I'm working on a YouTube video showing how to remove noise from an ISO 1600 blue hour capture by combining multiple captures and adding some focus stacking into the fray to make up for shallow depth of field at f/2.
Here's my work in progress so far. I thought I'd use the time-lapse sequence of Eltz Castle to create another image, this time around a bit darker (it was dark, after all) but without blurred clouds and with stars clearly visible.
What do you think?
EDIT: Ok, just noticed that the color profiles are all over the place, need to look into that. It actually look like in the second picture, which is a straight screenshot.
Fantastic image Thorsten. But not sure what you want to achieve by your settings. I understand that you probably do need to do a couple of shots to stacks, but surely not many? Also if you have a tripod you could lesson that ISO (and therefore the noise) and compensate with the shutter, making an interesting sky. Unless of course you wanted the clouds to be fixed. Still I love the shot, lucky you living near there!
Thanks Loretta! Well, this is taken from a time-lapse recording, I had to stick to a 5s interval, so 3s was the slowest shutter time I could pick, which left me with ISO 1600. I found out that I can completely obliterate noise from these shots by median stacking them, which will come in handy in the future I'm sure - just think milky way, where you are in a similar situation.
Great pic Thorsten. Good to see you post your photographic triangle data. This site is called F stoppers but we don't always get many Fstops actually posted.I kook forward to your youtube video.
Thanks Geoff! Well, there's a good reason I chose that as the title of my post - f/2 implies shallow depth of field, ISO 1600 implies noise and 3s implies motion blur.
Yet due to the fact that I have a couple of frames to play with I can completely overcome noise and shallow depth of field, the resulting picture is sharp front to back and shows no noticeable noise.
Contradiction? Sure. Impossible? No.
Very well done. I noticed the sharpness all the way through and wondered. I know that when you focus on infinity, F2 doesn't matter about depth of field, ie. if all of your subject is sitting on infinity. The lead in certainly isn't at infinity.You have a great grasp of this stuff.
