Has anyone else had any trouble with long exposures?
Taking some pics of a park in London > 20 secs they have consistently come out with an patch with the colour of smog. ie pale brown. I'll post some examples haven't got the leads with me in London.
I first noticed it some time ago but its time to find out more !the warranty runs out the 2nd Jan!
Oh dear, I haven't tried that one, just yet.
this thread's a bit o/d but i think you might have experienced some sort of reciprocity failure maybe. read
or have a look at www.photonotes.org that'll give all the technical info
this appears to have been a sensor heating issue.reciprocity only applies to film iiuc
I assume that these are at night, as you state > 20 secs.
The answer is no, I've not had any problems. Take a look at the set of nighshoots I took over the weekend..
Most were either 15 or 30 secs.
If they are not night, are you using a filter? e.g. BIG number ND?
hmmmm...sorry about that inexplicable case of brainfade.... <grin>
