Freemasons' Hall Ceiling
Thanks, Cart. I used the magnification feature of the camera to attempt to align the image centre with the centre of the lamp/star. It is hard to ensure the camera is absolutely level when pointing straight up. The on-screen electronic level on my camera does not work at all in this position, so I am forced to judge by eye and also by checking the alignment of the straight lines in the image. I used Lightroom's guided adjustment feature to refine the verticals and horizontals to true. You can see from this picture that the lamp is suspended from four chains and is itself very deep. It is always possible the lamp may not be itself perfectly vertical or perfectly centred, and even a slight tilt (or camera misalignment) on such a tall lamp will be noticeable when viewed directly below. It is annoying, for such a geometric image. -- Colin (talk) 09:17, 3 October 2017 (UTC)[reply]
I'm more prone to think that misaligned light fixtures are due to the resident electrician than your camera skills. :-) --cart-Talk 09:27, 3 October 2017 (UTC)[reply]
Nice of you to say, but I'm pretty sure I contributed to the error. If anyone knows of a way to ensure the camera is level, pointing up, I'd like to know. I wondered about taking a small spirit level and resting it on the front filter of the lens. Would get me some odd looks I'm sure. That wouldn't work for my Samyang fisheye, though, which has a bulbous lens and a curved permanently attached lens hood. I'm going to try one of those Arca Swiss clamps that have little levels on them, but don't know if (a) those levels are accurate enough and (b) I can fix the camera plate into them precisely enough for those levels to be relevant. The level on my phone camera is more sensitive (and useful in all orientations) than the one in my camera :-(. -- Colin (talk) 10:30, 3 October 2017 (UTC)[reply]
Whichever level you choose, you will have to sight it just like you do with a rifle scope. No tool is perfect fresh from the store. --cart-Talk 12:05, 3 October 2017 (UTC)[reply]
It seems to me that perfect levelling with camera pointing upward can be achieved with a NN (I believe u own one). - Benh (talk) 18:29, 3 October 2017 (UTC)[reply]
