beewee Posted April 10, 2023 Share #1 Posted April 10, 2023 Advertisement (gone after registration) For the longest time, I’ve been using LR for iPad which lacked HDR merge but after getting a MacBook, I’ve been playing around with HDR and Panorama merging a lot more. I recently found a set of astrophotos that I had taken with the thought of eventually giving HDR a try but forgot about this set and just went back to reprocess them in LR. I’m pleasantly surprised with the result. Welcome, dear visitor! As registered member you'd see an image here… Simply register for free here – We are always happy to welcome new members!

Apparitus Posted April 10, 2023 Share #5 Posted April 10, 2023 I think the non-HDR version is better, for me, it looks like it has more dynamic range. Also stars do not have a black dot in their centers. Did you use any tracker? What is the exposure data? Quote Link to post Share on other sites More sharing options...
davidmknoble Posted April 11, 2023 Share #6 Posted April 11, 2023 A lot of folks use stacking to allow for shorter shots effectively HDR’d together. I used to do that when cameras were in the 6-8mp range, but I haven’t found a great stacking program for the current Mac OS X (unless someone’s has suggestions?). @beewee, have you considered trying a graduated ND filter turned upside down for this situation? It might allow a brighter sky with a dimmer foreground (i.e, highlights more like the top photo)? I love them both, great work! Quote Link to post Share on other sites More sharing options...

It might allow a brighter sky with a dimmer foreground (i.e, highlights more like the top photo)? I love them both, great work! I’ve never considered an upside down ND since it would totally crush the dark foreground and lake. It’s hard enough to get enough detail out of the foreground without making the noise too apparent. It’s also a lot less work to expose shorter for an HDR composite than trying to fiddle filters in the dark. Keep in mind that with a grad ND, you’ll need to experiment with many exposures to adjust the filter position and this all takes a ton of time. Lastly, for most normal astro scenes, the ground is usually a few stops darker than the sky. Edited April 14, 2023 by beewee Quote Link to post Share on other sites More sharing options...

The HDR composite was shot at: 1s @ ISO 800 10s @ ISO 800 24s @ ISO 6400 Single frame shot was 24s @ ISO 12500 All wide open aperture. 2 2 Quote Link to post Share on other sites More sharing options...
