Take a look at the above shot. Those flecks dominating the top right corner of the frame are sadly not a feature of the instagram-style filter I sadly had to use to make the shot even remotely work. Yes, I had crap on my lens. Normally this wouldn't be too much of a problem because at typical exposure, there's enough light coming through the lens to eradicate it but for a HDR shot, the underexposed frames are already limiting the light coming into the lens so the specks show up more. The HDR software then picks up on these details out and exacerbates the effect.Obviously the solution is very simple- one of those inespensive lens pens/cleaners. Hama do one for all of £7 on Amazon which I've picked up since (and can recommend) but sadly it doesn't help those photos I took at the time.
