High ISO Which Works!"},"content":{"rendered":"<p>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.<\/p>\n<p>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&#8217;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. <\/p>\n<p>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&#8217;ve always found the resulting images to be just too noisy.<\/p>\n<p>However, I&#8217;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 &#8220;Pixie&#8221;, a hot pixel remover), and a black point adjustment to make shadow areas truly black.<\/p>\n<p>This picture of the Fab 5 is from last year&#8217;s Barbados Reggae Festival, and was taken at a range of about 30m.
