I think this might have been done to death, but I am totally bamboozled by the slow shutter speed write time. Thirty seconds is fine, and I get instant view. the moment I go to bulb and over 30 seconds, the 'gears' start whirring away. I have turned of the NR for slow shutter speed to no avail. Yesterday I put the setting to bulb and went out in daylight and exposed for 40 seconds, just to see what would happen. Well, off went the gears again, and years later the image appeared on the screen. (yes it was blown out but that didn't matter). I wonder why in daylight it has the same problem, if there is no black for it to read. (as it is explained that the buffer thingy is reading the black during that hideous write reading). What I also don't understand is this: last year we went to a light show. The fellows said turn off the NR which we all did. Not one of the exposures took time to read, and I had instant images, so I was all ready for the next shot. Here is an image which was exposed for 44 seconds. We also did some star trails, and painted trees with laser lights. All were exposed for more than 30 seconds. I just cant work out what I did then, that I obviously am not doing now. The image below was at 100 iso f11 on 'pattern'. I assume the latter is the metering? I am using a Sandisk extreme pro, which is the same card as used in the image below.
So if anyone can shine some light on this, (ha ha) I would be most appreciative.
