It seems to have been some time since I've written anything here. Time slipped so quickly through my fingers, I hadn't really noticed, although there was always that little voice in a quiet corner of my mind which tried to remind me occasionally. Strange that, how time and events seem to put a totally different perspective on what you're doing and how you're doing your stuff.

Yesterday evening there was a firework show close to here, part of the yearly fair activities. I took my chances to see if I could get some interesting and useful pictures of the whole event. All in all I"m satisfied with the results, please judge for yourself if you like the images or not.

I'd been doing a bit of reading recently, on time lapse photography and related subjects. In the future I'd like to do more of this kind of shooting, stars, movement and action brought back into aesthetically appealing ways. This was my chance. I'd bought a good quality tripod recently which might help me achieve this goal and was hoping to move my photography up to a new level.

And so it goes... from the information I'd received, I understood that I should be using a somewhat smaller aperture than I'd been used to, because fireworks seem to be a lot brighter than one would have expected. The indicated aperture would be f/11, I stuck to that all evening, the results were good and in all honesty I wasn't disappointed. With a slight caveat, but I'll discuss that later.

Next, I set all my camera settings to manual. Manual focus, fixed shutter speed and aperture, no noise reduction, ISO fixed to 200 and the white balance set to around 3000K.
(Still a bit of mystery to me though, why the camera white balance is slightly different to what Adobe Lightroom shows, need to look into that...)

I focussed my lens on the pontoon from which the fireworks would be released, and left this untouched in the course of the evening. I set the focal length wide open at 24mm, to make sure that I didn't miss too much action by having to fool around with the right framing in the course of the show.

One thing I thought about beforehand, was minimising vibration whilst shooting the fireworks. Even though I have a very stable tripod, I suspected that the mirror slap of my camera would be enough to vibrate the image enough to produce some unsightly squiggles. In this case I used the exposure delay feature on my camera, which meant that the shutter would open only one second after the mirror had been released. It required a bit of guesswork and a little improvisation, but all things told I was satisfied with the results. One other small point of attention was turning off the vibration reduction setting on my lens, since this also reacts to the movements of the lens and camera.

At one point in the evening I decided to extend my exposure time from 2 to 3 seconds. I was hoping to get some longer and some more interesting trails, the net result though was that many parts of my images were seriously overexposed and had merged together. Perhaps a useful workaround in the future would be that if I tried 3 second exposures that I reduce my aperture to f/16 or perhaps even f/22. One big drawback yesterday evening was that there was a fairly strong air current above ground level, which moved both the smoke and the fireworks away at a fairly rapid pace. Will need to keep an eye on that next time.

In the end, most images needed a little bit of post processing. The main issue was cropping, since I'd shot the images as wide as possible and only needed a subset of the total field of view. A couple of images needed a slight exposure reduction of a half to three quarters of a stop, several needed just as much compensation in the opposite direction. More based on intuition than anything else, but it works fine for me.

OK, that's all for now. More photos from the last month to follow soon, especially some really good ones of the Dutch Rhönrad Summercamp 2012 where I was present to shoot much of the activity during the festivities.
Keep well...
