As followers of my photography will know, one of my pet subjects is indoor entertainment, photographed by available light. I like capturing memories of enjoyable events, I love the colours of interesting stage lighting, and I like the challenge of trying to capture some of the dynamic nature of a music or dance event in a static image.
By its very nature, this means working handheld in low light levels, typically with long lenses, which in turn means a genuine need for high ISO settings. Even if I can hand-hold my favourite 300mm lens at a shutter speed of 1/25s (which I can, just about, on a good day, thanks to Canon’s excellent image stabilisation technology), 1/25s of a second is just too slow to freeze moving performers. I have several pictures with nicely sharp backgrounds and blurry main subjects to prove this.
With my earlier DSLRs, ISO 800 was about the fastest speed which would deliver a usable image, and that in turn meant speeds of around 1/25s with my preferred lenses. By comparison, my newer Canons should theoretically be usable up to around ISO 3200, giving me a reasonable 1/100s shutter speed, but up until now I’ve always found the resulting images to be just too noisy.
However, I’ve finally found a combination of sharpening and noise reduction techniques which works, and I can do it entirely in Bibble, my RAW processor. The magic mix uses a Wavelet sharpening algorithm, three separate noise reduction algorithms (Wavelet denoise, Noise Ninja and “Pixie”, a hot pixel remover), and a black point adjustment to make shadow areas truly black.
This picture of the Fab 5 is from last year’s Barbados Reggae Festival, and was taken at a range of about 30m. What do you think?

A month into iPad ownership and I have to say that although I love some of the things it does, my feelings are still mixed. Setting aside those features which, in my case at least, are really for personal use, Continue reading →

Reviews
I just realised I haven’t posted anything to my photoblog recently, so here’s one I’ve just processed from Barbados last year. I’ve never worked out why Foul Bay has its name – it’s a lovely long stretch of clean unbroken Continue reading →

I’m currently reading a book called “Beautiful Architecture“. This has at its core the concept that some software structures are inherently elegant, things of beauty as well as great function, like many of our greatest buildings. The trouble is that Continue reading →
I’ve just had a bit of excellent news – my submission for the 2011 Enterprise Architecture Conference in London has been accepted. The provisional title is “Practical Enterprise Integration – Realising the Benefits of a Strong Canonical Architecture” and I’m Continue reading →
I don’t know whether I’m alone, but I’ve had two separate problems with computer systems which didn’t survive the transition from 2010 to 2011, making me wonder if there’s a more generic “Y2KXI” bug, like the famous Y2K bug, only Continue reading →

Thoughts on the World
My brand new iPad died today. One minute I was taking notes on it. Next minute, dead as the proverbial fat bird with a big beak, or the Norwegian Blue (lovely plumage). There are three theories which fit the available Continue reading →
I’ve recently purchased an iPad, partly to satisfy some unrequited gadget lust, partly to satisfy some real needs for which I hoped it might be a good match, and partly to try and understand what all the fuss is about. Continue reading →
With Britain well and truly in the grip of Winter (where’s that global warming, then?), and more snow on the way, I thought this might cheer people up a bit! Continue reading →

I’ve just published my first plugin for the popular image processing suite, Bibble. CAQuest manages chromatic aberration correction, so if you find yourself always having to apply correction for “purple fringes”, this is the tool you need. To find out Continue reading →
