I don't want to be a negative bummer here. I'm all for possitivity and if great shots like these are true, then I'm all for it. I was just looking at the comments on the website, and someone, which I also felt during the time reading... was this really taken for up to 15 hours of shutter speed open? First of, I don't know a camera can open to hours worth of shutter. Second, if so, it can, wouldn't it be over-exposed???
To my technical veteran friends, can you please explain how such is possible? :)
@yotan18 Lots and lots of ND filters... winter would help keep the sensor cool... as being open that long would make a lot of heat and heat means noise.... there would likely have to be an external power supply... perhaps even writing the information to a computer in real time.
under star light at EV - 6 you would need something like ISO 50, 4 hours f/11
so given the double'n rule f/22 means 8 hours and ISO 25 means 16 hours.. perfect exposure... so actual very do able... @yotan18
Love these shots. They are unlikely, however, to be 15 hour exposures - they are instead many shorter exposures (perhaps 5 minutes per frame) all joined together using commonly available software designed for the purpose. You can use some of the better remotes to do it all for you, so you don't actually stand there pressing the shutter every few minutes. A mate of mine does this (owner of a pro printing lab), and that's why the shots have no noise and also manage the contrasting aspects of day and night (in other words, why the foreground aspects aren't all blown out).
@yotan18 I think it was taken over 15 hours not open for 15 hours (so lots of photos of 30-60sec exposure, then merged. I could be wrong but that's how I read it.
I don't want to come across as a know-it-all, and I don't want to take anything away from the beauty of these shots (because they are lovely and well executed). However this is one of those techniques that is great for amazing friends and family because it is extremely easy to excell at, requiring, basically, about half an hour to read up on proper star exposure and the patience to sit out all night accompanying your camera and then running the results through merging software.
After said half-hour's reading, a less-than-stunning first attempt, I was able to come up with this second (and, for now, final) star trail shot... the result of just over an hour's time shooting. With more time, the trails would have been even more stunning.
Sometimes it's all about successful marketing. I'm just saying... :-P
@davidchrtrans Great shot...where would one find the 1/2 hour required reading (LOL)
But really tricks or not these shots are beautiful...I would never have 15 hours to sit & click remote or not but maybe an hour or 2 for something less dramatic to try

About a week later? Hmmm .... compulsive obsessive perhaps. Whatever it is, he's taken some fabulous shots.

Thanks a lot! :)

But still, sweet photographs.
