto lens. This is because the longer focal length allows for a wider aperture and hence maximises the depth of field effect.

Results?


And lo, the results.

Or, for a particular example of the portrait stuff above:

Portrait
We had a lot of fun walking around Lacock and practising the specific techniques that fell out of playing with this one setting and the day did a wonderful job of demystifying the bewildering array of buttons on a decent camera. I'm looking forward to learning more.
