That full spectrum stuff is super cool! I wish you didn't need to modify your camera to do it... I went camping in the woods, and I did some star photography!
Lightroom helped me get better at the TECHNICAL side of photography by understanding why some photos worked beter than others TECHNICALLY. Lightroom has a lovely analyser feature that allows you to filter your shots by camera settings as well as other filters such as star ratings. I can look at my early poor roller derby…
The exposure time was 10 minutes at f/11; I'm planning to return to this spot and take an exposure that several times longer so as to get more complete circular streaking in the stars. I just recently bought a remote control trigger for the shutter so I'm having alot of fun with extremely long exposure photography.
